ASF actually prevents from back glass shattering?? - Sony Xperia Z Ultra

Hi guys,
There is anti shatter film on the back as well as on the front right? What I'm concerned about is the back. White z ultra hides fingerprints and scratches, so I don't really have to put a protector to hide those, but I'm wondering if I don't put a tempered glass protector or something on the back, the back might crack some day.
How preventative is the ASF? Is t actually anti shatter?? Even if I drop it, the back glass won't shatter or crack?
Thanks.

removing and replacing screen shatter-resistant protector

The Xperia S comes with a pre-applied shatter resistant screen protector.
Now the thing is I got a scratch on mine. Which kinda sucks. How easy is it to remove it and then replace it with a new exact same one?
I bought a pair of screen protectors. But they don't fit all around the screen like the shatter-resistant protector.
They cut out around the sensors, camera and speaker.
So. Any tips and tricks?

That's because you're supposed to cover the anti-shatter sheet (which is not a screen protector just anti-shatter) with a screen protector that you can easily replace.
I just posted a thread in this same forum section about official Sony ones I got from Japan. But remember they are not the same as your anti-shatter sheet, you're supposed to put them on top of the anti-shatter sheet.
In terms of what they cover, they are the closest to the anti-shatter sheet as they cover all the sensors, the Sony ones just don't cover the camera and the earpiece.
If you order the Sony potector, you have two choices. You can either put it on top of the anti-shatter sheetand hope you wont be able to see the scratch anymore through this one or you can remove the anti-shatter sheet and place this one down alone. Its up to you.
I've already removed the sheet. It's now completely free of protection as I screwed up putting on the screen protector.
It's more sensitive dust and fingermarks now, but overall I'm happy. Will be placing a screen protector on it soon again when I get around to it.
Took mine off today. I seriously, repeat, seriously doubt that sheet can do ANYTHING. It peels off like regular screen protector, does not glue to the glass at all. Once you have a corner up it lasts less than a second to peel it off.
For some of you repeating what SONY want you to believe, carry on.

That's what I say. The screen is much better without it.
Should i remove the screen protector
I have Scractched My Sony Xperia S , and it kinds of irritates when there is more White ,, I heard and read that the factory applied screen Protector can be removed, the Question is , is it a screen Protector or a shatter Protector..
In the case i do remove it how do i clean the glass if there is any residue gum and will it affect the screen in any way... Should i Put on a New screen Protector Once i Remove the original Factory fitted one.

does Xperia U have the same screen shatter protector? mine is scratched in the second day, now I applied a screen protector over it

Yes it is a shatter protector thick layer, I damaged mine too (Xperia P), I removed it and then applied a good quality screen protector, no residue no marks are left when the shatter protection is removed, hope this helps.

I had no idea the provided protectors had to go on top of the already applied one. Is it written in the manual/instructions?
Anyway, what is a good screen protector that can replace the shatter one to a good enough standard? I have scratches on mine, a rather large scuff over the front camera, making it unusable. So I suppose I could remove it and replace it with a protector?
Any recommendations?
It doesn't prevent shatter, i know that for a fact!

Thats probably why it's not called a shatter preventor protector

How easily can the screen without the preapplied protector be scratched? Just from carrying in a jeans pocket?
Should I apply a screenprotector if I remove the original one?

The screen of the Xperia S is pretty scratch proof. Like really proof. The shatter-resistant protector on the other hand gets scratched in no time.

Yeah if I put my face up to the screen during direct sunlight I can just make out tiny scratches. Some of them are not permanent and some clearly are. The screen has been very good vs heavy scratches, but still gets light scratches like every other phone screen I have had. If you were to put a screen protector on you wouldnt even notice the scratches. Light scratches will always happen and it doesnt really bother me unless I can see them.
Edit: I did receive a free Spigen screen protector so I will try it out and see if I like it or not just for the hell of it. Generally though I prefer the naked screen and even my old hero with gorilla glass 1 came through just fine except for the minute almost imperceptible scraches.
Folks, Gorilla Glass is a marketing ploy. It doesn't offer any real scratch resistance over normal glass, but the compound it's made of makes it less likely to shatter (two different things). When it comes to scratch resistance, you're looking at the Mohs scale.
Mohs scale of mineral hardness - Wikipedia, the free encyclopedia
You may be more familiar with this than you think. Diamond is a 10, the hardest substance known to man. Diamond can only be scratched by another diamond or a laser.
Glass has a rating of 6-7, depending on the hardness of the glass. Plastic is a 3-4.
If you take your keys over a glass screen (or a glass window), touch it to the surface, and rub with a little pressure (just enough to gain a degree of resistance), you WILL NOT scratch the glass. I've even scared the crap out of someone by hacking at my Zune HD's screen with a carbon-steel steak knife, and not a scratch.
So what will cause you to scratch your glass screen? Two things;
-a softer material (like metal) and force, not resistance. Yes, if you slam something into the screen, it may very well get a small crack, small enough that we see it as a scratch. Because, while glass is very scratch resistant, it easily shatters. It's force that gives us those small "scratches."
-dirt/sand - Sand (quartz sand, specifically) is an active ingredient in glass. If you get small particles of sand or other types of dirt on the screen and then wipe it off with your shirt (or even a microfiber cloth), you can develop small scratches in your screen. The most annoying is those who wipe with a circular motion, as it leaves rings in the screen. Want to avoid this? Take a SMALL amount of Endust for Electronics and a paper towel and gently wipe off the screen. The liquid will act as a buffer between the screen and the dirt. Then, take a microfiber cloth (those little eyeglass cleaning cloths that come with screen protectors) and wipe off the residue left by the Endust and any pieces of the paper towel.
When you use a quality screen protector (SGP, Clarivu, Martin Fields), you're putting a plastic overlay over the phone. While this will scratch more easily than the glass screen, if applied correctly, it acts as a shock absorber, thus making it harder for the screen to shatter. It protects from scratches by taking the scratches itself, and it protects from shattering by absorbing the force of the blow.
The wet applications like the Invisible Shield are so thin that they don't noticeably increase shatter resistance. They'll just keep the screen together when shattered. The Invisible Shield is harder to scratch though, making it so that you don't have to replace it as often (it looks nicer longer than a normal plastic screen protector). Basically, it protects from scratches by deflecting them, but doesn't offer any real shock absorption.
Gorilla glass claims a hardness of 9 on Mohs scale which is utter bs. It realistically has a hardness of about 7-7.5 max. Normal glass can range from 6-7.2 depending on the type. Diamond is 10 and Sapphire is 9 which is what the make high end watch faces out of but is damn expensive. If Gorilla Glass was a 9 then they would use it for the watch faces since it is much much cheaper. I have a Citizen watch that has sapphire and the face is scratched as **** because I have had it for 12 years.
Remember as long as the scratches are the insanely small type caused by sand grains and such, you can easily get some special polish and buff those right out. The one nice thing about our screens not having oleophobic coating is you dont have to worry about damaging the coating when you polish it.
The best way for a manufacturer to reduce scratches is to put a chin on the phone like the Hero had. This way the phone screen never touches the ground.
When I got the phone I thought that the phone had one screen protector installed and that the other one in the packge was spare. How wrong I was. Now the shatter-resistant protector is full of small scrathes, even tough I haven't had keys or anything else on the same pocket. I've had the phone for about three months now.
I ordered Martin Shields few days ago, and I'm going to replave the shatter-resistant protector with that.
I had Wrapsol on my Galaxy Note and was pretty satisfied with it, but unfortunately they don't make one for P. My wife has Zagg on her Galaxy S, but it's bit too stick for my taste.
I put a screen protector on today to test it with one and it was on for all of 30 seconds before I tore it off. I just cant stand the things. Perfect thing for me would be a fold over case but as I use my left hand for the phone, they all fold the wrong way.
The phone was completely unusable for me after removing the shatter protection. The glass itself is a sticky mess, even after wiping of the goo left from the shatter protection, fingerprints and dust stick like crazy and is a real chore to clean.
I bought a Steinhall crystal clear film and the phone is now smooooooth as butter. I absolutely love it.

It gets better after a while. Mine is nice and smooth. I got a free spigen clear with my case but it didn't feel as good as bare glass.

Gorilla glass only for front glass ?

My OnePlus X seems to have micro scratches on the back but not on the front glass...
So do you know if there is also a gorilla protection on the back glass ? Or only on the front glass ?
I don't see why they would want to put gorilla glass on the back. So no, gorilla glass is only on the front.
I was thinking that the back glass and the front glass were the same, because they have the same dimension and the same form factor (I don't know if my english is perfect... I'm french )
But if we can have confirmation... I'm worry because I don't want scratches on the front glass...
You should protect both.
Have a look to the pics here :
http://forum.xda-developers.com/oneplus-x/accessories/oneplus-x-screen-broke-easily-t3250916
Even with protections... If the phone suffered a big fall...
But with a normal use, Gorilla glass 3 seem to be resistant to scratches no ? (not from keys or some stuff in pockets)
If you have some information about that and about the fact that only the front is protected by Gorilla glass 3, feel free to answer
From what I've found on the web Gorilla Glass 3 hardness in Mohs scale is 6.8, so it's just below quartz hardness which is 7. It means that sand grains which are mostly quartz will scratch your screen, so I'd suggest you to buy tempered glass screen protector.
Most good tempered glass screen protectors hardness is 8 (Nillkin glass is 9) and the higher the better. From my experience 9H glass is really hard to scratch. I tried scratching it with carpenters knife which is razor sharp and couldn't leave any marks on it. I even rubbed on it with sand paper and actually it's easier to break it or chip it off than leave some scratches.
As far as it goes for back cover I really doubt it's anything more than just a smoked hardened glass that is going to have much lower scratch resistance than the front, which means that most of hard items that you'll put in your pocket will probably scratch it and to prevent that you need to protect it with a case or some kind of skin (if there are going to be any).
For now if you don't want to put your phone in a case but want to protect both front and back from scratches then you may buy Nillkin set which comes with 9H glass for screen and plastic good quality transparent sticker for back cover (even includes a protective sticker for your camera lens if I got it right).
You have to remember though that glass protector doesn't protect whole front, since it doesn't cover curved parts of the front panel.
Perfect answer, thank you for the advices !

Fingerprint-proof Back Tempered Glass

Anybody here knows a quality tempered glass for the back of the Z5P that has a special coating to avoid fingerprints? I have the Chrome version and I don't like to put on a case but don't want to have scratches as well that's why I'm looking for a good back tempered glass
Sent from my E6853 using XDA-Developers mobile app
Impossible, the mirror effect makes even more the fingerpoints.., i tested lot of glass tempered for black and nothing.. its all the same
So the question is, why isn't anyone making a frosted glass back? Yeah we lose the shiny back which is kind of the fingerprint hell itself.
you can try finding them on ebay,some chinese sellers have frosted screen protectors (not glass) for front and back.
personally i have been using frosted ones since my hd2 days,saves the headache of having to wipe smudges and fingerprints.
it may not look nice but its a hell lot nicer than have fingerprints all over the damn screens.
Doesn't have to be tempered glass if you don't want fingerprints. Try finding a matt foil, it should be easier.

Protecting the screen from cracking

It's quite expensive to repair a cracked screen, so I'd like to protect my phone against it.
I'm thinking about doing two things atm: buying a tempered glass screen protector and a heavy-duty case.
Are there any other measures that come to your mind?

Huawei P10 - Tempered Glass Protection

Hi guys,
I just bought to me Huawei P10. I would like to ask, does the the phone come already with a screen protection? If yes what kind of glass is that?
After removing the plastic protection i noticed that there is a small glass or protection (very thin but is there) on the top of the screen. After applying a tempered glass on the top of it, because it is slightly bigger than that protection, there is a bubble of air all around the borders of the tempered glass.
So can anyone tell me what kind of glass is that that comes with the phone? It is easy to take it off? Should i substitute it by a tempered glass?
Thank you very much for your help.
Best Regards
It has Corning Gorilla 5 but no oleophobic coating under the factory preinstalled film, which is easily scratched. I have already removed mine and using this glass https://forum.xda-developers.com/showpost.php?p=75089574&postcount=32 it is not a full screen but it is not too big and aplies well with no gaps.
Are people really removing that "Corning Gorilla 5" glass and replacing for a different one? Is not good enough? or is one of those debatable things?
Apparently now i have two tempered classes on the top of my screen.
I bought this one:
https://www.amazon.co.uk/gp/product/B0759FWFTK/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1
Should i use the "Corning Gorilla 5" that come with the phone, or the one I bought is better?
Or should i buy a better one like the one suggested by ylapas: https://forum.xda-developers.com/showpost.php?p=75089574&postcount=32
Thank you again.
I dont see how you can remove the Corning Gorilla 5 screen and use a glass screen protector on it. you have to have the screen on to put on the protector.
