2. Check whether the screen is locked or in safe mode. Check whether there is a screen lock password or pattern on the phone screen. If yes, please enter the correct password or unlock mode to unlock the phone. In addition, you can also try to press and hold the power button to turn it off and then turn it on to see if you can enter the main interface of the mobile phone normally. If the phone enters the safe mode, you can try to restart the phone to exit the safe mode.
3. Clear the home screen data. In some cases, there may be something wrong with the data on the home screen, which makes it impossible to display it normally. You can try to clear the home screen data to solve this problem. Enter the phone's settings menu, find the application or application manager, and find the desktop or home screen in the application list. Select an application, and then click Clear Data or Reset Options. Please note that this operation will restore the settings of the home screen to the default state, and personalization and layout will be lost.
4. Restore the factory settings. If the above methods fail to solve the problem successfully, you can consider restoring the factory settings. This operation will erase all data in the mobile phone and restore the system to the factory state. Be sure to back up important data before this operation, because restoring factory settings will lead to data loss. You can find the backup and reset options in the phone's settings menu, and select the option to restore the factory settings to perform this operation.
