LK3 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

I have installed this protector on 2 phones. For the 2nd install (on a phone with an almost perfect screen) it looks like a professional did it. It was beyond easy to install and there are zero bubbles, not even around the edges. It's almost invisible, you have to look for the edges of it to know that a protector is on. The fingerprint sensor works beautifully, and the protector itself is as shiny as glass.Every detail has been considered to ensure that your installation of this protector is flawless and hassle-free. There's a little plastic piece that goes in the charging port that helps you line up the protector perfectly. There's tacky adhesive that holds the protector in place while you peel off the backing. There are the usual wet cleaning pad, optical cloth, and "dust absorbers" as well as a soft edge smoothing tool.Tips: Be sure to watch the install video found in the product photos above. On my second try, I paused and completed each step along with the video, and I got a better result than when I watched the video and tried to do it based from memory. When you're ready to remove the second piece of backing, be sure to start pressing with the smoothing tool where it is indicated. I did not start pressing far enough back on the first phone I installed this on, and it DID leave a teeny faint set of lines across the width of the screen.Does it hide imperfections on the screen? The 1st install was on a phone with light surface scratches that you could see and feel. The protector did not bond to the scratches, and there was a slightly visible bubble in those spots. On the 2nd install, the screen only had light scuffs that you could see if the phone was tilted just right, but you could not feel. The protector hid those perfectly.Potential negatives: I removed the first protector I installed (had to return the phone) and discovered it's kind of a stretchy, soft (in a rubbery way) material. Because of this, I could imagine that it might get "dented" if pressed on by a sharp or hard object. But there are 3 in the package, so it could be replaced if that happens. Also, because the material is kind of rubbery, my finger doesn't glide quite as easily as it did on glass for swipe typing. I consider these both minor inconveniences for some comfort that my screen is protected from getting scratched up in my bag. I paid 11.99 for a 3 pack.

The description of this protector is accurate. If you have a clean flat table top and you carefully follow the video instructions, it is very easy to quickly install this flexible plastic film with no bubbles. It will adhere well enough to stay in place as long as the phone is inside a book style case. If you just use the phone with the screen exposed, and place it in your pocket, tiny amounts of dust and lint will eventually lift the corners and edges. Due to the way Samsung screens are curved, some protective cases will contact the edge of this film and may cause it to lift away slightly. The film is soft and flexible, so the fingerprint reader should work.The film is incredibly smooth, almost like glass. Sliding a finger or stylus is very easy on the surface. It is soft, so a fingernail or stylus or any object will leave an impression on the film temporarily. The soft material allows imprints from objects or phone case cover to develop lines and dents which will heal after a few hours. The surface returns to a very smooth and shiny flat appearance that looks almost like a black mirror finish when the phone is off.The adhesive layer will fill and hide fine scratches in a phone screen. It is possible to install this flexible protector on a slighty damaged screen and completely hide tiny defects in the glass screen.The box has plastic screen protectors and three glass camera covers. The camera covers have black coating to prevent the flash from causing light leakage through the cover into the camera lenses.The plastic can be damaged if you press too hard or touch it with a sharp object. It is not hard like a glass protector. This plastic film cannot crack like glass. It may not absorb energy from a strong impact. The force and shock may be transferred to the phone screen more easily than if you had a hard glass sheet protector.On the other hand, the soft plastic may be better able to cushion some types of impacts better than glass. Without reading a properly designed experiment, there is no way to speculate on how this protector will resist damage to the phone screen in comparison to a thin glass protector.The use of a medium adhesive strength allows for easy , clean removal when you want to replace the protector with another one from the package. Some protectors have hard adhesive, which can be difficult to remove.I consider this product to be well designed, easy to use, effective, and a good value for the price.December,2021 UPDATEAfter using this protector for almost a year, in many indoor, outdoor, and sports environments, I am astounded at the durability and self healing properties of the soft plastic film. I have accidentally transported my phone with other objects like house keys and metal parts that made wrinkles and damaged the soft film. The film protected the glass screen, and looked like it was destroyed on a few occasions. To my complete surprise, I was able to smooth out the film and over time all of the air bubbles escaped and the film returned to the original flat ultra smooth surface. Even on tiny area that was cut completely through the film healed so well that the 2mm long cut is almost invisible. I was absolutely certain that I would need to remove and replace the damaged film each time, but the overnight recovery returned the condition to nearly like new. Initially, you may notice that contact with any object will leave an imprint on the surface of the film. In almost all situations, this imprint will return to perfectly flat and smooth overnight. The surface feels just as smooth as glass, but there are very tiny visible imprints in the surface after 11 months of use.The package contained two soft screen protectors. Each one should last at least a year. A good value and easy to install and remove, without leaving adhesive contamination on the phone. I don't expect that I will ever go back to glass screen protectors, they crack too easily and some use very strong adhesive. Glass protectors don't have the ability to allow air bubbles to escape, which makes this file nearly a miracle of materials science. Excellent product.

Es compatible con spen y el desbloqueo de huella dactilar, además no se nota que este puesta, seguí las instrucciones para la postura y todo salio bien

Leider war mein vorheriger, sehr starrer Displayschutz kaputt gegangen.Das war eine Panzerglasfolie aus dem Laden (Kostenpunkt 15 €).Unten war der Fingersensor im Panzerglas separat zu sehen. Hier war eine Art Aussparung.Nachteil: Oft bedurfte es mehrer Anläufe bis ich mit meinem Fingerabdruck den Bildschirm entsperren konnte.Von dieser Schutzfolie bin ich von Beginn an begeistert. Profianleitung zum Aufbringen der Folie. Meines Erachtens mindestens so gut wie im Laden vom Profi installiert.Saß sofort blasenfrei perfekt. Der Fingersensor funktioniert nun wieder exzellent. Immer beim ersten Berühren des Bildschirms. Ich kann zwar noch nichts über die Schutzwirkung der Folie sagen, da ich sie gerade erst angebracht habe, aber Handling und Optik überzeugen mich absolut.Kann ich weiterempfehlen. Daumen hoch!

This is by far the best screen protector set I have ever bought. Everything is in there, even a guide to make sure you align it perfectly. It fits EXACTLY. As 50 year old with OCD, I can tell you that thus is the firsf screen protector EVER that put a smile on my face. Thank you! :)

No soy muy mañosa poniendo protectores pero quedó genial. Sencillo y bueno. Vienen 3, una pequeña gamuza, 3 sobres con toallitas de alcohol, 3 pegatinas por ai hay alguna burbuja y un aparato para presionar cuando lo has puesto. El envio rápido. Muy contenta con la compra.

Con la sua facilità di installazione e la resistenza alle bolle d'aria, questa pellicola offre una protezione discreta e efficace. Tuttavia, è importante considerare che se volete più affidabilità è meglio un vetro temperato, se volete più durabilità invece va bene la pellicola in idrogel. Poichè il vetro temperato si protegge efficacemente il vostro schermo, ma una volta rotto va sostituito. Mentre la pellicola in idrogel, protegge dagli urti e dalle cadute, ma non come un vetro temperato, ma al contempo è più durevole.
