SMARTDEVIL[3 Pack] for Samsung Galaxy S21 Screen Protector, Finger Print Reader Compatible, Fast & Easy Installation, Clear 9H Tempered Glass Film, Alignment Frame [Dust-Free & Bubble-Free]

The best thing with this screen protector is how it is applied. It is super easy and extremely smooth process with very high success rate.After application your fingerprint scanner doesn't work at the beginning and I assume that it changes the reading profile a little bit. But after the application, I did delete the old fingerprints and registered them again. And the fingerprint scanner is working very smooth now.As far as I see the screen doesn't effect the S Pen sensitivity and everything functions smoothly.To be honest I am very satisfied but to be fair and honest I also want to mention two very small down sides !1- I use Otterbox Defender, it collides with Defender at the bottom left side. As a result the screen protector is popping up from there for may be 0.3 inches. To be honest it is not a very bad thing but I could still manage to fix it that I left the phone out of the case for the night and then put the case and the problem seems to be solved !2- The package comes with 3 screen protector and you will have to put the new protector into the application frame ! That part is a bit tricky and I mistakenly removed one of the protector layers out of the protector.But overall, I am EXTREMELY HAPPY with this product and advice to everyone.

This comes with THREE glass screen protector, accessories to wipe, clean and remove dust and a special case to align the screen to the phone.One needs to read the instructions carefully before starting this. And instructions are easy to understand and there are number of each packets/steps as you can see in the pictures.After properly following instructions - there were three large bubbles on the screen with careful rubbing them to side they disappeared - we thought all good.However - as we tried to install the case - the bottom edge of the screen protector popped up (as seen in the picture). No matter how many times we tried - it would always popped up. Looking closely - the screen was slightly poking out at the bottom. Since we used the applicator case that came with it - I have a believe that either that has a manufacturing defect or we did not place is perfectly on the phone.In any case - other than trying with another screen (since it came with 3) - we thought we didn't have any other option. Before doing that - I figured lets just lift this up and move it up a bit and put it down. So I took the entire screen off by the edges and very slightly moved it up and put it down. (One can not push it up when it is fully down - so we had to lift it up fully and then align it by hand. Surprisingly - it laid down perfectly this time and simply pushed out the bubbles itself. Installing the case this time did not create any problems. So we are happy with the screen protector and it is not visible at all. If this did not work, I would have rated it as 3 start but given that we managed to fix it - I am rating it as 4 stars.Fingerprint recognition works after re-scanning.

makes screen protector install easy. screen protector seems like any other. has survived a couple 4 foot drops

This is by far the best screen protector I've purchased. The instructions are easy to follow, installation was quick and setting up the fingerprint security was a breeze. I highly recommend this screen protector!!

It installs just a tad too low and wasted a whole protector only to find out it has rendered all fingerprint scanning useless and works maybe 1 out of 8 times.

Very happy with the result highly recommend

This kit is a great way to protect your high dollar Samsung s22 screen and is pretty much idiot proof in the installation process. The kit came well packaged with well laid out instructions on how to install included with the spare screen protectors. It is a big improvement on the old way of having to manually install them by trying to align protector without getting air bubbles or lint between screen and glass. This one comes with a jig that fits perfectly over the phone while peeling back protective film and letting the glass settle into place automatically lint free. The kit comes with everything needed for install including wipes for cleaning screen. The only thing I would improve is the sticky wipe to remove lint was a little too sticky which resulted in some glue transfer onto phone screen which required me to start the cleaning sequence over to the wet wipes. The jig made it possible for the screen protector to be centered on phone perfectly without any input from me. The protector is a perfect size and left a slight margin around edge to not interfere with phone case and the edges of protector have a smooth rounded edge so the transition from screen to protector is virtually unnoticeable by feel.The only thing I noticed after install is the fingerprint scanner wouldn't pick up my print until I added new prints to phone security screen after install and set phone to high sensitivity to read with protector on. I did have slight micro-scratches on the oem screen that I tried buffing out with car polish, but they were impossible to remove as the scratches remained if held at an angle in certain light. After the screen protector was installed, I can not see any of the scratches no matter how hard I try. I also noticed that this screen protector doesn't smudge up with fingerprints as bad as the oem screen and is easier to clean. There is no response issues with the screen protector installed except for the fingerprint scanner mentioned above until I rescanned my prints then it worked as normal. I haven't tested the durability of the protector and hope I never have to, but it is nice knowing the kit came with 2 more protectors just in case.If you need a screen protector for your s22 or tired of looking at minor scratches on your oem screen then give this kit a try. For the price and simplicity of the install, you can't go wrong with this kit. Well worth it in my honest opinion.

Following the instructions I can't believe how well this worked.. Usually there is issues with the first screen causing you to trash that one before a good fit. This took all of 2 seconds. Great product!
