The standby screen (displays time and date during standby) does not recognize a touch of the screen to allow a call to be answered (sliding green unlock to the right or sliding red to left to hang up call) about every 3rd or 4th time, annoying as hell since the phone locks up and I have to remove battery and do a reboot. any answsers?

though at first it was by call blocker app but removed that and it still does it.
