Im having the same problem.  The screen doesnt lock at all.  It only locks spurratically when the dialpad is open during a call every keypress when your actually trying to use the keypad in a call.

It sounds like the proximity sensor is not working on your handsets. When it is next to your face it should sense it and lock the keys.
