MAGIC JOHN 2 Pack for Samsung Galaxy S21 Ultra Screen Protector [Ceramic Film Material Not Glass] 6.8 inch,[100% Fingerprint ID Compatible] Easy Installation Tray, Shock-Resistant, 3D Curved, Bubble

Extremely easy to install, no problems with my finger prints and no bubbles. I can't think of any reason anyone would rate this less than 5 stars.

I normally don't leave review unless the product is exceptional. YOU MUST WATCH THE VIDEO.. Make sure you clean your screen with the wet wipe and then dry your screen off fully, then tap your screen with the sticker (lint remover) even if YOU don't see lint, it doesn't hurt to take 1 minute to make sure. You'll want to do the cleaning and drying IN THE INSTALLATION FRAME. This way you don't need to touch the phone after its clean. I know some of you aren't the sharpest knife. Once you have the phone screen cleaned, watch the video and follow the instructions. Watch the video TWICE so you don't miss anything. If this screen protector gets a complaint, it should def not be on installation. and its crystal clear once its on. It also lines up PERFECTLY with my case. I don't know the durability as i literally just put it on, but otherwise i wish all screen protectors were like this one. Pay attention to the TOP of the installation frame, and install the BOTTON holes on first, otherwise it wont go on the frame. UPDATE: I have a hard time with my finger print reader now. I even reset the finger print and still it hasa hard to reading it. After a few tries, it may get it. (that saddens me)

On the surface, this looks like a great screen protector. The installation was straightforward and easy. I used the included QR code to watch the video and followed all of the steps. Doing this made sure it was perfectly position...and had tons of bubbles. I couldn't get the bubbles out, I have no idea why. My phone is a replacement / refurb for my S21 Ultra that went swimming accidentally, but the refurb unit had a brand new screen. This came with two screen protectors. The first one I tried to install never fully bonded with the side of the S21 screen and was visibly peeling off the entire left side. I removed it and tried the second one, and got tons of bubbles, but it appears to be holding onto the sides this time around. That said, given the rigidity of the screen, getting the bubbles to move out to the sides was basically impossible no matter what the video says. I'll be switching to a different protector because the bubbles just bother me incessantly.

These protectors are THICK. They are 2-3x thicker than any other screen protectors I have used. The first set did NOT install as easily as shown in the seller's video, and I had MASSIVE air bubbles and air pockets all over the phone screen. This happened with both protectors. The seller sent a replacement set, and this time I only aligned the bottom holes on the screen protector with the included green installation case. I held the top portion of the Magic John protector as I slowly used the included squeegee to work the screen protector from the bottom to the top. The new protector went on and looks good and works well. You CANNOT allow the Magic John screen protector to touch your phone screen during the initial application, you HAVE to only allow the bottom to touch the screen, and then work it towards the top. The touch sensitivity is as though the phone doesn't have the protector on it. Value for money is yet to be determined as opposed to a thinner protective screen from other sellers. I have used Magic John protectors on a S25+ and that one is holding up fine. For best color and clarity on your phone, these protectors should be replaced once a year, as they tend to yellow with UV from sunlight, as they all do.

This was an easy installation and there were no bubbles left over. It fits the edge of an S21 Ultra nicely and blends in perfectly with my Otterbox Symmetry cover. But, even though I had fingerprint security all set up, it wouldn't work after installation whether I had sensitivity set to high or normal. And, I was not able to add new fingerprints until I had been trying for some time. So, I am tempted to conclude that the material density is not good for the ultrasonic fingerprint detection. Now using face detect wherever that will work. I did finally get fingerprint detection to work by adding another fingerprint.

Great quality for soft screen cover!! Magic john has the best quality product

Love these screen savers. A bit tricky to get on but last a long time. Saved my screen from a couple cratches. A+

Not what I thought it was, took some of the minor scratches off my screen but did not fix and fill in like it claims. Very disappointed. For a cheap protector that might last you a month or less it works. You'll then be disappointed by it's low quality and how easily it's disphormed by little things. Relatively easy installation, very very thin, decently sticky to fit the screen well. Wouldn't really recommend.

Las huellas dactilares si se quedan marcadas en la pantalla y no se limpian tan facilmente.

Returned this as I no longer have the phone
