How to Reset Xiaomi Mi Mix 2S to Factory Settings: The Complete 2026 Guide

Why you need to reset Xiaomi Mi Mix 2S and when to use it

Resetting the Xiaomi Mi Mix 2S to factory settings is a radical but sometimes necessary step to restore the smartphone to health, removing all user data, apps and settings, returning the device to the “out of the box” state, most often in three cases:

First, if the smartphone started to slow down or spontaneously reboot after the MIUI update. This is a typical problem for devices of the year 2018 release, where the hardware does not always cope with new versions of the firmware. Secondly, the reset helps in preparing the phone for sale or transfer to another user - so you are guaranteed to delete all personal information. And finally, this is the only way to return to work if the Mi Mix 2S hangs on the logo or does not respond to touches after a failed rooting.
