For some reason, the screen on my iPod touch doesn't respond sometimes. For example, when I try to scroll through my music, once in a while it will stop responding and all of a sudden it starts to twitch and it randomly selects a song from my playlist even though I didn't click on them. I restored my iPod touch 5 times and it didn't fix the problem at all. I encountered this problem a couple months back but now it seems to happen every time I use it. Is there any way to fix this?
