Does the Galaxy S20 fingerprint scanner work with screen protectors?

This technology was a bit problematic when the Galaxy S10 phones were launched. Samsung was forced to release a software patch for those phones shortly after they went on sale to improve the speed and use of the scanner. This largely solved the problem, and Samsung continued to use the technology. Now Samsung’s in-display fingerprint readers are among the best, and they perform amazingly with little to no issues. Does the Galaxy S20 fingerprint scanner work with a screen protector, though?

Will the Galaxy S20 fingerprint sensor work with a screen protector?

However, that answer might change if you use a tempered glass-based screen protector. These offer more protection for your display than plastic or film. At the same time, some tempered glass-based products can mess with the ultrasonic tech in the fingerprint sensor. In general, the thinner the tempered glass screen protector is, the better it will work with the Galaxy S20 fingerprint scanner.

One way to stay safe is to be on the lookout for product descriptions and titles. Many of these screen protector manufacturers advertise compatibility with the fingerprint sensor. One example is the Letang Galaxy S20 Screen Protector two-pack. It’s affordable, resistant, and works with fingerprint unlock.
