Samsung wants to add an in-display fingerprint scanner and 3D facial recognition to its Galaxy S10 flagship device, according to a Korean news report from The Bell.

The company has not requested that its suppliers make iris scanners for the new phone, the report says. Instead of scanning irises, the Galaxy S10 would use facial recognition, while an in-display fingerprint scanner would offer an easier way to unlock the phones. Samsung Galaxy smartphones currently have fingerprint scanners on the back, which are a mild convenience for people with smaller hands (or left-handers on a Galaxy S8) as phone sizes have continued to grow over the past few years.
