Some users may have started the update without noticing).

While waiting, it is recommended that you connect the original charger and pay attention to the status of your phone if it is hot.

If you are unable to enter the system seriously or for a long time, please unplug the adapter in time.

And go to the after-sales inspection and processing.

If it is not a cyclic restart and other problems that occur after the system update, you can try to press and hold the Power + Volume Down button to try to enter REC and select Safe Mode.

If the device can be turned on normally in safe mode, press and hold the power button in safe mode to try to restart.

If it's a new phone, it may also be a short circuit in the phone's motherboard.

After the phone is turned off, the battery will run out, which means that your phone has been used for too long, and the battery is almost out of order, and you can go to the store to change the battery.
