Gorilla Glass Better Explained

Gorilla glass is a glass that is stronger than normal glass. Normal glass is usually made with soda/lime as a stabilizer/fluxer / formers.
Basically, Gorilla has a harder surface than normal because of the Annealing process (heat and cooling process to relieve stress in the glass and make the surface a harder surface)
Because of the process it make Gorilla Glass Ideal for cell phones and alike because:
1. It is lighter because it can be thinner
2. Its surface is harder than traditional glass so it is more resistant to scratches.
3. If has a greater modulus (more elastic) so it can take more flexing without failure.
Of the 3 above Weight is the major driving force for the Gorilla Glass use in a cell phone. The Vibrant has Gorilla glass as All Galaxy phones use it to make the phone lighter.
Below, for you techies types are the basic short explanations of the glass additives.
►FORMERS are the basic ingredients. Any chemical compound that can be melted and cooled into a glass is a former. Silica (sand) is the most common former.
►FLUXES help formers to melt at lower, more practical to achieve temperatures (1300°C or 2370°F). Fluxes include Soda Ash, Potash, and Lithium Carbonate. However fluxes make the glass chemically unstable. Therefore;
► STABILIZERS combine with formers and fluxes to keep the glass uniform and keep its special structure intact. Stabilizers include Limestone, Magnesia, Barium Carbonate, Stronium Carbonate, Zirconia, and more.
► ADDITIONAL OXIDES are used to impart color, for example cobalt oxide turns a melt deep blue; iron or chromium oxide turns it green; gold changes it to a light red. Other oxides are used to decolorize, opacify, or control important characteristics such as expansion rates and optical properties.

cool story,

Whoa, thanks. Interesting read.

Yeah, thanks for this.

Nice read. I could even see it through the crack in my screen.

Glass is still glass
Remember Glass is still glass raising the threshold of fracture and scratching is great but, the RF (fracture resistance) though raised glass still breaks. one day we will have clear carbon and THEN we will no more fractures

Screen cleaning tips...

Everyone knows that humans are basically disgusting oily creatures. As such our SGN10.1 screens get very funky very fast.
I have tried many different methods for cleaning my screen. Here is the one I have found by far cleans the fastest and the best:
Simple rubbing alcohol on some TP, wipe then clean off with a clean peace of TP.
- - Some folks have advised me against this due to the coating on the screen. I will consider other options.
For me this instantly puts the screen in super clean, just out of the box condition.
* I haven't found anything yet that truly prevent finger funk attaching itself to the screen. Tried Rain-x etc but found that tended to leave a slight haze.
Any other ideas?

So the best place to clean it is while filing paperwork in the office?
Sorry, I just use a microfiber cloth to wipe my screen down.

I use those Zeiss lens wipes you can get in a bulk pack at Sam's for like 10$. It's a box of like 500 of them. I used them for everything from glasses, to cleaning my S3 screen, to cleaning my tablets and even the back and cases for all my devices. Works great, handy, cheap, safe. Go get a box.

I use a microfiber cloth, I think it is the best solution, as other material easy can scratch the screen (micro scratches)

why not just cutting the paper tissue in half, one half for wetting and the other half for drying.
water is gentle on the different components and does the job.

Magic spray glass cleaner in a aerosol spray can it's a foam cleaner and resist dirt and poly films. You can get it nearly everywhere like home depot and auto parts stores.use of for bathroom mirrors windows computer screens and our touch devices. Ohh and car window's what its made for. Invisable glass is another equal in quality

Ditto. Best thing I've found. If I have a bit of something to remove that the cloth alone won't handle I turn my Note off and wipe the gunk off with a very slightly dampened corner of the same cloth. Dry the screen thoroughly and I'm back in business.
It is not recommended to use cleaners due to the screen coating and the need to preserve it.

matte screen protector goes a longggg way. No oily residue, no cleaning, no glare

I use acetone on thick-grit sandpaper... if the fingerprints still don't come off, I just replace the glass with some plastic wrap from the supermarket; cheap and they sell it by the roll.
Honestly though, I have this problem and was thinking about using rainx. For now, I just sit there for 5 minute pushing down on it with my shirt

I have found that a little moisture and a micocloth works best but I have also found that it cleans much better if you use a soft touch like you were polising it rather than trying to wipe off the fingerprints etc.

Exactly.

I using normal cleaning spray for LCD display. U can found it easy in computer shop. But i found much better cleaning detergent by using spray detergent for cleaning window/mirror, we call it "magic clean" spray. Much cleaner n easy to clean by single wipe. I try to give link, but could not found one. Its just a cheap clean detergent
P/s: did i forget to mention, im using screen protector

Alcohol is an abrasive material. It creates millions of micro scratches. It will for sure remove oil due to its abrasiveness but for sure is taking away stuff it doesn't need to - the protective quoting digitizers come with. There are spray fluids to clean glass surfaces like those use to de-oil and de-fog your sun and eye glasses, and this contain a miniscule concentration of alcohol among other agents but for not as much as the 70% present in rubbing alcohol.
I tried alcohol way back when I started using eye glasses and I noticed that after a while the glasses picked up some sort of fogginess that never came out even after trying soap and what not - that's the millions of micro scratches I was talking about.
The advise by the other member to tear a paper tower in half and wetting with WATER and drying is the best advise IMO (and past experience).

Well, that no alcohol warning comes primarily from Apple because the new iPad has an oleophobic coating on the screen to prevent smudges. I do not believe our Note has that coating. If it does it sure is doing a lousy job. I honestly do not believe alcohol itself is abrasive. Nevertheless I will check out some of the glass products at the hardware store to see what they have. I have tried glass cleaners before and they left the screen foggy and smudged.

Digitizers come with a protective coating.

Ok well whatever coating it is doesn't prevent finger smudges worth a damn. I'll look at some other products.

Alcohol is only abrasive like a solvent in that it can etch some materials or remove coatings but it is not abrasive like sand or grit.

I used Auto Glym glass polish and it worked a treat. Though I don't think it would be good as it probably contains a mild abrasive. Though it did work wonders. I now have a screen cover that I wipe over gently with a microfibre cloth.

Yes it does have an oleophobic coating, if you'venscratched your screen, its in that coating. Gorrilla glass really is nearly unscratchable

Does the S4 Screen have Oleophobic coating?

I love the feel of the Gorilla glass 3 screen and it does not attract fingerprints easily. I just put on the Spigen Ultra crystal and it attracts finger prints. I know with Oleo coated screens the coating wears off after awhile and its no better then having a screen protector. If I know there is no coating that will wear off I may just go without the screen protector.
Thanks

there is a coating.

You can re-apply an oleophobic coating to the stock screen anytime by using this liquid applicator product:
http://www.amazon.com/API-Fingerpri...TF8&qid=1368569876&sr=8-1&keywords=Oleophobic
Reviews are mixed.
Price is a little high.
But... it's an option.

I love it for the fact that it doesn't leave finger smudges...
I hate it for the fact that it's so slick that my phone sometimes detects a swipe when I am trying to select.

can you use this on screens that are not originally oleophobic?

This product looks pretty similar to rain-x in use. I don't know if anyone has tried that before on a screen, but it should have a similar effect. If I didn't use a screen protector, I would try it out. It makes my car windows super slick to the touch once applied.

buying a g6 with broken camera glass...

Getting it for 200aud..
Can replace the glass piece for about 10 off eBay.
My question is how tight that area is in general in terms of the ip68 rating, consisting that the "glass" is just an adhesive. I.e. is the rating still intact

if you only replace the glass from the camera and if you replace it with the ORIGINAL part, then you will have the IP rating the same way, BUT...if you buy cheap glass with cheap adhesive...i didnt know how it takes the IP at same level, and how long it will take to lose the glue and maybe crack again.
Better safe than sorrow...
see this: https://www.youtube.com/watch?v=6qfQ1TH_KBs

It's very tight. I bought one for a 3rd the price of new the glue was discolored, but the glass was otherwise ok.
Love Jerry's Videos. But he'd already removed that lens, and had an appropriate crack to help leverage up a piece of the glass. I couldn't even get a scalpel blade under the edge let alone a box cutter, I'm quite dexterous. Before I replaced mine I watched someone jam a spudger down there to get it out. Maybe my spudger wasn't thin enough but I could see the main back glass flexing while I did it so I tried something different..
I realize yours is pre-cracked, but just detailing everything I did.
What worked for me:
1) apply just enough force between the lens and the edge, you want a crack to extend outward to the edge, but avoid having dust near the actual camera lens. Saw a video of someone puncturing a hole right where the camera lens is - not smart if you like clear pictures.
2) clean all dust now!
3) take out a shard from the edge with tweezers being careful to not puncture the tape on the under side
4) heat lens then apply a cut and shaped piece of tape on top of the lens to hold in any dust when you peel.
5) place tweezers into the edge in the hole you made where the shard was, try not to put pressure on the back glass - mine was surprisingly tough, ymmv.
6) peel the edge of the under tape slowly upward try not to bend much or the glass will make a ton of dust.
7) vacuum and use compressed air around the opening.
Hope that helps.

Thanks for the comments. New glass arrives tomorrow so I'll be going through the process then. Seems pretty straightforward, but yes, probably will avoid submerging it etc just to be safe.
As far as cleaning the lens, I will use acetone (cotton balls) and compressed air. Good?

No acetone, just alcool

Just an FYI: Thin solvent liquids like alcohol will seep in the gap between the lens cover and the glass back and onto the sticky reflective tape discoloring it. I've seen it a bunch of times with the G6, the effect is worse with replacement lens covers as there isn't any adhesive on the edge.
If I was to redo this job, I'd consider using some B-7000 applied with a tiny brush around the thin edge of the lens cover to seal it. Once dry I wouldn't be concerned about cleaning with alcohol. Maybe depends how obsessive you are lol.
As always YMMV, hope the replacement goes well.

What adhesive or glue should I buy to repair the split between the lcd and the rest of the digitizer frame?

I noticed a white light on one side of the screen wjile I was using it. It was leaking from the back of the lcd. There is nothing wrong while using it so far.

Using the OEM method be best. A picture would help.
LCD displays are vented on the sides to atmosphere. They are very susceptible to solvent poisoning; keep all solvent and vapors away from the display!
Do not use super glue or Gorilla glue. If far enough away from the LCD edges you might get away with Gorilla glue using a fan until cured. Epoxies and silicone seal same deal.
If it originally used double sided tape, use that!

Here are some pictures of how the glass/digitizer/lcd panel is separating from the rest of the frame. Based on iFixit, it would be best to use double sided tape.

Did it take a drop or get flexed?
Is the frame rail still straight?
If frame rail is still straight it can be reseated. It looks like double sided adhesive tape, inspect it to see if this is true. If so the whole panel needs to be pulled, cleaned and new tape of the same thickness reapplied. If a OEM part is available use this instead.
Surfaces must be clean and oil free. Carefully use anhydrous isopropyl alcohol to degrease and clean. Make sure none of it contacts the sides of the LCD!!! Use a fan so vapors don't build up; if poisoned it will trash the display.
Watch some tear down vids as they can be very helpful.

Check frame rail with a straight edge to see if bent. That can cause an adhesive failure.
