What does it mean that the UI of Samsung mobile phone boot display system has stopped?

Through description, it is suggested that: 1. Try again after restarting your phone. 2. After uninstalling the recently installed third-party software, observe and initially rule out whether it is a software conflict, such as mobile phone housekeeper, games and other software. 3. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset-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.
