I used Xiaomi's mobile phone. I got up early and found that there was no text message in my mobile phone. What caused it? Is it because all the messages in the cloud service have been deleted?

Hello, where did you buy the mobile phone? SMS will not disappear automatically, nor will it be deleted by cloud services. Excuse me, is your mobile phone equipped with security software or has root permission turned on?

Xiaomi mobile phone comes with similar security software running in the background. If you install other security software, it may cause conflicts. It is not recommended that you install third-party security software, which may affect the normal use of your mobile phone.

For the sake of the system security of the mobile phone, please don't use root permission at will.

1. Software with root permission can completely control your mobile phone.

2. Opening root permissions may lead to system instability, crash, abnormal charging and other problems.

3. SMS, telephone and other functions may not work properly.

I suggest you back up your own data as much as possible, go to recovery and clear all data (turn off the phone, press and hold the volume up+power on button to enter recovery), upgrade the phone to the newly developed system with a line brush, and don't install the application that requires root permission for the time being to see if it can return to normal.

Thank you for your support and wish you a happy life!
