Xperia ZX1 (Oreo 8.0.0/Poweramp 789)
Hello !
When I receive a notification (SMS or e-mail), the music stops on the audio headset and go on the loudspeaker of the telephone (the lapse of time of the notification) then returns on the audio headset! Very annoying problem! I am obliged to put the telephone in mode not to disturb " to by-pass this bug! Cordially Zen
ps. Sorry for my Bad english !
