All You Need to Know about SCREEN PROTECTORS

PET, TPU, or Tempered Glass – all you need to know to choose a screen protector​
A bit of a disappointment in the past, today's screen protectors are easier to install, cheaper, and better than ever in every aspect. There are three varieties - PET film, TPU (polyreuthane), and our undisputed favorite - tempered glass. And then there are two methods to get them on your display – dry and wet. So here's more about how screen protectors work and what they offer.
PET Film
Obviously, PET doesn't stand for a dog or a cat. It means "polyethylene terephthalate" - a type of plastic that's available in many variations depending on specific applications. In the manufacturing industry, it's used for mundane stuff like liquid and food containers. But this doesn't mean that PET film protectors are glorified water bottle plastic. They consist of polyester film with a scratch resistant matte coating on one side and a silicone adhesive on the other. Quality ones are quite clear and add a functional anti-scratch layer to your screen, but have no impact protection. And their scratch-resistance isn't better than what Gorilla Glass already has - it's limited to fingernails, coins and keys. They are cheap, and usually come in packs of three or more. Their downside is that plastic is the easiest to discolor from sun rays and oil buildup from your fingers, and it doesn't feel as nice as glass does to the touch.
If you have a cheaper or older phone, or you're fine with the most basic and affordable screen protection, get a PET protector. The manufacturer doesn't really matter, but if you have a soft spot for a particular brand, there's no reason not to go with theirs. Chances are that protectors from established brands will be better cut-out for your device and won't leave loose edges that can catch on to your clothes and peel the protector away (it has happened before).
TPU
TPU (thermoplastic polyreuthane) is next in the screen protector food chain. This is chemically-enhanced plastic whose properties include scratch resistance, elasticity, oil and grease resistance, and increased toughness. Since the material is elastic, it has limited "self-healing" abilities. This means that its slight softness gives it the power to absorb non-extreme impact, such as most drops and lighter scratches, while retaining all or most of its original composition. For example, lighter scratches usually leave just a small dent in the soft plastic, which slowly returns to normal.
The "military-grade" tag most TPU protectors proudly carry is worthy of an explanation. One manufacturer says that this material is used "to protect jetfighters". And what do you know, it's true! Skim through this Aerospace Surface Protection brochure - it's full of polyreuthane protective tapes used for "aircraft and windmill leading edge protection". However, getting a TPU case or screen protector doesn't guarantee it's made of the same quality of material. But your smartphone also isn't a fighter jet, right?
If you are willing to pay a slightly higher price, a TPU protector is, logically, better choice than PET film. At the very least, it's going to provide better impact protection (although you shouldn't be pushing your chances). It's also nicer to the touch, although it isn't glass-smooth. Arguably, the best part is that you'll get to explain to your friends and acquaintances how your phone has "fighter jet protection". Pretty cool, huh?
Tempered glass
Protection with a temper! Tempered glass (TG) screen protectors are the absolute best you can buy. Material-wise, a high-quality TG protector is multi-layered, usually starting with shock absorbent silicon on the bottom layer, followed by PET film, and an optically clear adhesive to 'sandwich' the previous two layers with the next two, which are tempered glass and oleophobic coating. All of this scratch, oil, and shock protecting goodness is compressed into a <0.4mm-thick sheet that's no harder to apply than a PET or TPU protector, and none heavier or otherwise obnoxious.
A glass protector is superior to its alternatives in every way. It has better light transmittance, making for a clearer display. It's anti-reflective and glare reducing. It has oleophobic coating, which heavily reduces fingerprints. It has the smooth feel of actual glass under your fingertips. Unlike Gorilla Glass 3, it resists sand scratches, making it the only viable option for beachgoers. And let's talk about shock protection. T-glass protectors boast a material hardness rating of 8H to 9H, meaning they are hard enough to resist scratches from anything that's not topaz or corundum (extremely hard aluminum oxide). Yet, they aren't completely shatter-proof. Since this is toughened glass we're talking about, in the event of a fatal drop, the protector will absorb all the damage and break into tiny shards. Chances are pretty good that your display will end up unscathed underneath. Thus, instead of having to replace the entire screen, you'll only have to get a new protector. Which is easier on both your soul and your wallet.
As you probably expected, tempered glass protectors are the most expensive kind. Most renowned brands can charge up to $40 for their products. And although that's money well spent if you are rocking an expensive flagship smartphone, excellent tempered glass protectors can be found for less than $15 online.
Dry vs Wet Mount
There are two methods for installing a screen protector - dry and wet. The method is usually specified on the box.
The dry method keeps the protector glued to the screen with static electricity. There's no adhesive involved, and the application is very straightforward. In short, you're supposed to enter a dust-free environment (either outside, or in your humid bathroom, preferably naked to prevent dust specs from your clothes), clean your phone thoroughly, align the protector and apply it. After a few tries, you will end up with near-perfect results. You don't have only one shot at this. Most dry-application protectors will let you carefully lift them off the phone and take care of misalignment and dust particles before trying again. Some even come with an electrostatic paper band to help you get rid of annoying dust.
The wet application method works by spraying liquid on the underside of the screen protector. It's a convoluted and awkward ordeal. You're tasked with the very precise placement of a thin, wet sheet of plastic - quite frustrating, because the liquid adds weight and gets the protector folding and dancing in every direction but the right one. Allegedly, wet protectors are easier to place without forming air bubbles or trapping dust, and are more resistant to peeling. If you mess up the installation at first, they too give second chances at applying them correctly. But all the phone drying, protector re-moistening and getting rid of excess liquid between it and screen is quite the patience test.
Wrap-up
With so many options available, and at very fair prices, getting a screen protector for your device has become a no-brainer. PET film products are the best choice for basic screen protection. TPU protectors can be a bit rare, but they have the best ratio of affordability and toughness. Finally, Tempered Glass protectors offer the ultimate in protection and feel, but they are the priciest of the bunch. Still, even the most expensive ones make sense for flagship smartphones and tablets.

HAVING SCREEN PROTECTOR ? USEFUL OR NOT ?
How important a screen protector is for you?
Matte or clear type screen protectors - choose your poison!
If you are planning to get a screen protector, the first question that a seller will pop up to you is do you want a matte or clear type of screen protectors. There is absolutely no difference between them both in terms of quality but what makes them very distinctive is the looks or outcome after installation. Matte type is great for those who hate to wipe off the finger prints and those oily stains on your screen. For the record, if you are touching your screen, there is absolutely no way to avoid the smooches. If you are going for the matte type, you can well kiss good bye to those clear and high resolutions displays (Retina Display for iPhone and Super Amoled Plus for Samsung for example). However, the positive side of matter type is of course, anti finger print ability.
Gorilla Glass - is it worth taking the chances?
I know this is one of the most common questions for most. Can I actually count on Gorilla Glass to protect my smartphone from scratches. Gorilla Glass is made to protect the phone from normal damages but always keep in mind that Gorilla Glass will ensure the phone is scratch resistance and not scratch proof. Scratches could happen over time and again, it boils down to your self preference if you want to risk it. If you are a safe handler, then you could be fine with this option.
Touch sensitivity issue with screen protectors - myth vs real
Some users complained that when they fix screen protector on their phones, they felt there is sensitivity loss. Users around the world might experience this regardless the quality of the screen protector in this case. Although it is very rare for the occurrence, it could happen and trust me on this as I experienced it myself. If you are using a matte type screen protector, there is a higher chance of this compared to a clear type. Also, the chance of this increases if you uses a cheap screen protector.

What about nano liquid screen protector

It's also called hard shield and it's basically a spray that solidifies afterwards in about ten minutes. I personally have not used it . It's basically used for reduced smudges and finger prints with some protection but it has mixed customer opinion about it. The most common being uneven and taccy surface which might be due to uneven spray.

SMALL REVIEW FROM A USER
I have a tempered glass screen protector for my Note 3 and it fits and works perfectly. It's been on my phone for 2 months now. Not a single scratch to it and no peeling or dust accumulation at all. I would recommend one any time over a plastic protector. I got mine from a company called fasttech. They are very cheap compared to UK sellers and the company is very reliable even considering that they are Chinese.
AN OPINION FROM A USER
Tempered glass has an adhesive throughout the whole surface, not only the bezel/perimeter area.
The difference is very simple. If you want scratch protection, get a film screen protector, but make sure to get quality PET 3H hardness film like the one sold by iSmooth and Spigen. Cheap ebay stuff is thin, will scratch, will bubble after some time, and will have rainbow effect under the florescent light. If you want ultimate shatter protection - get tempered glass. On impact the glass will shatter without affecting your display. Spigen and Seidio makes some of the best ones. I'm personally a big fan of Seidio VITREO and been using it on my Note 2 for a very long time.

Nillkin 9H doesnt fit well..

I just did the whole proccess.
The whole thing doesn't cover the active screen fully. There is a thin uncovered part on the edges.
All around the protector I have a "lifted" frame that doesn't even touch the screen. Dirt and fiber will probably get stuck in there over time...
Also the camera glass protector is made out of a pretty non-smooth glass.. I can't even clean it with a cloth without leaving residue behind.
IS IT JUST ME?
Why is it so low quality??

I have one and the actual screen part is fully covered. Also, My protector is ever so slight;y lifted but not much. My camera protector is good as well.
I bought mine on ebay for under $10. Maybe they have quality control issues?

I have bought also Nillkin 9H protector and it fits as it should because it is made so it covers only the flat part of the screen.
Edges of the screen are rounded as you have noticed and protector can not fit on top of them , I know this because I had protector that was covering whole screen and it was not good believe me.
Full coverage screen protectors are not good for two reasons:
1. beneath the protector where are the edges dust collects and because there is very small gap you can not clean it. (looks horrible)
2. because protector is not in contact with rounded edges of the screen it will crack in 99% when it falls. (This is based on my personal experience)
So do not worry you'll get used to it and appreciate the benefits.

Can somebody please take a picture of how much gap there is to the edge of the screen for Nillkin? I have a noname screen 9H protector and considering switching to Nillkin if it has less edge gap.

Really good screen protector

Hi People !
I bought a great screen protector for my Samsung Galaxy S6 Edge. The link is here:
http://www.cellbeeusa.com/shop/sams...d-glass-0-3mm-thickness-2-5d-curved-edge.html
It's a tempered glass for the Edge and it is awesome.. Cellbee's tempered glass fits from edge to edge - which completely covers the phone. After a few days of testing it... the screen protector doesn't detach itself or comes off from the edges as most claim that their screen protectors after a few days come off around the edges. Now, I didn't drop test it and probably will not unless it happens accidentally, but from the material it really feels solid. Most people that also have this ( my friends ) claim that they are satisfied. If you are looking for a great tempered glass solution then go with CellBee... you will definitely be happy. Note: ITS NOT A GLASS, but very shock absorbent material
Here is the youtube video for installation: https://www.youtube.com/watch?v=kazGyM3SLEA
Just my 2 cents

So they advertise it as glass but it isn't actually glass...
Confusing stuff!

It's not glass... it has a 9H+ hardness as glass but its made out of absorbent materials which protect your screen. Now, as I said, I am not willing to drop my phone to test it out.. but it is a soft material, but much thicker than PET films and really feels good in the hand. I am just stating my opinion on what I feel, and how it looks. If I do drop my phone accidentally than yea, I will report back here. I am waiting for a tempered glass solution but my friend google told me that it will be a long time before they come up with a tempered glass for the edge. The Note 4 Edge still doesn't have a tempered glass. So... better this than nothing. Of course there are other brands like Spigen, Verdus, etc.. but read bad reviews about it... the other good reviews are from Skinomi... which people like.. but I'll stick with this.

That was one of the crappies screen protectors I ever used. Stop using the term tempered glass to describe it.

There's already a thread with this. Apparent it's bad, chips/scratches easily even with your fingernail, not to mention it's not tempered glass.
False advertising and a bad screen protector.

Why is it crappy in your opinion ? Tempered glass - no... its not tempered glass.. but it has the hardness of a tempered glass 9H+. For me, I am using it mostly have my keys that are in my pocket with my Sammie and no scratches at all.

Please do not make claims like this when you have no method to verify. It has been tested and failed miserably.

Interesting. Paid advertising? First it is tempered glass, but suddenly it isn't.

I've had this screen protector for since they started shipping in April. Currently looking to replace it. It is getting what I would call a little foggy and gets marks in it. The film seems soft under pressure. You can put a mark in it with your finger nail if you wanted.
At least on mine.
I'm not a fan.

I very well could be incorrect, but from what I understand, the tempered glass screen protectors are not able to produce a good product for this phone-- because each s6 edge is SLIGHTLY unique. With some of the plastic ones, there's some maneuverability, but not with glass.

Soft material? Is it also TPU? After trying some TPU's protectors, no good, too ruggy... no good on finger touching
Just found one with hard PET, anyone tried this item? Pls advise!

Samsung S9+ Official Screen Protector on Note 8

Have anyone try this one yet? I can't really find a really good screen protector for my Note 8. I found this...
https://www.youtube.com/watch?v=xnYkT5Egguw&frags=pl%2Cwn
Its PET (Plastic) and its like tempered glass but with full touch response.

This is a foil so nothing WOW... There are better products especially GLASS with full adhesive

No. You can't compare the two. The PET is nice for being more flexible so it doesn't "shatter" like tempered glass.
I prefer getting tempered glass to absorb actual impact from sharp objects then dissipate it otherwise.

no, last time i used this screen protector, my s8+ glass crack , 1 meter falling on floor

Anyone tried the pure gear hd tempered curved full adhesive glass?

Can i still use samsungs clear case if i install a tempered glass screen protector?

Most tempered glass screen protectors come with an install frame. Can i still use the clear case or will the frame get in the way?
I have a lg v20 atm and if i use a tempered glass screen protector i will sometimes get oil like stains on it. Does the same problem exist with the note 9? I will most likely get a normal 13€ screen protector from amazon.de and just hope that the s pen will still work, that i can still use a case with it and that there wont be any annoying oil like stains

Personally I haven't had any compatibility issues between cases and cheaper screen protectors, since most of them don't cover the screen edge-to-edge. What will likely happen with the cheaper ones is the rainbow effect resembling an oil stain which you mentioned - this happens because underneath most screen protectors is a microscopic dot matrix keeping the glass slightly elevated from the display surface, with glue only on the edges of the protector. To avoid this, what you want is a screen protector that utilizes a full glue structure; in short, a glass protector whose entire surface area is adhered to the display. These are sold less and less, because generally they're very tricky to install on curved glass. You might want to consider products like the Whitestone Dome, which uses liquid UV glue.
You don't need to worry about the S pen - Unless your new screen protector is made of metal, it will work with every film or glass sheet out there.

I've got a Whitestone Dome protector fitted to my NOTE9 and I'm using the Samsung clear case that came with my phone.
No issues at all, the Samsung clear case and Whitestone Dome protector do not interfere with each other.

Just confirming... are you referring to the Samsung Note9 S-View Cover?
If so, most screen protectors shouldn't interfere with the case. The frame you referenced is generally for installing the protector, then it's removed.
I use an S-View Cover. I like it in general, but two things:
1) Anticipate that the cover won't set flat for a while (if ever): Some have used a hairdryer or heatgun along the rib to get it to relax. That helped mine a bit.
2) It scratches easily! If I had a do-over, I'd try to find a protective film to cover it

I've got a Whitestone glass screen protector and the Samsung case has no problems, also have an Otterbox Symmetry case and no problem with that one either. Like was said most glass screen protectors don't go right to the edge so most case should have no trouble.
