The face unlock feature is spreading like an epidemic, every other smartphone brand is trying to push their smartphone with the Face Unlock feature. Some brands like Xiaomi and OnePlus are even pushing new updates to the previous smartphone with the face unlock feature. Well, this feature is now way cooler than the coffee you might be drinking right now, so let’s talk about it a little more.
Face unlock feature was first available in Android 4.2 Jelly Bean where it uses the front-facing camera to click a picture and unlocks the smartphone when it sees that face again. Back then, the feature wasn’t secure but now the brands are taking the security thing seriously and making changes how the front-facing camera sees your face and when to be sure that it is actually you and not your picture.
So, now you know what it is and how it works, let’s see how you can get this feature on your Xiaomi Redmi 4/4X and Redmi Note 4. The process is straightforward but you have to be more careful while installing this because we are going to play with recoveries here. Also, your smartphone should be installed with the latest TWRP custom recovery and not rooted.
Steps to get the face unlock feature on Xiaomi
- Download the face unlock zip file according to your device; Xiaomi Redmi 4/4X and Redmi Note 4.
- Move the zip file on your smartphone and reboot it to the recovery mode.
- Tap on Install > select the face unlock zip file and after installation, reboot your smartphone by tapping on “reboot to system.”
- Also, do not clear the cache or anything which you do while installing the patch.
