What if there is no popup window for SMS after Xiaomi upgrades v6 system?

What version is your mobile phone system? Try the following:

1, 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.

2. If your system is not the latest system version, I suggest you open the network and try to update the system version. The new system version will add some new functions and fix some problems of the old version.

3. If it still doesn't work, I suggest you try to back up and empty the data, which may be caused by data interference. Backup: Security Center-Backup-Create a new backup and back up 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.

4. You can also try using a line brush machine. The line brush is more thorough. I suggest you make a backup before you brush the computer.

Please download the official ROM package. ROM download:
