How to solve the problem of virtual text messages not ringing when the time is up?

The main reason why the alarm does not sound when the time is up is that the APP cannot wake up at the time you set after being killed by the system. Therefore, it also caused the problem of not ringing at the time.

The APP needs to be added to the whitelist to avoid being killed by the system. Two steps are required:

1. After setting the virtual phone call or text message, avoid exiting the APP. You can directly press the Home button to exit, but please do not exit the APP directly to avoid the APP being killed by the system.

2. Lock the virtual phone text message and add it to the system whitelist.

3. The power saving strategy needs to select unlimited, allow the installation of applications from unknown sources, and enable the lock screen display and background pop-up interface permissions
