What should I do if my vivo phone is automatically turned off or turned on?

1, it is recommended to press and hold the power button for ten seconds to restart the phone forcibly.

2, you can try to double clear the phone, but everything stored in the phone memory will be deleted. The operation method is as follows: press and hold the volume increase button and the power button at the same time when the phone is turned off. After the vivo phone logo appears for 3 to 4 seconds, release the button to enter the recovery mode. First, select Erase Data/Restore Factory Settings, wait for the interface to jump, then select Erase Cache Partition, and then select Restart the system immediately to restart the phone immediately. This operation will lose all data on your phone.

3. If it doesn't work, you can go to the local after-sales service center for testing and processing. The address and telephone number of the after-sales service center can be found on the homepage of vivo official website-Services-Network.
