What if Xiaomi's mobile phone is deleted and the calendar can't be opened?

I suggest you brush the complete MIUI package (stable version, development version, you can choose according to your own use) and software system problems with a wire brush. A wire brush can solve it.

First use the backup tool of Xiaomi mobile phone to back up, open Settings ~ Backup Reset ~ Local Backup ~ New Backup, and then enter the recovery mode to clear the data.

Backup is to package the data in the mobile phone and back it up to the memory card (Mi2 series and Mi3 mobile storage devices). Clearing the data three times will only clear the data stored in the mobile phone, not the storage device.

Note: The flash memory of Xiaomi mobile phone 4, Xiaomi mobile phone 3 and telecom version adopts the new version scheme. In the new scheme, all the memory of the mobile phone will be intelligently partitioned with the use of the user, which can save the user's memory better. At the same time, all data in the flash memory of the mobile phone (including photos, music, videos, game packets and other data) will be cleared during the three-time cleaning to ensure stability. It is recommended that you use the computer to back up important data before brushing the computer.
