Everything sames to work aside of one thing, in some applications the volume slider bar that shows up when you change volume is getting stuck/frozen. So basically when I press volume + or - while being on the homescreen, then everything works as expected, the volume bar shows up, there's the volume beep, the slider moves, and I can also slide it by hand. When I try the same within some apps (for example a game or radio app) then the volume does actually change but the volume slider pops up and doesn't move, the volume beep is also missing or just 1 time there. When I try to slide it by hand, it doesn't work, tho I can see that it blinks each time I touch it (touch animation). So any ideas? I've try'd clearing cache and davlink.. maybe I have to clear cache of some services? Or something like that?
