Comparison of Face Unlock in Different Android Devices


Face unlock technology has been revolutionizing the way we access our smartphones, making it faster, easier and more secure. With the evolution of Android smartphones, Face Unlock technology has also evolved, and it is now available on a wide range of Android devices. In this article, we will compare the Face Unlock feature in different Android devices and explore its usefulness and effectiveness.

Firstly, let’s understand the basics of Face Unlock. It is a biometric authentication method where the user’s face is used to unlock the device. The front camera of the smartphone captures a 3D scan of the user’s face and compares it with the stored pattern to grant access. This technology is based on facial recognition algorithms and has become the most preferred method of unlocking smartphones.

One of the pioneers of Face Unlock technology was Google, with its launch on the Google Pixel devices in 2017. The Pixel’s Face Unlock feature uses an infrared illuminator, a structured light system, and a Time of Flight (ToF) sensor to create a 3D map of the user’s face, making it highly secure and effective even in low light conditions. The face data is stored locally and not on Google servers, ensuring user privacy.

Samsung’s Face Unlock, on the other hand, uses a front camera for facial recognition and is available on most of its devices. However, it is not as secure as Google’s Face Unlock, as it can be easily tricked using a photo or a video of the user’s face. Samsung also offers a feature called “Intelligent Scan,” where it combines Face Unlock with Iris scanning for added security. However, it comes at the cost of speed, making it slightly slower compared to the Pixel’s Face Unlock.

Many other Android devices, such as OnePlus, Xiaomi, and Huawei, have also incorporated Face Unlock in their devices. OnePlus, known for its fast and smooth user experience, offers a Face Unlock that is almost as fast as the Pixel’s but lacks the 3D mapping technology. Xiaomi and Huawei also offer Face Unlock on their devices, but they are not as fast or secure as the other mentioned brands. Additionally, Huawei also offers “Smart Lock,” which keeps the device unlocked in certain trusted locations or when connected to trusted devices.

Face Unlock can also be customized in some devices, such as the LG G8 ThinQ, which offers Control Center LockScreen, allowing users to access frequently used apps by swiping their face in a specific direction. It also offers the option of using Face Unlock to hide sensitive notifications until the user’s face is recognized.

Apart from unlocking the device, Face Unlock can also be used for secure app locking and authentication. Apps such as AppLock and Norton App Lock offer the option to lock apps using Face Unlock, providing an additional layer of security.

In conclusion, the Face Unlock technology in Android devices has come a long way, with companies continuously striving to improve its speed, accuracy, and security. Google and Samsung lead the pack, providing highly secure Face Unlock features with added security measures. Other brands have also incorporated this technology, but they are not as advanced and may lack some features. Furthermore, customizations and additional features also add to the overall experience of Face Unlock on Android devices. With the constant evolution of technology, we can expect even more advancements in Face Unlock, making it an indispensable feature in our daily lives.
