In a report from The Korea Herald, Samsung will be upgrading the iris scanner on the Galaxy S9/S9+. This is expected to come in the form of the use of a 3MP camera versus the 2MP camera found on the Galaxy S8/S8+. Apparently the increase in megapixels is expected to allow for higher-resolution scanning, which should make it better/faster at recognizing users.
It is also expected to make it easier to recognize users in low-light situations, or when glasses are involved. “The iris camera lens will be improved to 3 megapixels from 2 megapixels of Galaxy S8 and Galaxy Note 8 to capture clearer images. The scanner will better recognize users’ irises even when they wear eyeglasses, move their eyeballs or are in a too dark or too light environment.”
During our review of the Galaxy S8, we had no issues with the iris scanner but improving it to make it faster at recognizing users will most definitely be a welcomed upgrade.
