What should I do if my Xiaomi 2 SMS prompts that this application is not installed? Help!

According to the problem you described, I suggest that you back up the important data first, then restore and clear all the data, and don't restore the data for the time being after booting to see if the problem can be solved. (Backup: Security Center-Backup, backup the data you need. Clear data: press and hold the volume up button and the power off button when the boot screen appears, and then let go to resume. Enter Recovery & gt Chinese > clear data > clear all data. )

A more detailed description of the problem will help netizens understand your troubles and help you solve the problem more accurately. Thank you for supporting Xiaomi mobile phone!
