Xiaomi 3 is connected with wifi, rice chat and free SMS.

I suggest you try the following methods:

1, click Settings-Apply-All-Find Software-Clear Data, clear software data and open it.

2. After uninstalling, download and install the corresponding program again through Xiaomi App Store.

3. If all the software is opened slowly or has problems, you can back up and try to clear the cache and user data during recovery. Methods: Press and hold the "Volume Increase Key" and then the "Power Key" when the power-on screen appears, and then let go to resume. Select simplified Chinese > clear data > clear cache+clear user data. Tip: The touch screen is temporarily disabled in the recovery state. Please confirm with the "Power Button" and select the "Volume Button".

4. If the corresponding program has problems after the above operations, and other software programs are normal, it can be judged that the program is incompatible with the system. You can try to change other versions of the program or game.

I suggest you back up your system version and try again.
