Review on LK Ultrasonic Fingerprint Compatible Anti Scratch by Joshua Albright

They're simple, just watch the YouTube video for instructions and make sure you spend a minute or two with a good light source to make sure that all dust particles and stains are removed . from the screen (as with all screen protectors). If it takes you less than a minute to clear your screen, then you're doing it wrong. The key is preparation. - Fingerprint scanner still works Cons: - Edges can be a bit sharp, especially when not using a case - Oleophobic coating is quite weak and smears - Due to the burial method, there will always be a crease mark in the center (this is probably the biggest minus) Overall probably the best glassless screen protector for the s20 i have ordered 3 times. Most low stars go to low IQ people who cannot follow instructions properly. Suggestions for improvement: Find a way to remove the center crease, improve the performance of the oleophobic coating, and smooth out the edges for a 5-star product.
