What is the reason why the mobile phone camera can't be turned on?

You can check the Vivo phone in the following ways:

1. Go to Settings-Applications and Permissions/More Settings-Application Management-Find the camera-Store-Clear the data and cache, and then reopen it.

2. Uninstall third-party housekeeper software such as Tencent Mobile Manager and 360 Mobile Guardian, and then try to turn on the camera.

3. If the software can't turn on the camera, go to Settings-Applications and Permissions/More Settings-Permission Management-Find the corresponding software-Turn on the camera, and turn on the "Use Camera" permission in a single permission setting.

4. If the third-party software is used to take photos abnormally, it is recommended to uninstall and reinstall the software before opening it.

5. Take photos with different software for comparison test. If only one software is abnormal, it can be fed back to the software customer service; It is recommended to use the camera that comes with the system, which has better compatibility and effect.

6. Upgrade the system and third-party camera software to the latest version.

7. Enter Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore All Settings-Restore and Restore Settings Options. This operation will not delete files or software, but will cancel the password and restore all settings, including the set wallpaper, unlocking method, WiFi, default opening program, etc.

Backup can be made before operation: enter cloud service-device cloud backup-backup data type-system data-return-immediately back up some system settings and desktop layout that can be backed up; Cloud service-data synchronization-turn on WLAN and Bluetooth to synchronize data to cloud service.

8. If the above methods fail to solve the problem, please back up the mobile phone data in advance, take the mobile phone and purchase voucher to the vivo customer service center for testing, go to the official website-My-service outlet of vivo, select provinces and cities to inquire about the address and contact information of the local service center, or click the webpage link to search for the address of the service center.
