The Galaxy S10 sports one of the most advanced fingerprint sensors in a smartphone today. Using Qualcomm’s ultrasonic in-screen fingerprint technology, your Galaxy 10 device provides top tier security with ease.
Unlike the previous fingerprint scanners of older Galaxy models and other non-Samsung phones, the S10’s fingerprint sensor works by using sound waves being reflected from your skin. This makes it more effective in detecting your finger through grease, water, dust, lotion, or when there’s too much light. This high tech sensor can take a 3D image of your finger, detecting the valleys and ridges of your skin, in order to identify it. The way this works is by allowing the sensor to capture electrical signals from your skin when you touch the glass. The unique layout of your skin makes it easy for the sensor to recognize your finger.
In general, the ultrasonic fingerprint sensor is way better than the previous capacitive fingerprint sensor. What you must do first is to set it up so you can start using it on your device. If you’re wondering how to do that, follow the steps below.
These are the steps to begin adding your fingerprint on your Galaxy S10:
