Just how strong is the Gorilla Glass?

This video made me tremble the whole time.

oh man, it lasted A LOT longer than I thought it would...
I have to admit I cringed as well though.

I jabbed mine with a ballpoint pen about a week after I got it. The screen is still flawless.

Yeah, I just wanted to test the glass. Needless to say, I was not disappointed.

Not too bad, but i have seen some people say that thier phone got messed up while it was in there pocket. So this totally contridictes what they said

I recently dropped my phone from 4-5 feet on its screen. The digitizer behind the glass cracked rendering the screen all wonky, but the glass remained perfectly intact with no scratches or cracks.

I accidently put my phone in the same pocket as my keys and my screen is still flawles My case however has messed up the edges of the plastic part.

I've had my Cappy about 3 weeks now. I do not have a screen protector and keep my phone in my pocket, but never, not even once, with keys, coins, etc. In clear light with the screen off I am starting to see a bunch of "micro scratches", presumably from the fabric of my pocket and whatnot. I'm really starting to question whether or not I need a protector.

You definitely want a screen protector. I got am amazing amount of scuffing on the screen after only 2 days of living in my pocket (no metal, just cotton). Fortunately, I had other reasons to return that one and put a protector on the new one. Flawless after 2 weeks.
For a few $, why not?

Fml...

Cracked my 2 day mytouch 46... Any way to use the manufacture warranty

How did you do that? Was the screen glass?

It's not Gorilla Glass. HTC doesn't use Gorilla Glass *someone here suggested they did for the MT4G, they didn't*

Well Iguess its not glass, either way cab I still do manufacture warranty or is it only for software

That's some pretty hard carpet you got there. Man up! You dropped it on the floor.
Sorry to hear that.

No if I dropped it on the floor I would of said that, no point in lieing. I have no scratches just a straight line on the the screen

First, i would install some under padding at your place. Second, do you have the $5/mo insurance on the phone? That will help you. I don't know what to say otherwise but I'm truly baffled on how dropping it on carpet busted your phone. Did it bounce off a tall stairwell first "Brady Bunch" style?

did you get the protection plan with the phone. it's 5.99 a month? with that plan you can get a new one no matter what... without it your SOL

It fell from out my pocket while i was siting on my computer chair. I was naturly pissed the fu#% off seeing how it was not that high I have the insurance but it will cost 130 just to replace a cracked screen.. Was wondering if there was a chapter method

Suggestion for you, sine you have 14 days to add insurance do so and report a claim. manufacture warranty will not cover drops.

I know it's not gorilla glass but geez, a drop to the carpet = cracked screen?
How high of a drop? How hard was the carpet?

Wow...that sucks...on carpet none the less. Did you roll over it with your chair?
The reason I ask, is the very day I got it and was at home that evening, I had it on the bar in our kitchen because my daughters were looking at it...they got to messing around and my oldest daughter pushed our youngest. when she fell off the bar stool, she flung her arm and hit my phone off. It flew across the kitchen, bounced off the cabinet door and fell screen down on the ceramic tile floor. The battery door flew off and I completely expected to be making a post like yours for sure...my daughter picked it up, put the battery cover back on and put the phone back on the bar face down. As I was in the middle of cutting chicken, it took me about 5 minutes before I could go look...nothing at all, the phone is in perfect shape, no evidence of a fall at all.
I guess all it takes is one well angled drop to either be the end or the saving grace for any glass screen

Sorry to hear about the drop. Asurion is the 3rd party insurance and it's $4.79/mo on my bill, plus a $150 deductible for physically damaged phones. They'll ship it out to you next day usually.
You can also go back to the Tmo store and plea with them to exchange it. Maybe they can say that they dropped it or something like that. Good luck!

It's Gorilla Carpet! It probably hit where the most weight of the phone had the most impact and made it most vulnerable.

Actually I'm suspicious that your phone's screen had a fracture in it when you got it. No matter what kind of glass it is, it shouldn't have cracked so eaily. That would be my argument to the retention department when I wholeheartedly threaten to cancel subscription for making me pay for a phone that obviously had a flawed screen out of the box. Be firm, honest and be respectful. You just might get a replacement.

Are you sure it is a crack? Are you sure it wasn't there when you got it? I'm not even sure it is possible to crack glass from that height onto carpet without some sort of preexisting defect...

Screw honest, if the fall on Carpet did no exterior damage, go in there tell em there is a crack in the screen. Especially if your in your 14 days and you want a new one.

Having absolutely NO exterior damage might allow you to play innocent and ask for an exchange at the store. If that doesn't work, call retention.

Screen toughness

Ok, so I decided to be brave, well kinda. I have to send my mt4g back for a warranty replacement so I decided to see how scratch resistant the screen is. I first took the edge of the metal micro usb charging wire and tried scratching the screen with that, didn't work. I then went and took my keys held one key and started scratching it against the screen (like you would sharpen a knife) nothing no scratches. Tried with harder pressure... still nothing.. then took the whole set of keys and swirled them around the screen to simulate them being in your pocket bumping around.. I put a pretty good amount of pressure.. and still nothing! It did scratch the chrome bezel a little around the screen it did not make a single mark on the screen. For not being gorilla glass the glass on the mt4g is pretty tough. I was impressed I couldn't scratch the screen... I was just trying to see how well it would hold up in a everyday situation like having it in your pocket with your keys. I just tried again hacking at the screen with a key, harder than any other time before and still not a damn mark!

From what I was reading it's not gorilla glass but it is a high tempered glass. I really tried to scratch this thing with a key though. I continued trying even after this post. Still haven't been able to make a mark on the screen with a key.. and I'm not being delicate by no means.

Glass is pretty tough. And metals such as keys won't scratch it as its much softer than glass.
I don't remember much from geology class but there's a few rocks that can actually scratch glass.

graffixnyc thanks for providing us with actual BRAVE data lol guess we can rest easy now. I always knew it was using high tempered glass and was scratch resistant just keep in mind it doesn't mean its scratch proof

Yeah, I wouldn't take it and slide it across the sidewalk on its face but its good to know that its pretty tough and that having your keys in your pocket or something like that wont scratch your screen. I honestly don't see a point in a screen protector for this phone after this. I mean anything that's tough enough to scratch the screen would probably rip through a screen protector.
I tried really hard to scratch it with the keys and nothing, even after this I kept trying and no dice. I'm pretty sure sand or something like that could probably scratch up the screen but its good to know in average situations your screen is safe.

this is sorta on topic...while the screen may not scratch very easy...the damn thing shatters with the smallest drop it would seem
was just at my local tmobile store and while i was there i was playing with a g2 while waiting for my paper work and next to it was a guy looking at a mytouch 4g...well we started talking about how good the phone was...turns out he had just bought one and was waiting for the girl to come from the back and give it to him
so myself and the other dude walk to the counter together talking about the phone...i grab my paper work and as i do the girl goes to hand the customer the phone and she drops it on the counter and the screen just shattered from top right edge inwards...was pretty gruesome...it was a fall of maybe a foot to a foot and a half
im pretty sure that phone had to have a weak spot or something in the glass...cause there is no reason that screen should shatter like that from a foot drop...needless to say the store manager saw what had happen and told the girl to get the customer a new phone from the cabinet
i can say now though im going to keep a tighter grip on my phone from now on

Lol freek91 that's another thread of its own. But believe it or not I saw first hand like you how weak it is as I saw my friend drop it from his lap and thing shattered badly but it worked. I read similar feedback online that's the reason I am very anal about getting firm grip always and wasted $50 on case...
Sent from my HTC Glacier

if you drop the device, there is great chance to crack or even shatter the screen, and moreover, if you slide it over the surface of concrete, I'm sure the silicate/siliconate will have a great chance to scratch your screen.
The point is: take a tight grip of your device!

broke my screen, replaced it for $30.
Touchscreen is easily broken due to stiff frame.
Using TPU case makes it almost unbreakable....drooped in case several times from approximately 5ft onto concrete with no damage.
Get TPU case...run about $5 and look good

I'm on my 4th one, due to the SF vs. SO issue, and my first one's screen got scratched in spite of being in the babying period. Not in a bad spot, but 2 clear small scratches that would be a problem if in the visible part of the screen.
So I didn't find the screen to be scratch resistant (maybe the SF and SO are different), so when I got one with a good screen, I put a protector on it. Which helps with fingerprints, too, so that's a win.
I wish it was gorilla glass. I had the Vibrant for 14 days and it really seemed to have a strong, scratch resistant screen (and, dare I say it, a vibrant screen).
Just another data point.

No Screen Protector.

I took out my Mytouch last night and started playing games and noticed how smooth the screen felt. It took me a while to notice that the screen protector had come off.
I needed to replace it anyway since the top right corner was loose and dirty. Just a little story I wanted to tell. Does anyone else use a screen protector?
Sent from my HTC Vision using XDA App

I used to. I would always make sure I had a screen protector before i even got the phone so I could have it on on day one. But I recently took off my sp and noticed how great and clear and responsive the screen was without it. I've been rocking it naked for almost two weeks. Not a single scratch. Basically, with all of these glass and gorilla glass screens, you don't really need an sp unless you are putting the phone in a purse with keys and change or in a pocket with other items. I always have my phone in it's own pocket and keep nothing else in it. Haven't experienced a scratch. Don't think I'll ever use an sp again.

I thought MT4G owners said this phone gets dusts under the screen and spots, so wouldnt a SP be helpful here?

Naked since I tired of it after my first week! Months without one and not a single scratch...

Ive had a screen protector on mine since day of purchase, the guy at the tmobile store put it on before turning on the phone. I did have a sp-less HD2 that was mint and never had any scratches. the screen was very smooth and a tad bit more responsive. I think when I get my replacement mytouch, itll have the naked screen

I have a screen protector and a TPU case. I have it just in case. You never know what can happen. I feel like I can be a little less carefull with the phone with the cover on the screen. For example if im working on my car and using my phone to play music I can touch the screen with my dirty fingers and not worry about dirt and grime putting a scratch on it. Just wipe it off at the end of the day and its perfectly fine.

no screen protector is just so much more awesome.

It's kind of like having sex with a condom. Sure it still works while using protection but it feels so much better without it!

LOL never heard anyone put it quite like this in regards to a phone, but somehow it works and makes perfect sense!

I carry my phone in the T-Mobile leather sleeve so the screen is always protected and therefore I don't bother with a screen protector. My buddy doesn't use a case and therefore does use a SP, and the difference is noticeable. His screen is much less responsive, and it's more difficult to drag your finger across it.

I'm using a SP about a week and after that, I decided to take out to use a flip case for replacement.

Same here. no screen protector since day 1 and no scratches whatsoever

Story from my Nexus One. I had a Zagg shield basically forever, but the case I had did a number on the edges. I was getting close to getting a new phone, so I decided to just take the protector off and go naked. I figured, in my pocket, what could happen?
Within a day I had a nice scratch at the upper edge of the screen. Non in the "display" area, so I suppose that's good, but still not great for resale. I should be happy though that I haven't had any other issues.

lmao condom reference!

Some days ago I put the phone in my pocket and since I was in a hurry I forgot that my keys were inside too. After playing handball for some time I take the phone out of my pockets and notice this huge and deep scare right in the middle of the screen. I almost cried, really. But when I took the screen protector off, guess what, it was like new!
So, screen protectors dont feel as good as naked but at the end of the day you will be safe.

Naked since new, no scratches. SP's are a waste of money on most new devices with gorilla glass or scratch resistant glass.

Gorilla Glass or other high tempered scratch resistant glass can still get scratch. All you need is the right grind of sand in your pocket or right angle of impact from key, ect. SP only costs like 10dollar and high end like DQC/Crystal based is like less than $20. In the long run it pays for itself just stay out of InvisibleSHIELD BS but when you do get scratch you will beat yourself crying why didn't you spend $10. As having scratch on the screen does impact the resell value of the device.

Yes, it does get scratched. I haven't the slightest idea I got my scratch since I always have it in my holster... But the color and response difference has kept any screen protector off my phone since january. I'd rather have the vibrant colors

[Q] Dropped phone and it cracked the screen...how do I replace the screen digitizer?

There are replacements on Ebay but none come with instructions. Does anyone know how to take it apart and replace the screen?

Look it up on YouTube. I did it on my first EVO, and I must say, it was quite easy. It might be a little different for your device, but if you have even a little technical expertise, it shouldn't be a problem. WORD OF CAUTION, though. There is adhesive under the digitizer/top screen, so use a heat gun, or hair dryer, to loosen it first. It is like a box shape all the way around under the digitizer/top screen in a thin strip.

I haven't found any teardowns online, but it shouldn't be too hard as long as you have patience and be extremely careful. It looks like once the battery cover is off, there are 4 or 5 screws that you'll need to remove. Once that panel is off you should be halfway there. Just be careful because you're now in the belly of the beast. It would also help to take pictures along the way in case you need to know what goes where when re-assembling the phone.

gorilla glass?
might be a stupid question... but what happened to the gorilla glass?.. i.e. how high did you drop it from, etc.

Anything on this Earth can be shattered by different frequencies and impact. Gorilla Glass doesnt break if its from YOU pushing it in and stuff..Not from drops.

Try cnn.cn if they sell the part they'll have a guide.

Gorilla glass is scratch resistant and shatterproof; however it's still glass. Same principal as "Water Resistant" phones or items, you can't submerse them, but you can get them wet.

Slipped out of my hand while getting up off a chair, fell about 2 feet, landed flat on the glass side onto some tile. Heard a pop sound on impact. It shattered the bottom corner.
I've owned several HTC phones with gorilla glass and this is the first time something like this has happened. I think the fact it has a aluminum housing has something to do with it. Plastic housings can flex a little on impact. Aluminum doesn't flex as much and since glass can, it caused the screen to shatter since the energy had nowhere to go.
Definitely getting a Casemate or Otterbox (if they release it) once I get the digitizer replaced.
I've been looking all over for a tear down but no luck yet. I might just have to wing it and try doing it myself with one of the kits on Ebay. I really hate having to go in blind.

Can you not get it replaced on insurance? I feel for you buddy!

Cnn.cn does have them, probably more reliable than ebay. great opportunity to makes the first guide!

I would buy from cnn.cn here.
Unfortunately they do not have a video up yet but seen as they sell the part, and if you buy it from them, you may be able to request it from them. Worth a try.

i know it can break. its just supposed to be harder than normal. i just wanted to know if it was from a "normal" situation or something out of the ordinary.
will definitely get an otterbox as well. if they ever come out with one..
2 feet drop on tile is how i broke my iphone 3g :/

I know it's not the same as our phone but the steps should be close enough. Here's a teardown video that engadget re-posted today of the EVO 3D http://www.engadget.com/2011/07/01/htc-evo-3d-torn-down-three-dimensional-magic-revealed-video/

I know this thread might be dead but the cracking of the screen happened to me too. I was wondering if anyone knew of a guide or could give me some tips on how to replace the digitizer since I will be attempting to do it myself.

Can you post a pic. Of your broken phone? I would like to see what kind of damage a 2 foot fall made
