Face unlock only via front camera
[hide]Huawei P20 Pro Face Unlock[/hide]The Huawei P20 Pro, as well as many other Android smartphones using the Android feature Face, Unlock also want to register the owner’s face. But unlike Apple’s Face ID, face recognition in the Huawei P20 Pro does not register an anatomically accurate 3D model of the smartphone owner. Biometric matching does not take place on Face Unlock. Instead, the front camera of the Huawei P20 Pro needs a two-dimensional image, which is not captured by an infrared sensor but via the selfie camera. The reason why Huawei’s, Asus’, and Xiaomin’s notches can be significantly smaller than those of the iPhone X. There are no sensors within the notch that could be relevant to face unlocking. The datasheet of the Huawei P20 Pro speaks of a depth sensor.
The security differences were not so bad at the introduction of fingerprint sensors. Relatively quickly, the Android and the Apple camp could gather together and provide a secure method for unlocking the smartphone for both user groups. What mobile phone users and technology experts should want is not the competition for the fastest unlocking method and the smallest notch, but the fight for the best innovation between smartphone manufacturers, who are also in a head-to-head Deliver race.[hide]Huawei P20 Pro Face Unlock[/hide]

Huawei P20 Pro without infrared sensor
[hide]Huawei P20 Pro Face Unlock[/hide]The reasons for this can be found above all on a technical level, as the differences between Apple’s Face ID and the Android feature Face Unlock could not be greater. Apple has missed its comparatively hefty anniversary iPhone an A11 bionic chip whose TrueDepth camera turns the user’s face into a mathematical model. The sensor projects 30,000 infrared dots onto the face and transmits the information to the Neural Engine of the A11 Bionic chip. In some YouTube videos, this is easy to see, because here the unlocking of the iPhone X was made visible.
According to Apple, the A11 bionic chip transforms the user’s depth map and infrared image into a mathematical representation and compares this with initially registered facial data. These must deliver iPhone-X users either during the installation of the iPhone with circling head movements or retrospectively within the attitudes with “face ID & code” furnish. The 3D image of the iPhone X user as a reference to unlocking also allows the functionality despite beard, makeup or sunglasses.[hide]Huawei P20 Pro Face Unlock[/hide]
Faster than the iPhone X
The iPhone X has been the subject of numerous keynote speeches in recent months that were not held by Apple. As manufacturers make comparisons in terms of processor performance, benchmark values in the multi-and single-core area, benchmarks of dual and triple cameras. It is compared in terms of battery, compared to what it lasts. At the advertising level, this is understandable only in the areas in which the Android smartphone on paper scores better than the iPhone. Like the face recognition in the new Huawei P20 Pro. This is also much faster in our test. It is also much more reliable.[hide]Huawei P20 Pro Face Unlock[/hide]
The word “reliable” is but with caution to enjoy. The Huawei P20 Pro “reliably” unlocks the display during our test in darkness in nine out of ten cases. The iPhone X unlocks the display in darkness in our test in seven out of ten cases by face recognition “reliable”. But: The iPhone X protects its content via Face-ID in ten out of ten cases “reliably”.[hide]Huawei P20 Pro Face Unlock[/hide]
