LK[2+2 Pack] Designed for Samsung Galaxy S10 6.1inch, 2 Pack Flexible TPU Screen Protector and 2 Pack Camera Lens Protector [Ultrasonic Fingerprint Support] HD Clear Easy Installation

So I accidentally dropped my new S10 into the sink, and ended up with two semi-punctures to the factory Samsung screen protector film. There already was another self-induced blemish elsewhere on the film so it was clear a new protector of some type was required. Reading comments and reviews I ended up buying two film-sheet type products (one of which was this LK, and the other of which was from Olixar) and two glass-type products (one of which was from Semriver and the other of which was the expensive Dome one from Whitestone). I decided to try the highly rated LK first.And BOY... IS IT GOOD! In my opinion it's superior to the factory Samsung film.A few plays of the install video made it quite clear how it was to be applied, so I was confident. But the first attempt was less than perfect. Thankfully there are three sheets included in the box because the first attempt left some small bubbles in the middle of the screen which were simply impossible to "push out". Obviously I was a bit too casual with the step that places the multi-tab sheet over the glass with alignment required before pressing down and applying the squeegee. I thought I was careful but clearly not.So I peeled off the first sheet and started all again with a second one, this time being much more careful about aligning, pressing down, and then squeegeeing being sure that there were zero bubbles visible through the paper before performing the final application steps of removing the paper from the film and applying final squeegee steps.In the end, it was 99% perfect and bubble-free. There were just a few minor small bubbles near the edges which were easy to push out with my thumbs so that it was now 100% perfect. The hole for the camera is perfectly sized and aligned, and the film is perfectly sized to cover the entire glass below. I was concerned about possible compatibility with my Otterbox Defender case, but my concerns were groundless. The Defender case applied perfectly with zero puckering of the edges of the LK sheet (unlike with my experience applying the Defender with the factory Samsung sheet, because I didn't pay attention and do the Defender install properly).Furthermore I was concerned about how the S10 fingerprint reader would work through this LK film, and I'm thrilled to report IT SEEMS SUPERIOR TO HOW IT WORKED WITH THE FACTORY SAMSUNG SHEET! I had lots of trouble registering my two fingerprints when I got the S10 (lots of "press harder" requests) but now that I've replace the screen film with this LK product I was amazed at how easy and totally problem-free the re-registration process went this time.I also was concerned about how clear and transparent the LK sheet would be, and to me it could actually be clearer than the factory Samung sheet. Regardless, it is certainly smooth and shiny and blemish-free and perfect. I couldn't be happier with how it looks.For sure it seems that finger scrolling and tapping is much more accurate and responsive than it was with the factory Samsung sheet. I'm amazed. The sheet+glass certainly seems much more responsive to my finger tip actions. This was totally unexpected. I didn't know if the friction-feel of the sheet would be smooth or rubbery or matte or what, but it turns out to be just perfect. Invisible to the touch. It's like I'm moving my finger across glass.So I still have one more LK sheet now in reserve, if/when I ever need to replace the one I just applied sometime in the future. And I have the other products I also bought (and will keep rather than return), in case I decide to try one of them sometime in the future when the need arises.But for now I really can't overstate how happy I am with this LK sheet. Fingerprint reader and camera (through a perfectly aligned hole in the LK film) all work 100% perfectly. And application is really easy.One more plus: looking at the screen while wearing polarized sunglasses while in my car no longer is a problem. The phone screen is now visible bright and colorful through the LK sheet, unlike how it was with the Samsung factory film. Obviously there must be a molecular structure difference in the material used in the LK film which causes light passing through from the phone screen to "align" better when viewed through the polarized sunglasses, allowing light to be more easily visible through the LK film.

Goes on beautifully! The process ensures zero bubbles and perfect alignment. Fits perfectly. Biometrics work great, unlike another brand I bought.

The installation process was easy to do although alignment was a little cumbersome with all the extra tabs hanging off the bottom. Also paying attention to the cutouts for the speaker and the camera was good enough to get it aligned properly. For some reason the corners aren't adhering perfectly on mine but I also have a case which may be pealing it up. I don't know how scratch resistant the protector is yet as I've only had it on for a day but its been in my pocket all day and its still looking great. The surface of the screen protector is smooth with only very minor wavy/dot texture in a few spots (small spots <1mm in size). I can only see the texture by reflecting a bright light off the screen with the display off and looking at it very close up. The only visible surface imperfection I can see from far away (with the screen off and a bright light reflecting off it) is a horizontal fold going across the center of the screen protector. You can just barely see it with the screen on and bright light reflecting off it if you are close enough. The artifacts aren't noticeable when using the phone normally. Fingerprints on the other hand are clearly visible with the screen on even with no external light reflecting off the display. I don't remember how oleophobic the original screen protector was but this one doesn't resist fingerprints at all. When watching movies I have to wipe the screen first or it will drive me crazy. The fingerprint reader has actually improved in accuracy and speed compared to the stock screen protector. I didn't have to delete and redo my fingerprints either, it all worked right away. I think its because this screen protector is much thinner than the original one that came with the phone. Overall I'm pretty happy with the quality for the price I paid. I would really like it to have some oleophobic coating on it even if it did cost a bit more. Anyone buying this should remember that its not tempered glass and is very thin. It will probably do pretty well stopping small surface scratches from being in a pocket with keys and other minor scrapes. It will definitely not stop any direct hits from going through and scratching your screen, its just not thick enough. Even the original screen protector wasn't thick enough to stop any hard direct hits from damaging the glass underneath (it didn't for me, dropped from hip height onto concrete with small rocks/gravel on it). If you want protection from direct impacts you will want to go with tempered glass and not these thin protectors.
