Since android 11 update when listening to any music app, Poweramp, Spotify, etc via phone speaker, the music will start glitching immediately when the app screen is switched or display turned off. Battery optimization and power saving are turned off. Not replicated when headset plugged in. Listening via speaker requires app screen to be permanently displayed.
Hi, thanks for your reply. Don't think so, it was bought in MVideo, Moscow, Russia. Wanted to try wiping cache partition, but it simply refuses to boot into recovery mode.
