Here’s how you can try the widely-favored face unlock feature on your Redmi Note phone. Follow the detailed instructions in this guide to enable Face Unlock on Redmi Note 4.
Android users are constantly looking for new and easier ways to unlock their phone. While fingerprint unlocking is still the fastest and more efficient option, people are tilted towards the Face Unlock method ever since the launch of the iPhone X, featuring FaceID. The feature has already spread across various OEM devices like Huawei and OnePlus. Xiaomi, on the other hand, sneaked in the competition by announcing the Face Unlock feature for its latest Note series phones. The feature has already made its way to the recently launched Redmi Note Pro via the MIUI V9.2.4 software update. However, the development community isn’t far behind when it concerns the Note 4. To your surprise, you can now enable Face Unlock on Redmi Note 4, unofficially. The process is fairly easy, so head down below.
XDA member shubhandu, along with 4pdu forum members (oc01 and Barnum) has compiled a TWRP-flashable mod that’d allow users to enable Redmi Note 4 Face Unlock feature. The mod has been confirmed to be working on MIUI V18.104.22.168.NCFMIEK (Stable) and MIUI 9 8.2.8 (Developer) stock ROMs. The zip installs a modified system.apk, miuikeyguard.apk and the required lib files in order to enable Face Unlock on Redmi Note 4. The developer has recently added support for more Xiaomi devices including Redmi 4/4X and Mi Max Prime.
In order to flash this mod, you must have TWRP recovery installed on your Note 4. Also, take a Nandroid backup of your current ROM before installing this mod since there is no rollback zip provided yet.

- First, download the TWRP flashable mod:
- Connect your Redmi device to the PC using the USB cable.
- Enable “Transfer files” USB mode.
