Bluetooth keeps turning off after upgrade to 32.2.A.0.253

[le-franck]

Hi,

so I've got a Z5 compact, and the bluetooth sounds was very often stuttering, no matter what device it was connected to (car, BT headhphones, BT speakers, ...). Since the upgrade to 32.2.A.0.253, the problem seems to be gone, but now bluetooth often (every few minutes) turns itself off, and then back on. Sometimes I have to turn it on again myself.

Anyone else has that problem? Will that phone ever work the way it should?

Same problem here. I'm on MM build 32.2.A.0.305, Z5 Premium. At least once a day the bluetooth on the phone will crash, turn itself off and won't turn on again. The only resolution is to restart the phone.

I have a Huawei watch and I've had to disable bluetooth audio on the watch as this keeps a 'hard' bluetooth connection to the phone, which was making phone bluetooth crash several times an hour. Now the 'soft' connection is just unreliable - you try to use google voice, or any watch commands and they fail 50% of the time as the watch isn't actually connected to the phone.

The issues are worse when multiple devices are connected. I took a 90 minute drive last night streaming music from my phone to my car bluetooth and the phone bluetooth crashed 3 times, requiring a reboot each time.

I've tried all the advice here and in the many other forum posts on bluetooth issues:

- Software repair

- adb shell pm hide com.sonymobile.playanywhere

- wipe cache and data from android wear, google play services etc

- delete bluetooth devices and re-pair

etc.

Nothing has fixed the issues - they just change the characteristics for a while. Every Sony update changes the behaviour slightly, but nothing fixes it.

My daughter has just bought an Xperia X Compact and is having exactly the same issues. There is clearly a serious problem with the bluetooth implementation on the recent Xperia phones, as evidenced by the large volume of bluetooth forum posts here and elsewhere.

I'm a long time Sony fan (X10 mini, Xperia S, Xperia Z2, Z5 Premium) but this will be my lasy Sony phone. I'm fed up with poor customer service, poor quality assurance and slow / non-existent fixes. I just wish I could get rid of this Z5 Premium before my contract is up in 18 months time and get a phone that works.

Try Disabling Mirror Link Service.

I had problems where mirror link would activate Bluetooth when the master switch for Bluetooth was off, and then activating Bluetooth via master switch would cause a device in use error because of the phantom Bluetooth device created by Mirror Link

Mirror Link can't be disabled unfortunately. Well I had the exact same issue which resolved when I uninstalled Android Wear and Google Fit to make sure. Looks like we can't blame Sony on this one. We can't expect them to release a new update for a flaw in an app. Google need to update their apps to be compatible with our new software , it's as simple as that. We should be raising this case with Google in my opinion, and not Sony.

Don't need to disable. You can use a 3rd party app to kill the process. You might even be able to do it in Developer mode. I haven't tried that option though, so I'm not 100% sure if there's a process killer in there.

I've updated to 7.0 Nougat today and so far so good.
I uninstalled Android Wear when I was on 6.0.1 waiting for either Sony or Google to sort it out as it was driving me mad having to restart my phone literally everytime I required Bluetooth throughout the day (around 7 times).
So I updated OTA this morning then I installed Android Wear afterwards and tapped "forgot my watch" in the Android Wear App. Then I unpaired and factory reset my watch and paired it as fresh. No problems for 8 hours and counting, but as with all technical problems I'll give it a week and report back here to confirm.

P. S. Nougat 7.0 is quite impressive! It's a very smooth OS. Can't say the signature Sony delay was worth it though.

24 hours now, not a single problem

[markade163]

Sorry I composed but didn't post the message so that makes it 48 hours of stability.

Looks like the problem has been resolved

Can anyone else confirm that the software update to 7.0 has fixed the problem for them?

This solution (deinstal Wear, forget watch, factory default watch, install Wear and pair your watch) always works to solve most of the Bluetooth disconnects.

Somebody knows about this firmware version?
