topic Bluetooth stops working in XZ Series

Bluetooth stops working

PeterWallman — Fri, 19 Jan 2018 05:13:04 GMT

Tha last couple of weeks I have noticed that my Xperia XZ Premiums Bluetooth driver stops working. The symptoms is that nothing can pair with the phone and if I try to turn off and on Bluetooth it doesn't work. When I slide the button to position "on" in Bluetooth settings it just turns grey and if I refresh the page it's back on "off".

I can solve the problem with a restart but now the problem is every day and sometimes two times per day.

My Bluetooth behavior has changed a bit since I always have Bluetooth on for syncing with training watch from Garmin. I also use a headset from Jabra several times a day.

Hi !

I have the same problem here, but with Polar systems. (Worked perfectly with 7.1)

Same issues here, for some reason bluetooth stops working after some time (usually each 1-2 days), and cannot be turned on. Only restarting the phone will allow the bluetooth to be turned on. Extremely annoying.

Same problem here!

I use Bluetooth headset in work, in-car Bluetooth and I use a Mk Bradshaw SmartWatch daily, all of which randomly disconnect on a daily basis.

It keeps requiring device restart as the Bluetooth on/off button is unresponsive. I'm looking for trouble shooting information but can't find any.

I have also tried force stopping Bluetooth through application management in settings but not helping either...

I think it's since the Android Oreo update...

@MXperia try going to Settings > System > About phone, and tapping Build number 7 times, then going to Settings > System > Developer options > Bluetooth AVRCP Version and changing it to 1.5 or 1.4, and see if it fixes the connection with your car and watch.

Same here.

All my xperia phones periodically lose connection to paired devices. And only resume it after rebooting or enabling/disabling airplane mode..........

@najodleglejszy: I followed your instructions and have now tried both 1.4 and 1.5. Despite that 1.4 is marked as default I experienced the same problem there. Now I have tried 1.5 for a couple of days and that seems to work.

How do we get this solved "for real" and not just using this workaround? Can your register some bug for future releases?

I did, tested all of them. Same problem.

I agree. When I used 1.4 or 1.5 the problem was less frequent but after some day it came back.

Recieved a android update yesterday from Sony so now I'm testing with 1.6 again.

Exactly the same problem here. Loses connectivity daily and sometimes more often. Means constantly having to restart the phone. Extremely frustrating.
