Please try it according to the following two points:

1. Please back up the data first (by opening Settings ~ Backup and Reset ~ Local Backup ~ New Backup). ), then, enter the recovery mode, clear the cache, clear the user data, clear all data, and do not restore the settings and third-party security software in the mobile phone when restoring the backup. Try to use it normally.

2. If it still doesn't work, I suggest you brush the whole package again with a line brush according to the following method. You can refer to the following brushing tutorial:
