回答“Why won't my HTC One Mini 2 vibrate?”There is a good chance that the tumbler motor is not working. Or there is also the possibility that your settings are no longer synced with the phone.
回答“Why won't my screen light up?”The inside LCD connection for the screen may have come loose or is possibly disconnected. This could have been caused by possible dropping of the phone, or water damage. Therefore the screen would not be lighting up.
