Have any of you encountered the problem where the music skips from time to time even without running other apps and is already in screen lock mode? Another problem is when I also try using the default headset as a controller of my music (double-click to go to the next music) but there's around 30 secs of delay. If I click on the play/pause button (the one at the bottom when the earphone is connected to your ears while the phone is placed lower), there will be 30 secs delay together with random skipping of music? I tried Poweramp as well aside from the default player and encountered the same problem so I uninstalled Poweramp. Any recommendations? Thanks in advance.
