1, press the power button for 30 seconds to see if you can turn on the phone and make it light up.

2. Try the dual-clear mobile phone: press and hold the screen lock key 10 second to restart the mobile phone, and then press and hold the screen lock key and the volume plus key at the same time to unlock it when the vivo interface first appears.

The screen key continues to press and hold the volume plus key until the recovery mode is entered. First, select Erase Data/Restore Factory Settings.

Clear all data/restore factory settings; Erase the cache partition to clear the cache. After the interface jumps, select Restart the system immediately.

Restart the phone.

3. If the screen is still not bright, I suggest you go to our local after-sales service center to check your mobile phone: the address and telephone number of the after-sales service center can be found on the homepage of vivo official website-Services-Internet.
