Hi, Received my new iPhone 5 last Friday. The problem I'm having only happens in the morning and only while still plugged into the wall. If I try to use the phone after 6+ hours (have not tested the actual time) of inactivity, the touchscreen is either barely responsive or not responsive at all. As soon as I unplug the phone from the wall, all problems are gone! I'd be OK living with it but when alarm goes off, I can't stop it and that's a problem... Obviously I can't take it to Apple since I can't replicate the problem unless the phone sits there untouched for several hours... Anyone else having this issue?
