[Galaxy Note GT-N7000 General] rdosti:
Confirmed:

Galaxy Note does not use Corning Gorilla Glass.

It uses fortified glass or tough glass (which may be called Gorilla for the sake of being strong).

Samsung and Google do not prefer using Gorilla Glass (yet) perhaps due to the lack of a concrete deal for some of there mobile devices (some do use it) . Corning had addressed this earlier that the Google Nexus also will not / does not have THEIR Gorilla Glass. They have taken the glass from another vendor that has not been publicly named. As a result the glass that you see on your screen is "Gorilla" (tough) glass but not that of Corning's.

Though Corning’s Gorilla Glass has all but dominated the review circuit when it comes to must-have features on mobile devices over the past year, it appears that Samsung and Google have opted for a different solution for their next hero device, the Galaxy Nexus. This device will play host to Google’s next-generation mobile OS Android 4.0 Ice Cream Sandwich and is set to have a host of powerful features that make it a force to be reckoned with. Corning has assured the public that lo, and alas, the Galaxy Nexus does not have Gorilla Glass sitting on its front.

When you hit the search button on the term Gorilla here in our archives on SlashGear, you’ll find that Corning’s ultra-strong glass formula appears as recently as the upcoming most powerful Android device on earth, the ASUS Eee Pad Transformer Prime, a tablet toting NVIDIA Tegra 3 quad-core chipset. What we must assume here is that either Samsung and Google had a special deal going on with a separate company for the glass, or they saw that Corning’s Lotus Glass would be the next big thing to have anyway, and opted for a nameless glass in the interim. Note in that Lotus Glass article that Rue suggests that its possible the high resolution has something to do with the switch as well.

Peek at a hands-on with the Galaxy Nexus next to the Galaxy Note here if you’ve not already, the Galaxy Note is another new Samsung device to refrain from having Gorilla Glass for one reason or another.

What do you think, do you need Gorilla Glass in order to have a great time with a device and not worry about it getting scratched? Have a peek at this hands-on with Gorilla Glass from earlier this year as well and see what it means to have nearly un-damageable fronts to your mobile devices. Heed the breaks.

iPhone 4s also I believe avoided Corning's glass.

The story of the iPhone using Gorilla Glass is like this -

In the 1960's Corning developed a chemical exchange process, which lead to the tough glass known as 'Gorilla Glass,' but Corning failed to find a market for the same and had quit making it altogether. Jobs jumped on the opportunity and offered to buyout all the Gorilla Glass that Corning could supply in the next six months, but since none of the plants that Corning operated were manufacturing this glass, the supply was in doubt. Jobs persisted and pushed Weeks to divert resources on the Gorilla Glass and eventually they were able to meet the demand in less than six months.

The first iPhone shipped in 2007 and the rest is history. It resulted in a mini-panic within the smartphone industry. While the entire industry jumped on the full touchscreen smartphone bandwagon, Corning made hay while the sun shined. Almost all smartphone makers looking for a good solution to strengthen their touchscreen ended up using the Gorilla Glass. We have seen the Gorilla Glass finding its way to notebooks and in all probability Apple might be using the same technology in its other product lines like the iPad and the MacBooks as well.

Wendell Weeks is quoted saying "We produced a glass that had never been made." And a prized possession that he has today is the memento framed on display, it is a message from Steve Jobs that reads "We couldn't have done it without you" ... sent on the day when the original iPhone was launched. Corning's website may not mention Apple as a client or the iPhones as a product featuring Gorilla Glass. Rather it features a long list of manufactures using the Gorilla Glass and dozens of products using the same. Apple's role was silent, away from public attention and never advertised. Yes Apple reinvented the Gorilla Glass, just one of the many small things that changed the face of the smartphone industry.
