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. When the vivo mobile phone Logo appears on your mobile phone, release the button and enter the recovery mode. First, select "Back up User Data" to back up user data. Then erase data /factoryreset clears all data/restores user data after leaving the factory. After the interface jumps, select Restart System Now to restart the phone.
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!
