LK 3 Pack Screen Protector Compatible for Samsung Galaxy S21 Plus, Positioning Tool, in-Display Fingerprint Support, Maximum Coverage, Flexible TPU Film

Very good screen protector. It fit phone good. Good price point. Held up real good. Free of fingerprints. Did not get dust in the phone.

Over the last decade, I've owned nearly every Samsung Galaxy phone, including this year's S21 Plus. For much of that time, I've grown into a loyal LK brand TPU screen protector fanatic. The TPU films by LK were the only ones that ever worked like a charm on my Samsung phones with curved edges, so, of course, using them with a flat screen, like that of the S21 Plus, is no problem.Anyway, I received yet another pack of 3 from Amazon today, for my new S21. I'm so familiar with this kind of screen protector, that a flawless installation took me less than a minute, and I'm typing this review with a fresh one on my phone right now. The LK TPU films are VERY long-lasting on my devices. Because I'm so meticulous about cleaning my phone and wiping the screen down, REALLY taking great care of it, a single LK film typically stays on my phone around 9-10 months before there's any noticable wear. Therefore, this pack of 3 will last longer than I plan on having this phone, since I upgrade at or close to the 2-year mark. Even when I'm a little rougher with my phones, I'm still able to get a minimum of 6-7 months out of each LK screen protector. Other brands - more expensive, less expensive, or equal in price - just aren't as good. (And trust me, I've tried all the usual brands you find on Amazon, in the first couple pages of results.)While it's true that TPU just doesn't feel as smooth to touch as tempered glass, or the Gorilla Glass that your screen is made of, if you plan on using your phone or tablet's on-screen fingerprint sensor AND want the added protection, TPU is the way to go. Specifically, LK's TPU. (Tempered glass screen protectors rarely work as intended with fingerprint sensors; sadly, even those that LK makes. Even if your device has a flat screen. I know this, because in the 8 days that I have now owned this flat S21+, I decided to try my luck with LK's glass, even though I knew what would or could happen, and just like all other phones and sensors and tempered glass protectors that came before that one, glass protectors and on-screen fingerprint sensors, in general, just are not meant to be. They're not compatible, and that's that.)Obviously, I will continue buying this type and this brand as long as the company makes them.

A couple of tips regarding installation.1. Make absolutely sure you watch the correct video for the version ordered. I made that mistake and after the first couple steps realized something was wrong. Wasted one screen protector.2. In the end it was a bit off centered to camera. Might be useful to turn the display on while lining it up during the applicable step.3. There's a very faint crease in the middle where the green stripe was. Not sure if this was a result of pressing it down too hard when first putting the screen protector on the phone. It's not at all noticeable unless looking for it but next time I'll try not to press too hard.4. This is probably the most important thing. There is no guarantee that the side you first stick to the phone is dust free. So when it comes time to squeegee the first half permanently, while it is lifted off the display., use the dust sticker to remove any remaining dust. Repeat for the second half.Overall it's a great protector. Not sure if it will offer as much protection as glass but the surface is smooth, installation was relatively easy and the fingerprint sensor works flawlessly. For anyone with an ultrasonic sensor like the s21 series, I highly recommend a this product.

This Screensaver had a method of install I had never seen before that actually lined it up perfectly , it was the perfect size for my screen, and there were NO bubbles under the protector. I had to watch the video, but it was totally worth it. The fingerprint reader works perfectly. I did not even have to re enter my fingerprint. I am so happy. This was the best Screensaver install ever.

I bought this for my galaxy s21. This is the 3rd or 4th of this brand I have purchased and have never been disappointed. They are easy to apply with video, looks great, clear, and fit perfectly. Great value because you get three to a package. They are durable and easy to clean.

It took me two tries to get this on. I followed the instructions because they looked pretty simple. Nope, film folded over and I've wasted my first one because now it won't go on smoothly. I gave up before I threw it in the garbage and will try again tomorrow. I tried again today and got it on...finally. it's a nice product if you can get it on with no bumps.

This product is not only useless as a cell phone screen protector, it's a first class frustration machine! You will almost need to be a seasoned contortionist and a mind reader to ever have a chance of installing it correctly the first time. I now understand why they come three in a pack. You will absolutely destroy the first two just trying to follow those ridiculous installation instructions. Then, even if you're lucky enough to get the last one pressed on the cellphone face correctly, the gooey plastic protector will surprisingly begin to slowly slide out of place, making the whole endeavor nothing more than a horrific waste of time and money. I only wish there was a "minus star" category in the rating evaluation. If not, this item should seriously merit consideration of one.
