Hi Davy,
I've been using UAPP for some time now on my LG V10, but recently I'm having problems with volume. When I start up the app, it plays fine (am usually using bit perfect mode), but if I pause the music and then play again a little bit later, the volume jumps to max and it is deafening. This also occurs if I pause the music, switch apps to do some thing else (like playing a game) and when I return back to playing music on UAPP, the music is once again at max volume. This has only been happening in probably the 3-4 most recent updates (can't recall how many exactly), but definitely in the past 2-3 months. I have not changed any settings within the app of late, except to toggle off bit perfect mode when I want to use the Morphit functionality. Is there a way to fix this, as I'm afraid to use the app for fear of losing my hearing!!!
