The S10 line comprises five models with various hardware specifications; the main S10 and S10+ respectively feature 6.1 and 6.4-inch 1440p "Dynamic AMOLED" displays with HDR10+ support and "dynamic tone mapping" technology. The displays have curved sides that slope over the horizontal edges of the device. Unlike previous Samsung phones, their front-facing cameras occupy a rounded cut-out near the top-right of the display, and both models use an ultrasonic in-screen fingerprint reader. While providing better performance over the optical in-screen fingerprint readers introduced by other recent phones, they are not compatible with all screen protectors. Due to this, the S10 and S10+ are both supplied with a pre-installed plastic screen protector.
