After the Samsung S4 update, why does the screen always bounce back when you drag it?

1. Turn the phone on and off again

2. If the mobile phone case has a protective cover, remove it and test it

3. Back up mobile phone data (phone book, text messages , multimedia files, etc.), restore the factory settings (enter the phone settings-account-reset-restore factory settings)

If the problem persists, in order to more specifically understand and solve the problems on the phone, it is recommended to Send the mobile phone to the nearest Samsung service center for testing. The service center will determine the specific problems and accessories of the mobile phone based on the test results.
