Have had my Sensation for 1 week and it's started to exibit really strange behavior. The unlock ring doesn't always respond to my touch it sometimres takes 2 or 4 tries to unlock the screen. Also, the number dial pad is somtimes slow to respond or doesn't respond to the first touch. The spinning 3d screens also don't work all the time, somtimes it just opens apps rather than spinning. It's really inconsistent doesn't happen all the time but when it does it's really a problem. From the reasearch I've done it seems like it's a common problem with alot of people after they have owned the phone a week or so. I don't see any posts here about it though? I'm cosidering returning the phone before my 2 weeks is up.
