How to Add a Fingerprint on Samsung Galaxy A20 Device

Keeping your smartphone safe from unauthorized usage is now made easier using your fingerprints. Yes, you heard it right. In-print fingerprint sensors can now be found on modern smartphones like Galaxy A20. While some opt to use PIN or passwords to lock their respective devices, fingerprint protection is deemed an ideal screen protection as this can’t be hacked easily. Thus, safer  than password, PIN or pattern. Before we will teach you how to add a fingerprint on your Galaxy A20, let us first understand how this fingerprint sensor works on smartphones.

In-screen fingerprint sensors on smartphones can be both ultrasonic or optical. The latter works by projecting the light in which the image of your fingerprint will be captured in the area of the in-screen scanner based on the light being reflected from the space between the phone display’s pixels. 

So the first thing you need to do before using this biometric protection is to add your fingerprint on your device. The procedure is not that tricky at all. But if you are not that familiar with how it’s done, here’s the walkthrough that you can refer to.
