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?

does this problem occur when you are in safe mode?

since you recently upgraded you can try to software repair using Xperia Companion

Hi @le-franck,

Welcome to the forum!

Does this happen no matter what device you are connected to? Be that a speaker, headset and so on. If so, as previously mentioned in this thread, have you tried rebooting your phone to safe mode in order to find out if a third party application might be behind this.

Is there a pattern as to when Bluetooth turns off? For example if it turns off after a specific action is performed.

same here, the bluetooth on my Z5 premium's bluetooth will off by itself, when i tried to turn it on, it will auto slide back to off.

Hi!

Thanks for your reply and sorry about the delay... I've tried in my car (bluetooth adapter). It always worked great before the update, as well as with other phones, but on my way back from work (just after updating my phone) it started regularly deconnecting and reconnecting for no reason. I was just using Google maps. I tried at work with my (Sony) bluetooth headphones, which used to work great too, but same problem, even after restarting. Will try again in safe mode.

I'm also experiencing a lot of instability and random disconnections with this update.@Didrik please see my post here: /t5/Android-development/Latest-Xperia-System-Update-Version-32-2-A-253-broke-Bluetooth/m-p/1144363#U...

How can i revert this update?

[le-franck]

Just tried in safe mode, and it doesn't seem to disconnect anymore. Also I tried in normal mode, and as I hadn't turned my phone on for a couple of days, I got lots of notifications from different apps, during which the bluetooth disconnected several times. It was more stable once notifications stopped coming in, but it still disconnected every few minutes.

@le-franck, if I understood correctly then the Bluetooth does still disconnect but not as often? Did it happen at all while in safe mode? If not then this might be related to an app that you have installed in your phone. It's hard to say exactly which one so you may have to play the guessing game unfortunately. My suggestion would be that you start by installing all available updates, if that does not help then you might have to uninstall your downloaded apps.

Hi,

so, no it didn't happen less often, but it happened more often while I was getting notifications after starting my phone. It didn't happen at all in safe mode. I didn't install any new app after the update and didn't do anything that I wasn't already doing before the update, so I don't see how that can be the problem. On top of that, I've bought a new, much cheaper phone a couple of days ago, installed exactly the same apps and configured it the same way, and I have absolutely no problem with bluetooth, or anything else. The phone even seems more responsive, even though, if you look at the specs, it really shouldn't. I've tried complete reinstalls on my Sony but the basic system and default apps use a lot of RAM straight from the first start (both phones have 2GB RAM), and I need to restart my Sony every few days because it becomes too slow (RAM completely full). This was definitely linked to the hacky music over bluetooth (it didn't happen for a while after restarting). Now with the constant disconnections, it's a bit much for me.

So, thanks for your replies, nothing personal, I know you're trying to help people here, but I'm done with Sony.

I'm sorry to hear you feel that way @le-franck.

My guess about this is that it's hardware related if you've tried all the suggestions in this thread, in order to have your device sent to and examined by an authorized service center contact your Local support.
