If it cannot be changed after operation, it is recommended to restore the factory settings of the mobile phone (Settings-Reset-Restore Factory Settings). Before restoring the factory settings, please back up the important data stored on your phone in advance, such as phone book, SMS, photos, video files, etc. Because everything stored on the phone will be lost after the factory settings are restored.
