How to set Xiaomi's SMS background?

Hello, what version is your mobile phone system? I suggest you change a theme, and then click theme style-mashup-SMS theme and notification bar settings. See if it can be changed normally. If it still doesn't work, try:

1, you click the menu key of mobile phone-system settings-all settings-application-theme style to try to clear the data.

2. Try to back up and restore the factory settings.

Backup data: Go to System Tools/Security Center-Backup-New Backup and select all data for backup, which usually takes 3-5 minutes. Restore factory settings: Click the menu button of Mobile Phone-System Settings-All Settings-Backup and Reset-Restore factory settings-Open the delete application, close the formatted SD card, and click Reset Mobile Phone below.

3, you backed up the data, try to refresh, refresh method:

A please download the official ROM package, ROM download:/topic-mirom.html.
