Constantly losing Bluetooth when A2DP triggers

I have a Bluetooth headset that supports A2DP. All notifications and media play through it automatically, which I very much like. It worked perfectly on my OG Epic 4G, but on the Touch I've had constant issues where somewhere around 25% of the time that my phone sends it something via A2DP (usually a notification sound) my Bluetooth will disconnect, I'll hear its disconnect sound, then I'll have to wait a couple of seconds to hear it reconnect, which it succeeds at roughly 80% of the time. Otherwise I have to turn it off and back on to get it to connect.
Anyone else experience the same with theirs? Any thoughts on a cause/solution?

Are you rooted? What ROM are you running?

While I am now rooted, but otherwise stock, this problem has occurred since day one. It's not related to any customizations.

Am I REALLY the only one experiencing this? Seems surprising.

No. I thought it was my headset, and I was about to replace it.

All right, so we've got one more person with the same issue. Now if only we had some extra thoughts on a solution, or a line on this being something Samsung is aware of.

Since this got moved I'm not sure if it's been seen in this forum. Anyone got any thoughts? Similar experience? Idea of if there's a possible fix?

I'm have a problem playing bluetooth audio through my factory stereo
I'm have a problem playing bluetooth audio through my factory stereo, which worked flawless with the EVO. This is a show stopper for me because I travel a lot and listen to podcasts in my car. Since I got the E4GT I have been unable to stream BT audio.

I wouldn't be at all surprised to find out this is related to the same SoundPool bug that causes a lot of games to crash on the E4GT. I have no further info to help you, unfortunately; you can Google around about that. The short version is that that if it IS another symptom of that same bug, there's probably no fix.

I have a tiny Bluetooth USB jig that I plug into my laptop and my music plays fine through my laptop. I will test it out over a longer period of time tomorrow but so far its been great..

[Q] Bluetooth Issue when connecting with OEM Car stero

heylo everyone,
experiencing a issue which had become a pain !
i have a ford figo with OEM stero (India) which is an awesome one. i had a SE ARC before i moved to HTC One X and with Arc, once paired, there was absoultely no problem ever to pair it again, all i had to do was to switch the bluetooth on and it used to connect.
with HOX, i have a major issue, the first time, it connected flawlessly, was able to make calls, play music from phone thru bluetooth on the stero system. but then comes the problem! it doesnt work the next time, i tried to delete the pairing on both car and phone but with no joy.. i did a factory reset and it again worked once.. next time, it says its connected, but when i play music, it plays on the phone's speakers, i went to music player settings and tried to select the player as bluetooth but doesnt make any difference... i read couple of people having similar but not same problem, some have crackling issue, some are unable to connect, but this is strange, able to connect but only once.. i havent formatted the phone again for this and its a little cumbersome as all my music is on phone and i always used to use the phone to play music.
any help will be much appericiated

I have the same with an after market Sony.
Really erratic pairing. Always pair's phone but not media.
Have to randomly switch it on and off for a while til I get lucky.

It works the same as my SGS2 on my Infiniti (Nissan) nav system both for phone and media. The One X has BT 4.0 which I'm assuming is backwards compatible but it might be a challenge with some systems/devices.

Barry, Possibly yes, but i beleive new technology is always backward compatible ..
anyone had a fix ? i read about some bluetooth stack fixes, but looks like it was for a previous HTC device and not HOX..

I can fairly pin the issue down to your car audio not playing nice with Bluetooth 4.0. Yes, its backwards compatible, but, that's not always a guarantee. Get some other Bluetooth 4.0 devices to check.

have you tried restarting the phone when this happens? I happens to me now on the HOX and did happen on my old desire. If I restart the phone all connects fine and can phone and listen to music.... although the music stutters. using an aftermarket sony.

This same problem here with after market Sony MEX-BT3800U.
Before I use to have Desire HD, which was fine, now it's a nightmare.
Maybe somebody have more luck with different after market model which works perfectly with HOX ?

Mine is a Sony unit too... Possibly that one off the top of my head. It's annoying as sound quality via aux in is awful due to the low volume

Got the same problem in my Mitsubishi Outlander navigation system.Don't know why.Must be the version of the bluetoot that you'r car isn't recognizing it.You can try to do a factory reset of you'r car stereo,i did that the other day and now seems that it's working well,don't know the reason why.I think that it's the cars fault because the bluetooth headset that i use doesn't seem to have any problems working or connecting to my HTC.Even if you have open "slots" in your car to connect you'r phone,the car doesn't whipe the data of the last phones you used on it,that is why i am saying to do a factory reset.I don't know if you can do it yourself,i went with my car at the Mitsubishi Service,they conected the computer,reseted the navigation system,connected my phone and now works.

I find it ridiculous that a £150 Sony head unit has issues, wheras I have a £20 Nokia cheap bluetooth headset that works flawless, thats a good few years old.

Solved ! Bluetooth Issue when connecting with OEM Car music system
Finally this is solved for me after the 1.28.720.10 Update it now connects flawlessly and works like charm everytime anyone else who had problems tried this ?

Mine works fine with my Ford OEM headunit.

I havent had the update yet so will have to wait for that to try i guess
Mine takes agaes to pair to car BT and then doesnt connect when in range

Same problem here with a Sony head unit.
Phone profile connects flawlessly every time
Media profile seems random (though I have better luck if I leave the head unit on and switch bluetooth off and on again on the phone)
My software version is 1.28.401.9 so I guess I'll sit tight for an update and hope it cures it. I get nothing new if I try to trigger an update, so it's probably a case of waiting for HTC to pull their fingers out

Mine works great with my Sony head unit and am on 1.26.206.2 (o2) I even stream my music flawlessly phone calls work can you not take ur handset back and say its not working and exchange it for another 1

i have a mazda 3 and i have the same issue! i checked the heck out of these forums and havent seen anyone reporting the same issue i have, i was beginning to wonder if it was just me.....
has anyone else had issues with track advancing etc? not just with cars but with other devices like headphones or bt boomboxes? i wonder if the issue persists across devices.
has anyone gotten this to work with the HOX?

I also have weird experiences about the bluetooth-car connection.
On my desire, when i just get in my car, without doing anything else the phone/car would recognize each other and the music on my desire would start playing in the car instantly.
Now on the HOX, phone part always gets connected, no exceptions, media part gets sometimes connected sometimes not, if it gets connected it sometimes starts playing automatically it sometimes does not, and regardless of it plays automatically or not, i sometimes can use the controls on the steering wheel to skip songs and such, but sometimes i cannot.
Any ideas to what is causing these "sometimes"es?

Im on version 1.28.061.9 and mine doesnt connect at all. When pairing it stays on "pairing" for quite a long time and eventually it pairs but then doesnt connect
Tried a second HOX and its the same with that
Hoping that there will be a future update to fix this
This on the OEM bluetooth on a fiat Panda

Gap & silent during listen music

-when listen music either on HTC music widget or PowerAmp
- got Gap and silent when using Bluetooth headset
- works fine if direct connect to the ONE X
any idea and fix ???

I've yet to see if this works for bluetooth but had a look at the ROMeOS rom and saw this in the build.prop as monx seams to have fixed the stutter: lpa.decode=true
I've set this in my build.prop and will try through the car bluetooth tomorrow.
To edit build.prop in the system folder you will need root access

thanks , buddy , let me know the result.

Unfortunately made no difference for me, will keep digging though as this is annoying when I have a 40 min commute to work each morning and again back.
Anyone have any idea's?
Edit: this doesn't just happen on the beats setting, turning it off makes no difference.

Anyone have any ideas on any fixes yet?

Have the same stutter issue even after 1.28 update connected with my bluetooth MW600.
Seems the problem is device switching to power conserve core. When i play music in background while running GPS in foreground, iam not getting the stutter.

I have the same bluetooth headset, the MW600 and the stutter makes it unusable. I'm on 1.29 stock now and I got to the point that I don't use my MW600 for listening to music anymore, but just wired Sennheisers.
Have you found a solution yet?

I was also planning on buying that Sony thing, but then I found my Nokia BH 214 back. It is now charging and when I'm back home I will test it. If it also stutters, I'm not going to buy a new headset, because it's likely to have the same problems, although that Sony is Bluetooth 3.0, which could make a difference.
I'll let you know the results with the Nokia.

I have stutter problem with sennheiser Bluetooth headphones. Am on stock 1.28, and disabling beats doesn't help (although did help on older version)

I'm running 1.28 & have the same issue with my car kit which is a works supplied Nokia car kit that allows A2DP connections. I'm definitely going to try running the GPS at the same time on my way home from work to see it that fixes it as suggested. I have a usb charger that I plug in so won't be using any extra juice. I'll post back my results.

Sorry for the very late reply, I completely forgot it. Just yet I tested the Nokia BH 214. First my One X couldn't find it, tried for almost 10 minutes. Then I disabled WiFi, just to try, and yes the headset was found. Then I put WiFi back on, but it refused to communicate. Wifi off again, communicating worked. So to say pairing was easy: far from that.
Now the next phase: listening to music. Completely unusable. Very very bad. There's something wrong with output, vocals are washed away and sound like the singer is 100 miles away. While quality isn't an issue with the MW600. But also the gaps. What is also very strange is when the phone is on my desk in line of sight with my headset, the are only a few gaps. But as soon as I put the phone in my pocket, the gaps increase exponentially.
So I think in my case the only thing left is to send the phone back. There must be something wrong with it, my WiFi reception is also very bad. Bluetooth also sucks, so since WiFi and Bluetooth are handled by the same chip, there must be something wrong with it. I really like the phone and sending it back means it's away for 2/3/? weeks, but first I hoped it was something with the software but that hope is fading away.
--------edit: just pissed of by all this. Called HTC and I'm sending it back for repair. Nice phone, but basics like WiFi and Bluetooth must work and they don't. They said it will be back in 7-10 working days. Hope they can keep that promise. --------

Have the same problem with my Jabra Freeway, really annoying to get thos silent gaps when listening to podcasts and music in the car. Tried to run navigation on my way to work today to see if that made any difference but it didn't :-(

Thanks for info.
Seems the problem is more related to Bluetooth version & buffering.
I'm planning to buy Sony wireless headset pro with bt v3.

Sent from my HTC One X using XDA

I just tried using my Moto S10-HD after reading this, and thought I would tell you my experience. I have alot of music on my phone, and I just hooked up my BT with Wifi on and no issues, so I started to play music and so far 3 songs and no gaps stutter or anything like that. One thing that does happen which prior phones didnt happen is that when the screen goes to stand by after not touching it, there is a .5 second interruption in the song, but thats it I am currently on my forth song and the phone is in "standby" mode and it plays perfectly.
I have the WWE version of the phone using 1.29.401.11 ROM BL unlocked, rooted, and custom stock rom.

Not sure that it helps you but to share my experience; I have occasional stuttering on bluetooth using my Sennheisers if the phone is in my pocket. I found that I can replicate the stuttering if I completely cover the top of the phone with a hand on either side and cupped together at the top - in fact I can cut off bluetooth playback altogether.
This isn't a normal way of holding the phone obviously - but it does count if the phone is in your pocket, there is already some 'resistance/interference' from the surroundings. Other than that, I have great wifi reception, best of any phone I have had.
Could this be a hardware fault? Maybe they just need to boost the bluetooth signal / improve buffering?
I only got my HOX this week, aside from this issue it is great, no other issues - touch wood

Mine seemed to studder when it was in my pocket while I walked my dog. I sent it in for other issues and we'll see if the new one has similar issues.

Same problem here ! Kinda disapointed !

Same problem SonyEricsson HBH-IS800
I also have a lot of stuttering. It appears to be a very weak signal because it works better (though still not flawless) when I have the phone close to the headset.
Putting the phone in my pocket is already far enough for playback to completely stop working.

Different bluetooth stack?

Hi everyone,
The bluetooth on my GSIII has been a complete failure. You can follow the saga here (http://www.benzworld.org/forums/w245-b-class/1662643-2009-w245-samsung-galaxy-s-iii.html), but basically it connects to my car and has no sound with the stock ROM and refuses to connect to the car at all with the AOKP JB build. It suggests an android problem, so I'm wondering if the bluetooth stack can be reloaded to reflashed with something different. If anyone has any ideas, I'm all ears. Thank you!

I have a problem with one of my Bluetooth devices dropping and reconnecting. Not sure why is just one. It works fine on an iPhone. I'm guessing your GS3 isn't the international version?

Try CM9. Bluetooth works much better with it. CM10 should have it fixed as well in a day or two.

Here's a 'six months later' update. My phone went through various android updates and I'm now on Android 4.1.1 (up from 4.0.4). The problem was still not solved, but instead of no audio, I now have one way audio, where people hear me but I don't hear them through bluetooth. I have also gone through a number of custom ROMs and kernels for my phone (including CM9/10 and AOKP) and nothing helped with the issue.
A couple of days ago, my girlfriend's HTC One X (finally!) got its Android update, also from 4.0.4 to 4.1.1. Her phone now works like a charm with the in-car bluetooth.
The solution I ended up with was a car cradle and a couple of NFC tags to control my phone in the car. My NFC tag that's stuck to my car cradle turns off WiFi, starts car mode, starts a car home app and turns my volume to max. All I have to do after that is connect the 3.5mm audio cable and I use my phone in place of the car's infotainment system. That way the phone integrates into the car as well and the only thing I lose are the steering wheel controls (they still work for volume).
My less technologically inclined girlfriend now has everything work auto-magicallly with bluetooth. So I guess all's well that ends well, but to anyone considering a US-spec Galaxy S III, watch out: the bluetooth issue is still not fixed. If bluetooth is critical, consider the HTC One X (but be warned: it has awful battery life!)

I have no issues with stereo Bluetooth and mono Bluetooth. Everything and everyone hears and plays fine. It might be an issue with your headset.

If you're on stock... just nm then.

What's wrong with stock? I have no major issues with streaming BT from my phone to my Mazda 3 head unit, or to my Sony MW600 earphones. Even track titles work (the only thing that doesn't work is time display). In my experience, Bluetooth works best on the stock ROM.
Stock Rogers ROM (DLK4 - JB 4.1.1), rooted
KT747 (1/9/2013) kernel
CWM Recovery 6.0.2.3
PlayerPro Music Player
On my old Xperia X10, I had CM7 and had no end of issues with BT:
- Sometimes it would connect and there would be no sound
- Sometimes it wouldn't connect at all
- Sometimes it would cut out after switching songs
- It would stutter a lot whenever Wi-Fi was enabled (but I think that was a problem with the Xperia).
When I tried CM10.0 on my S3 I had similar connection issues, just not as bad. Also, the volume gain over BT was much lower, so I had to turn the car speakers way up. Stock 4.1.1 doesn't have any of these problems. The only problem I had was the audio switching over to speaker after turning off the car, but I fixed it.
Also, BT is apparently broken in 4.2.1 in general, not just CM10.1. Google confirmed a BT patch that works on the Nexus 7, due for release with 4.2.2: http://www.expertreviews.co.uk/smar...confirms-android-4-2-bluetooth-streaming-flaw
TIP: Don't forget to turn up the volume on your phone. I don't know how many times I accidentally turned down the volume and thought that it wasn't working. Now I have Tasker do it for me whenever I connect. :good:

4.1.2 has Bluetooth working use it everyday. (Stock and ROM.) Can't tell u which combo I use at a time. I flash a different ROM everyday. As 4.2.1bluetooth is broken expect for task's AOKP. He has it workingish.
Now as connecting to a car. Depends on what it connects as. And I've learned going to and from ROMs when u connect a source hit the volume up 9/10 times it works

[Q] Jelly Bean Car Bluetooth connection

I didn't see any other threads on this and I'm not sure if it might be specific to the Verizon Galaxy Nexus or Lexus/Toyota cars. Since Jelly Bean, I've already had my car's bluetooth connectivity go into a weird state with the phone three times.
The car will be playing music (default music app) and the navigation app, playing just fine through the car's bluetooth, and then, both the car and phone will indicate connected, but the sound will stop. If I turn off the car, the bluetooth on the phone thinks its still connected. The only way to clear the condition is to turn off the bluetooth on the phone and turn it back on. So much for that "extra" Verizon testing. This all worked fine for me with ICS.
Anyone else see a problem like this?
Thanks!

I am having occasional problems connecting since jb. Was rock solid on ics. I am on sprint and have a Lexus.
This is my only issue with 4.1.

Samsung Galaxy S3 running Omega JB 4.1.1 - Driving a Toyota Prius
Greetings
I myself have experienced odd bluetooth issues with my Samsung Galaxy S3 running Omega JB 4.1.1 version 30 whilst driving my Toyota Prius.
Every 5 mins or 10 mins or so many minutes the audio from my podcast, for example, stops dead and I have to open up the app and hit play for it to continue.
Bizarrely I also experienced this the other day whilst driving a VW too.
Was fine on ICS.
I've you to find a solution.
I've been using Omega since version 25 and have also experienced the same issue on the Wannam custom stock rom.
Tonight I placed the device into Aeroplane mode and kept bluetooth running and the problem persisted.
I have no idea with regards I'm afraid.
Thanks
Dave
Update: I found that the audio issue I was experiencing was not bluetooth specific. I tried direct in to the car audio via the AUX jack and the problem persisted. But I also noted that after a clean install of a rom the issue did not exist so I worked my way towards the removal of the Deezer app and since then I have not experienced the problem. Go figure?

I am not having this problem with my Nexus and my myford touch sync setup. I do, however, get a lag between video and sound, where the sound is behind of the picture and out of sync. *shrug* Wish I could help more.

I can't even do more than phone on my 2012 BMW. No mobile office but calls work fine. When the CSR is turned off it doesn't switch to headset like it will of my wife's 2004 lancer.
