Okay, that’s it. So what’s the use of such chips =) I have LineageOS 7.1.2 installed.
Go to the settings – Security. (We are interested in Smart lock, but first we need to configure the screen lock, if it is not configured).
Press on “Lock screen”.
Set up the screen lock in any way you want, graphic key, PIN or password, and then go back to security. Click on “Smart lock”.
You can read what it is, press “OK”.
Choose the option “Face Recognition”.
Then click on configure, and that’s it.
Here is what the lock screen looks like when it is locked and is trying to recognize your face
And this is what it looks like when it recognizes your face.
To improve face recognition go to Settings – Security – Smart lock – Face detection – Improve face recognition, take several different pictures with different scenarios. You may have noticed “Voice recognition” in the Smart lock settings, predicting such revolutionary technology in Samsung smartphones.
Face ID recognition in Android is far from revolutionary, all we have now is the same Face Unlock, only modified. There Huawei is preparing something interesting, maybe they will do something normal, but it is simply impossible to recommend using this kind of unlocking, it is not convenient, it does not work at night. But if you always have normal lighting, you can use it. If Huawei will launch Face Unlock in the dark, that will be the only good Face Unlock. That’s it, that’s all I wanted to share, I just got it in my head.
Thank you for your attention!
To unlock your Android smartphone, there are several popular ways. For example, a PIN code, a pattern key, or a fingerprint. We’ve previously written an article about that, looking at each method separately. Today’s Xiaomi smartphones have a face unlock feature.
For the first time, users heard about such terms as “face id” or “face unlock” after the presentation of the iPhone X.
Face ID Xiaomi
Face ID recognition on Xiaomi has become another challenge for developers. At the moment, you can count on your fingers all the Xiaomi smartphones that officially support face unlock.
The Chinese company is always trying to offer advanced technology for its users. Therefore, the developers continue to work on the face unlock feature. So that as many users as possible around the world can take advantage of the new security feature.
After extensive validation, the development team has posted a list of Xiaomi devices that have officially supported Face ID. This is a facial recognition system that can fully replace the standard .
Face ID Xiaomi – list of phones:
- (year of release: 2018, May)
- (year of release: 2018, March)
- Redmi Note 5 / Pro (the global version is already officially on sale in Russia).
At the moment, it is indicated that the face unlock feature is supported in 5 regions:
- Hong Kong,
As for the Ukraine, and other countries in the message of the developers nothing is specified. As soon as new information becomes available, we will be sure to add it to the article.
What smartphones do not support Face unlock?
List of popular Xiaomi phones that do not officially support biometric face recognition technology:
- Xiaomi Redmi 5 Plus,
- Redmi 5,
- Redmi 4X,
- Redmi Note 4 / 4x,
- Mi 6,
- Mi 5,
- Mi A1,
- Mi Mix 2,
- Mi Max,
- Mi Note 3.
Note: this feature is not yet officially supported. But this does not mean that some custom firmware does not implement an analogue of facial recognition function to unlock the smartphone. You can find instructions for every phone on the list on YouTube.
An interesting fact is that the Xiaomi Mi Note 3 smartphone does not have facial recognition. This model, introduced in September 2017, was supposed to be the first to officially have functioning Face ID.
In the new version of Android there is such a wonderful feature as Smart Lock, which takes the locking and unlocking process to a new quality level.
Suppose you value your personal data very much, so you’ve taken a global approach to Android protection – installed a graphical code/pin-code, face control, enabled . How convenient is it for you to constantly enter an image code or a pin code to unlock your Android? Did you know that these types of passwords can be snooped on and later entered? Google decided to go even deeper to protect personal data and at the same time simplify unlocking and came up with a feature – Smart Lock.
How does Smart Lock work? Very simple! If you are in a “safe place”, or if there is a trusted device nearby, or if Android has seen your face, then your smartphone or tablet will unlock as if it was not locked (no passwords or keys needed)!
How do I enable Smart Lock?
- Go to Android Settings -> Security -> Screen Lock and choose one of the ways to lock your screens (except swipe the screen).
- Once the lock is created, go to the end of the list and select Trust Agents and activate Smart Lock.
- Go back to the beginning of the Security section and go to the Smart Lock menu 5.

Three smart unlock options will be available in front of you:
- Secure Devices – Unlocking without entering a password occurs if there’s a familiar Bluetooth nearby or you’ve brought your Android to an NFC tag;
- Safe Locations – unlock without entering a password if you are within a specified area;
- Face detection – unlock without entering a password if Android has detected that it is you who is holding it at the moment
- After activating one of these items, lock and test Smart Lock. Now you don’t have to enter the password every time because Smart Lock will detect if you need enhanced security.
Below is an example of how to enable Smart Lock and geo-locate:
- The reason why it is better not to use Smart Lock
- Even though Smart Lock on Android can make your life much easier, there are still good reasons not to use it. Here are some examples of why this “thing” can harm you!
If you have location based unlocking enabled and you are right in that “safe place”, an intruder can take advantage of this feature, distract you and steal your data.
If the watch or something else that was tethered to Smart Lock was stolen, an intruder could steal the data, again, by distracting you or by stealing your smartphone.
If the phone is stolen and a smart lock has been installed on it, then being close to a “safe place” where Android unlocks can easily steal the data.
Hence, we can conclude that Smart Lock can facilitate the use of the device, but if you notice something wrong, it is better to disable this feature and use the old-fashioned graphic keys and pin codes.

For the first time, the function of unlocking the screen with photos taken by the front camera of the smart background appeared in the Samsung Galaxy Nexus. More precisely, not even in the smartphone, but in the operating system Android 4.0.
So Xiaomi and Apple are not pioneers. But the Cupertinians have set the standard for the future. Can the copycat from the Celestial Empire at least approximate its result?
Why does Xiaomi need its Face ID?
Unlocking with the front-facing camera is often glimpsed among Android smartphone specs. It’s usually a simple snapshot comparison that’s easy to fool with a simple medium-quality photo. For example, by holding up another smartphone with a screen shot. It also requires you to turn on the screen.
Xiaomi’s own Face ID was introduced as a killer feature of the Mi Note 3 sub-flagship (). Somehow it had to show that the odd mid-range smartphone could actually qualify for a place in the top tier. The camera is great, the look and the screen are above reproach. But the result is not a flagship, but a long-lived mid-range with a great camera. Although I really liked it.
Face ID could have saved the smartphone: a feature worthy of a flagship. You’re taking a swing at something sacred, the iPhone X! In its current form, Xiaomi Face ID got first the Mi Note 3 and then all other Xiaomi smartphones. How? With a system update (the Mi Note 3 had the feature back in MIUI 8.5). A little strange, because real Face ID does not work without a hardware base, a special camera and unique software. Has Xiaomi managed to get by with just a neural network that scans photos? Apparently, yes.
How does real Face ID work?
As you know, Apple Face ID is not just a software feature. It’s complicated, and above all, it’s hardware. It uses TrueDepth cameras to recognize the owner’s face, scanning a structural map of the face.
To create it, 30,000 created into the TrueDepth system by a projector are used. These are scanned by the infrared camera, followed by the creation of an infrared image. It is then transferred to a separate module of the Secure Enclave processor, where it is checked and matched against the wearer’s previously defined facial dot structure.
Thanks to this, the iPhone X recognizes the wearer even if they let go of their beard or add glasses to their image. What’s more, twilight, poor lighting or darkness are no problem for true Face ID either.
There are few prerequisites for Apple’s facial recognition system to work properly – your eyes must be pointed at the camera. That’s it. You can change clothes, makeup, and grimace. The smartphone will be unlocked no matter what.
What does Xiaomi have to say about this?
How does Face ID work for Xiaomi?
Initially, you need to enter your face data into the database. After that, the system will ask you to enter the password you set earlier or create one. After that, there will be a warning that this unlock method is less secure compared to a finger scanner or password.
The system will then ask you to enter or create the password that you set earlier. After that, you will be warned that this unlock method is less secure than a finger scanner or password.
The last step is to configure the unlock setting. The first switch allows you to use your face to unlock your smartphone, and the second switch will allow unlocking when the screen lights up from a new message.
You can use face unlock either paired with the finger scanner or on its own as a separate system.
Tested it, it works. Convenient, but…
Once the picture is entered into the settings, you can start testing. The test was done in 2 stages one month apart: for the sake of the experiment I had to let go of the beard.
The first trick Xiaomi Face ID – no need to turn on the screen. It is enough to point the front camera to your own face. I picked up the phone, did nothing with it – and the first time the picture was not recognized. The second attempt was successful. The unlocking was instantaneous.
As expected, the facial hair was an insurmountable obstacle. Subsequent tests showed that it was the mustache. If you cover your chin with a scarf, the screen unlocks. The mustache, released already after the first frame was entered, turned out to be a hindrance.
If you close your eyes, the Mi Note 3 also refused to unlock the screen. Apparently, this is how the protection against unlocking at the moment when the owner is asleep works.
But if you take a picture of the smartphone wearing sunglasses, and then take them off – the recognition system refuses to recognize the owner. Both from the first and the second time. Interestingly, on the contrary (picture taken without glasses, an attempt to unlock is made wearing glasses) unlocking is almost instantaneous.
I was not able to fool the system with the photo. A similar face does not work either. Although the twins will probably be able to use each other’s smartphones.
The only real enemy of Face ID, created by Xiaomi – bad lighting and darkness. It uses a regular front-facing camera, which does not work in the IR spectrum. Therefore, it needs enough light to unlock the screen to take a photo. Getting the screen close to your face is not a good option.
For the necessary light, which the proprietary Face ID requires, a completely different measure. Can you take intelligible selfies? Then the smartphone will unlock. Otherwise, only a fingerprint or password.
Instead of the bottom line. Everything works, but Xiaomi is ashamed
Unfortunately, not perfect work killed the innovation (you could say that) at the root. Xiaomi has cut the facial recognition feature from all global (multilingual international, for the European market) firmware.
Most modern cell phone users want to protect their data and device from being used by outsiders. Due to this need, developers come up with a variety of locking methods. For example, Android-based devices first used a PIN to protect personal data, then came the graphical key, which has been popular for a long time and is just as good as the new unlocking method via fingerprint scanner.
The latest innovation in device locking is the face unlock feature. This technology is no longer a novelty, but has only recently become popular and sought after by many technology manufacturers. Known for its quality cell phones and affordable prices Xiaomi is also not behind the new standards: it has implemented this feature in one of the latest firmware updates MIUI 9 and 10 and added Xiaomi Face ID on those mobile devices that originally did not support it. What Face ID is, how to set it up and use it, which models support face unlocking – our new article about it all.
Features and differences of Xiaomi Face ID
The first time the term “Face ID”, aka “Face Unlock” became known to a wide range of users after the presentation of the IPhone X from Apple. Xiaomi has immediately adopted the technology and installed it on its latest phones.
The main feature of Xiaomi’s Face Unlock is that it does not require any additional devices, applications or scanners to work correctly. One built-in webcam, or front-facing camera is enough. The technology is able to work through neural networks. The accuracy of its work is quite high, but still Face ID Xiaomi slightly inferior in quality of work of a similar function on the IPhone X. This is due to the difference in the technical execution of the above technology.
The face recognition function of the Apple product involves not only a webcam, but also dedicated Infrared radiation sensors and additional technologies. All this together makes it possible to simultaneously process up to 30.000 different points of the face. The built-in software generates a detailed structural depth map and infrared spectrum image of the face. And a special fragment of the microprocessor’s neural core presents the map in a mathematical form, which in turn is compared with the already registered face data. If they are a perfect match, the gadget is unlocked. The technology is quite reliable. It will work even if the user wears glasses or grow a mustache and beard.
As for Face Unlock on Xiaomi, most often the technology uses only one scanner without all the additional sensors. The only exception is the Redmi 8, which has an infrared sensor. Despite this, the scanner can recognize the depth of the face and detects the presence of accessories, such as scarves and hats, for example. The only problem arises only with facial vegetation, which the scanner has not been taught to detect. An additional bonus is the detection of whether or not a person’s eyes are closed. If the eyes are closed, the mobile device will not unlock. This innovation was created by the developers with the purpose that it would not be possible to unlock the gadget from the face of a sleeping person. Photo-based unlocking, which is not unimportant, will also not work.
Xiaomi models that support Face ID
The in-demand facial recognition technology has become one of the significant challenges for the brand’s developers. The manufacturer is constantly trying to offer its users the most modern and up-to-date technology. For this reason, developers continue to actively work on the Face ID function, so that as many users as possible all over the world can try and appreciate this security feature.
At the moment the devices of the range Xiaomi, which officially support the aforementioned technology, very few.
After extensive testing the developers have made available a list of phones that support Face Unlock:
- Redmi S2.
- Redmi Mix 2S (May 2018)
- Redmi Note 5 (May 2018)
- Redmi Note 5 Pro (May 2018)
- Mi 8 (August 2018)
At the same time, from the message of the developers, the facial recognition feature is supported so far only in five regions:
- Hong Kong
Xiaomi models not supporting Face ID
The list of the most popular models that do not support the technology is still more.
- Mi Note 3: the model introduced in September 2017, the first in the lineup to officially have the technology working
- Mi A1
- Redmi 4X
- Redmi Note 4
- Redmi Note 4X
- Redmi 5
- Redmi 5 Plus
Despite the fact that the above models do not have an official feature, it is possible that there is a Face ID analogue in some tricky firmware. In online resources, particularly on YouTube, you can find instructions on how to enable unlocking the device by face recognition for each model.
Also the function may unexpectedly work due to new updates to the custom shell.
How to enable Face ID Xiaomi
What to do if your mobile device doesn’t have Face ID working even though the model suggests it? No need to worry and look for the nearest service center. Let’s try to “teach” your phone to recognize your face yourself.
In order to use the modern Face ID technology on any Xiaomi gadget that supports this function, it is enough to follow our step-by-step instruction:
Remove the mobile device from the lock available way.
Go to “Settings” through one of the main screens or by lowering the screen.
Scroll down. Find the “Lock screen and password” or “Lock and protect” in the “System and device” section. Click.
Find “Add face data” and open it.
Now you need to follow the instructions that appear on the screen of your gadget. The camera will be turned on, and in the circle that appears, you must put your face.
Wait for the end of the scanning and saving processes (no more than 5-10 seconds).
If for some reason the saving gets confused, the device will offer to try again. There is nothing wrong with this, it is quite a common mistake.
If you can’t install the function due to the absence of the specified boxes and windows, check again whether this technology is supported on your model. For example, on Mi 8 Face ID will be installed without the slightest problem, while on Redmi 5 face unlock will not work under any conditions without additional settings and in the currently existing firmware.
In conclusion, we can say that the face unlock feature, or Face ID, is one of the most interesting additions in modern phones. Let’s hope that in the near future this technology will function on more models of Xiaomi mobile devices.
Now you know what Face ID on Xiaomi is. We hope that our article was useful for you!
