Xiaomi 4 opens a new window and returns automatically.

I suggest you check whether the data attempt is normal!

The method is, back up first ~ then turn it off ~ press and hold the volume key and power key at the same time ~ after entering, use the volume key to select, the power key to confirm, select Clear Data, Clear Cache' to clear all data, which is Sanqing.

When restoring the backup, set the software in the mobile phone, and only restore personal data such as contacts, text messages and notes. Go to Xiaomi App Store to download the software. Try to see if it is normal!

PS: The way to resume is to turn off the power first, and then press and hold the volume button and the power button. Once inside, the touch screen is useless. You must use the volume button to select the power button to confirm, select Simplified Chinese ~ Clear Data ~ Select Clear Cache, Clear User Data and Clear All Data.

Then choose to turn off, and then press and hold the power button to turn on.
