I have a new ipod touch 5th gen and installed ios 7- when I try to swipe up to access command center it is often non-responsive. It usually will take 2-5 swipes (sometimes it just takes one but it has taken as many as 22!). I have tried a reset (by shutting off and from settings) and a restore with no resolution. I assume this is neither normal nor common- is it? There isn't an apple store nearby so I am thinking about returning to amazon for exchange. Is that what you would do or any other suggestions? Thanks.
