If you know, talk about how to solve the problem of Apple's mobile phone software flashing back.

Apple's mobile phone has an application flashback processing method: restart the application, close the application and reopen it. Second, restart the device, turn it off and then turn it on. Third, check whether there are any IOS and App updates (you may need a Wi-Fi connection to update some apps). Fourth, install other applications from the App Store. Try to install another application that is not installed on the device. To find a free app from the App Store, be sure to use the same Apple ID that you used when downloading the problematic app. 5. Delete and reinstall the App (after the app is deleted, the usage records and personal data related to the app will be lost and cannot be recovered. Please think twice before deleting). Sixth, contact the App developer. Find the app in the App Store, tap the app, then tap Comments, and under App Store customer comments, tap App Support.
