Music stops playing with Power Saving mode on
Concept has been changed according to the Pie OS concept. If the music application is set to the app sleep mode or the app's background activity is restricted, it will stop after 1 minute after switching to the background.
This concept applies equally to ‘Voice recorder’ and ‘FM radio’. There are 2 ways to remove the restriction of background activity.
Option 1: Launch Settings app > Apps > Select application what you want to remove restriction > tap Battery > Enable Allow background activity.
Option 2: Launch Device care app and tap Battery > tap Settings > tap Sleeping apps > Tap Remove > Select app and tap Remove.
