Installation is as simple as possible and it fit perfectly edge to edge, so good that at first i thought that i made a mistake and didnt get the screen protector to stick to my screen with how invisible it is. Review: It's really good - and I'm not even an AI - I really hope this review doesn't get lost amongst all the rest of the reviews that are clearly written by, or with the help of, AI - because genuinely this is a really great product and I'd buy it again any time! I was switching from the old Samsung screen protector. This one was really easy to apply - stick the plastic guide in the USB-C port, hook the film over the posts, make sure your screen is clear of dust, and then apply one half then the other. There was a handy green sticky strip on the leading edge of the film backing that seemed to help scrape off any errant bits of dust that landed after cleaning. Do that twice, unhook off the plastic, then smooth down the edges around the curves. I genuinely have a completely bubble-free screen protector experience - and apart from the U-shaped cutout around the front camera, you wouldn't know it's there. I didn't reset my fingerprint, found it did read it but had to think about it for a moment, so I have now reset my fingerprint just in case. Fingerprint sensor seems to work a dream now. Already (accidentally) tested the self-healing aspect as I have a bit of sharp fingernail - made a scratch, within 10 seconds it was gone. I haven't gone back in with a diamond drill bit, mainly because I'm not an idiot, but also because I don't need to do that. This isn't going to protect you from that, but it'll protect the phone screen from my keys or something. Literally got it today so can't comment on durability. Phone screen looks as clear as ever - wouldn't say it's particularly anti-glare or extra-glare-y but then again this protector doesn't make any claims that way. Feels silky and is genuinely non-smudgy with my finger grease. Buy it! I won't be for a little while because I've got the other two in the pack, but you should! ## Features - 【Compatible & Cost-effective】LK Samsung Galaxy S21 Ultra Screen Protector is specially designed for Samsung Galaxy S21 Ultra.The Package comes with Galaxy S21 Ultra Screen Protector and full accessories for installation. - Ultra-Thin & Lightweight: Only 1mm thin.

But sucks in many areas *by B***N on 29 January 2025* Im on my second of the three this came with which i bought in mid 2023. First film lasted about a year before it started peeling away and i had to replace it. The reason i got this is that the glass protectors for the s23U all cause issues with the curved screen and fingerprint sensor. I gave up on those and went with a plastic film. This is the only one i tried that felt smooth enough to not drive me nuts and also applies very easily without trapping dirt underneath which i cannot stand. Unfortunately this suffers the issues of all plastic films. My fingernails occasionally scratch the film leaving a small line that doesnt go away without replacing the film and also, i get smudges all over from the skin oil on my fingers which also drive me nuts. And im constantly having to wipe with a microfibre cloth. Also it causes a lot of issues with the Spen as if you press down a little too hard it will scratch a groove into the film and doesnt glide smoothly like on glass. I have no issues with bubbles unless it starts peeling and the thickness is thin and great. Overall decent for a film protector but sucks compared to the bare glass and glass protectors when they actually stay on and phones dont have under screen scanners. ## Frequently Bought Together - LK 3 Pack Screen Protector for Samsung Galaxy S21 Ultra, Self-Healing TPU Film, Anti-Scratch, No Bubble, Touch Sensitive, Support In-Display Fingerprint Scanner, Alignment Tool Included - OtterBox Commuter Series Case for Galaxy S21 Ultra 5G (ONLY - Does NOT FIT Non-Plus or Plus Sizes) - Black - Samsung Galaxy S21 Ultra 5G, US Version, 128GB, Phantom Black - Unlocked (Renewed) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/269529117-lk-3-pack-for-samsung-galaxy-s21-ultra-screen-protector](https://www.desertcart.pt/products/269529117-lk-3-pack-for-samsung-galaxy-s21-ultra-screen-protector) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-06*
