So yeah i got nothing more to say...
My Samsung Galaxy s6 (and previous android phones) have an issue with video and audio playback. Any and all media cuts off a second before it should meaning songs dont crossfade at all and cut sharply and all videos (youtube app, vlc, default video player,etc) does the same. rooted device and has had no effect. this phone is brand new and it has done this since unboxing.
I know others have this issue but its hard to find answers online since other issues related to audio always come up but not THIS issue.
