Face unlock is getting really popular and Redmi Note 5 Pro brought along with itself the ability to quickly unlock your device using just your face. This is a new feature that will be implemented in most MIUI builds in the coming future but if you want to get this feature immediately on your older Redmi devices like the Note 4 and Mi Max prime then this is the guide you have been looking for. So let’s take a look at how you can enable face unlock on redmi devices running older MIUI versions.
If you are running MIUI V9.2.4 then you probably already have face unlock enabled on your device and this guide won’t be of much use to you but if you are running an older MIUI version like MIUI V220.127.116.11.NCFMIEK or MIUI 9 8.2.8 then you can easily get face unlock on your device using this easy method. The Mod file includes a modified system.apk, miuikeyguard.apk along with the necessary lib files in order to enable Face Unlock on Redmi Note 4, Redmi 4/4X and Mi Max Prime.
We know for certain that it works on MIUI V18.104.22.168.NCFMIEK and MIUI 9 8.2.8 and we do not guarantee that it will work on other version of MIUI so proceed with caution as this can brick your device. You have been warned.
