when placing a call, the phone vibrates briefly and the inner display turns off. have to press the ok button to bring display back. what can be done to keep the inner display from turning off. thanks

Hello. I have the same problem too. When I call out, and someone answers, I get the vibration. I have the LG C440 fliphone. How do I get this in standby mode.

Press and hold '#' key when in standby mode to deactivate vibrate mode.
