[Q] Why a USB connection disconnects Bluetooth? - Galaxy S II Q&A, Help & Troubleshooting

Sorry if it is a stupid question, but I am completely new to S2/android and can't find an answer anywhere.
Is there any reason why placing the phone onto the craddle (which is connected to my PC via USB) comes up and ask me to disconnect Bluetooth? Why is it not possible to use both USB or bluetooth at the same time?
All my previous phones could do that but they were all HTC and all Windows Mobile phones. So I am not sure whether it is an issue with Samsung or Android or I just haven't configured it correctly.
I normally have the phone in the craddle while working (so it charges and can transfer files to and from) and use the bluetooth handset to answer or make calls. It is pretty annoying to not be able to do that anymore.
Thanks.

From what I can tell it's a thing with the Samsung bloatware they put on the phone, as I just tested it with my phone and I can have bluetooth, wifi and usb all connected at the same time. Perhaps try flashing a new Rom?

Actually I have just found out that if I go ahead and disconnect bluetooth and get the connection through USB running, I can then re-enable Bluetooth and they both keep working.
THis is a completely stock S2, so it would be nice if it was possible to change this irritating behaviour.

You've already been given your answer, flash a custom ROM that's deleted and the bloatware, and please don't become one of those newbies that doesn't read the responses in the very thread they started

Yes I have read "TehH4rRy"'s answer. My apology for not thanking him for that.
I was hoping for a solution that does not involve flashing and rooting since i have much better things to do with my time, and I was hoping this was just about me not knowing some perhaps hidden options to turn this behaviour off.
As far as I know this is the generic "Q&A" section, so you can't assume that everybody that posts a question here is looking to flash their S2 to death.
I posted my finding so that if somebody else had the same problem and is not willing to flash their phone, they would know that there is a work-around, and perhaps some other kindly helping users have even better work-arounds.
Your answer on the other hand I am not sure what it adds to the thread... but thanks anyway.

If you enable USB debugging, the phone will not disconnect the Bluetooth.

[Q] Atrix sound issue

Hi, I am using the very wonderful MROM 7.2 on my Atrix and loving it except for one really annoying problem. I have searched the forum and can't seem to find anything similar so I would really appreciate some help please.
Basically, if I put the phone on charge (either dock or USB) the sound switches off completely. A phone that won't ring is not the most useful device!
I have tried;
Rebooting- sometimes helps, sometimes doesn't
Checking the sound on all my apps- made no difference
Rebooting into recovery and reflashing addons- made no difference
Rebooting into recovery and clearing caches- made no difference
Unfortunately, this seems to be the worst sort of problem; it is intermittent and I never know when the phone has done it. Can anyone please advise?
Thanks in advance
have you checked the hmdi audio output option in settings when you don't have sound?
somewhere in settings - advanced i believe

Thanks for the idea. Yes, I had checked that but I think I may have a solution.
In exasperation I slammed it down on the desk and the damned thing started to work! Looking like a hardware fail so I have ordered a new ribbon cable and will see how that goes.
I appreciate you taking the time the answer though.
Cheers!

[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.

I've covered everything like that in about 100 different ways, none of which made any difference.

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!

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] Bluetooth Tethering

This is my second post, put the first in wrong area. so Hi everyone.
I want to use Bluetooth Tethering on my phone to use with a TomTom SatNav/GPS. I can get the two device paired no problem, but need tethering for a feature on the TomTom SatNav/GPS.
Is there any way of getting this with software or Apps, or its not possible on this model phone.
thanks

appradio unchained

I have appradio unchained , gs4 and a pioneer appradio3. I am not completely helpless on a computer but I am far from your levels, so please be patient. I have been at this for about a month, lol and I have it all working except I cannot get the Bluetooth media connection to stay connected. it actually connects and works via Bluetooth but as soon as I hook up my mhl cable it disconnects the media connection through Bluetooth.
I bring this up because even though I have a mirrored image on the hu I cannot use the touch screen and I read somewhere I need the Bluetooth media connection to use the touch screen.
Any idea on how I could get this to work would be appreciated,
Thanks in advance
Any chance im missing some basic settings?

Just thought id add that maybe ive missed some basic setting in my gs4 that allows or disallows having a mhl cable and Bluetooth functioning at the same time? I just cant find any reason why it shuts down only the media side of my Bluetooth when I hook up the mhl cable?
Please let there be help for this!
any idea were else i could post?
Dos anyone here have any idea of another forum I could use to try find some help? I am running out of ideas.

Ok well I have read already and that's were I downloaded appradio unchained. I went over the survey and didn't find anyone with the s4 running4.4.2 that had it working.
Dos anyone think installing a custom rom would fix the issue and if so which one would you recommend?
Anybody think the s5 might help?
