OPPO。 How to restore the video that came with the mobile phone after it was deleted?

If the self-contained application is deleted, it can be restored by the following methods: 1, non-root mobile phone, factory settings can be restored, please back up the data before restoring (Settings-System More-Restore factory settings, please do root check "Completely Clear"); 2. If ROOT passes the mobile phone, you need to download the official firmware package to refresh the system or go to the local customer service center for processing.
