What should I do if the information that comes with Meizu mobile phone goes in and flashes back?

This situation is generally a software conflict. See what new software has been installed recently and then uninstall it, or directly restore the factory settings. Recovery method: Setup-storage and backup-restore factory settings-start reset.

Detailed operation method:

First, open the "Settings" of your phone.

After entering, scroll down to find "storage and backup" and click enter.
