Review on IQ Shield Screen Protector for Samsung Galaxy S21 (6.2 inch) - 3 Pack, Case Friendly with Fingerprint Scanner, Anti-Bubble Clear Film by Leslie Williams

My experience with this product has shown that it is easy to assemble. First I read the instructions. Then I followed them to the letter. Everything got very wet and I was afraid that something might go wrong, but to my great surprise I was able to get the screen protector right on the first try. After squeezing out excess moisture, I let my phone sit for an hour before trying to put a case on it. To my satisfaction, the cover went up very easily and none of the edges lifted. It's been running for a week now and it's still stuck to the screen. My biggest concern is that the fingerprint scanner isn't working. First I found that only one finger could be read. So I tried to re-enroll other fingerprints and only one of them was successfully enrolled. So after registering one finger for each hand, I gave up the rest. However, I have to say that even with a high screen sensitivity, I have to knead the glass with my finger to make it work. It also reduces screen sensitivity when using hand gestures. It doesn't bother me too much, but it may be annoying to others. I find using my index finger and pressing down firmly and then moving it achieves the correct movement across the screen. Given the results of the on-screen test results, losing some responsiveness is worth it to me if there is some anti-shatter protection. Durability from CNET.
