Make sure there are no stains on fingers and fingerprint recognition areas. If so, please clean them and try again.

2. Fingerprint changes affect input.

Changes in fingerprints (such as dry fingerprints, peeling fingers, sweating, etc.). ) may affect the success rate of fingerprint input. When your fingers are wet, you can input them or change your fingers.

3. Check whether the third-party film is used (screen fingerprint mode is applicable).

The original film used in the screen fingerprint model will not affect the fingerprint recognition effect after special treatment. The use of third-party film may affect the success rate of fingerprint unlocking or entry, and it is not recommended. You can go to the customer service center to change the official mask and re-enter the fingerprint.

4. Upgrade the system

Please upgrade your mobile phone to the latest version for viewing.

5. Restore all settings

Go to Settings-System Management-Backup and Reset-Restore all settings, and then follow the onscreen instructions.

* Note: Restoring all settings will not delete any data or media files, but only restore all settings of the phone. Some third-party application accounts need to log in again. Please ensure that the use of the software will not be affected before operation. Important data can be backed up in advance.

6, service center testing

If the above methods fail to solve your problem, please back up your mobile phone data in advance, take your mobile phone and purchase certificate to the vivo customer service center for testing, pay attention to the official account of WeChat "vivo" or "vivo customer service" to inquire the address and telephone number of the service center, and suggest calling before going to ensure that a staff member receives you before going, so as not to waste precious time.
