I've had my G2 for a couple of months now. Two things are now bugging me. In multiple strong LTE areas my phone drops to a 3G signal and will only pick up LTE again by toggling airplane mode on and off. I'm aware this is probably a network issue but it drives me nuts. This past week my knock on would stop working randomly or so I thought. Knock off works fine but knock on was touch and go. I finely narrowed it down. Turns out it only stops working when the phone is warm. Either from use or in my pocket for a period of time. Once it cools down it works fine. It's not like it's overheating badly either, just warm. Anyone else have these issues?
