Sony Xperia Pro-1 (XQ-BE52): Bluetooth issue, since system is upgraded to Android 13

[Andre_]

Hello,

I believe, since I have upgraded the phone to Android 13 (so already for a long time) , after some time with several devices that have been connected/disconnected to the phone (sound has been "routed/switched" to the bluetooth device) the phone "stays" beeing "switched" to play the sound via bluetooth, although there is no bluetooth device connected or bluetooth has been turned off at all.

One remark: when pressing the volume button up or down, I can see the music note sign together with the bluetooth sign. Although no bluetooth device is connected or I even have turned off bluetooth.

This is annoying because the phone will not ring or make any accoustic signal in case of a call or message.

Currently the only workaround is to reboot the device.

Am I'm the only one?

Best regards

André
