According to Gizbot, tipster Ice Universe has suggested on his Twitter account that Samsung is planning to completely let go of the iris scanner that has been present in its all flagship smartphones since it launched the Galaxy S8. Instead the South Korean technology giant is going for an ultrasonic in-display fingerprint scanner which will cover at least 30% display of the upcoming galaxy S10 smartphone. So, there will be a much larger area on display where users can place their finger to unlock the device.
— Ice universe (@UniverseIce) November 2, 2018 It is worth noticing that ultrasonic fingerprint sensors are not the same as the ones used in various devices from Oppo and Vivo we have seen recently. Smartphones from Oppo and Vivo and the recently launched OnePlus 6T sport an optical fingerprint sensor. To highlight the difference between the two, ultrasonic fingerprint scanners use ultrasonic pulse against the finger to map its pores and ridges and then uses it to detect the fingerprint. An optical fingerprint sensor, on the other hand, uses light to illuminate the pores and ridges on your finger and then maps it. On being compared, ultrasonic fingerprint scanners are more accurate and work faster. This is because sound is able to create an in-depth 3D map of the user’s fingerprint and the technology used by optical fingerprint sensors can only make a 2D scan of the fingerprint. This is the reason why optical fingerprint sensors don’t work well when your fingers are dirty or moist. We are really looking forward to see how the fingerprint sensor of Samsung Galaxy S10 performs and we already like the fact that the technology company is dedicating 30% of the screen to the fingerprint scanner alone. We would have to wait till the launch next year to know more about it and till then, we’ll keep you updated with whatever we know.
