Samsung mobile phone suddenly crashed, some software was lost, and the download was wrong.

From your description, I suggest you:

1. Restart the machine and try.

2. If an external SD card is inserted into the fuselage, take it out for observation.

3. After uninstalling the recently installed third-party software, observe whether it is a software conflict, such as mobile phone housekeeper, games and other software.

4. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset/privacy/private-restore factory settings).

If the problem of restoring factory settings still exists, it is recommended to send the mobile phone to the nearest Samsung service center for testing and further processing. Please visit the address and contact information of the service center:
