Poweramp version: 18.104.22.1682, Device: LG G2 Mini (D620r), Android: 5.0.2 (original ROM from Polish T-Mobile). My problem with Poweramp is as follows. When I want to switch to the next / previous track I always have to expect from a second to even 10 seconds to track changed to another (delay between the time you press a button on the screen to respond to the music player). It's the same with pausing the song and its resumption. The problem with Poweramp I have from the very beginning on this phone (previously Android 4.4). The SD card was previously used another phone with an older Android and there were no problems with Poweramp. It is very frustrating, because to switch to the next track you have a long wait, especially if several songs in a row I want to suppress. I would add that in the default Music app has no problem with switching the songs, but to me this application really is not like it, therefore, a long time ago I bought and I do it (now I'm trying despite the problems) Poweramp for listening to music.
