You don’t get many good tempered glass screen protectors for phones with curved screens and under-display fingerprint scanners. Fortunately, amFilm has you covered if you’re looking for one for the Galaxy S20. This glass screen guard works with the ultrasonic scanner, but you have to go through the setup process again. It’s applied to the phone by adhesive cured by UV light. It’s expensive, but worth it for the protection it offers.
A smart film screen protector isn’t quite as durable as a tempered glass one, but it’s easy to apply and usually a bit more affordable. A special UV treatment prevents the film from yellowing as well. Touch sensitivity and display clarity won’t be problems with these ultra-thin screen protectors and they will also work with the ultrasonic fingerprint scanner. The IQ Shield smart film protector comes in a pack of three.
The Armorsuit Militaryshield is another excellent TPU film screen protector for the Galaxy S20. It’s ultra-clear and extremely thin, so display clarity, touch sensitivity, and using the fingerprint sensor won’t be problematic. You get edge-to-edge protection, and a self-healing layer takes care of minor scratches and other blemishes.
Another TPU film screen guard to join this list is the Skinomi Techskin. If you don’t want to use a case, this option is ideal since it also comes with a film protector for the back glass panel of the phone. Both pieces of film help keep scratches away and come with a self-healing layer to fix minor blemishes. It’s also resistant to punctures and UV light and will not yellow over time.
