To be clear, the iris scanner will still be offered in the Galaxy S8, but Samsung made the decision to add the facial scanning to offer you another way to unlock your device, and perhaps do it more efficiently. While the predecessors have significantly smaller displays, the form factor of the Galaxy S8 with a 5.8-inch display increases only a little, and the large difference in display size is due to thin nearly bezel-less nature of the upcoming smartphone. The handset may feature facial recognition technology, adding another layer of security alongside a fingerprint and iris scanner.
If you've been following all the Galaxy S8 rumors, the handset will likely offer iris scanning and a built-in fingerprint reader, but it seems that those features aren't enough.
"Due to some limits of iris scanning such as speed and accuracy, we have chose to add facial recognition to the Galaxy S8", a Samsung official was quoted as saying.
Come the end of this month, the world will finally know what the Galaxy S8 looks like - that is, if they haven't already seen the mountain of obligatory leaks that has built up in recent months. The official launch, on the other hand, was earlier confirmed to be on March 29, with events happening in NY and London. But this isn't any regular portrait of the upcoming Galaxy S8 family, for smack dab in the middle of the picture is the Samsung Galaxy Note 7. The official said that the system allows user authentication in under 0.01 seconds.
The latter sports the same star-themed wallpaper seen in the alleged official render of the Galaxy S8, increasing the chances of it being the real deal.
