DeltaShieldScreen Protector for Samsung Galaxy S21 Ultra (6.8 inch)(3-Pack)(Slim Design for Cases)[Compatible with Fingerprint Scanner] Anti-Bubble Military-Grade Clear TPU Film

I've been using Deltashield screen protectors for the last two gen of phones, first purchase being for my S20 Ultra and now the S21 Ultra.The surface feel is not quite as slick as tempered glass screen protectors but for a TPU based film protector, surprisingly smooth feeling. Very scuff/scratch resistant. The self healing feature is just an inherent quality of the TPU material, but works well. Doesn't get all hazy and scuffed up after awhile like the hard plastic film protectors.The edges stick well so long as you give it an hour or so for the solution to dry out before trying to push the edges down. If you just squeegee down and then try to press the edges down on the curved screens while still wet/damp, the edges will tend to pop up again. I'd recommend squeegee the flat portion of the screen, press that out first, press the edges down a little initially to help squeeze out excess solution. Then wait for a bit, leave the phone alone. Make sure not to get dust or oil around the edges. Give it a good hour to let the solution around the edges to try a bit and press down the edges again. This worked well for me. No bubbles, no popped up edges, no issues with case install either.

I've been using these flexible screen protectors for years, so this one is as great as the other top brands, and I like that it's made in the US. Installation takes about 10 minutes, mainly waiting for the left and right sides to dry up enough to start sticking to the screen. The first time I used one of these wet-installation protectors, it took a bit of getting used to (watch the video to make sure you understand it), but since then I've installed about 10 screen protectors flawlessly-- just make sure to carefully center the protector to make sure it doesn't get in the way of the camera or the case if you put one on.The protector does get dings and scratches over time, but they slowly go away, so a year-old protector still looks good, at least for me.The Samsung I have has a behind-the-screen fingerprint sensor, which is slightly less sensitive after the installation. However, the screen sensitivity is still great.

Overall, quality is good, fingerprint sensor works great under these, the edges adhere well on the curve if you pay attention to them every 20-40 minutes for a few hours and make sure to keep them pressed down against the screen. Clarity is good, feels fine, aside from a minor amount of extra drag from the self-healing sort of material, compared to glass. Overall, though, they're great, especially for the price.These are good quality screen protectors, and for an amazing price. Unfortunately, I want very careful with my first one, and it was off center, got a little stretched, and got some lint under it. Figure I had 2 more shots, so why not try to get it perfect, instead.Immediately got lint on the edge of the second one and just could not get it off of there.So then, onto the 3rd one. Everything looked great. Was careful to try to avoid lint, got things centers the best I had so far, squeegee'd the water out, got the edges to lay down nice, kept checking them and ljshign them down... Everything looked great. Turned my phone on and BAM... lint, right in the middle... Lol.If it weren't for me doing this in a disty, dry house where there is a lot of stuff in the air, I'm sure this would have worked out great. They're soft, flexible plastic that go on fairly easy, and at this price, I don't mind ordering more to try a few more times until I finally get it right. I could try 20 times with these for the price of others, haha.

I had bought a way more expensive glass screen protector for my new Galaxy S21 Ultra, and after just hours, decided to return it, it was not touch screen friendly, I had to scan my finger numerous times, sometimes not even being able to unlock my phone successfully, it was easier to apply than this one though. But all of my other problems were changed for the better, no problems with the fingerprint scanner, touch reliability is the best and it protects my screen, plus it has more than one for the future. I have installed these before so I was familiar with the fact that the bezel on this phone (curved) would make it more difficult and time consuming than just placing a glass screen protector, but the end result is worth it, you have to spend more time on the bezels to get a perfect install, make sure to use your whole palm to hold it for a minute or two, and then be very careful with it until it cures completely, so install at night per the instructions. I do have a case that protects the bezels, but if you are a guy that sticks this phone in your pockets w/o a case, it will peel off because of the rubbing.

It never sticks properly around the curved edge of s21 ultra. Tried all three carefully following the instructions, but with no luck. I wouldn't recommend this one for S21 ultra or something that has curved edge. Besides due to edge always in a lifted situation, dust accumulated and bubble appears a lot. However, finger print and touch works fine.

I got this screen protector for free in exchange for a review, but all opinions are my own!First of all, the price point for this set is fantastic. I have purchased from this brand in the past and have never been unhappy with a purchase. This kit comes with three (3!) screen protectors, screen cleaning spray, a nice cleaning cloth, and a rubber tool to remove air bubbles. It has everything you need to keep your phone’s screen in pristine condition, plus it comes with installation instructions and a lifetime warranty! Signing up for the warranty is actually allowed me to receive the opportunity to try out this new product so I’m happy I did :)
