When Samsung Galaxy Note 7 was unveiled back in August 2016, it came with one feature that had never been seen on a Samsung smartphone before it – an iris scanner.

While this feature received lots of love from the people who got a chance to interact with it before the phone turned into a health hazard, there are some who saw it as a mere gimmick. With the release of the new Samsung Galaxy S8 and S8+, the feature has made a major comeback and this time, there are some real improvements on how it works, especially when it comes to accuracy.

Whether you have glasses on or not, the current iris scanning feature will unlock your device, although there are some people who are still experiencing issues when using glasses while trying to stare into the iris scanner for authentication.


Apparently, Samsung was aware of the inaccuracies that accompany the iris scanning feature when it comes to unlocking the Galaxy S8 and S8+. As a result, the South Korean tech giant added another biometric authentication feature to the handsets that is reportedly meant to aid in getting fast and more accurate results when trying to unlock your phone without using the fingerprint scanner located on the back panel.

Using facial recognition, you don’t even need to concentrate your eyes on the Galaxy S8 or S8+’s screen. Instead, the feature will simply scan your entire face and match it with what it has in its database, thus giving you access to the handset. There’s no doubt that this is the best and easiest ways of gaining access to your phone. In fact, it is easy to say that this is the more secure feature the Galaxy S8 and S8+ have as far as protecting personal data on the devices is concerned.

Interestingly, there’s a new report that has just surfaced from South Korea with very daring claims. Where Samsung is touting the Galaxy S8 and S8+ as the most secure smartphones on earth thanks to the combination of a fingerprint scanner, iris scanner and facial recognition, the report claims that the latter feature is still miles away from becoming the go-to method for the most secure authentication.

Apparently, industry insiders are of the view that the facial recognition feature has at least another four years of development before it becomes as secure as Samsung claims it to be. There have been claims that the feature will soon be integrated into mobile banking, but according to the source, it’ll take at least four years before this dream is actually realized.

“In order for facial recognition to be exclusively used for mobile financial transactions, it would take over four years,” a Samsung source told The Korea Herald. Apparently, this is due to the “current camera and deep learning technology levels” that are not to the right standards, which means the feature is yet to be considered reliable and consistent. Or in much simpler terms, facial recognition is just another gimmick from the South Korean tech giant, at least for now.

In fact, early tests have revealed that it is easy to fool the facial recognition feature on Samsung Galaxy S8 with an image of the owner and you’ll be granted access into the phone. At the moment, it appears that the tech giant has no major plans of upping the performance of the new facial recognition feature, especially since Galaxy S8 users can still rely on fingerprint and iris scanning for mobile financial transactions.

Nonetheless, industry experts are adamant that now that the feature is here, Samsung and other OEMs will invest heavily in making sure that it indeed takes off and becomes the go-to feature not only for financial transactions, but for all basic authentication purposes. But for now, you’ll have to stick with the fingerprint or iris scanner.
