INCREMENTAL said:Even tho they say they use gorilla glass I still thank its different then what Moto uses. I work in a machine shop and my OG Droid and Bionic has seen my work up in down and country life of being in the dirt all the time and have yet to scratch either but when I had the Nexus for a bit I put a fine scratch on it in no time.

Is the glass that's scratched our the coating?
The glass isn't "coated" in the truest sense that would be used to describe for instance a camera lens or prescription eyeglasses with an anti-reflective coating. It's more of a "doping process", where one molecule, atom or ion of a particular substance is exchanged for another. In the Gorilla Glass's case, it's the ions of Sodium (which are one specific physical size), are exchanged for potassium ions (which are larger specific size), and technically fill in the voids between the nearby atoms of the silicon, or more accurately sodium silicate (the primary element of glass), both making the matrix of atoms tighter and also leaving fewer and smaller indentations in the glass from which scratches start.
In thoery, if the surface of the glass were 100% perfectly free of any voids, then it would be nearly impossible to "scratch" since without an edge to catch the scratching abrasive and start the scratch process, the abrasive would instead simply slide across the surface like a wet foot on ice.
From Wikipedia (Gorilla Glass - Wikipedia, the free encyclopedia)
Manufacturing process
The glass is toughened by ion exchange. It is placed in a hot bath of molten potassium salt at a temperature of approximately 400 °C (~750 °F). Smaller sodium ions leave the glass, and larger potassium ions from the salt bath replace them. These larger ions take up more room and are pressed together when the glass cools, producing a layer of compressive stress on the surface of the glass. Gorilla Glass's special composition enables the potassium ions to diffuse far into the surface, creating high compressive stress deep into the glass. This layer of compression creates a surface that is more resistant to damage from everyday use. Like all glass, Gorilla Glass can be recycled.[SUP][9][/SUP]
Corning manufactures Gorilla Glass in Harrodsburg, Kentucky (USA) and in Shizuoka (Japan).
So you see, it's not really a coating but instead becomes a physical and chemical part of the composition of the glass at the surface. This surface layer transformation is deep into the glass (relatively speaking), so even surface scratches may not break through it into the unprotected glass substrate. Unfortunately any attempts to "buff out" or "polish out" surface scratches may remove enough of the transformed surface glass to leave a portion of the surface unprotected.
You are best to leave any scratches alone, or at most apply a polymer based scratch "filler", usually in the form of a light tan paste, which leaves a hardened residue of optical grade plastic in the crack and minimizes (sometimes even completely disguises) the scratch. This scratch repair paste is most commonly sold as a CD Repair Kit (available at Radio Shack), and works amazingly well, but most importantly is NOT ABRASIVE, so as to not do additional damage to the surface of the glass.
Finally, if a phone is scratched by you, do the right thing...suck it up and deal with it. Taking it back and claiming it was there all along in order to get it replaced free is dishonest and is frowned upon by the forum.
Actually, there is a coating that is applied by Corning to the Gorilla Glass if the company designing the device requests it.
Corning Gorilla Glass - Characteristics: "Easy-to-clean, wear-resistant coating: Customers can request Gorilla Glass with a special coating, making it easier to clean than other cover glasses – a perfect feature for touch devices."
Corning Gorilla Glass - Customization: "Easy-to-clean: Fingerprints and smudges can be a problem with touch devices, but Gorilla Glass offers a coating that is easier to clean than other cover glasses – perfect for touch screens and handhelds."
Most phones and tablets with Gorilla Glass have this coating, which is applied in addition to the process of manufacturing the glass that you detailed. The scratches that people see on the screen tend to be in this applied coating rather than on the glass.

It also results in several repercussions, including higher prices for future products due to reduced profitability or higher warranty insurance costs, stricter return policies as these dishonest methods (loopholes) of skirting the system are discovered by the retailer or manufacturer and closed off (which then hurts those who are returning items with honest and legitimate claims), and can ultimately result in someone at the customer service counter losing their job for making an executive decision under pressure and without proper authority.
taihard said:So you're saying that the OP should spend hundreds of dollars on a phone and do nothing wrong, save maybe having a sand grain in his pocket but other wise do nothing that that should have caused a scratch yet the device got a scratch on it within a matter of hours after purchasing it but he should just suck it up?! I think that perfectly warrants a trip back to the store to exchange it! No device costing so much should be able to be so easily scratched. And I'm sorry my other post (Deleted already) sounded so dishonest. I truly thought there was no way I could have put a scratch on it but then after exchanging it and the same thing happening I did realize it was probably my fault and so I am sticking with the phone I have now. I also said "use a little elbow grease" which I didn't mean. I did not "buff" it out, I used disposable electronic cleaning cloths and just cleaned it (which I suspect just removed finger oils or whatever else from the hairline crack thus reducing its appearance). After cleaning it to reduce its visibility and then placing a screen protector over it, you can't even tell it's there. So yes, you should not be dishonest nor should you be rough when cleaning your device, I'm sorry my previous post sounded like such.

Most of the time, those are not even scratches on the glass itself, but scuffs to the coating on the glass.Well that may be true but I know whatever they used on the Nexus was not the same as the Bionic/Razr. I don't even have to be careful and no scratches but that Gnex had minor scratches n a weeks time.
