Android phones have long been able to unlock with the user's face, but only after the iPhone X came in with the Face ID system, most manufacturers have begun to pay attention to this software feature. Despite the fact that Android's camera-only feature is not as safe as a password, a fingerprint, or Face ID, there seems to be a lot of demand from users that models that do not have it get updates. This time Nokia announces the implementation of the function on four of its top models
HMD Global announced through its Twitter Mobile Mobile account that the 8 Sirocco, 7 Plus, 6.1 and 8 models will receive a software update in the near future that will add the unlock option through facial recognition. Being a solution that uses existing hardware on phones, this system can certainly be "tricked" by a simple photo taken by printer or video, but this feature would be particularly useful for drivers who use the phone for navigation or music playback at the wheel.
Probably these four models were chosen because they are the ones with the best front rooms in the company portfolio, the Nokia 8 being the only phone that can shoot in 4K resolution on the front camera. Other devices such as iPhone X, Xiaomi Mi 8 Explorer and OPPO Find X benefit from laser projectors and infrared cameras for facial unlocking
The advantage of Nokia devices is that all of this list also integrates fingerprint sensors, which can be used in tandem with the facial recognition system. It is not clear when the update will be released, but HMD suggests it will come "in the coming months". Given that the launch of the new Android P is expected very soon, this feature will most likely be integrated into the upgrade to the next operating system
