[Q] Bluetooth microphone cuts out after a few minutes during phonecall - Galaxy S II Q&A, Help & Troubleshooting

What i have:
Stock android 4.0.3 Samsung Galaxy S2 ROM
Rooted
Droidwall
Titanium Backup
No other root using fiddling.
Phone is connected to 2 bluetooth carkits (2 cars) and a bluetooth headset
What happens:
On all 3 bluetooth devices;
I call, and have a fun conversation. After a while (moment changes, anywhere from 3 to 16 minutes i have noticed) the microphone suddenly stops working. The other side can't hear me at all and only switching to speaker or turning off the headset makes me able to continue.
What i did already
Reflashed the phone after a factory reset.
Did not fiddle with the service mode
Installed various volume tools and uninstalled them.
The questions:
Am i the only one? I have seen tons of microphone issues, but none like this.
Does anyone know how to fix this?

MW600 connection problems

Hi,
A couple of weeks ago, MW600 was working as expected. But at the moment, I've got connection problems. Is anyone experiencing anything similar, or do you have any tips?
I have tried restarting both the phone and the MW. The radio function works perfectly. I have tried renaming my phone.
Here's what I'm doing:
* Turn on MW
* Turn on bluetooth on phone
* Search for units -> pair the two units using code 0000 (starting from scratch, just in case)
* Phone states that MW is connected to phone and media sound
* If mediascape is playing, I hear ~1 second of media sound
* After 1-3 seconds, MW makes a sound (5 descending tones) -> the phone briefly states that MW is connected to media sound only -> the phone goes back to stating that the two units are paired (no connection)
What do you think?
Mine doesn't do that, so it's quite odd.. Do a full reset of the MW600 (manual here: turn off, press and hold down power until pairing indication appears, press power and call buttons simultaneously until headset turns off), delete it form the phone and try again. There's no reason for it to do that.
I found the battery life to be a bit short....10 minutes of streaming music and it shut off, all this after overnight charging.....I have repeat this 'issue' Friday night, Saturday and Sunday only to have MW600 dead at the office now
My runs 12-15 hours! Without any Problems.
Same, I can use mine for at least 4 days (about one and a half hours a day) before it needs recharging - are you using the right charger?

You press the buttons on the MW600 itself, not on the phone. Read the manual that I linked to, it's all in there.
hmm anyone else have problem with the ringtone playing thru the mw600? when the phone rings. i can hear it ring on the bt headset. but it's like play a bit.. then i hear a beep.. then it plays a bit more.. and beep it's like intermittent
The beep means, that the headset is changing from the mediamode to the telephonemode.
Update... The problem above came back. If seems related to using bluetooth and wifi simultaneously. Whenever I'm using BT and enable wifi, BT gets a lot of problems and usually shuts down. Does this happen to anyone else?
Also, in the past I could use the buttons on the headset to change songs etc. That doesn't work anymore, even after resetting the headset etc. Is anyone else experiencing this?

Update... Problem keeps coming back. My supplier suggested that BT and wifi might interfere. I'd be very surprised if a "smartphone" cannot play music over bluetooth and surf using wifi at the same time. My supplier promised to check it out and get back to me... That was ~2 weeks ago.
Is ANYONE else experiencing the same problem? Can you listen to music over BT, then enable wifi, connect to a network, and keep listening to music over BT?

I have wifi on 24h/day and most of the time i don't have any problems but sometime they get disconnected and i have to turn off/on BT and everything runs fine after.
I will have to try without wifi
Bluetooth and Wireless LAN (WiFi) both uses the same frequency space (~2.5 GHz)
Most of the times Bluetooth should be smart enough to adjust the frequency to co-exist with WiFi devices.
If your area are crowded with other Bluetooth devices and WiFi access-points, the Bluetooth set might having trouble settle on one quiet frequency, and might just sit there trying to switch frequency all the time, never finding a good frequency to settle on.
To help those poor Bluetooth devices along the way, try to change the WiFi access-points channels to create a free channel where the Bluetooth devices can settle on.
Also check if your WiFi access-points have a "Co-exist with Bluetooth" option, and enable it. It will however reduce the frequency-width and therefore the bandwidth slightly on the WiFi, but Bluetooth devices should work with less interruptions.
Connection problem with s60
Hello!
I have an MW600 as well - using with an s60 symbian nokia (6650 fold).
It works corectly when using in bt mode and listening music from the phone, but it alwways lost connection when turm the handsfree to radio. When listening radio, zthere is no connection, no way to get the calls or answer.
Do somebady have the same problem or somebody know how to solve it?
I did reset on mw600 and paired again, but i have the same problem.
รก
i haven't had any problems with my MW. i always stream music from my pc via wifi to my X10, then to my MW via BT, witch is connected to a Reciver for party.
have you tryed restarting your MW after pairing.
My problem with this headset is that it doesn't:
1) caller name not displayed on incoming calls
2) Music/Mp3 tags not displayed on lcd (using Poweramp)
3) why does the phones itself rings not the headset just some beeps. Embarrassing when phone rings and then answer on headset.
Resetted but not solved any problems.
Wildfire running Wildpuzzle 0.8 with kernel 4.1 overclocked
Ok I m using mw600 stereo bluetooth headset with CM 6.1.3 V4.4 rom for 2 days now. The pairing is easy but the issues that I am facing are;
* phone has crashed/rebooted couple of times while pairing/ unpairing.
* besides first fact, it pairs without any problems and very easily.
* I have used it with mixzing and doubletwist media players. In both cases the music lags and sometimes the lag/pause is about 2-3 seconds long.
* incoming call shows phone number only, no contact name.
* voice dialing works.
* when I m listening to music or not listening to music on incoming call the headset converts to phone mode fine but after the call is finished, the headset doesnt reverts back to media mode that is, the music doesn't plays again and I tried connecting and disconnecting again but only way to make it work again is restart the headset.
* battery is so far ok for the headset. Infact I runned out of my phone battery while I was trapped in underground and listening to music.lol
* even the headset is connected, if I play youtube video, the sound comes from the phone speaker. In order for it to come from headset I have to play some music from using my headset controls and then play the video and then pause the track. This also happens with music app aswell sometimes. Like the headset is connected and if I play the song using my phone, it will play through phone speaker and I have to pause it and play it using my headset controls in order to listen through my headset.
So far its oki but its annoying the laggy music thing. It only occours in music playback, I spoke to my mate on phone for couple of hours using this headset and both ends could listen loud and clear.
i also paired it with my inspiron duo tablet and its working flawlessly....so anyone have any work around of the above mentioned problems? anyone facing the same problems? is it because i am using custom ROM? i am ok with the headset not showing song tags and stuff but music being laggy is not acceptable...because thats what i bought it for!
Any help would be much appreciated?
thanks

Bluetooth and in built car system.

I was wondering if anyone could help with this problem. My SGS II connects with my in built (Ford) car system, its does everything it should apart from that it can not display the call list (in or out). This was also the problem on my SGS on stock roms until I installed CM7 and then the call lists showed up perfectly. Is it the case that Samsung roms are putting the call logs in a different place that cannot be seen by the car system, if so would it be easy to change this or do I have to wait until a CM rom is made for the SGS II.
SGS II as well as SGS has a very gig problems with BT in car on stock ROM. I had SGS before and there was a problems BT constantly drops in AUDI car system. Temporarily it was solved by BT Fix from the market but finaly solved only coming to a custom ROM (all of them solving that). Now Having SGS II It is total disaster in AUDI - first it constantly drops BT connection and even more - if I'm talking by phone during being connecting to BT, connection failed BUT after call finished phone crushed down and it takes 10 second pushing power button to get it back :-( And then in phone all pairings went out! So - do anybody know this case? And waiting for the custom ROM.
I have a Mercedes E-class (new type). No problems at all with the BT. Very quick to connect, and I can control track fw/bw from the steering wheel. No drops. Works with the default music player as well as Spotify. Phonebook transfere is quick.
In terms of functions I also have no any problems but drops and crashes :-(
Ford focus audio bluetooth
Hello,
I have the same issue with the Ford Focus Bluetooth. It plays ans stops all the time. hands-free works great. Did you solve it?
Hello everybody.
the same issue with new Volvo S60. Previously car kit perfectly worked with Nokia E71... As for S2 - I was able to pair the phone and car. But afterwards, connection could be reestablished only if it's initiated from the phone side (I select "My Car" in bluetooth menu of the phone). Without such actions the car is unable to find the device...
Problem was solved for me when last modem was released. Use ROM with XKE2 modem.
Hi all,
Yesterday I have tested SGS2 (LiteROM 1.5) in my BMW E92 LCI and it works really fine so far.
(call, sms, phone adressbook and bluetooth audio streaming).
BMW offers the possibility to connect two phones at the same time.
I successfully connected my nokia business phone for bluetooth call & SGS2 for bluetooth audio streaming only.
SGS2 is the first mobile that I have connected to my car not only displaying title/artist information properly using the default music player,
but also offers good mp3 sound quality over A2DP.
Strange enough, when I use a different music player (e.g. PowerAMP) the title/artist information is not working any longer. Any ideas?
Cheers, Spad
Problem with transmission over car bluetooth
Hi there,
I have a galaxy s2 that used to connect (with no problems) with my alpine CDE-126BT
After I messed around with the service mode for a while trying to crank up the volumes, there is no transmitted voice over the call (the other side can not here me when I'm connected to the car's Bluetooth).
I know that if I reboot the phone all the changes that was done in the service mode would reset to the default settings, it seems to revert back default but I still have the same problem.
Any advice??
Thanks,
David.

[Q] Bluetooth issues

Hi,
I have the following problem:
Everytime I pair my Samsung Galaxy SII I9000 with my car (Renault Fluence 2012) and its built in bluetooth System, it says that it's correctly paired (and honestly it doesnt even take a minute to pair correctly), but it plays no music. It just has no sound (even when the song is playing correctly on the phone) but everything else just works perfect. I mean, i can control the music (songs, playlists, etc) from my car, but the sound just wont come out. The only way to make it work is to 'unlock' the sound by calling someone. So when the call starts, then the audio starts working. That is, so far, the only way to make it work. And i have to do it EVERY SINGLE TIME that i turn on the car or that the device stops being paired with my car.
It does EXACTLY the same thing with my bluetooth headphones (Motorola S305), so I realized it was my phone. I have tried other phones with my car and they work just fine. I have tried other things with my headphones too (like my Psvita) and they work smoothly.
The weird thing about it, is that my phone used to work perfectly fine with both things, and just a random day it decided not to work anymore.
I used kies and re-installed android from 0, and that solved the problem for a few days and then it all started again. I have tried cleaning all the bluetooth devices that my phone is paired with. Going back to factory settings in my car, removing the battery on the phone, resetting the phone, taking everything out (including the sim card( everything. And nothing seems to work.
Please, help!
My phone is a Samsung Galaxy SII with Android 2.3.6 (it came with 2.3.3 and i upgrade it twice through kies) I have never rooted my phone or done anything to it, except for upgrading Android through Kies.
Thanks so much!!!

Wow... That's very strange. First off, I'd be looking at compatibility issues. Do you have the BT specs for the car? Maybe they're the same as the headset and not quite 100% compatible with the phone.
Another possibility (although remote) is that the headset and the car are fighting over which gets to talk to your phone because phone services are much different than A2DP (Audio).
You might just have a flaky BT antenna in your device, or a bad (stock) modem/baseband.
I'd try rooting and see if a different modem/baseband clears up the issue. Then at least you'll know what the deal is.
Hey, I also found this on the Renault web site... http://www.renault.co.uk/bluetooth/default.aspx
>> Why does my telephone not reconnect to the system when the vehicle is started?
- In order for your telephone to automatically connect when the vehicle is started, it may be necessary to activate the automatic Bluetooth connection function on your telephone with the hands-free kit. For details on how to do this, please refer to the instructions manual for your telephone.
- Upon reconnection and if there are several telephones paired within the hands-free kit reception area, it is the one that was paired last that will be connected even if it is outside of the vehicle.
So it looks like it might actually be a Renault AND a Motorola problem.
There's also a list of compatibility files at the bottom of that page based on the system you have.
First of all, thanks so much for your help.
The problem with whats going on with my phone, is that it used to work just fine before, with those 2 things (my car and my headphones) Its not like they never worked, they used to work completely fine with my phone.
And i never use them together, like my headphones have never even come close to my car. And since i thought that it could have been a problem with they 'fighting' with each other, even if they werent close, i erased all the cache on my bluetooth settings and unpaired all devices that were ever set with my phone.
So its like if i had never used bluetooth. That obviously didnt work either
It turns out that your car likely keeps up to 5 phones in memory... Is there a way to clear the phone list in the car as well? Then re-pair from scratch on both sides?
well either the blueth is defect or ur doing some wrong settings,root ur device there r plenty of bt apps tht work more powerfull than the default...y possible ur car mus hav a reset buttun for bt so delete all pairs frm phone an reset ur car bt,,,,then start fresh.....hope it helps
I restored my car's settings and deleted every phone paired. That didnt work either... I also tried with a friends phone (iphone 4) and that worked completely fine...

Time for a warranty replacement I think.
Jeez... thats exactly what i was trying to avoid, because my cellphone company will have me waiting for like a month without my phone and will give me in return the ****tiest phone ever while they try to fix it and then realize they cant.

thanks anyway for your help!

[Q] Blutooth issue in all 4.2.x and above ROMs

Hi, noticed with ALL AOSP / AOKP ROM's 4.2 and above that Bluetooth has an issue, bothering everyday use and still not fixed. Once you use BT car hands free and you want to to take the call back on the handset (internal or external speaker does not make any difference) the sound never comes back to the phone. Tried at least 3 different CM10 and above based ROM's, all has this problem. Anyone can get it fixed? For everyday use this is a real issue, cannot be that you cannot leave your car until you finished the call /or need to close the call and call again with BT off. Not realistic during a daily use. Thanks for any comments
i am having the same problem.
also when calling can't turn off my car. then it quit my call

I was very happy with LiquidSmooth 2.8, so I decided to upgrade to 2.9.
Everything works very well, except for bluetooth.
Symptoms:
- A2DP streaming to my car stereo (JVC x250BT) works
- Bluetooth calls with car stereo result in either no or horrible sound
- Bluetooth calls with my (Parrot ck3100) carkit work sometimes on the first call after a reboot (usually fails)
- Bluetooth calls with a JabraBT215 headset also fail
- All the above has been tested with the device being the only registered (and therefore connected) device.
-- sometimes, I can hear the sound rapidly switching between the handset and the bluetooth device.
Occasionally, I also got no incoming sound during calls with no Bluetooth device connected.
Sometimes, connecting a wired headset would help.
I tried to highlight the point few months ago already on a development forum but I am too junior to be listen to... Even i strongly believe this is a real bug gating real everyday usage if you sometime want to use your phone as a phone..

Question Dialler issues after Android 13 Upgrade

Hey all, I'm wondering if anyone else has had issues with calls after upgrading to Android 13.
I am having 2 problems with calls
1) When I pick up calls on Bluetooth or loudspeaker, often people can't hear me until I switch to holding the phone to my ear, I can then switch back to Bluetooth or loudspeaker, and it works.
2) when I put a call on mute it automatically unmutes after about 20 seconds even though it still shows the mute button as turned on.
These issues happen on multiple different diallers, so they are clearly a phone problem and not to do with a specific dialler app.
Same here. Let's wait for an update. Temporaly I using a wired headset.
