My new iPhone 5s keeps freezing and restarting, how do I fix the problem?
I bought an iPhone 5s yesterday, everything was working fine, until it started freezing on me. It doesn't just take a moment to unfreeze, but instead makes the screen go dim, and then stays about 3 minutes frozen with a dim, until it shuts off. It stays off for about a minute, and then turns on again. (it restarts) It happens about every 10-20 minutes if I'm on the phone. When I don't touch it, it only restarts every 30-45 minutes. It happens more frequently while on 3G. I've brought it back to where I got it, and they told that they couldn't do anything because it wasn't acting up while they had it. They reset it, and it was working fine for about 30 minutes, until it restarted, I was just playing through my settings. I don't see what I'm doing to make it freeze, and it's very annoying.
