I'm unable to answer phone calls!!!

[hyun1120]

I've had my EVO for about a week, and today this problem happened to me twice.

Basically, when I take the phone out of my pocket to answer an incoming call, my screen does not respond. I am not able to slide the bar down to answer the call.
Screen responds after I user the power button to put it to sleep and back up.

It's not a huge problem as it only happened twice, however if other users have the same issue, they should fix it.

I am returning this one and getting a white one, but just wanted to find out if anyone else here had the same problem.

I am running latest update / NOT rooted.
