One of the S8’s most exciting features is its new, more secure login facilities. With an iris scanner on the front, you simply look at the S8 and it will unlock and send you straight to the home screen. It will also enable you to log into secure services, such as your favourite banking facility, so even though you get a fingerprint reader on the back, there probably won’t be much reason to use it. Samsung has also bundled facial recognition technology, meaning you can log into your phone quicker than you would be able to with the iris scanner. While it’s the less secure option, it’s far more convenient.
