If this happens, there may be an error in the third-party software downloaded on the phone or the internal application. We recommend that you:

1. Settings-Look for "Application Manager" - (All) - Find unusable apps - (Storage) - Clear data.

2. If you downloaded third-party software, it is recommended to uninstall the software and reinstall it or download and install other versions of the software to try.

3. If this prompt will also appear when running a built-in program, check whether the phone has the latest firmware version and upgrade the machine to the latest version.

4. If you still cannot run this application, please back up the data in your phone (contacts, photos, etc.) and then restore the factory settings.

If the problem persists, please bring the purchase invoice, repair card and machine to the Samsung service center, and professional after-sales engineers will help detect it.
