The reasons why the phone suddenly shuts down and restarts on its own are as follows:

1. Check whether the keys of the mobile phone are stuck (such as the keys stuck by objects such as the protective case), because the power button and the volume down button are pressed and held at the same time for more than 10 seconds, the device will trigger a forced restart.

Instead of placing the phone in front of it, place the battery side down.
