Welcome to Android Central! This usually appears on devices that don't have a proximity sensor (which would be needed to detect when the device is up against your ear, and therefore put the screen to sleep while you're talking on the phone, thus preventing accidental screen touches). When there's no proximity sensor, the device will instead lock the screen during the call (again to protect against accidental touches), and require you to double-tap it in order to unlock it. I don't think you can get rid of that.
