[2+2 Pack] Screen Protector for Samsung Galaxy S21 Ultra/S21 Ultra 5G, 9H Tempered Glass, Ultrasonic Fingerprint Compatible,3D Curved, HD Clear,Bubble-Free for Galaxy S21 Ultra Glass Protector

The package for the Samsung Galaxy Note 20 Ultra contains two front screen protectors, two camera protectors, two wipe sets, and two installation sticker sets. I have only installed and used the front screen protectors. I have not installed the camera protector but I will make a comment about it later on.The front screen protector is clear and covers the front-facing camera. The pictures taken with the front-facing camera are clear and colors appear to remain true. Colors in different applications, remain true. The screen is response across the entire surface, including edges for applications from email to games.It is typical that after installation of a new protector the fingerprint scanner will need to be retrained. As the instructions state, you need to have settings set to allow for more sensitivity. This is also typical. My fingerprint scanner settings still worked right after installation. I trained an additional finger scan with no issues. If you find you have to press extremely hard to train the scan, there is an issue. You typically have to press as hard for normal use as you do for training to get it to work correctly.My concerns with this product lie with installation instructions and package contents. This kit does not contain a box to align the screen during installation. That is fine. What it does contain are two guide stickers. I prefer this as it amounts to less waste after installation is complete. However, the instructions say nothing about about how to use the guide stickers. Luckily, there are videos online if you need them. In sum, it amounts to setting up the guide stickers as hinges, removing the protective backing, and then folding the screen protector onto the screen. But there are some hints and tricks that you find online, such as turning on your screen beforehand to use the backlight and ensure things like the camera are properly aligned as you set the guide stickers. Also, in the video I saw, there was a third sticker to use to fold the protector over on the guide sticker hinges. this helps ensure that you do not accidentally touch the "clean" side that must adhere. I suggest you use the dust-absorber sticker for this. I am also disappointed that there are only two sets of wipes and installation stickers. I suggest the supplier consider four. Like myself, I am not installing the front and back protectors simultaneously. Even if this is your first cover, the likelihood of both the front and back breaking at the same time and requiring replacement of the second set of protectors simultaneously is unlikely. Thus, additional installation cleaning and support sets should be provided.As stated at the beginning, I did not install the camera lens protector supplied with the kit. I already had one installed. The camera lens protector supplied has two cut outs. One for the IR range sensor and one for the flash. The issue is that in plastic and/or less-than-very-clear glass protectors, the flash will actually reflect in the protector and obscure the image. So, the cutouts prevent this. However, it means that the IR sensor and flash areas are exposed to damage. My current protector is a finer glass and has no cutouts. I have no issues with flash reflection. This leads me to suspect that the camera lens protector in this set is likely of lesser quality. How might that impact images? I have no idea. I would be willing to try these camera lens protectors in a pinch. But would only likely keep them on until a high-quality full (no cut out) replacement arrived.UPDATE: About two weeks after installing the front protector, the phone fell about a foot. The front protector just fell off. I reapplied it but had to retrain fingerprints.I also applied the rear camera protector. For the IR range sensor and flash, there is a cutout. I assume this is so that the light does not refract and reflect in the cheaper quality protector and blind the lenses. While the protector was properly adhered, the camera image quality from all three lenses appeared normal. Within a week of applying the camera protector, it began to lift on the edges. The adhesive whitened. Pressing it back down did nothing and now images are distorted depending on what lens is used nearest various lifted edges. In sum, this product has an adhesive problem with both front and back protectors.

It looks like most of the reviews for this product are for an iPhone screen protector. This review is for the Pixel 6 Pro version, and most of the reviews for this product aren't applicable to the Pixel 6 Pro, thanks to the in-screen fingerprint reader and the curved glass on the Pixel 6 Pro.These screen protectors are ALMOST great. Installation was pretty straightforward: there's no included frame or anything else to help align the protector, but using the cutout for the pinhole camera at the top of the screen as a guide will get you close enough. As with all of these screen protectors, patience is key as any speck of dust will leave you with bubbles. Make sure your screen is perfectly clean before installation. The kit does include a wet cloth and dust removal stickers but no microfiber cloth, which is pretty standard for these products. I managed to get an almost-perfect installation on the first go. The glass is quite clear, and, at first blush, it's not obvious that there's a screen protector installed. Nice!The huge downside - and the reason for the 3 stars - is that it seems like the manufacturer couldn't figure out how to preserve the function of the fingerprint reader with the material they used and did something different to the glass in the area that covers the fingerprint reader. Unfortunately, this area is extremely visible and obvious and, in the protector I installed, left a huge bubble. Even after leaving the protector on the screen for some time, the bubble remained. The fingerprint reader's functionality was severely limited, even after I re-registered my fingerprints: the phone failed to recognize my fingerprint more times than not. A second installation may have fixed this, but I was so put-off by the horrible look that I took off the screen protector and didn't bother with a second attempt.The protector for the camera bar is quite nice, and I did end up leaving this installed. Most Pixel 6 Pro cases don't fully protect the camera bar, leaving the bar vulnerable to damage and scratching, so this was a nice way to flush out the protection for my phone using one of these cases. Even though I didn't end up using the screen protectors, the protectors for the camera bar made the cost of the product worth it for me.For $15 for two sets, the value of these protectors is good. If you can get past the less-than-perfect look and reduced functionality of the fingerprint reader, this is an excellent buy. I ultimately went back to the tried and true Whitestone Dome Glass screen protectors - which I had used several of before - that are also available on Amazon but for more than 3 times the price. Those protectors, though, result in a truly invisible installation and fully preserve the function of the fingerprint reader. I'd recommend those for a flawless, invisible look as these ones don't get that done.
