I've seen this issue on a few different Android devices when I did a search but no real solutions and nothing for the N7 specifically. My N7 music playback keeps skipping. This happens whether the screen is off or on, whether it's through headphones or the speaker, whatever. I'm just using the stock Google Music app to play standard MP3s, I have no problem playing these same files on my laptop or my iPhone. If I leave it for about 10 minutes the playback seems to be fine but it's still an irritating issue I shouldn't have to put up with and when I go back to listen to music later on the same thing will happen again. Any idea what it could be? I don't have any CPU power saving apps installed or anything like that so I have no idea.
