    Default Does the screen scratch?

    So I decided I would try my N5, as my first phone ever, to not apply a screen protector to. I work an office job, and my phone is always in its own pocket facing my leg with nothing else in it. Never dropped, and well handled.

    Phone had smudges and what not, so I took my Diztronic TPU case off (only protection I have) and wiped off the dust etc with a Micro-fiber cloth.

    After everything was nice and clean, I looked VERY HARD to try and find any scratches, and I noticed 2 very small and extremely light scratches on the screen. I mean you have to look EXTREMELY hard to find them, but I guess even with my use which I wouldn't deem at all rough the phone is still able to get light scratches with Gorilla Glass 3.

    Doubt I can do anything about them, and they really aren't that bad for me to really care, but just a PSA for everyone out there. I still am not going to put a screen protector in it as I can live with scratches that are this light (I'll probably get whatever Nexus is released next year anyways) and I am still curious to see how well a screen holds up after a years use w/o a screen protector.

    I have two small scratches after a couple weeks use. Kinda gutted but they cant be seen once the screen is on.

    Same here, I used to be SO ANAL about things like this but lately I am starting to calm down. They are barely noticeable and at the end of the day, the phone still looks damn near brand new and works exactly as it should so no need to fret.

    Gorilla Glass is not a magic shield. The screen can still get scratched. It's just harder to scratch it. There is no phone made that is invulnerable to scratching.

    All phones are hard to scratch nowadays because they all have glass screens now. And glass is a lot harder to scratch than plastic in general. You may have had sand or dirt in your pocket. One thing that will still scratch glass is rocks, even small ones.

    I generally do not use screen protectors, because even if they are immaculate when you put them on, they quickly become less so. The cure is worse than the disease. The only way I'd use one is if I was very very concerned about resale value and did not care if my display quality was impacted.

    Basically Sand (most rocks are made of sand) and Diamonds will EASILY scratch glass.... Metal is more likely to chip it than to actually scratch the surface any... I've had my Nexus 5 since the Monday after launch and the screen is still flawless... but my GS3 had a couple of hairline scratches you could only see with the screen off and it freshly cleaned spotless.... Heck you could only feel those scratches if you drug your finger nail across the screen with good pressure on it... outside that you'd never know it was scratched.... I just like the basic feel of the raw glass vs any screen protector.. Not to mention spending money on something that isn't 100% needed... I'd say if you are clumsy, work in a dusty dirty trade then yeah put one on there.. If you got an office job and rarely break a sweat your probably not going to scratch it.... or at least not bad enough that you'd really notice (Unless you have serious OCD... lol)

    I'm putting a screen protector only for an upcoming two-week trip to Hawaii. After that, back to naked.

    I have scratched two phone screens in the past several years. Those were the Nexus 4,and 5. This is the part of buying a Nexus that sucks- Accessories. Despite apparent sales success right out of the gate, these devices are barely blips on the average consumer's radar and thus receive zero accessory support in store. We all end up having to wait on ordering things like screen protectors.

    I was debating getting a rhino glass screen protector for it, but I'm going to try to get away with a case with cover instead. I still might change my mind depending on how I feel about the case.

    i usually buy a large laptop screen protector and cut it myself for all my little screens.

    glass, gorilla or not, has a mohs hardness of about 5-7, many thing can scratch it, especially our whole world is mostly made of silicates, most of them are just as hard, if not harder. Particles with small sizes are especially dangerous, because they have small contact area with the glass, so the pressure per area increases drastically, which lead to scratch.

    I have a bunch of tiny scratches on the right side of my screen. No idea how they got there as my usage is similar to yours, digink#AC.

    I did order a pack of Spigen screen protectors from Amazon that should arrive tomorrow. I haven't had a screen protector, or a scratch, on a phone screen for years. We'll see how they do but I have a feeling that I will not like having a protector.

    Tempered glass screen protectors don't suffer the 'normal wear and tear' or display transmittance issues to the degree that 'normal' film SP's do. In truth, they feel just like the actual glass because they are glass, and hence also don't yellow or stretch, and allow a much higher% of light through.

    There are tempered glass protectors rated at 9H, which are far more resistant to scratches. But as you said, nothing will be fully impervious (especially to something as simple as a grain of sand).

    ...., actually those are not mohs scale hardness, those are pencil hardness and not really that much better than GG. The vendors are playing number games with consumers.

    Never seen an OEM refer to it in terms of 'pencil hardness,' whereas some have been quite specific to Moh's...

    Example: Amazon.com: Tesla 102 Intension Panel (The World's Strongest Protection Glass) for iPhone 4/4S: Cell Phones & Accessories
    Mohs Hardness Scale measurements for the surface hardness of GLASSIL in the Tesla 102 Intension Panel is 9H, which is more than two times the hardness of standard LCD Protection film (measured at 4H)
    It's a pretty safe bet that any of the reputable manufacturers that list a _H rating are providing it in Moh's scale - otherwise.... they wouldn't keep that reputation (imagine if an auto manufacturer promised over 100 MPG fuel economy, and later said "well we meant 'meters per gallon'!).

    So something like http://www.amazon.com/Spigen-Protect...0-20&m1k=vb_ac would be worth considering (though they are not cheap) if you want equal-to-better finger-facing scratch resistance while providing full scratch protection for the actual screen with insignificant impact on brightness, color accuracy, and maintaining that performance over an extended period of time without wear-and-tear degradation, all while providing a more oleophobic display. (Or, the GLAS.tR model if you won't be using it in a case)

    Gorilla Glass 3 will scratch is you use a Diamond tip to scratch it.

    So something like Amazon.com: Spigen Google Nexus 5 Screen Protector Glass Slim [Crystal] (0.15mm) Thin Lightweight 9H Hardness Tempered Glass Screen Protector Clear for Nexus 5 - GLAS.t NANO SLIM (SGP10666): Cell Phones & Accessories would be worth considering (though they are not cheap) if you want equal-to-better finger-facing scratch resistance while providing full scratch protection for the actual screen with insignificant impact on brightness, color accuracy, and maintaining that performance over an extended period of time without wear-and-tear degradation, all while providing a more oleophobic display.

    reputation is easy to keep if consumers know nothing about the science behind mohs scale hardness.

    First of all, mohs hardness has no unit whatsoever, diamond has a hardness of 10, not 10H, limestone has a hardness of 3, not 3H.

    The fact that the item description at amazon says something like "this is 9H, twice as hard as the normal one, which is 4H", already tells you its fake. On Mohs scale, scale 9 is 20 times harder than scale 4, not merely twice, the changes in absolute hardness between Mohs hardness numbers are not linear at all. https://en.wikipedia.org/wiki/Mohs_s...neral_hardness

    you know when they have that "H" attach to it? when they list pencil hardness scale, like this DNP Develops Surface Cover Sheet to Prevent Damage to Touch Panels | DNP [ Dai Nippon Printing Co., Ltd. ]
    or here https://en.wikipedia.org/wiki/Pencil...classification

    DOn't get fooled!

    Gorilla glass will scratch if you look at it too hard.

    Well I've certainly never been under the impression that screens or SP's were scratchproof!

    Here's a little information I found in pursuit of my own ongoing self-education - perhaps you can provide more insight:

    Gorilla Glass (original)
    Vickers Hardness (200g load)
    Un-strengthened 622 kgf/mm
    Strengthened 701 kgf/mm

    Gorilla Glass 3
    Vickers Hardness (200g load)
    Un-strengthened 534 kgf/mm
    Strengthened 649 kgf/mm

    Evidently there are different methodologies by which 'hardness' can be calculated, as it is possible for two items with a higher hardness rating on Moh's scale to be rated in opposite relative hardness on Vickers scale (source). As best I can tell, the Vickers scale demonstrates resistance to fracture (note that GG3 is less resistant than original GG); I'm not knowledgeable enough to review those white papers to determin which data (if any) might lead to a Moh's scale rating to gauge actual scratch resistance. Given that (from general web search) most steels are harder than 5 on Mohs scale, it seems safe to say that GG3 would merit at least a higher rating than that, since steel knives to do not leave scratches.

    General searches report tempered glass to typically range from 6-7 on Moh's scale, so it doesn't seem to be too hard a leap to expect Corning to have reached / extended beyond the upper end of that estimate.

    Good you are doing the digging! I have taught mineralogy so I know a thing or two on the Mohs hardness.

    The key is the unit, 649kgf/mm2 says it can take 649 kg of force per square mm before the crystal breaks (which result in crack or scratch).

    Now, the smaller the grain, the less the contact area will be. Applying the same force on a smaller contact area, will give much higher kgf/mm2 number. Sand grains usually range from 0.05 to 1 mm in diameter. With the fine sand at 0.05mm, the contact area would be 0.05*0.05=0.0025mm2, it can scratch the GG when you apply a force of 649*.0025=1.6kg, or about 3.5 lbs. Notice, however, a screen protector, even though may not be hard enough to resist scratch, its shear thickness makes sure the fine grain sands won't even penetrate it and reach the surface.

    The number for GG3 is very normal for a relatively pure quartz glass, it really is not that much "better". As many has witnessed, tiny sands are perfect for scratching it. Most sand are either quartz, or feldspar, both has comparable hardness of 5-7, at small grain size, they can easily leave some marks on a GG screen.

    I do believe scratch and impact are two different thing. The mechanism, momentum, contact area are all different. This thread, I think, is about "scratch". A dropping ball doesn't "scratch", it "smashes".
