Your mobile phone may be caused by root. You can try to double clear the phone, but everything stored in the phone's memory will be deleted. The operation method is as follows: press and hold the "Volume+button" and "Power button" (also called power button) for 5 seconds at the same time. After the vivo mobile phone Logo appears on the mobile phone, release the button and enter the recovery mode. First, select "Back up User Data" to back up user data. Then Erase Data/Factory Reset Erase All Data/Restore Factory, and then select Restore User Data to restore user data. After the interface jumps, select Restart System Now to restart the phone. If not, you can go to the local after-sales service center for testing and handling. You can check the address of after-sales service center in vivo official website:/service/map.html.
If you have any questions, please feel free to consult us. Thank you very much for your support of our vivo. I wish you a happy life!
