Android OS 9.0 Pie FAQ (Hong-Kong version)

Last Update date : Sep 28. 2020

When I Enter Power Saving mode, Music Stops after a Short Time. Why?

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.
