When my EVO is charging it freezes as to become almost completely unusable. Finger presses, swipes, etc. are only barely registered, if at all. Multitouch completely doesn't work. The 4 buttons at the bottom rarely work. The problem persists across multiple chargers, even the stock charger, and it doesn't matter whether I'm plugged in to the wall or into my PC via USB. But here's the confusing part: the problem only seems to occur when I plug in at work. I've never experienced the problem when charging at home. Is the voltage in my outlets at work somehow screwed up? Too much/little/inconsistent power? I've only had my EVO for about 25 days, so should I try to exchange it? It would be a pain since I'm already rooted, customized, etc. but it would probably be worth the inconvenience if it would fix the problem. Any ideas???
