Yeah, another thing is when I'm talking on it with someone for awhile and try to get back to the "call screen" which doesn't happen, and they are still on the phone (if I want to open a browser or do something while I talk on the phone). The screen never comes back though until I either press power or the other party hangs up.

That part is the most frustrating, although someone might reply to this saying that this actually doesn't happen.
