[Problem] Bluetooth carkit issue on Xperia T with stock 4.1.2

Hi All,
I'm experiencing bluetooth car-kit problems after updating from 4.0.4 to 4.1.2. (rooted rom of TiMiN8R)
The problem is when my Xperia T is connected to my BMW it will quit working after a random time, like in 5 to 10 minutes even when I'm not calling or doing anything with my phone.
When looking to my board computer it seems to be that the system keeps syncing my contacts list even when it's already loaded.
Is anyone else experiencing this? Is there a way to fix this and not having to return to 4.0.4?
I found a threat here where they fixed the bluetooth.apk (http://forum.xda-developers.com/showthread.php?t=1896171) but this is for the 4.1.1.
Is anyone able to fix this for the 4.1.2?
Greetings YcKe

I too am having issues with my bluetooth on my VW after going to 4.1.2, but mine works OK, but the display on the car now shows "UNKNOWN" where before it showed the Artist and Song.
Anyone having this issue on 4.1.2 ?

There is another topic with these problems.
Mine is doing the same, volume is back to normal after pairing only if i'm lowering the alarm volume and after that revert to max.

Does your display on the car now shows "UNKNOWN" too ?

This MOD will work for any Jelly Bean ROM for Galaxy SL.
Nop, Xperia T is appearing on my car audio.

Hi all,
Did some experimenting and it seems to work when I deny access to the request to access my contacts.
It also seems that my contacts will eventually be loaded so no access was actually required.
Hope this helps for some as temporary fix.

I get this in my car too, did you get anywhere with it?

No I didn't find any solution for this issue.
But I saw that there was a new firmware released 9.1.A.0.492.
Did anyone try this new version to see if it fixed the issue?

[Q] WiFi and Bluetooth problem connection

Hello guys
Recently I noticed WiFi disconnects when turning Bluetooth on. Whn I opened the WiFi menu all acces points were not available. But when Bluetooth is off there is no problem. Any solutions?

I have the same problem. I'm running CM11 M11 but had the issue also with M10. It is really annoying since I also have a Sony SmartBand and therefore i can't use wifi at all.

same problem here. Seems that bluetooth low enegy device and wifi does not work well together.
I have a xiaomi mi band and it kills wifi as soon as I connect it. The only way around is to disable sync and manually sync. After sync you can go to bluetooth settings and search for devices. After that wifi connects normally until I sync the band to the phone again.

I tried the fix described by @MrSteve555 in the FXP CM11 development thread but it did not help, the issue still remains.

Same thing here. I'm running CM11 M11, Williams v4. A bit annoying if you rely on Bluetooth for the SmartBand. I've taken to having BT on all the time when I'm not at home (not using WiFi) and switching to WiFi with only occasionally turning on BT when I'm home. Not really a solution, but as a workaround it's okay.

I really hope someone can work this out. I think I will just create a tasker profile or something. But then again, not an elegant solution.

I have the same problem, I have it on stock 4.3 rom and now i just installed CM11 and there is still problem. Anyone found a solution? Do I really need to go back to android 4.1 to fix this?

Well I suggest flashing the stock ROM again on your phone. That may solve the problem..

AOSP Bluetooth help

Hey all,
I'm desperate for some help. I recently decided to ditch Sense 5.5 and go to AOSP. I installed CM11 stable, with a clean flash. Everything was great except the Bluetooth. I was able to pair the device to the car, but once paired, it would work for about 15 seconds then force close. I looked a little on the forums, and I found some similar issues, which stated to turn the wifi off while using the Bluetooth. Alas, this did not work for me. I then installed, Liquidsmooth (clean flash), which, unfortunately, had the same issue. I am out of ideas. Can someone please help? I'm running S OFF, if that makes a difference.
Thanks in advance.

MMB29K Bluetooth issues

Hi all, Since I upgraded my stock unrooted Verizon N6, my Bluetooth does not pair with any device at all. Does anyone else have this issue? I searched for a similar thread, but could not find one, so my apologies if this is duplicative. Any help is appreciated.

will try now with my anker bluetooth speaker..
im on stock mmb29k...
il let you know if i have the issue
edit
mine paired

What do you mean by upgraded? OTA update, or did you flash a rom? The only issue I've ever had is Bluetooth disconnecting/ reconnecting. Has become an alarm saying I should reboot, lol. Works fine afterwards.

It was an OTA update. Cannot pair with any Bluetooth device.

I noticed my Plantronics Legend connecting/disconnecting a lot yesterday and a reboot fixed it too. Sounds like that is a good gauge.

So I went to the Google Forums page, wiped cache. Didn't work. Factory reset the device and did not restore previous settings. Treated it as a new phone setup. Problem solved. It appears as though a 3rd party app conflicts with the Bluetooth. I've been kind of picky which apps I reinstalled, so so far, so good.

Bluetooth disconnect randomly

Hello,
Since 1 month, my bluetooth disconnects from my car, BT speaker and BT headset randomly. My Z3C is working with Marshmallow sony rom (last update, no custom rom).
I have tried a factory reset, 2 times, and it works for 1 or 2 days then, BT problem comes back. So, I don't think it is a hardware issue.
What can I do to solve this problem ? I can't stand it anymore !!!
Thanks for your help !

OMG, I can't find help anywhere and I have the same problem. My Pebble Time smartwatch disconnects all the time.

Hello,
I have reset factory my phone and now, I am installing appplications one by one until the phone starts to have BT disconnected. So far so good, I have 80% of all my applications installed and BT still works perfectly. The problem come from an application which disconnect BT. Try to do this. If your BT do not disconnect when the phone have only stock applications, the problem come from an application you have installed. If not, I think it is a hardware problem.

Hello
I have exactly the same problem on Z5C with stock firmware. If you find what app is causing this problem can you tell me please? I don't have this problem on Z3C (SlimRom 3.1) with same apps...

Yes of course. As soon as I found the app, I will post its name. Otherwise, a friend told me that you can install an application which can tells you the permissions of all your apps included access to bluetooth. It can be a lead to the app. Then uninstall apps using BT and test the BT connection. I don't know its name but a quick search on the app market and you will find your happines

Hello,
Did you find something?
Thanks

Not yet. I have several apps remaining to install on the phone. But I won't install several apps again because I don't need them anymore. So it is possible that I never find the wrong app.
Try to use "Permission Friendly Apps" (https://play.google.com/store/apps/details?id=org.androidsoft.app.permission) to search apps which use bluetooth and uninstall them to see if your BT starts to work fine.

I HAVE FOUND IT !!!! The app is called Marmiton. I have just look to its permissions and it take BT properties !!!! After installing it, BT starts to disconnect. Deleting it solve the problem !!

Thanks !!!! It's strange because it's installed on my Z3c and I have no problem. I will check on the Z5c... In my side I thought it was "wear mini launcher" for Android wear.

Thank you Gillou! You saved me. I was going to throw away my xperia z3 which drove me crazy for a year with this BT issue.
I uninstalled Marmiton and everything is fine now .
I can't imagine that a cooking app can bring so many troubles....
