What type of adhesives are use on PET, TPU, and Glass screen protectors? - Samsung Galaxy S7 Edge Accessories

I'm wondering what type of adhesives are used to adhere screen protectors to the cell phone display. Maybe we can use some of strong, yet removable adhesives to help stick the screen protectors to the curved edges of the Galaxy S7 Edge. Then we can use whatever case we want and not worry about peeling edges.
Anyway, my question is about the types of adhesives used for this application.
Thanks!

There are a few used like silicone and double sided tape. Then you have wet and dry installed screen protectors which I'm not sure what adheres them. You don't want something too strong that would stick because they do get worn and need to be removed

So could I use some regular clear silicone, like from Home Depot, to stick down the edges of a screen protector on the curved sides of the S7 Edge? How optically clear would that be? Would it be easy to remove later?

I wouldn't but it's your phone. Don't know about regular silicone but what kind of screen protector are you trying to stick down that won't stay?! If your having trouble with screen protectors and cases, you can get a case friendly protector. Or if your looking for glass check out the thread about them. I'm running amazingthing and commuter case and it fits fine with no liftingood at all. I like cases but don't change them out often enough. I'd really just prefer a spring holster as that's what I used with my previous non samsung phones..

i have try the tpu protector, current techmology is very difficult to install on phone

The Edge screen with how most of the cases work today has caused me issues with almost every one I have tried. It always ends up getting peeled up at the top and the bottom and often the corners as well. I am considering trying to trim my skinomi screen protector to make it not get in the way of the case.

Why can't there be a tacky optically clear adhesive that we can use on the edges of screen protectors to make them stay down? The glass screen protectors have some sort of silicone adhesive on the edges, why not have that on PET or TPU protectors as well?

Recommended screen protectors, and also - tempered glass?

Hi everyone,
I'm planning on purchasing the Nexus 5X in a few days, just need to find the right accessories for it (cables, cases, screen protectors).
I was wondering if anyone can recommend a screen protector that has a cutout for the proximity sensor.
Also, I seriously only found out today there is such a thing as tempered glass. After researching a bit, I learned of it's pros (actually protects your screen if the phone falls) and it's cons (can crack easily for no reason ,poses somewhat of a health risk if breaks).
Pros: http://temperedglassscreenprotector.org/
Cons: http://www.clear-coat.com/blog/why-we-dont-sell-tempered-glass-screen-protectors/
Strangely, all the screen protectors I find on Amazon are tempered glass.
So, which one should I buy (tempered or plastic), and can you recommend a specific screen protector?
I wouldn't say they crack easily, but that'll depend on a bunch of variables. All I can say is it looks good and feels much nicer than the PET/non tempered glass screen protectors. Spigen is a good brand to go with.
Read the thread below:
http://forum.xda-developers.com/showthread.php?t=3214188
I recommend the skinomi screen protector, it's not glass. It's the kind that feels like rubber and applied via water. I love these.
How you apply it with water? They can get to te mic's, no? You have safe way to do that?
Hi, Im very pleased with Nexus 5X Screen Protector, Spigen® [Crystal] Full HD, I used to have it on my Nexus 5 and I was so satisfied that I bought it again for my N5x. Feels like glass, perfecly cutted you have 3x screen protector included, dust removal and positionning tool to hlelp perfect use. At least two times saved my screen on my old nexus 5. And almost nobody noticed that Im using a screen protector....
I've played around with a few screen protectors over the years, including some tempered glass ones. I can show you some reviews I've written, if you're interested.
Most of the cheap glass options are /not/ multicoated. What that means is, while they might be very difficult to scratch, they will cause some reflections, way more than the bare screen. Also, one of the coatings applied in modern multicoating is an oleophobic coating. That means a layer which helps the glass reject oils, including the skin oils on your fingertips. So applying a glass screen protector usually means you'll have to clean your screen way more often, and also that it will be considerably more difficult to actually clean the screen.
If you're dead-set on a screen protector, I highly recommend you find yourself a multicoated option. These will be no less than $20 even on sale. They can be $30+ normally.
Personally, I trust Corning Gorilla Glass 3 as sufficient in this generation. You might get a scratch or two over a few year span, but, virtually everything your phone will meet won't be hard enough to damage the glass.

You apply a thin layer them squeeze out the excess. It's incredibly easy to retry if you set it wrong the first time. You can push the water away from the mic and speaker and use a cloth to dab up any excess water.

There is something that I can put in the mic to seal it? I don't want to take risk(especially when you have holes in top and bottom)

I've been using glass screen protectors since May 2014. I swear by them. They don't crack easily like Clear Coat claims. I've only had to replace them twice. Once because an edge got pulled up months later so there was a air gap on one side. The second time, it actually did crack but that was after falls with a TPU case on. As many others have stated, with tempered glass screen protectors, that will crack before the actual glass of the screen does. And good ones don't shatter into little pieces like Clear Coat says. On the two replacements, I broke them fully and the pieces stay together. Also I really like the glass feel. Not sure how non-glass screen protectors feel though. Back when invisibleSHIELD was popular, that tacky feel wasn't nice.

Even though the image shows it is, some companies say that despite the image, their product does not cover the sensor.

Exactly. I think of it similar to a crumple zone in a car. It will absorb some of the force before the phone's glass does. Now of course, with a great amount of force like dropping it from 10 feet or throwing it, I'm sure both the screen protector and the phone's glass would break. Regular accidental drops should work out the way I described.
As for outdoor visibility, there's no noticeable decrease in brightness or increase in glare. All of the manufactures usually advertise something like 99.9% transparency.
Here's an interesting tempered glass screen protector review. Cued up exactly on the drop test to rocks and removal:
https://youtu.be/UnvC6EERMyI?t=2m21s
Keep in mind that plastic protects better than glass and plastic does not need to be replaced where as most drops will break a glass protector. It is made from a thin easily breakable material after all.
The reason to pay roughly 10x as much for glass is because it feels much nicer on your finger. Plastic can also cause rainbow like reflections and can be a bit harder to apply than one solid piece.
However glass costs a lot more upfront and in the long run to replace. A plastic protector is about $1 and if applied properly won't ever need to be replaced.

Yes plastic ones don't break break or need to be replaced but I don't think they provide the same impact protection in absorbing drops. You'll probably have a screen broken under the intact plastic screen protector.

I have no background on the subject but just thinking about it logically, I don't think glass can be as protective as plastic.
For instance RhinoShield only offers plastic screen protectors. Their test videos show how easily GG would break from certain impacts and how much plastic protects it. Even the best tempered glass can only hope to be as strong as GG.
My basic understanding of the situation is glass protectors work because it breaks and saves the screen underneath, where as plastic works by actually strengthening the glass itself.
However for each time the glass protector breaks and needs to be replaced, the plastic would keep on trucking.
I think the misunderstanding arises when a user drops their phone with a glass protector and it breaks thus "saving" their screen. But what if they had plastic? Would the screen of broken then? What if they had no protector? We can't say for sure what the results would have been. However to the user that is a clear indication of the glass protector working, where as I would say that's only a clear indication of the glass protector breaking easily.

Right. That's how I see it as a user. Also, the clarity, feel, and scratch resistance can't be matched by plastic.

I've actually dropped my 5x naked just once so far and got lucky without any cracks, but I do believe if I had a glass SP it would've broken. In the end I think it's luck and a good case that will protect from a bad drop as the screen protector is mainly for scratch protection. I've kept my glass SP as a backup in case the factory oleophobic coating stops working as effectively.

Silicone case that doesn't lift tempered glass screen protector

Hi All,
My preferred phone protection is to have a tempered glass screen protector and silicone case. Saved my old phone from bad damage a couple times while bouncing on the street.
Now... the challenge I have with the P9000 is that the silicone case that came with the phone doesn't go 'over' the edges of the tempered glass protector and pushes it off.
rather annoying!
Ordered some other silicone cases on Aliexpress but the same problem.
Anybody found a nice case that does the trick? Tried 'heat stretching' the case a bit for a better fit but no luck so far.
thanks!

yup same problem. i cut the case a bit and now it dont look nice . but it works.
Hi.
My problem was that one corner of the glass doesn't stick to the LCD. After I applied the silikoncase it fits.
I have the case that come with the phone.
I stretched it a little bit over the corners of the phones without heat.

Had the same issue what you need to do is force phone by slotting it into case then pull the lip over the screen protector. Do this to all corners and you'll have no issues.

Congrats on having it fixed without any drastic measures! I went the 'cutting route' for now since I had to replace the screen protector and didn't want to risk another one.
But I've got another set of silicone cases coming from aliexpress to check if they are a bit better!
I've got 2 P9000's (one for me one for my girlfriend) so actually I already wrecked 2 screen protectors.
Same problem here. Original case and aliexpress case. No luck.
i bought the official flip case and tempered glass.
tried the case first which fit but found the buttons a bit hard to press.
if you fold the case front behind the phone the camera is blocked also.
could view the on screen clock and notifications through the case screen window.
once applied the tempered glass the phone wouldn't recognize the flip case, so when i closed it over the screen remained on and the case window became useless.
this company do nothing right do they.
Had to struggle the same problem, but now i could fix it.
Just make sure the glass is positioned in centre on the screen. When putting on the case, make sure the case slips properly over the first 3 corners. For the last one, you can use any tool (i a used knife, but be careful ) to overlap the edge of the silicon case with the tempered glass.
No matter what I did, it wouldn't do it without lifting the glass

I have the same issue (sometimes) with matte film protectors and the standard case.
Always on the top right corner for me - where I've got fractionally less unprotected screen , so maybe very precise alignment of the screen protector would help you?
Pulling the case over the edge of the screen with my fingernails was enough for me
Cut the flip in the flip-case.

Cut the flip in the flip-case. Just kepping the hard back. This way you can use the glass and have back protection. I did this and works fine.

there is a space between the silicon case and the glass so they don't touch each other

The hard back in the flip case is useless. Too fragile, corners and button covers break easily, my P9000 fell just once not too hard and the screen left upper corner broke. Silicone cover is better protection
u can use scotch tape on the bottom corners of the glass to stop it from lifting, funny idea but works, if u want to save a new case cost.

Tempered glass + LOCA?

Getting tired of these crappy screen protectors. The glass ones only have some OCA tape on the corners which is problematic when water touches it. It also leaves air between glass and screen meaning touch sensitivity is impaired. I have one of these screen protectors and I have removed the tape. Is there a problem using LOCA to bond the screen protector to the screen? This is supposed to be a semi permanent installation. Right now the only problem I see is the adhesive pooling around the home button.
Isn't LOCA permanent though?
I would like to know what silicone glue the stock screen uses.

@Illogi.xbone You have any suggestions on good plastic screen protectors? I just want a buffer in case I drop the device glass first. With plastic, the screen would still shatter. Plastic screen protectors are also less of a fingerprint magnet. I always carry sharp objects and the plastic protectors keep getting cut up.

I tend to keep my phone in a separate pocket to anything else. I don't see loca working well but you can always give it a go. Plastic will always get cut and yes, the screen can/will shatter (same with tempered glass) but I prefer the coverage that they provide and resistance to fingerprint smudges. I have used Skinomi in the past, don't like their matte ones though.
Geez, if it has come to this point just use the screen as it was intended.

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.

Tempered Glass Screen Protector

What tempered glass is everyone using for the V60? I don't use the Dual Screen, so I just need it to cover the phone screen.
Dmax glass was the thinnest glass screen protector I have ever seen for any phone I've put glass on ever.
Came in a pack of two. I chipped and cracked the edge of one with my fingernail simply taking the film off to install it. The second cracked in a couple days later from setting the phone down too hard I guess.
LK glass had poor adhesion. Large air bubbles on the edges of the screen. Bad enough I took it off after a month to try a diffrent brand. Noticed the sticky part of the glass felt subpar after uninstall.
Now using Zagg glass and its okay. Doable for now. However a thin ring shaped air bubble is present on the Zagg around the edges of the screen. It's thin and even, and can't be seen when the screen is on. When off it looks like its gonna start peeling up at the edges.
The issue I had with glass is that its too thick to close the cover if you have one on the phone and one on the sexind screen
AmFilm is what I put on the phone today. Came in a pack of three. Probably the best protector I've tried yet.
Thicker glass, might be a true 0.3mm. No bubbles or rings near the edges. Sticks very well, good adhesive.
Touch is good and looks are good with the screen off or on.
However, AmFilm is slightly (1mm?) shorter and narrower than the Zagg glass.
The Zagg glass was 0.26-0.23mm thick and covered more screen surface. The Zagg covers more screen surface than LK, DMax, or AmFilm.
However, the Zagg never adhered to the screen edges completely resulting in a white ring air pocket along the outer edges of the protector.
The Zagg glass was stuck to the screen very well when I removed it. The outer air pocket never did grow in size, was very narrow, just annoyed me to look at when the screen was off.
Overall the Zagg was a good option, but maybe not for those like me that value good looks as highly as I do.
The DMax Armor glass I tried was so thin, it might be an option for the dual screen case. DMax could have been 0.15mm thick possibly. Really similar to the Baseus ultra thin glass.
It's very fragile stuff as noted above, but again DMax might be as thick as double overlapped film protectors.
For those looking at a good protector here is the link for what I am using. Installs with ease, no bubbles and halos.
