1. Please restart your phone and see if you can use it again.
2. The new version of the system improves the compatibility and stability, and optimizes the performance. Please go to Settings-System Upgrade (some models are Settings-My Device -iQOOUI Version) to check the system version information. If it is not the latest version, it is recommended to upgrade the experience.
3. If there is a splash screen when using third-party software, it may be caused by incompatibility between the software and the system. It is recommended to enter the app store to download the latest version of the app.
4. Enter Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore all settings.
Note: Restoring all settings will not delete any data or media files, but only restore all settings of the mobile phone, and some third-party application accounts need to log in again. Please make sure that it will not affect the use of the software before operation. For your data security, it is recommended to back up your mobile phone data in advance before operation. (You can go to Cloud Service-Device Cloud Backup-Backup Data Type-System Data-Back-Back up some backup system settings and desktop layout immediately; Cloud service-data synchronization-enable WLAN, Bluetooth, etc. Synchronize data to cloud services)
5. If the above methods can't be solved, please back up the mobile phone data in advance and take the mobile phone to vivo customer service center for testing and processing. (Address and contact telephone number of vivo customer service center: Go to the "vivo official website /vivo Mall" APP-My service outlet or click this link to enter and select your current city to get it. )
Tips: It is recommended to bring relevant purchase vouchers (such as purchase invoices/warranty cards/ID cards) before going, and call the staff of the service center in advance to ensure that the staff will go again during normal working hours, avoid running empty, and pay attention to safety on the way back and forth.
