[Q] Bluetooth not scanning - HTC Rezound

I have a weird situation and not sure if I may have done something to cause it (most likely). My rezound cannot see any Bluetooth devices when it does a scan. I've tried using most of the ICS and GB images out there and even went back to the stock ROM at scottsroms.com to see if I could get it to work again. I know Bluetooth works, because it will pair with a device if that device can scan my phone and start the pairing process.
Can anyone think of what would be causing my phone to not see BT devices?
My phone is HTCDev unlocked and I have the anan ra 3.14 on it for the recovery image.
Any help would be appreciated.
Thank you,

The assumption is that you have put the device that you want to scan into discover mode..... If so, then you may have a problem with the hardware.
If you haven't, the phone will only see devices which are in discover mode.
This may sound like an obvious thing, but I ran into a user the other day that didn't know that.

Completely understand the need to clarify. Yes, I put both the devices in discover mode and I press the scan for new devices continually.
I'm hoping it's a software issue since it works if another device handles all the pairing. That doesn't work with headsets though.
For instance, if I have my laptop search for devices, it will see my phone, pair with it and stream music from it. So it appears the hardware works, just doesn't scan, which I'm hoping (losing hope quickly) that it's a software issue.
Also, I have tried a few different ROMs on this phone, so I'm not sure if one of the kernel images may have messed it up or if the initial root software I used broke it.

[Q] - Ca-Fi Android Car Stereo

Does anyone have the Ca-Fi Android car stereo? It seems it was recently released. I really want one, and will probably get one.
ca-fi.com/en/
Im debating on ordering one too.... though they list a 800mhz and a 1.2ghz version. Seems the 800mhz version is the only one available
Wish XDA would make a section for it and some custom **** was done with it!
total junk. save your money
I got one yesterday and installed it. Save your money. Its total junk. Was definatelu rushed to market.
No android market (yes you read that right)
Navigation requires data connection either through hsdpa gsm 3g or wifi (meaning you have to provide data for navigation to work at all)
Voice navigation doesnt work (it asks you to install additional files via the market, which again doesnt exist so it fails)
Every time i start the unit it goes to fm radio even when i dont want it to. Force closing the radio app does nothing.
The list goes on and on and on. NEVER AGAIN

Oh that's disappointing. I'm still considering buying one, just to see if I can root it, and fix some of the problems that you listed.

I actually thkught about that too. Problem is you really cant connect it to a pc so any rooting work woukd have to be done via microsd card and run natively in 2.2. Not only that even if you root it theres no gurantee the android market would be installed as the "default" market. This means the voice navigation may never be solved.
Long story short, i am veey disappointed. :-(
that unfortunately, I wanted one for my birthday

Doesn't it have a USB port on it?
I made the same mistake of purchasing one. I have been unsuccessful in trying to root it. Z4 will just freeze the device requiring a power cycle. I attempted to connect via USB but did not have any luck using this method either. The problem is that the radio runs both USB ports in Host mode. This keeps it from showing up as a device when you connect it to a computer. I have tried both the front and rear ports with Windows and Linux.
I did manage to get the Android Market app installed. It took a good bit of work and involved copying the Google apps including first boot to an SDcard and sideloading them. The first boot app did break my home button, it currently does nothing and I can't figure out how to re associate it with the launcher.
Once I was able to connect my Google account, I was able to sideload the market apk. Of course, this required working wifi. The dumb device is configured for wifi using a wpa_supplicant file which specifies that 802.1x authentication is required. Seeing as I'm not using this on my wifi, I needed an app called wifi fixer to override this setting. I also needed to setup an unsecured wireless network because I couldn't get wifi-fixer to connect to a wep or wpa network. Once connected, the wireless was very spotty but worked long enough for what I needed.
After all this was completed, I was able to download an offline navigation app, copilot live, that would allow me to use the device as a nav while I wasn't sitting in the driveway connected to the wifi. I did try connecting to my rooted DroidX with CM7 using wifi tether but could not get the radio to complete the connection.
As shassouneh pointed out, it boots into FM Radio every time its powered on. This allows it to start playing music quickly, but is very annoying. I typically stream music from my phone over bluetooth which requires the volume to be much louder than when listening to the FM Radio. When you start the vehicle, the volume is remembered and will be deafening. The FM radio application is very buggy and it will take several attempts to save your radio presets with an acceptable name. It tries to use the digitally broadcast station information as the preset name, but often it just returns garbage. After trying some twenty times, I was able to get most of my presets to read the frequency and the FCC station name. (ex. 93.1 WPOC).
The touch screen is very disappointing. It's a low-quality restive type which requires that you touch below the point you're aiming for. This makes getting to buttons at the very bottom of the screen a challenge. I tried calibrating the screen, but was sent into and endless loop of touching the cross-hairs...
The "Phone" app has all the bluetooth configuration including pairing, contacts, music, etc. it is very rudimentary. The radio frequently fails to connect to my phone on its own and needs to be forced to connect. Sometimes the play button will start the phone playing music and other times it won't. I haven't found a rhyme or reason for it yet. It doesn't support AVRCP and as such you get three buttons when streaming music over bluetooth: Previous, Play/Pause, and Next. There's no indication of which song is playing nor is there any way to browse the music on the phone from the radio.
Overall, the device is absolutely terrible. Perhaps if I could root it, I could fix a number of its annoying characteristics and it wouldn't be so bad. I was most disappointed by the poor wifi and the FM radio at boot. There is such potential here to make an awesome device... Do not waste your money on this piece of garbage no matter how tempting it may be.
Bought one also !!!
I discovered that the product seems to be sold has with another brand :
http://www.ekoore.com/web/en/product/car-hi-fi-2/elija-2/overview-6.html
The point is that they are providing an update.zip containing files and probably could be used for rooting the device. Found the link http://www.ekoore.it/download/elija/update.zip in the italian forum.
From what I understood, this is a 2.3 device ...
Confirmed mine is 2.3.3
Tried several rooting tools (Z4, GingerBreak, Visonnary+, Universal Androot ...) none of these are working.
Wasn't able to dump the rom (no ADB, used terminal with RomDump V7.2) but found that there is a physical switch inside the box. I can have a message displayed "No signal received", just by starting the device while the switch is pressed. Didn't manage to konow if this is bootloader mode or not.
Found a Quick Start guide explaining how to build kernel and so on http://wendang.baidu.com/view/6545cb13a216147917112879.html
Chip TC8900 seems to be used widely for several chinese tablets. So rooting shouldn't be as difficult as it seems. My guess is that the only way to have it rooted is to modify the update.zip above....but I don't know how to do it !!
From what I understood, the radio, BT etc ... parts are not running Android and are something completely different. The only way to switch to an android environment is to go to navigate mode.
Guys,
I'm surprised, I've had this installed in my car for a couple months now and it works great and I do use it daily and thoroughly.
I have installed Android market (couple of minutes, easy to do), have my email, contacts, everything setup, I even get auto updates for installed apps
Bluetooth pairing with both my HD2's works flawlessly and synced all contacts from both phones
The dedicated iPod interface works great with my 160Gb iPod, I have a USB hub in the glovebox with a 2.5" HDD , WiFi dongle and 3g dongle all connected in.
Navigation doesn't require a data connection, I have a several different SatNav apps installed - some online and some offline, but I stick with Waze as I like it..., Waze unfortunately starts up in portrait but that's easily sorted with a press of the home key and Waze also puts up a single warning about battery being flat, but there's no battery, so what would you expect.....
can also listen to good quality internet radio on the move
If you buy a device like this, you've gotta expect a data connection to be required for initial setup of your apps and how you want them, I've run the device without internet, through my phone and through a 3g dongle.
It works properly and reliably with my original steering wheel controls and the way it sets this up is the best I've seen on a in car device and simplicity itself.
It also boots to the last source being played, in my case normally iPod, but if the iPod etc is missing, then it will default to the radio.
The touchscreen isn't the best in the world, but is very useable, if the alignment is out then recalibrate it by holding the back button until the calibration screen appears..
Only thing I really don't like is if you burn some mp3's to a cd/dvd, they play through the dvd interface, not through the android media players.
I genuinely like the unit, it's a nice toy to have in the car and has no more issues than any other android device I've used...
J
Should say that the FM quality is really awful ! Can't even get the RDS working ...
French translation is missing sereval items (or completly false). Got the wifi + market without too much trouble. The touchscreen is usable.
I definitely love to have it rooted

I've got that stuff from their dealer in Russia, I think juliabrothers.net
Cool device. I loved it sound quality, pure, very sharp image. Very quick response. Yes, the touch screen isn't as good as we used to have on smart phones. Still works o.k. Just look at others DVD player made on Windows CE6.0 platform. They ain't better in anyway.

Could you please give me a hint how you manage to install Market on that thing?
Still working on it. Which Android version do you have? I have 2.2
You see, Android Market which built for smart phones doesn't work very well for CAR stereo devices. That Market doesn't differentiate between "good" and harmful applications, which can shut down your system forever.
Remember most of software designed for smart phones doesn't work under CA-FI platforms. Supplier said so, I 'd be happy to be wrong.....

Is that possible to use that manual for building a kernel, which could be used instead of pre-installed software? Seems interesting. Any thoughts?
Market came from the 2.3.3 build already installed on device. You probably can try the apk within the update archive http://www.ekoore.it/download/elija/update.zip . As the italian website is quite slow i extracted it. From what i understood update seems to not working on all devices.
Regarding the manual, of course I was thinking it could help for anything like root, recovery image or enabling adb. But honestly i don't have enough knowledge to do myself.
Hi Everyone, just found this thread. I have this unit as well and have been building info on the MP3car site about it, overall i'm happy with the unit although i haven't been able to do everything i want to it.
The audio quality for me is good and i can tether data off of my phone to play internet radio and navigate through waze or otherwise. I'd definately like to see some development in this area myself as there are some welcome improvements to be made. i've sideloaded the market but was never able to update it. the player will default to the last built in media that was played when it shuts down and there seems to be several volume streams built in, i've heard people haven't been able to adjust these with volume apps.
here is the MP3car thread: http://www.mp3car.com/android-tablet/150109-innotrends-ca-fi-on-order-will-review.html
Upon request, here is the update zip from the italian forum. Rename from update.zip to elira-update.zip
elija-update.html
I recently purchased and installed the Ca-Fi "Universal" 620 to replace my JVC head unit that died after 5 years. Because there isn't much information out there about this product, not even from the manufacture, I thought I'd provide the good and bad from an audiophiles perspective(...and I only coin the term audiophile because I have a full on sound system in my car, not because I'm into the lossless debates and all that BS).
The Bad (or the ugly):
-Has an individual RCA jack for subwoofer output. (left/right(white/black, red) is pretty standard. Now I have to buy a sum'er to join the channels. What if I had two subs running left and right channels of bass...I'd be up a creek and would have to buy splitter then a line driver...blah come on.
-Although there is individual subwoofer level control there is no subwoofer (low) frequency control. So, my lows that run to my subwoofer are the lows that will run to my speakers and I can’t do this cause my front stage was meant for highs and mids.
-The Graphic EQ, although having 10+ frequency to set they provide automatic roll off of nearby frequencies so, it's hard to fine tune.If you’re going to give me that many frequencies then please let me control each one of them.
-The balance controls (and all other touch screen sliders)were OK but, they sorely need increase/decrease buttons (i.e. “+” and “-“). Trying to configure a good sound stage is hard with resistive touch screen sliders.
-The P.CNTL (I assume Power Control, again no documentation) is switched off and on when you change sources (or I think actually when no sound is “sensed”) whaa? So now, because my amps have delayed starts, each time I switch a source (or Pandora even buffers a new song) the relay power drops to my amps and I have to wait for my amps to power up again. Not to mention the pops because of the high current switching on and off..man. So now I have to find an off delay relay so my amps don't turn off when I change the source. Now I could very well be the idiot on this one and need to use the P.ANT (I assume power antenna) but, the reason I didn’t is because P.ANT is solid blue wire, whereas P.CNTRL is a blue with white strip which is more industry standard for relay control.
-The boot up source is always going to the Radio. I read some other folks already discuss that here and there but, come on, really, you can't just remember the last source I had.
-Bluetooth (or lack thereof) yes, it will play your music from your phone (in my case HTC Sensation) but, that's about it. If I want to change an artist or song or whatever I have to do it from my phone. I thought it would have this to make me a safer driver so I don't have to look/mess with my phone to get new songs, guess that's what I get for assuming?
-Auto screen Dimmer doesn't work or isn't that great cause I still have to manually dim the screen at night.
-Resistive touchscreen I gotta hammer the screen to push buttons. Each push takes my attention away from the road, no bueno!
-Wifi doesn't support WEP or WPA no biggie since I'm driving and I don't think hackers do drive by hackings (or do they?). But, still sucks cause when I use it at the airport I have to turn it back on. Just a nuisance but, wifi WILL tether (provided you buy the additional USB Wifi Adapter).
-Some Apps don't recognize my wifi connection and thus will not work. Case in point, Google Maps. wft! the whole reason I got the thing was to wifi tether with my phone and control goolge maps from ca-fi. Nope can't do it. booo.
-Double DIN – not really. I don’t know what standards they followed but, my original brackets from my original Double DIN HU (head unit) didn’t work. The unit sticks out so far my radio door won’t close and there’s a gap of about .25 inches on both sides. No install kits will work with this because it’s not truly a standard Double DIN.
The Good
-The bluetooth phone capabilities work good. Contact list is ok. Of course it sucks for me because of the whole P.CNTRL thing. Yes, when I switch to Phone it turns off and on my amps…grrr.
-Mini SD card slots and a miniUSB port in front, very nice/convenient.
-System isn’t as slow as one might think for such a “slow” processor. My HTC Sensation runs circles around this thing ;p.
-Nice interface for the radio.
-You can run Apps. Although a lot of them crash (i.e. Force Close) every now and then for no apparent reason.
-Pandora works (with wifi tether) very nicely.
-Push button (knob) for mute and knob volume control.
….that’s all I’ve got for now but, so far the goods don’t out weight the bads so, I’m not happy with regards to the amount of money I spent vs. what I’m getting vs. what actually works. I’m not upset because I went into this fully knowing I was going to be a guinea pig but, if you’re a music first, apps and other **** second, kind of person like me steer clear my friends.
Not that any manufacture ever cares or even reacts to forum post, I’m going to try and communicate this to the manufacture and hopefully see if a) they’re aware of these issues and b)if they plan to release fixes/patches to help their “new adopters” out. Don’t get me wrong this company has a great product and great idea but, they’re seriously mistaken if they think they can compete with the big boys (Android Apps or no Android Apps).
What do jou Guys/girls think about this product....... http://www.chinavasion.com/2-din-ca...chable-android-23-tablet-panel-wifi-gps-dvbt/
I find it very interesting

[Q] replace bluetooth stack?

Is it possible to replace the bluetooth stack? I am using stock 198_7 rooted, but locked with a few mods such as the hdmi hack. I find that my bluetooth cuts off intermittently. It's most annoying with my microsoft keyboard 5000, which then needs to be paired again. when it happens to the jawbone icon headset, I can just turn bluetooth on and off. Usually with that, it happens during netflix streaming. I do find that the microsoft mouse 6000 works perfectly.
I did try CM9 for a few days. I didn't notice any bluetooth problems on that. However, I can't use my webtop, which I use regularly. I also can't use netflix, which I am addicted to. So I was wondering if it were possible to switch. I tried swapping the apks, but it didn't seem to make a difference.
any thoughts/ideas?
Thanks,
I agree with you, the Motorola bluetooth implementation is terrible and needs to be replaced. I have the same problems as you with devices randomly disconnecting and reconnecting while listening to music or netflix. When I answer the phone the bluetooth doesn't pick up, I have to quickly hit the "Bluetooth" button on the dialer screen to turn it off and hit it again to turn it back on before my caller can hear me. I'm using a Motorola Droid 3 and I keep going with Motorola because of the keyboard, but these bluetooth problems are so aggravating that they may drive me away from Motorola. I had the same problems with my Droid 1 and I really want the Droid 4 but they've got to get these problems fixed. I even bought a Motorola headset, the HX550, hoping that there was just a compatibility problem with my Jawbone Icon, but the problems continue. Maybe just maybe we'll get the attention of someone who can fix it.
Logcat attached.
I've been having this issue since I bought the phone. I'm hoping someone can help. I've attached a succinct logcat of the issue, hoping to catch a devs eye. It seems completely independent of the ROM, GB vs ICS, or applications installed. I've tried everything out there and have started thinking about how to build a kang, but I don't know enough about the problem to know how to solve it.
I really don't know what else to do, but there are times where I want to throw my phone out the window of my car at 80MPH. I love my Photon, so that prevents the carnage, but OMG it's frustrating!
I'm hoping Sprint... or some entity in-the-know will release a resolution to this problem. I know it's a dead horse, but it only takes one moment of brilliance during a coffee fueled manic episode to have a break thru!
Thanks in advance to any devs looking at this.
This fix worked for me! YMMV
UPDATE!:
It turns out that the Bluetooth Share processes are interupting the data stream while the music plays. Since Bluetooth generally can't handle more than one thing at a time, I suspect that the share services are trying to make the connection do too much. This will disable your ability to share files and phonebook, but for me, those are all secondary to my tunes!
I found a solution here:
http://forum.xda-developers.com/showpost.php?p=18723490&postcount=16
And instead of freezing the Bluetooth.apk services, I just did the following in the terminal:
HTML:
su
cd /system/app/
mv Bluetooth.apk Bluetooth.apk.bak
Rebooted into recovery.
Cleared the cache.
Rebooted system.
And done. That was a lot simpler than I thought it would be.
Standard disclaimer: If your phone stops working, it is not my responsibility. I don't foresee any issues, but just in case, you have been warned. Good luck!
This is actually used in many different settings. Such as backups, removing problem apps, testing, many more. Nice you found a great new use for this.
The best thing about renaming the it to a .bak or .bin is that the app is still intact and is basically a backup and can be restored very easily.

[Q] Bluetooth carkit problem

I have a Galaxy S3 I9300 for a couple of weeks now and I love it, other than the fact that I keep having a strange issue with the Bluetooth connection with my carkit. I've been searching forums for similar issues and I found a variety of carkit related problems, but none of the ones I found describe the same problem as what I'm having:
- Initially the Bluetooth connection works fine and I can play music or make a call through the carkit just fine
- When I switch off the car's systems and don't use any apps on the phone in the meanwhile, and then start the car's systems again, it establishes the Bluetooth connection just fine again
- When I switch off the car's systems and I use other apps for a while and then start the car again, it won't work. Bluetooth does appear to connect, but after that it just doesn't play ball. When I try to play a song at this point, the phone shows the song is playing, but neither the phone nor the car audio produces any sound
So anyway, every morning before leaving to work and every evening before going home, I reboot my phone first. Then I step into the car and it establishes the Bluetooth connection just fine. But if I don't reboot the phone first, it just won't work. Now I guess I could setup a tasker profile to automatically reboot the phone, but I'd rather just get the problem fixed.
I run a Galaxy S3 I9300 with stock Android 4.1.1, rooted. I have already tried to run the "Bluetooth Fix Repair" app and afterwards had to pair the phone with the carkit again, but that made no difference.
Any help would be greatly appreciated!
*bump*
Some additional info:
This issue has now also happened a few times while driving. While music (through Spotify) was playing over the bluetooth carkit, it would sometimes just stop working when I opened a different app (like for example opening an SMS). Spotify was still running (and the song was still ongoing) and also the bluetooth connection still showed as being connected, but it just wouldn't produce any sound anymore.
Anyway, it seems clear to me that this is a bluetooth issue, but I have no idea how I can troubleshoot this beyond what I've already done.
I would be happy to pay whoever can fix this problem..
With an issue like you are describing it may be helpful to list the headunit model too. I do not own an S3 but I have a multimedia headunit (Pioneer AVH P4400BH) and have found that toggling my Bluetooth on and off will help the headunit to see the Bluetooth on my Android device. This may not resolve your issue though.
Another thing to consider, your headunit may have an update-able firmware. That said if your headunit does have an update-able firmware I would check out the procedure, ensure there is a way to roll back to your current firmware and try that. If your headunit was purchased at an electronics or and audio retailer you may wish to speak with them. Your issue may not be with your phone but with your headunit, but this should help as far as troubleshooting since your issue involves multiple devices.

My car is a Renault Megane RS, the carkit was built in. I believe it's called Renault Carminat TomTom.

Good point. It does have an SD card slot, but as far as I know that's only to update the maps of the navigation system. I'll see if I can figure that out.
Thanks for the tips!
By the way - I do think that it's unlikely that the carkit itself is the troublemaker. Especially because opening an SMS on my phone can trigger the whole thing to stop working (it doesn't happen every time, but it did happen several times). Please correct me if I'm wrong.

It is in fact very possible that it is your phone, but wanted to throw it out there that bluetooth headunits can be troublesome on their own. Now I am not familiar with your headunit, but does it save bluetooth IDs? Like on my headunit and many other aftermarket headunits, it will save 3 bluetooth devices. If it does, have you tried clearing other devices and moving your S3 to the top? Odd as it sounds this has made a difference for me. Also do you have other bluetooth devices in the car, such as the 3GS you mentioned?
Also a logcat of this happening would be beneficial. If you do not know how to pull a logcat there is an app on the market called catlog or alogcat. Both are free and are invaluable in troubleshooting a ROM issue. In short it tells a developer what is going on as far as events being triggered or failures within the ROM.

Yeah I had read that too in some other thread (I went through just about every bluetooth related thread I could find, before I posted this topic). Mine saves up to 5. It didn't have anything in there except for my previous phone, which I had cleared. I also tried re-pairing the S3 several times, that didn't make any difference either.
Now, I just read somewhere that some people are having disconnection issues on the same carkit. In their case, in the end the problem turned out to be that their carkit will import all of their contacts from their phone (so you can call people even while your phone is in your pocket), and this would cause trouble when there are contacts without a phone number associated with it (just like my thousands of Exchange contacts). The people in question are talking about random disconnects though, whereas in my case it happens after doing some stuff on my phone. So it's probably unrelated, but I'll give that a try anyway just to rule it out. I just need to figure out a way to stop the carkit from importing contacts, because removing thousands of email contacts is obviously not an option.
I'll keep this topic updated with any progress. If anyone has any other ideas, please keep em coming. Thanks for the help so far!

Also a logcat of this happening would be beneficial. If you do not know how to pull a logcat there is an app on the market called catlog or alogcat. Both are free and are invaluable in troubleshooting a ROM issue. In short it tells a developer what is going on as far as events being triggered or failures within the ROM.

Didn't think of that, great tip, thank you! I do run the stock ROM by the way.
I've installed alogcat just now. Does it just keep running automatically in the background?

It reads a file that is being constantly updated (which happens to be the logcat file). Typically I will clear it right before doing what it took to cause the failure, like in your case in your car with the bluetooth on.
I've got Audi with BT and S3 with custom rom and I've got similar problems with BT. It connects automatically but if I switch off BT in phone and switch it on again - it doesn't connect any more. I had this since I bought a phone and it was on all ROMs I used.

Yep - I have that too. The weird thing is that in that situation the phone does seem to think it is connected, while it really isn't. Just to be clear: this is not the only way to cause this issue (because it also happens when trying to reconnect the Bluetooth while on the phone it hasn't been disabled in the meanwhile).
So far I haven't been able to pull anything related from the logcat.
Also, while reading up on common bluetooth issues, I came across some posts of people who were saying that some phone/carkit combinations are having trouble with 2-way communication (because I can stream music from the phone to the carkit, but I can also change a song using the carkit or initiate a phonecall from the carkit). I'm going to try to only use communication initiated from the phone, and see whether that makes any difference. In the meanwhile: does anyone happen to know anything about 2-way communication issues with bluetooth, and how to overcome such issues?
Update:
- Updated carkit to latest firmware. No change, still same problem
- Have not been able to capture anything unusual in the logs
- I have a Bose Soundlink now, which is a wireless speaker. Whenever my S3 is connected to the Soundlink (with bluetooth), wifi doesn't work. Upon turning off bluetooth, wifi instantly works fine again. So this definitely confirms this is a problem with bluetooth on the phone, not on the carkit.
- Wanted to upgrade to Android 4.1.2 but Samsung won't let me, as it says the device is modified (rooted). Triangle away isn't helping. Damn you, Samsung. This is *the* reason I moved away from Apple, as I don't like companies who don't let you use your stuff any way you like. And now Samsung is moving down the same route. Idiots. Anyway, I guess the only option left, is to start using a custom ROM.
Does anyone happen to have experience in terms of solving bluetooth problems by using a custom ROM? I'm thinking of using Cyanogenmod 10.1
In the meanwhile I have upgraded to Android 4.1.2: still the same problem.
I have also discussed this matter with quite a few other Samsung smartphone owners, and all of them appear to be having the same issue. Most of them just don't seem to be bothered to spend time on looking for a fix.
Also, I have figured out that this problem is specific to media streaming. I'm able to use my phone on the carkit for calls at any time, without having to reboot first. Only when I try to listen to music, the problem occurs.
Anyway, I have ruled out that this problem is specific to me or my devices - this appears to be a global issue. So I'm completely puzzled as to why there's not a lot more fuss going on about this.
If anyone has any more suggestions for a resolution of this problem, please share.
S3 bluetooth connection problem
Had the same problem with my S3 and renault megane III handsfree bluetooth system.(Arkamsys software version 2.2.0.19 auditorium)
I downgraded to 4.0.4 baseband I9300CELH1 (stock) and problem seems fixed
hope this helps.
Hi Bennes,
Thank you for your response.
I'm still dealing with this problem myself. All upgrades so far haven't made a difference. So far, I've been able to figure out that if I first initiate a phonecall, after hanging up, the audio streaming works (while before the phonecall it usually wouldn't). This works about 8 out of 10 times (the other 2 times it doesn't make a bluetooth connection at all). So what I've done, is to use Tasker and to automatically make it call my own phone number whenever bluetooth gets connected to the carkit, and hanging up after 3 seconds. But this is obviously far from ideal.
Do you know whether it is possible to change the baseband version without changing the firmware version? I wouldn't like to downgrade to an older firmware version, as I like the new features in the newer versions. I do also prefer to stick with the stock firmware, but that's not a requirement.

mmm, don`t know about baseband only. Try google.
I have read that after downgrade to 4.0.4 and then upgrade again to latest stock version, bluetooth connection keeps working.
I cannot confirm this as i am still on 4.0.4, but will get an update of the arkamsys radio to the latest renault firmware version next week and then start experimenting again. i will report back once i have new results

[Q] Razr has no display - can I fix it?

A buddy sent me his Droid Razr Maxx after he dropped the phone and smashed it's glass screen. I'm trying to see what I can salvage from it. The phone does not show a display under any circumstances. It will boot up (I can hear the default boot up sounds). The navigation buttons light up. When I plug the phone into my PC the internal hard drive shows up. I can add and remove files. But so far, that's it.
I had hoped that I could use HDMI Out as an alternate way to see the screen but so far I can't make that work. I've got software that I've used on my own Razr Maxx to root it, to factory restore and to flash custom ROMs but I know that his phone was pure stock and I can't get to the settings I'd need to change to let the software "see" the phone.
What else should I be trying to get something from this phone? If I could make the phone functional again that'd be great, but even if all I could do was get the HDMI Out to work I'd use it as an Android computer on my HDTV (I've done this with my own phone and it's way better than the Android "sticks" but I don't like tying up my phone). Without any clue what's on the screen I've got no shot to do the things I'd normally do to modify the phone.

Ehm, the first thing I ask myself is: When the screen if broken, how do you want to use the phone?? Also when you get output on your TV - the touchscreen wouldn't work (I guess).
However, I would read the logs first, especially the kernel logs (dmesg, last_kmsg) via adb shell, and see if I can find something related to the screen. The stock kernel has DSS Debug ON, so you will see several entries in dmesg in case that the touch device responses to the kernel.
You can slo control most functions of the device via adb shell - i.e. enable HDMI (assuming stock (based) rom is installed), install and run apps, debugging and much more. But you need to know how to use it of course.

As to how I'd use the phone, assuming that the touch screen cannot be resurrected, if I can activate HDMI Out then I'd use the phone as an Android "media device" on my HDTV. This is the main reason I wanted the phone in the first place. I've read up on the Android "sticks" that plug into HDMI ports on TVs and then you can stream Netflix or access a browser, etc. They all need a separate power source (via USB usually) and most of them get poor reviews for wifi reliability, root-ability, etc. But since I've already used my Maxx HD in precisely this way from time to time I know that an Android phone could do this same thing, probably better. Assuming I can get the main functions of the broken phone to work I'd activate Bluetooth to connect a mini keyboard/touchpad. I've used that on my Maxx HD. That way you can control every phone function without ever having to touch the screen.
I've never been very good at adb shell unless I was simply trying to follow precise directions but I think I understand what you're saying about being able to input some commands using that approach. I'll read up.
I guess you are talking about the mini PCs with android. I'm. Not sure but I would say they have correct drivers for remote control - the razr would need that in its kernel first.... Only my thought.
But a keyboard or mouse on Bluetooth could work - assuming you can enable bt in the phone without using the screen..

I have the same issue with my headset. Hope someone will find a solution soon.
I too have same problem!!
Whats wrong with samsung!!, sometime Wifi problem and sometime bluetooth.:silly::silly:
earlier I was on 4.1.2 and it was working good with my jabra clipper bluetooth headset, after updating to 4.4.2 it sucks!.
according to my observation,
The OS is trying to save battery by limiting the bluetooth signal strength!, and the same problem with wifi also.:silly:
Looking for a workaround. If i find any will post for sure.
I have the same issue with my Note 2 after update to 4.4.2..
It seems to be a distance problem with my headset, every distance more than 50 cm creates
sound break up´s .. In my car the phone has a fixed place, it happens too, but not this much.
Maybe it is caused by a lower power managment for BT after update ?!
Found some others having the same issue e.g. here

Hi
and have the same problem with the bluetooth, the phone in my pocket, Samsung headphones on the head and lose the music signal, conclusion .... android version
Before to upgrade I had 4.3 and works very well and now I upgraded to 4.4.2 my Note 2 with Phantom_V7.0 and work awesome but has a minus....... the bluetooth signal gets lost and it's not about the power,for ex i have battery with 4200 mAh
I will continue to keep looking this problem and I will return
There is no way to get better connection. The only way is using a 4.3 ROM
Seems like the problem is solved.
Hey guys!
It seems to me I’ve found the solution!
But firstly, a few words about the problems I’ve got…
I have Samsung Galaxy Note 2 and, when I decided to replace my old Plantronics Discovery 975 with their Voyager Edge, it had installed Android 4.3.
Both events, start using the new Bluetooth devise and upgrading to KitKat (4.4.2) occurred almost simultaneously, so it was pretty difficult to recognize what was the source of the problems that I run into – hardware/firmware issues of Voyager Edge or KitKat’s quirks. The problems were the following:
- Poor Bluetooth connection that resulted in distorted sound (not always, but often) thru the headset.
- Regularly losing the ability to use various Edge’s features, such as calling back to the last number, checking the battery status, recognizing who's calling, etc.
- Note’s battery drained badly – instead of 50-60% left at the end of the day, I got 10%...
I spoke several times with Plantronics support, but they ended advising me to replace the headset. I have neither found the specific solution in the internet and it was even reported that the factory reset would hardly help. So, that was almost the dead-end. But there was one pretty weird solution that helped to some people – deleting the duplicates in the phone’s contact list. But, since I had NO duplicates, it didn’t seem to be helpful. But then, I noticed one very strange detail – during the moments when Edge worked properly it correctly pronounced the names from my phone book, even tho some of them were quite unusual for English speaking "robot". All of them, but one – my mother’s record, which was a simple “Mom”, but when she called me, the Edge’s notification was definitely not “calling from mom”…
So, I just renamed “mom” to “mother”!
Guys, can you believe that, but ALL the problems (both phone’s and headset’s) have just gone! I’ve been using it for almost a week already and it’s OK. So, you may check your contact list, whether it sounds correctly.
Well, one issue left – weird/funny bug of the Edge’s firmware – start playing music when you take it off the cradle. (2 latest firmware updates didn’t cure that…). I just long press the voice button on the Edge to pause it. Not a big deal, to be honest.
Oh, just one last note – since Voyager Edge cannot be rebooted you can do the following if/when you neither hear the music (!), nor the report that the headset is connected when you take it off the cradle. Just long press the Call button on the headset (in my case it runs Note’s S-voice) and then everything works just fine. (Checked twice.)
Hope that this will help you too.
Cheers,
Max
Hi Max,
nice story, but I can't belive that this entry or change of entry will make the BT signal better.

Hi Harvey,
Absolutely the same reaction was mine, when I read the comment by dawolverune (see page 1 of this thread). How deleting duplicate contacts might help…
Well, if assume that I tell the truth (and I actually do! ), then the solution may be explained in 2 ways: a) logical – I’ve been hammering with all this stuff for almost a week and nothing helped until I renamed that single contact and then, it just start working and b) technical – since Voyager Edge pronounced the wrong name it means that it took it from somewhere, but definitely from the wrong place and this might require extra “efforts” from the Bluetooth receiver/transmitter, etc. This indeed may result in abnormal behavior of the devise and “eating” the battery. If re-phrase the title of S. Coppola’s movie – here we had “Lost in Bluetooth” case.
Cheers,
Max

SOLUTION OF BLUETOOTH DROPPING after 4.4.2 update
Yo !
I found the solution. No one has to downgrade Note 2 (N7100) to Jelly-bean in order to fix the Bluetooth range and WiFi dropping issue.
The fault is with the latest update from Samsung itself, May be it is a tactic to make people shift to the newer phones.(who knows) !
Anyway the solution to this problem is to Flash it with Odin it a previous release of 4.4.2.
In my case which is from the INU (India) region the release of August that is 29.08.2014 is a faulty update.
So i downloaded the older one and flashed it.. then everything worked perfectly as if the phone was new
Here is how to do it:- [BACKUP YOUR PHONE WITH KIES 3]
1. Check your version from *#1234#, Compare the version with Near August version of your Region. If it is same you better change it to get a way better performance.
2. Look up the earlier ROM version released from samsung-updated .com , http://samsung-updates.com/device/?id=GT-N7100&details=Galaxy_Note_2__International , I personally flashed it with the first version of Kit-Kat that came for note 2 in INU region. on the 8th April (08.04.2014).
3. Download ODIN http://www.mediafire.com/download/mbvtjub21ehsxrl/Note+2+Odin.zip
4. Install Samsung USB drivers http://www.mediafire.com/download/9qaqkld45387lzi/Skyrocket_GSII_ADB_Drivers.zip
[IF THE LINKS DON'T WORK then GOOGLE THEM AND INSTALL]
5. Power off your Samsung Note 2.
6. Hold Volume Down, Power, and Home Buttons at the same time. You will enter the ODIN DOWNLOAD MODE on your phone.
7. Press Volume up to Continue. It will Show "Downloading" "do not power off"
8. Connect your device to the PC where you have put ODIN and the md5 file (Firmware you want to flash with)
9. It will show connected to your device name on the top left of ODIN which means that it recognizes your device.
Click on PDA and select the firmware that u downloaded to flash Note 2 with.
It will lag for a few seconds but let it take its time.
When it is done. [Refer Image attached]
10. Press Start [It will take around 5 minutes, 3 minutes give or take]
11. It will Automatically Reboot your phone. Do not disconnect the USB cable.
After the boot is Complete ODIN will show a PASS on the left Side. Which means that the Flashing Process has been a Success.
If it shows fail then Repeat the process from STEP 6 all the way till STEP 11.
{ RECOVERY STEPS:- this will wipe all your data}
[Also, If device is Stuck at setup connection or on any other process, then disconnect your Note 2 from PC, close Odin, remove phone’s battery and put it back inside AFTER 5 seconds, press Volume up, Home key and Power key at the same time, When the Logo comes then Leave the Power button but keep pressing the other 2. Wait for it to show MANUAL MODE. Select Wide Data and Factory reset with Volume down and press power to continue, Then again wipe Cache.
Select Reboot . Now it should work perfectly.
CAUTION :- DO THIS AT UR OWN RISK.
Is this problem appears in official update? Want to update, but dont want any probs)
Yes the problem is with the official update. Better not update it till there is another update of it available.
I'm thinking this might have to do with Samsung dropping the Bluetooth version from 4.0 back to 2.0. I have no idea why they would do that but I've been wondering why my phone listed version 2.0 when the specs for this phone always said version 4.0. As you can see my debug screen shows it as version 2 and not 4.0. My Edge shows 4.0 on that same screen. I can't recall if older builds for the Note 2 had 4.0 listed but I believe they did and kitkat lowered it. Guess that's their trick to get people to upgrade, break things on our phones quietly...
