When making a call, instead of showing the person's number/icon, the screen goes blank. Not a White or black screen, it's like the wallpaper from another theme. Just after pressing the green button, on top of this dark blue screen, I get the call 'forwarding enabled' message, the call connects but the screen remains dark blue until I close the call. A small but annoying problem... Any ideas?

i had the same problem with mine one, exactly same issues, but i've soved the problem pulling out the battery for 30 sec, and after that everything worked just fine.give it a shot.
