Samsung introduced iris unlocking and face recognition with the Galaxy S8 to increase the accuracy and speed of unlocking the phone, and the same security features were ported to the Galaxy S9. However, with the Galaxy S10, Samsung might have to remove the iris scanner in favor of the in-screen fingerprint reader, a 3D facial recognition system, or add both. > A report from the Korean newspaper The Bell has said, quoting reliable sources from the industry chain, that Samsung hasn’t bought iris sensor samples yet for its upcoming flagship the Galaxy S10. Based on this information, the report surmised that the Samsung may not incorporate the iris scanner technology on the Galaxy S10 and instead go for fingerprint recognition and 3D face recognition, or perhaps both.
