what is miui 10????
Google is your friend...
An operating system for xiaomi phones.
Go to www.google.com, type the exact same question in search bar.
Miui is an android custom rom from xiaomi its commonly found on xiaomi phones, and can/has been ported to other devices
plenty of videos about it on youtube
You'll get an answer after you do this a hundred times
And further more, in my opinion MIUI is not worth bothering with, especially if you prefer stock android/near stock abndroid
Miui 10 is just awesome, op should also opt for similar updates in its Oxygen e.g. In gallery rotating feature with two finger
