Only fools repeat the same actions hoping for different results.Coming from a bitten apple, I have tried soooo many (!) tempered glass screen protectors which pretended to do what they barely did:protect your glass screen and avoid wasting thousands of dollars.that was before actually finding any that would work with the fingerprint sensor of the S24 Ultra. The S23 Ultra was a nightmare to find one that would work with its curvy display.We know how S24 Ultra is pricey and changing a broken glass screen could sometimes cost a kidney.I am not a foolish man and yes, I do want my phone to last as long as possible. As yours, right?!!But let me focus on this review which caught your interest.I have watched a ton of Youtube videos and saved you time for doing the same thing.I also have done extensive research and unfortunatelly contributed to the pollution.But I did find those amFilm tempered glass screen protectors which I intend to keep as long as possible.Do they work? Yes.Are they perfect? Really close.Was I paid to write this review? Of course NO!Yes, I am confident to say that hey work!!!I've been very impressed by how easy the installation of the protective glass screen is. So far, it was the easiest one I found in more than 10 years of try and fail.Installation guideThere is a video which you can access with a QR code. Please, watch it. If you do so, you will be thankfull. If not...then it's hope to you.I litteraly took less than 3 minutes:- after cleaning the screen with the microfiber wipes, simply pick up the tempered glass, peel off the protective film, align the tempered glass, slide your finger along the middle of the screen and retouch.Done!Built qualityWhat impresses me so far is the built quality of the screen and the fact that the tempered glass screen is perfectly aligned with the S24 Ultra screen. There is even a cut hole for the front camera, which you don't find on other traditional tempered glass screen protectors.I,VEbeen using my Ultra with the amFilm glass screen since it came out and the built quality is really outstanding!I also love the fact that after many usages, you barely see any finger marks on them.Yes you will lose the anti reflectiveness of the S24 Ultra (which is made of Gorilla Glass Armor) BUT you will appreciate the fact that you don't have to wipe your phone's screen for dirt every hour ;)I also have no problem using them with a protective case since the screen protector is solid but thin.Customer service and value for moneyRegarding their customer service, it is also excellent and I did try to reach them since one of the two tempered glass screen protectors came without the adhesive. They simply reimbursed my purchase.I loved the screen protector so much that I even bought the same for my iPhone 13 Pro Max.Since it comes with 2 packs and even 2 camera tempered film protectors, the value for money is perfect.
