1. Confirm the application of generating screen lock hotspot information:
Take a screenshot in the hotspot information interface (press the power button+volume button at the same time), then enter the gallery to find the captured hotspot information picture, click the circle I in the upper right corner of the picture to view the picture path, and determine the application of hotspot information according to the picture path (for example, path: memory/picture/screenshot/screenshot-20210624-1665438).
2. Enter the setting interface and find the corresponding application shutdown notice:
Open settings, search to enter application management, find the previously confirmed application, click notification/notification management, and close notification permission. (After the notification is turned off, the normal message reception of the software may be affected. Please be careful. )
3. Check whether there is a set button on the hotspot information page. If yes, click and select the lock screen display to turn off.
4. Prohibit the application from using the floating window display: open the settings, search to enter the permission management, click the permission interface to open the floating window, and turn off the switch for the application that is not commonly used.
5. If you don't need to use the application of "generating screen lock hotspot information", I suggest you uninstall this application directly.
6. If the above methods still can't solve your problem, I suggest you back up your data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and then restore the factory settings.
