Samsung S4 - Something under the glass cracked... - Galaxy S 4 Q&A, Help & Troubleshooting

Hello.
My phone fell from my pocket yesterday and it isn't working now. Its glass didn't crack, but I can see that something under it did and I don't know what. (When I turn it on, I can see just some stripes or colour pixels - mostly green ones)
So... Is it possible to repair it? If yes, how much would it cost? Is it better to buy a new phone?
Thanks!

The AMOLED display cracked, meaning you'll have to replace it. Since Samsung bonds the glass to the display, you cannot purchase the AMOLED display by itself, but must purchase it with the glass. You're looking at about 150USD for the privilege.
You can purchase used devices on Swappa for about that amount, so I wouldn't bother repairing the device and would get another phone.

Replacing gorilla glass.

I cracked my glass on my screen and purchased a replacement online. I've found tutorials on how to replace the screen as a whole but I only need to replace the glass. The screen is fine. Any info in this?
Thanks beforehand.
i dont know much about this in particular but u would have to open the phone up but u gotta be careful not to damage the touch sensors if you do replace it, or u could just sell it and put maybe 100 in for a used one
If you want to replace the glass, the Super Amoled itself will have to be replaced as well. Unfortunately, the glass and the amoled screen are glued together which makes seperating the two nearly impossible without tearing/destroying the Super Amoled.

Not true. i replaced mine on the second atempt, on the first i cracked the amoled.
I really dont recomend you to do it yourself. Let a professional do this for you, but if you are really studborn.. here comes the info :
the border of the amoled is glued to the glass. the trick is that the amoled, is so fragile as an egg shell, to be honest, more fragile. since part of the amoled is glued to the back of the phone dispositives, any wrong trie to pull the glass, can crack the amoled.
So you need a hot dryer, and a lot of time and pacience to remove all the glue before trying to pull the glass. if you did not broke the glass on the borders or over the buttons (back, home, seach, settings) i recomend you to not lose your time and send for a professional, because the shattered pieces will stay over the screen and you will not be able to clean the amoled without damaging it.
Sorry for my english, hope it helped, but the best i can tell you, just send to a professional or there is a 90% you will screw it like on my first time

Which is exactly why I said nearly impossible. OP would be better off buying a whole new screen or a cheap unit off of Craigslist.

Absolutely right! I remember the days I used to work as a cellphone technician repairing hardware damaged phones... a lot of people used to come to replace iphone glass.... people would buy iphone glass off ebay and have no clue how to take it off the screen...breaking the screen while doing so... and from my experience only a few!!!! a FEW!! technicians can do stuff like that.. you need BALLS and steady hands! and PATIENCE! google the topic she as much as you can find.
In other words from my experience you can try to sell your phone on craigslist for some change... and buy a used or stolen model for a low price! half of the phones on craigslist are stolen so ur not doing anything bad buying it, u just assume ur buying it for a good price while a thief tries to make a quick buck, just check the phone completely if it works... ear piece, speakers,, touch screen, internet signal,,, etc..
Good luck pal!
Unfortunate
Thats very unfortunate as a gorilla glass lens only costs 20 bucks whereas the entire display unit costs 100-140

Cracked screen replacement.

I have the LG Nexus 4 and my screen was cracked recently. I dropped it while jogging. The screen still turns on and the touchscreen works (only where there are not any cracks), so everything appears to be working still. I have been shopping around for screen replacements but there are so many options and the prices vary so much that I am not sure which to buy. I am looking for the cheapest option of course. I do not mind replacing the screen on my own. I have found prices ranging from $30 to $300. Most are in the $100 range.
I watched a video on youtube on replacing it and they showed the replacing of the front of the phone. Is that what I need? The entire front end of the phone (screen and digitizer) or is there a cheap way of replacing the glass only? If you could, could you please reply to this with any feedback/tips and perhaps links to some good replacements from reputable only companies? I would appreciate it.
Here are a couple that I found, though I do not know if this would be enough.

This is for the glass screen only.

Since you have seen and maybe researched many screens, can you please tell me which ones the most non reflective, yet budget friendly?
The biggest problem I face is that my screen is too reflective and seeing things in harsh sunlight is almost impossible with screen gamma / color /whatever it is tuning

The easier method is to replace the whole front panel which is also the most expensive. If you're thinking about replacing the glass only, you'd require to heat the glass from the display just to remove it because the whole thing is bonded by glue. Furthermore, I'm not sure myself whether the glass that they sell has it's digitizer with it because if I'm not mistaken, N4's glass is fused with the digitizer with (the zero-gap thing). I personally recommend replacing the whole front panel since it's way easier.

You don't.
Although it is entirely possible, the chance of failure if done by people with absolutely no experience with mobile phone repairs is very high.
If you've broken the screen on your Samsung Galaxy S3 and have considered replacing the screen by yourself because your local mobile phone repair shops charge a hefty price for the repair, you should reconsider. You may have seen videos like the following that make it seem it is very easy to replace the glass only:
(skip to 3:00 in this one)
Maybe it seemed too easy. That's because it was too easy. Chances are those screens have already been replaced before by a third party who has access to professional equipment and skills. Possibly the screen has been broken more than once?
Even if you do successfully replace the glass only, it is guaranteed that you will get scratches, dust, fingerprints and adhesive marks on the Super AMOLED panel, no matter how much you clean it. That's because you won't be doing the repair with gloves on in a clean room free of dust. And that's not all - after a few weeks or months of use, dust will somehow find a way to get in between the glass and SAMOLED+ panel because you didn't use machine-cut adhesive that adheres your glass perfectly, leaving no gap for dust to get in. Your screen's touch sensitivity will drop as well, since it's not making adequate contact with the digitizer. And on top of that, the visibility will also drop.
Those problems don't show up on camera, and can easily be masked/hidden from the camera, too.
If this is only your first time breaking the screen on your S3, those tutorials won't work for you because your screen was manufactured as one whole piece by Samsung. The glass on your phone won't fall out by itself because the whole glass is optically laminated to the SAMOLED+ panel using a Liquid Optically Clear Adhesive, or LOCA for short. This kind of adhesive is a little bit sensitive to heat, but can't be completely removed because it is cured using UV light, not heat.
Optical lamination is a manufacturing process employed in more high end mobile devices that eliminate the air gap usually present between the display panel (usually either LCD or AMOLED) and the glass digitizer panel on top. Phones such as the Samsung Galaxy S3, S4, Note 2 and Note 3, iPhone 4/4S/5/5S/5C, HTC One X, One, Butterfly, Droid DNA, LG Nexus 4, Nexus 5, Sony Xperia Z, Z1, Z Ultra etc. have displays that are optically laminated. Optical lamination has a number of advantages:
Visibility is increased (especially under sunlight), since there aren't multiple layers reflecting ambient light creating optical interference
Screen clarity is increased, since optical lamination makes the display look like it is on top of the glass as opposed to being under it
It is impossible for debris like dirt and dust to get trapped in the air gap between the display and glass, because that gap is filled with LOCA
Higher contrast ratio, because there's less light reflecting off the parts of the screen that aren't emitting light
But the biggest disadvantage is the increased cost of repair. That's what you have to pay for all those aforementioned advantages. It also certainly doesn't help that the screens are getting thinner and thinner every year. The likelihood of breaking the screen increases every year too.
Here's a little photo album that I'd like to share with everyone documenting my experiences trying to remove the glass from full original Samsung screens that haven't been replaced or tampered with before. Click to enlarge.
This is a picture of the Black Samsung Galaxy S3 GT-i9300. Only the glass was broken, so I attempted to separate it from the AMOLED panel using a heat gun and some plastic pry tools. So far so good, until the AMOLED panel broke because it is optically bonded to the glass and also stuck to the frame underneath it. You can still see some LOCA on the AMOLED panel and glass.
Second is the Galaxy S4 GT-i9505. It was broken on the top half, so I started removing the glass from the bottom. Again, the LOCA wasn't very cooperative, staying quite solid throughout the removal. Eventually, the S4's AMOLED panel broke too.
It didn't look like the broken original Samsung screens wanted to be separated, so I moved on to fully intact screens.
It was a pain trying to separate this one. The adhesive was very difficult to remove, and the screen's touch digitizer circuit and polarizer started to separate from the AMOLED panel. As you can see, the glass came off intact, but the AMOLED underneath was completely destroyed.
It doesn't look like the digitizer circuit/polarizer is bonded to the AMOLED. It just gets sandwiched on top, so it is very easy to unintentionally separate it from the AMOLED instead of leaving it on and only removing the glass, especially if the glass is smashed into a thousand fragments. The glass was in one piece though, and you can see how that turned out.
This is a good representation of what the AMOLED sandwich consists of. From top to bottom:
Gorilla Glass
Touch digitizer circuit/polarizer (you can see the rest of the glass is a lot darker than the top left corner where polarizer was removed)
AMOLED panel (it looks very reflective without the polarizer on top of it)
Midframe
Some of the AMOLED panel itself came off and was still stuck to the glass!
You can see how thin and fragile the AMOLED panel is on the Samsung Galaxy S series phones. Sure, it's thin, but is it worth it? The panel has to be supported by the frame and the glass to stay intact. The panel on the S4 has a slimmed down bezel and was made thinner again, so it's a lot easier to break the AMOLED on the S4 than it is on the S3.
Ugh, don't even get me started with the iPhone 5 screen. LCDs are more robust than AMOLEDS but still...so much LOCA...so much glass...
Sure, these glass panels can be had for about $10, but is it worth all the effort to end up with a screen full of dust and fingerprints, has a warped frame and will eventually come loose and fall off, or simply just to destroy the AMOLED panel then spending extra money on a whole display assembly? Reapplying the glass leaving no gaps for dust to get in requires adhesive that is machine-cut perfectly for your frame.
Edit: Even then, you still don't have any LOCA or the necessary facilities to fill that air gap. (Thanks to @KrzychuG !)
Do you have what it takes?
Sorry for such a long post. I'm spending my time, efforts and money so you don't have to. I will occasionally add to this thread when I get more screens to experiment with.
This is a good video on how these screens can be separated and replaced with a perfect bubble-free and dust-free finish:
Most of the time its a better idea to just buy an entire replacement. I've replaced glass on nexus 7's and Galaxy Note2's a few times. it's not fun to replace glass or lamination, and it's just a whole lot easier to purchase a "parts" phone with a working display from ebay and swap out boards. Glass is one of my least favorite things to play with.

Awesome dude! thanks alot for the tutorial, but i dont think people have industrial size vacuums in their house, lol,
Thank you so much, this is very helpful!
Can I ask how you got the information? That would be very useful to do further research about other devices
Thanks again!
I will never, ever separate the glass and the screen. I know that it will break for sure. When I replace phone glass, I replace the entire front screen assembly which includes the glass, screen, and any frame to attach it into the phone. Even if it's just the glass that's broken and the LCD still works, still replace the entire front assembly.

I think the point is that unless you have all this stuff you shouldn't be even attempting to replace the glass.
i have tried this multiple times and all i can say is for anyone at home wihtout the professional equipment your not gonna get anywhere.. this isnt like and iPhone 3G/S where you take the screen off and seperate the LCD from the digitizer with a heatgun or hairdryer, ive tried all possible ways an failed every single time, either broken AMOLED or in some cases half the AMOLED comes off with the adheasive...
just save your money and buy the digitizer with the AMOLED attached..

Chuck it
I have replaced many screens, and in my experience, you're always best buying everything as readily assembled as possible. Out of 5 attempts at separating the S3 Glass from the AMOLED panel, I have managed it twice without breaking the AMOLED, and that involves also keeping the digitser intact as well, which is between the outer glass and the AMOLED.
Back when I was doing this, you were looking at £175+ for the complete assembly, so to some people, £20 at a risk was worth it if I could manage it. Now though they're cheap enough to replace the whole lot without the worry.
There is an app on Play Store called ifixit which gives pretty detailed step-by-step instructions for most DIY teardowns and fixes for phones, tablets, consoles and even some household applicances, and they have a website too. Unfortunately, it's only experience (and expense) that make you realise that just because they make it look doable, it doesn't mean everyone can do it easily. There are many, many pitfalls that you will only discover yourself when you take on these DIY repairs, to the point where I don't do them all that often anymore, just because it's too stressful and costly if it goes wrong. My first iPhone 4 (am I allowed to say that here? ) screen replacement took me 3 hours just because of how careful I was. Now I can do it in 20 minutes, just because of experience. But even then you can be plagued with problems for no apparent reason. If you don't handle stress well, my best advice is to leave it to the experts

It never feels like I'm very good when I see the screen go though. Just that sick feeling :/
Saying that as well, I gave the phones back to whoever they belonged to when they were done. There's nothing to say that a couple of weeks/months down the line they faced the problems of dust under the glass, touchscreen sensitivity reduced etc. They were just happy to get them back 'looking' perfect.
Never again

your right, quallity also plays a BIG part aswell, like you said never know what could happen, but better brands generally have better touch respones and just generally more smoothe, i knew someone who had just got the digitizer replaced by a phone repair shop, they couldnt use their phone in the wind thats how bad the replacement was..
EDIT: response**
thank you, says my sii p
you saved a sii today, i'm using my phone without screen protection so it gets scratches after long times and i said to myself that's ok, i will replace the gorilla glass. that would be open the phone replace it then close it and i will have a new sii p again but sounds it's not that easy.
Very interesting thread.
I must be lucky,as on several occasions with most phones I have owned (HTC Desire hd, HTC One X, HTC One,Nexus 5, Samsung Note 3) I have accidentally dropped my phone. I've never had a case on and have on some occasions been unlucky to have the phone land on the screen, it has happened indoors and outdoors, on concrete and tarmac, despite this I haven't ever broken the glass.

I wouldn't follow the advice to "Chuck it". We purchase these cracked glass assemblies as long as the touch screen and LCD still work fine. We can pay up to $100 PER screen, depending on the model. PM us for prices for bulk orders.
I very recently bought myself an used Galaxy S3 and to my great disappointment the glass has no scratches because it has been replaced. Now I got ****ty touchscreen response and already dust is gathering between the digitizer and the glass. I might try to sell it off and buy myself another one, this time checking very carefully that everything is in perfect working condition!
So much for thinking I had found a bargain for this fantastic phone (which, despite the problems, is a nice upgrade from my Galaxy Ace!)

Please discuss cracked screens

I have a z3 that had a cracked digitizer. The damn thing broke under my cheap tempered glass screen protector. I call bull**** Sony! I paid premium money for a less than stellar screen in my opinion. Anyhow, I'm thinking about replacing the screen but can't decide the wrought to go. I could get an oem pulled from a z3 but I have to ask if it's worth doing for another bull**** screen that will break on me again. I see lots of knockoff screens on eBay and though I've had bad luck not buying oem before I wonder if they might use a digitizer that's on par with the rest of the market. I've never had a cracked screen destroy all functionality of the touch screen. I can't believe Sony used a product like that on such a kick ass phone. Please share all your experiences with cracked screens and repairs. Not sure why I couldn't use silicone to reseal the phone. The speakers may be a bit of a problem but I've accomplished quite a bit with cell phone repair and I'm up to the challenge. Please help me and our community to replace our own screens and retrain the waterproof feature.
not broken after 1,5 years. Wife's screen also not broken after same time.
Mine also didn't broken, bought the phone while the phone start selling.
Maybe your smartphone using too overheat and let the glass cracked?
To remove the screen you will have start by removing the back glass and the bottom speaker set (at least for my D6643). You would have to be carefull in order to not damage the bottom speaker waterproof adhesive (it's hard to find a replacement), you also need to buy a a new back and front waterproof adhesive to hold the screen and the back glass. Between a stock screen pulled from another from phone (if not too expensive) and a chinese one ($24), I would choose the stock since you will not find a lcd with same quality. Keep in mind that your phone may not be waterproof anymore.

Does the digitizer break with the glass?

Hi all,
Prospective 6P owner here. I've a question for those of you that have broken the glass on your 6P.
Regrettably, I've ended up dropping and breaking the last two types of phones I've owned—OnePlus One followed by Moto X Pure. Even more regrettably, both of their displays were designed such that the digitizer breaks with the glass, so broken phone = no more touch input. I think may head my explode if I continue blundering my way around my phone with volume switch control and google now, so I am motivated to purchase a phone that still works when the glass is broken.
Does the 6P fit the bill?
Thanks—
No. When my glass cracked the display wouldn't even turn on. Might be different for others as it wasn't the smallest of impacts
It all depends on impact? Watch youtube drop test video of 6p against iphone, 6p gets smashed touchscreen still works, but it can go either way. I think its the same with all modern smartphones due to the way they are built. If you keep braking your screens just buy a case and tempered glass protector...
It depends on the degree & point of impact
I've dropped the phone several times and only had a cracked screen once. Everytime I dropped it there was a Tempered Glass on it and the Tempered Glass cracked.
The one time I cracked the screen, the phone fell down screen first while I was taking it out of my pocket. So about a 3.5ft drop. This time the point of impact was on the edge of the lower speaker grill. The phone fell on the road with a bit of gravel. I reckon it was a piece of gravel that had the direct impact on the screen. The touchscreen was working perfectly & I used it for a couple of days before I gave it for repairs.
In any case, the service center replaces the entire display panel, even if the screen is working properly.
I'd recommend investing in an insurance. In India, insurance costs INR 3,000 (approx $45) & the screen replacement costs INR 14,380 (approx $212).
All the best!
