What should I do if I turn off my phone or wait for Xiaomi 2S because the SMS doesn't respond?

This kind of problem can be solved through Sanqing!

Xiaomi's mobile phone recovery operation is to clear the cache, clear the user data and clear all the data, so the "three cleanups" are obtained in this way. Then, whether the legendary Sanqing must be implemented or not. When the phone is turned on, enter the system update, press MIUI key, select Restart to Restore, click OK, and wait for the phone to restart. Press and hold volume plus in the off state, and then press and hold the power button.
