amFilmUltra Screen Protector for Galaxy S10, UV Gel Application, Tempered Glass, Compatible with UltraSonic Fingerprint Scanner for Galaxy S10 (2019), 2 Pack

I have installed about 15 tempered glass screen protectors on various phones (most were successful however a couple not so much) but this is the first time using a curable adhesive so I was a bit apprehensive but since it was a necessary evil I carried on.I watched quite a few videos and looked at a bunch of options for the S10. I absolutely wanted to have a tempered glass solution instead of a silly film. So because of the fingerprint scanning feature below the glass, it appeared I had to install a curable adhesive solution. So after reviewing a bunch of vendors, I landed on this one because it was moderately priced, appeared to have better reviews than most, and better product support than some of the other options.With all that being said, I was a little worried about the install process. Once the product arrived, I set aside about 30 minutes of uninterrupted time to ensure I could focus on the task. In the end, it was surprisingly painless and really was not as complicated as so many people were complaining about. I have to admit I was probably more prepared than most since I watched about 5 different videos around this process so that I wasn't surprised by any of the steps. I followed the instructions listed on the included piece of paper to the letter even though some of the videos mildly contradicted them. The final result is exactly as I would have expected and it looks great. I had no bubbles or dust on the main screen, however even after careful inspection I did notice 1 bubble that I didn’t even see until the next day by the camera along the edge. Upon reflection, I am not surprised because this area of the glass took the longest to spread to. I had to wait like 5 minutes to ensure it was fully distributed but it was most likely a result of me slightly tilted the phone away from that area while I was pulling out the tab that dropped the glass onto the adhesive. This caused the glass to make contact with the adhesive slightly off-center with the dollop of adhesive being closer to the bottom. I am really anal about having anomalies on my screen protectors and luckily I can’t even see it when looking directly at the phone since it is located on the curved part of the glass and is barely noticeable.The only slightly annoying aspect of the install was cleaning up some of the residual "gummy" glue that was around the edges of the glass. It literally had the consistency of little boogers in various spots around the edge of the phone. It did not require the use of mineral spirits or cleaning compounds that people indicated (maybe because I had completed the full cure process before trying to clean it up... idk). I was able to easily clean it up with the included wet/dry wipes. I assume that is going to be required regardless of the vendor due to the nature of this style of installation and the fact that you should expect some seepage if you have achieved full glass coverage.In summary, I am very happy with the product. The install process was not overly complicated and/or difficult to perform. The price was competitive based on the other products out there and the quality of the result met my expectations. The swiping functions work flawlessly and in the end, the fingerprint scanner works. To be honest, I didn’t even set it up before adding the glass since I don’t use it (I use facial recognition, pins, and trusted locations). I just set it up in order to confirm that it worked prior to writing this review. Therefore, I don’t know if I need to press slightly harder now than I would have prior to the installation but it does work just fine with just a light pressure touch. If you have the time and patience to ensure a quality install I would recommend this product to others looking to better protect their S10 phones.

Update 4/9/21: The screen protector breaks easily... but then again, so do these damn infinity edge displays or whatever they're called. Better than a screen replacement for sure. Once it had a small crack, it slowly spread throughout the protector until it was pretty much a cobweb. The screen underneath was untouched and the protector lifted off in one clean piece.I didn't drop the phone, by the way; the first crack was from my belt buckle - never had that happen before! I think the cushion of glue underneath is mostly good, with a few cons; it absorbs impacts and keep the screen underneath safe, as well as binding the protector together when it breaks so you don't end up with little bits of broken glass everywhere, scratching you or the screen. On the other hand, it seems to cause the protector itself to break more quickly because the glass is brittle and the cushion beneath it allows it to flex under pressure and crack. Once the first crack was there, I saw new cracks pop up just because I used the fingerprint sensor.Anyways, it's definitely real glass; it can't be scratched by steel, not even a box cutter. I'll be putting the second one on today.--------I'm pretty impressed so far. I'll have to drop it a few times and report back, but the screen quality looks crystal clear through the screen protector, the fingerprint reader still worked even without re-registering it, and it really wasn't that difficult to install.I do have a very small pocket on the lower left edge where the adhesive never reached, but that was likely my fault- I didn't have the protector aligned perfectly the first time, so I had to slide it up until the hole matched the front camera. It only took about 10 mins to do the whole thing, and I had no difficulty with dust in a freshly-showered-in bathroom.The video on their website clarified the installation process very well, and I'm glad I watched it before I started. The UV light is pretty damn nifty - the glue turns into a gel-like cushion underneath the protector, which will hopefully be a little extra protection.The protector does not reach all corners of the screen, which is part of why I misaligned it the first time. This makes it compatible with my case, but makes the edges slightly more vulnerable - every crack I've ever gotten on a Galaxy has been a spiderweb-style crack directly on the edge. On the other hand, this is the only screen protector I've ever had that 1) looks good, 2) feels good, 3) still permits the fingerprint sensor and 4) works with a case. Hopefully it will do the job next time I have a clumsy moment. In spite of the instructions, I decided to leave the factory-installed screen protector on and install this one directly on top, and had no issues doing so.
