Hi guys!
For this test I used a set of keys and a cutter.

I hope you will like it
Cool. Was this a test device or your own?

Awesome, thanks so much!
I posted one a bit ago but that was with some knives....the box cutter is impressive.
I am more worried about the small pieces of sand, I think that is what scratches the glass more......But, this video has me almost convinced that I do not need a screen protector.
a test device
"Cool. Was this a test device or your own?"
Wow, this just proves that all the other people complaining about scratches just don't take care of their phones.
Super high, unrealistic drop test now? ;D

The screens smash pretty easily I think.....
I saw a video posted a week ago or so and waist high on the sidewalk smashed the screen.....
Confirmed my feelings about the screen. When i got the phone it just felt like it could withsand some abuse. Wouldnt go so far to try this myself.

Yes, the screen is more sensitive to strong falls than to scratches but as you can see it resisted the sharp cutter
It's advertised as scratch proof, not as shatter proof. Keep that in mind

It's not advertised as either. It's scratch resistant.

It certainly is scratch proof but as my device shows that actually the glass is very brittle! My screen cracked in my pocket! without me doing anything!

well a material can only be exceptionally flexible(ductile) or hard(strong), but never both. if you want a material to be more shatter resistant(ductile), then it'll be softer and less scratch resistant. Conversely a harder material will be more scratch resistant but more brittle and prone to shatter. its always a tradeoff between these two physical qualities.

Your problem occurred from a defect in the glass manufacturing process. I don't think that is a standard.

Although this is true in some cases it is not in all. Thanks to chemist and material scientist, treating or chemically finishing materials could give the best of both worlds. Go watch the gorilla glass test on YouTube, it is more scratch resistant than its competitors and almost twice as flexible.
Gorilla Glass has a lot to do with its surface finish as well as the glass itself.

Gorrilla or not, Its still glass!!!
Bottom line is anything harder than Gorilla glass which has a hardness between 8+9 will scratch the surface.
Iron, steel, nickel, lead, gold, silver or any medal are softer than gorilla glass, so they should not scratch the glass.
On the other hand, sand contains quartz and it could scratch gorilla glass, for example when sand is in your pockets (after a walk on the beach).
One more thing:
a common misconception is: 'make something sharp and it will scratch'. it's wrong. you can make your fingernail or your key as sharp as possible, it is still softer than the glass and it will not scratch.
So, no, keys wont scratch it (steel), but anything harder than 8 on the scale will with no problem. So anybody that has no scratches obviously hasnt made contact to the screen with anything harder than a 8 on this scale.

Not very relevant at all. ALthough what you say is true, it is not the hardness of Gorilla Glass that lets it perform the way it does, it's the way it is chemically treated that allows it to resist scratches.
You are just talking about a mechanical property but not taking in mind the material process. Yes those materials will eventually scratch the glass (common sense), but whatever the coating on the glass is has to wear off first.
Chemical treatments. There's definitely a lot more to it, I would have to read more extensive datasheets, but here are some.
http://www.corninggorillaglass.com/sites/all/files/GG2%20PI%20Sheet%20Rev%20b_050912.pdf
Corning® Gorilla® Glass 2 is an environmentally friendly alkalialuminosilicate thin sheet glass that is better able to survive the real world events that most commonly cause glass failure. Its superior
composition allows a deeper layer of chemical strengthening than is
possible with most other chemically strengthened glasses — making it
both durable and damage resistant.

Cool, thank you. That should help it withstand drops. I hate how fragile my sgs3 is.
The entire back of the phone is glass. Gorilla glass, yes, but still glass. It will certainly be more fragile than the GS3.
Sony never disclosed name of 2 companies it is using to make screen protective glass for Xperia Z and ZL.... but my query is will it be stronger than gorilla glass 3 which is touted as "drop resistant " glass
see GG3 power here http://www.youtube.com/watch?v=a2Mm9omndlU
I heard that Sony's tempered glass is supposed to be DragonTrail glass which is supposed to come from some company called Asahi or something (or was that a beer? I cannot recall:laugh.
Anyway from what reviewers said, Dragontrail is supposed to be 5 times stronger than Gorilla glass but I've looked all over the net and have never found any further videos from this company, nor came across anyone brave enough to do a drop test with this glass or even better, do a comparison video against GG2 or even 3 (if that's available).
'
There was a pretty cool demo of Gorilla Glass 3 at CES I think, which said they were comparing it 'some' competitor's glass which showed how much more powerful it was.... but after meeting so many friends with the Galaxy S3 with broken glass on the front that had cracked (sometimes as easily as a light drop at the wrong angle) I don't believe any of the GG2 adverts anymore and think they're all very carefully controlled.
Would also love to see more info on this glass and it's actual strengths!
The gorilla glass 2 on the SGS3 is abysmally poor and it has completely put me off gorilla glass, I do believe there is a drop text video on YouTube for the Xperia Z and it looks amazing

It is either shatter proof or scratch resistant.... cant have both at same time... thanx to the screen guard that sony puts on.... this video shows it... :

Sony is not using dragontrail of GG according to Sony https://twitter.com/SonyMobileNews/status/289572752229285889
I have read somewhere on a German side( through google translate and with the little German languages knowledge I posses) that they tested it and that both the protector as well as the underlying glass wasn't as strong as dragontrail, though pretty close.
I agree...
Hmmm so much for gorilla glass? Hahaha! Gorilla grass turned into monkey barbecue with the last test lol!!!
And here's for Iphone 5 drop test
And to test if it's useful for military war hahaha
When i heard a Sony representative saying that they are using 2 different companies for screen protection , I assumed that one company makes glass and other company makes that preapplied screen protector. No company name said anywhere about Z and ZL

Hmmm there are 2 reasons I could think of why they disclose this info...
1. It's a lie! There is no company and sony themselves is just the one making the glass.
2. They find the glass maker company great and decided to keep it a secret to avoid letting other manufacturers use the same glass.

Apple doesn't disclose who is making the glass for the iphone. and I think to do that as to make it easier to switch supplier or use multiple suppliers, so that is the third option
a forth option is that they really just use tampered glass and not a alkali-aluminosilicate type of glass used by dragontrail, gorilla glass and scott's Xensation.
if they do use a alkali-aluminosilicate glass or similar I think it could be Xensation glass as this is the only one not ruled out by Sony (that I know of)
Sony said they won't comment on supplier - it doesn't translate into "it's not Dragontrail". Maybe it is, maybe it's not. Most companies hide that - look at Samsung products - in some cases people believe that SX/Note X are using GG, but it hasn't been confirmed anywhere.
I honestly believe they used the best possible option - you don't build a full-glass phone, advertise it as super-durable, and build it from some cheap non-resistant glass.
Also, i really find comparisons to Gorilla Glass pointless and in my opinion GG is not that great to say the least. Had S2, Note 1 and Note 2 - all using GG1/2 and all of them got scratched pretty easily - friend's S3 shattered after waist-high drop, so we're not really amazed by it. I know, GG is good to have - but not having it is really not a problem, if you drop it on pavement - it will break. If it doesn't it's most likely because of good border/chassis shock absorbing properties, and not glass toughness itself. Look at Lumia 820 - people were moaning because it doesn't use GG, and it turned out that Nokia's solution is equally good.
So, Dragontrail would be great - if it's not, i still believe it will be quite durable. Tempered glass is used in automotive ( windshields ) and it survives A LOT of damage thanks to its shatterproof film and tempering. I think it might turn out pretty good - and if it turns out it breaks as easily as every other phone, then Sony will have a real reputation loss due to its advertising.

Dude, where did you come up with Dragontail being 5 times stronger than gorilla glass? What a load of rubish. It is aparently 6 times stronger than conventional glass, and I am certain Gorilla glass is not therefore 1 times stronger than conventional glass. The Vickers hardness rating puts Dragontail behind Gorilla glass, so in theory Gorilla glass should be more scratch resistant.
Gorilla glass 3 shows hardness and ductility in action. The harder the material the more brittle it becomes under certain stressors. The more ductile the material is the more impact resistance it will have and also be less brittle. So combine the two and you have what is demonstrated buy the Gorilla glass 3 vid.
Sony aparently have already used dragontail glass in a Xperia phone, so quite likely to be the case here. I am certain that most companies are being quiet about this due to contracts standing with Corning.
Not sure why people keep referring to shattered and scratched phone screens, these technologies reduce the risk not remove it, nor do any of them claim it.

Exactly, that's a mistake. DT is said to be 6 times strongen than conventional glass, not gorilla glass. Also, gorilla is probably more scratch resistant, but DT conpensates for it with extreme durability and resistance to shattering.

...only time will tell, I went screen protector free for a month and I dint get any scratch but i was being careful. Xperia Active use dragontrail, go youtube drop test on those...seeems to be super strong.
Well Sony went somewhat retard on this phone, they put the most fragile cover on a tough glass. ( Look up Anti shatter film )
And you need the cover for Warranty and the sexy Sony Logo. So I'd recommend some sort of cover. (Unless you're fine without the warranty)
There's plenty of covers and they don't ruin touch sensitivity or brightness at all. I'm using Copter atm, it's all good.
Sony went wrong by applying an anti shatter film. It's ok but don't print the Sony logo on it for G's sake. I and guess quite a few others like the Sony branding. The shatter film itself scratches easily. Didn't remove it so personally can't say anything about it when it's off but one thing for certain and that is that the shatter film is not scratch resistant at all! So in case you want to buy one and want the Sony logo, I recommend using a screen protector over the ASF.

Disappointing to be honest. My phone fell face down from a distance of about 30cm when I was getting out the car and now I have a chip on the screen (and I had a screen protector on it)
I've now had to buy a case for it as the back of the phone is scratched to hell with everyday use.
My Lumia 920 was indestructible and had plenty of drops from great heights.
I'm annoyed as I bought my Z direct from Sony for £530 at launch and now it's worthless if I want to resell it.

The NFC sticker is pasted on top of the anti-shatter film. (Yes, there's a pre-applied shatter-proof screen protector in addition to the screen protectors that are already included within the box.)
Dragontail may be best than Gorilla Glass 2. I have the original protector but YouTube is your best friend.
My Z fell from a table to the floor and one of its corners got chipped, not the glass but urghhhhh... Also, Im not sure if the sides are glass but they got scratched so easily too -.-
The glass isn't very scratch proof. I took the shatter proof sheets off, and after a couple of weeks there were some very fine scratches on the glass. I'm very careful too, the phone has its own pocket with no keys, coins etc. The glass seems less scratch proof than that the front glass on the iPhone 4, and I put replacement screen protectors on pretty soon after removing the pre-applied ones.
I don't know how people scratch it so easily - I have a screen protector front and back and I only have 1 minuscule scratch on the front from my headphones. I've dropped many times too, on carpet, tile, wood and concrete from distances >50cm too. A little bit of care goes a very long way, it seems.

I'm talking about the sort of very fine scratches you can only really see in strong sunlight, and wouldn't notice under normal usage. My Xperia had about as many scratches of that kind after a few weeks without a screen protector as my iPhone did after two years. It doesn't really matter which of us is the more careful, because I was equally careful with both phones and the front glass of the iPhone was a lot more scratch resistant in my experience.

I agree with the above statement.
We're talking about the kind of scratches that other people would claim do not exist on their phone. Then when i take it look i can see them.
I got given an iphone 4 from work a couple of years ago. As i did not spend any money on it i wasn't anywhere near as careful with it as i have been with my Z.
I would quite often have my iphone in my pocket/bag along with other items. I dropped the phone on concrete paving quite a few times because i would pull the phone out of my pocket using the headphones wire. I didn't care.
As i bought my Z i have been very careful with it to the point of ocd. Nobody else has touched it. I keep it in its own pocket at all times. When i take it out i put it on top of a cloth ( work and home desk). It has never been dropped.
After two weeks the screen on my Z had as many of these micro scratches as the iphone had after two years.
Thankfully they are the kind of scratches that are not visible unless at a certain angle under intense light. But i am gutted as i really like the look and feel without the antishatter. I added a crystal clear spigen protector and it is now impossible to see them.
Luckily i am getting a new one from work, so i will give this one to my dad and this time i will remove the antishatter (i prefer the look without the logo) and install the spigen protector straight away.
Not very scientific and maybe luck plays it part, but i thought i would share my personal experience.
My Z has a load of very fine scratches (only visible in good light, at a fine angle) right at the point my right thumb unlocks the screen, all in the direction I swipe the screen.
So it does sound like the screen is not so strong as other phones with gorilla. Officially, it is not known what kind of scratch resistant this glass is (so no need to repeat Dragontail, Sony does not say anything about Dragontail. Or Gorilla). This will not stop me from buying this phone (or other Xperia) but it sounds like I do need to look for a good screen protector. There is no way I can put a screen protector on top of the already placed shatterproof film, I think this is simply ridiculous, having two screens on top of the glass. But I have never had a screen protector and I have been pretty careful with my phones and my motorola razr maxx (Gorilla 1) looks perfect after one year (no mini scratches either), so I guess I will have to get used to having one with a Sony phone. Thanks for all the opinions!
I dont want to start a war on naked vs protected - that can happen elsewhere. My question is really just how much can gorilla glass 4 handle? Again, any drop could break any phone but what about scratches? Is throwing the 6p naked in a bag that might have keys, coins, etc. going to scratch the screen?
If you're that worried about scratches pay the extra $10 for a decent glass protector. As always refer to the mohs scale, anything harder than glass will scratch it (even if it is Gorilla Glass).

I appreciate your advice but really would like to focus on real world situations and gorilla glass 4, not the "just cover it"

he basically was citing real world. sand will scratch the glass regardless of how hard it is. corning released some promotional videos on what GG4 is capable of, but i wouldn't use it as gospel. at the end of the day, you have a glass device.
i've left my m360 naked since day one and it has GG3 on it. it definitely has scratches from everyday use and has never been in a pocket with keys, etc. just from bumps from objects, etc.
i'm considering leaving the body of the phone naked, but i WILL have a screen protector of some sort.

Well, he did kind of answer your question. On the Mohs scale of hardness (which is a terrible system to use in this case), I think GG4 comes in at about a 5.5? Something along those lines. Basically, what this means is that anything harder than that will scratch the glass. Sand (silicon and quartz), hardened steel alloys, tungsten, titanium, corundum (sapphires/rubies) and diamonds are all good examples of what will scratch it.
Just for clarification
Anything equal to, or harder, than x on mohs scale will scratch x
And gg4 is supposed to be 7 on mohs scale
The best example of a 7 is quartz

I'm just curious where you found 7 as the hardness. Doing a cursory search on google resulted in no factual data. I'd like to get some kind of idea where it sits on the scale, although as I said, it is a terrible scale to use.

Yes so better buy a screen protector.

Why the interweb of course!
Most specific number I saw was 6.8 - but close enough, especially for a comparison using mohs.
Which isn't really a bad way to demonstrate is scratch resistance.
Everybody should know moh (ooh - I made a funny!), I was taught in like 6th or 7th grade. It always fascinated me for some reason.
I thought the whole point of the tempered glass protectors was to protect against head on impact. Will they really provide any benefit on a naked phone getting dropped on its side or back or corner?

I know sand scratched up my Nexus 6 (GG3) .took it to the beach :crying:
Um. Glass is glass, it can scratch and it can break. If this concerns you take $3 and buy a screen protector. I've run cheap plastic (not sure why people cover breakable glass with more breakable glass...) Protectors on all my phones and they always resale for top dollar due to conditions. Just protect it

I'm planning to buy a screen protector as well. I've never used one before so I guess I need a bit of your opinions here!
A friend of mine got some "high definition" foil protector on his HTC One M7. I hate it because it doesn't feel as smooth when navigating on the screen as it does without any protection.
Therefore I got the idea with tempered glass on my new phone, just because it feels like being "naked". I would prefer a protection foil though because of its thinness.
Is there any foil manufacturer providing a foil which feels like normal glass or something like that? I mean... Just like there's nothing on the phone?
Then I would probably going with this one.
Thanks in advance!

I'm completely in agreement - glass will scratch. Cheap protectors were all I used for a while. All I wanted was a disposable scratch deterrent.
BUT - the naked glass feel is so much better than plastic. I came to the point where putting a TGSP protector on to get that feel became worth the $ spent. I have no misconceptions on what it is there to do - disposable scratch deterrent. If I drop it and the screen cracks from a corner impact, there's nothing a screen protector could have done to prevent it, plastic or otherwise. Gotta be realistic about it, you know? It's not bullet/explosion/hammer/superman proof, despite the ridiculous advertising to the contrary.

I've used picks like those before. That seems valid. While the rest of the review is crap, imo, the hardness test is interesting as it shows a Mohs hardness of the GG4 as between 5 to 6.

Lol - I saw that. Only reason I did was cuz I get a laugh at how, and why, folks destroy something. It gets hits I guess, I'm sure that was its purpose, like many other smash this or that vids.
Mohs, with the picks anyway, is a pretty general test. I've used it many times in the field when trying to determined, in general, a rock sample.
For a device like a phone, all ya really need to worry about is what would be in a pocket or purse for the ladies out there. For the most part that's some sort of steel, or coin metal. Stainless ranges between 5.5 and 6.5, so as long as it's above that, we're good. An emery board in a purse would be disastrous.
Oh, and I'm seeing this often when referring to mohs. Many say, for instance, anything above a 7 will scratch a 7, we all know this to be true. The forgotten part is anything equal to a 7 will scratch a 7 - ie - diamond will scratch diamond, quartz will scratch quartz.
So in the video, gg4 appears to be between about 6.5 and 7. It is scratched by 7, but not by the blade, which I'll assume to be strong steel, say 6.5.
The stated 6.8 sounds about right to me.

Wait, think about that. The 6H pick did scratch the glass. It can't be 6.8 if a 6 pick will scratch it.

Watch the video again. It left a faint mark, but I didn't see any "scratch".
The faint mark was probably the oil resistant coating.
