Hello!

Sorry for the inconvenience caused to you. Based on your description, it is recommended that you try the following operations:

1. Try restarting your phone.

2. Try to restore factory settings through "Settings->More Settings->Restore All Settings"

3. You can enter Settings->More Settings->System Upgrade -> Check for updates now -, follow the prompts to download the upgrade package, click Verify and install, the phone will restart and automatically enter upgrade mode to upgrade your phone's system.

4. Try to clear abnormal data through "Settings->More Settings->Restore Factory Settings->Clear All Data". Note: This item will lose all user data stored on the mobile phone, including phone book, text messages, third-party application software, and related account information.
