Also here the simple laws of physics apply: the bigger the screen, more surface = the more fragile your glass will be for breaking. The same story went with the s3 as I have never broke the screen. It aint that fragile you just need to be careful how you handle with the phone in pocket
[Galaxy S 4 Q&A, Help & Troubleshooting] bgstcola:
It seems like there are two kinds of ppl in this thread. Those who say that the s4 is very weak and those who say that it isn't weak and don't believe that the screen could break without abuse.

Isn't it possible that the amoled can break due to small imperfections? So that most s4 are no weaker than other phones with the same thickness and screen size, and a few are very weak?
[Galaxy S 4 Q&A, Help & Troubleshooting] Xetalx:
I bought the Otterbox Commuter case. Was so worrid at first holding the phone. So thin slippy / fragile...
[Galaxy S 4 Q&A, Help & Troubleshooting] Euthye:
Yup, it might be a good idea for the folk with anomalous breaks to give the info on the fone so we can see if it's a batch or factory or whatever with the weakness in the amoled, I'm getting the Spigen slim armor view because of this thread though I would have got a flip case anyway.

sounds like few people got defected units , thats it. it would be nice if everybody states manufactur date ,model and carier so we can compare results to se if some bad batch was the problem.
[Galaxy S 4 Q&A, Help & Troubleshooting] jamieridler:
Hmm mine has just cracked too now. A minor crack, hard to see but its there, at the bottom of the screen. This despite using a leather full front flip cover and never putting anything on top of the phone when on the table or in the same pocket as the phone.

Never had this happen with any other phone in my life, especially not after only a few weeks use.

Not good...

Samsung hasn't sold 23 million s4s. And the one hit 5 million in may.
[Galaxy S 4 Q&A, Help & Troubleshooting] noideaforusername:
23 million is probably really incorrect, but 5 million? You believe to an anonymous executive at HTC? :silly:
[Galaxy S 4 Q&A, Help & Troubleshooting] snxxxxx:
Wow, what happen in this thread?

I move to galaxys4 from the iphone 5, and i was a bad person for my personal phone. Im moved from i5 because i really tired to see the scratch on that. So i think plastic phone is better for me.

I use skinny jeans, and i always put my phone on my bed every night. Sometimes i found my phone under my body when i woke up. But nothing happened. My s4 is fully naked, i dont even use screen protector on it. Its preety fine since i dont even see little scratch on it.

But what im affraid now, my girlfriend just moving from her iphone too, and she had dropped her iphone many times, at least she's got 3 big dent on her iphone before it sold. Im worried she doing the same for her new s4.

Im just curious is it real? i hope mine and my girlfriend phone never had this problems. Really disapointed with samsung quality control. I'm just thinking to sell my phone and take the htc one. But too much love for the camera and screen from this phone!
[Galaxy S 4 Q&A, Help & Troubleshooting] fernando sor:
It's all speculation really. I'm not seeing any hard data on either phone
[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
There's semi-hard data based on how many are produced/shipped. Samsung shipped 10MM (taken at their word) in the first 30 days. Analysts are projecting an average of 6.7MM a month. So for April, May, June that's 23.3MM. Analysts have also been tracking the One's production so they could keep their HTC revenue projections updated.

According to brokerage firm J.P. Morgan, the production problems that delayed the launch of the flagship HTC One have dissipated over the last two weeks and shortages should end next month (May). Production of the phone should rise from just

300,000 units in March

to

1.2 million this month (April)

and

2 million next month (May)

. This ramp up in production could increase HTC's revenues by 50% in the next quarterly report.

HTC had originally expected to ship about 4 million units of the HTC One last month (March)

, but lost 80% of that number due to problems with components for the camera. Instead of a global launch last month, the carrier limited its release to the U.K., Germany and Taiwan. In the U.S., Sprint and AT&T are expected to launch the phone on April 19th while a leaked planogram shows that T-Mobile will release the phone in select stores on April 24th.​

So 300K in March, 1.2MM in April, 2MM in May, and somewhere between 2MM and 4MM in June puts them at between 5.5MM and 7.5MM through June. HTC's own Q2 guidance which April, May, and June comprise has them down 28% from last year so those analyst's number jive with that.

Neither Samsung or HTC break out sales by device so analysts' estimates are based on polling component suppliers to see how many of certain items ship and by reverse-engineering reported sales when they publish their quarterly reports.

It's really not tantamount to the conversation. Actually, neither are 36 broken AMOLEDs or 47 cracked camera lenses. In isolation those numbers mean

absolutely

nothing. When tracking defects it's the percentage of incidents over the deployed base. We have no idea what the deployed base is either in general or here on XDA. We also don't have a complete picture of the number of incidents because XDA is just an atypical microcosm of the real world. Outside the incidents<>units percentage the only thing else that matters is whether the percentage is trending lower or higher over time. The only ones who know the real depth of the issues being discussed are HTC and Samsung. And neither is going to release that information in our life time. So whether you're an alarmist or optimist this entire conversation is pretty much useless statistically. It is fun though. ;)
[Galaxy S 4 Q&A, Help & Troubleshooting] fernando sor:
I think both issues are relevant though. My experience on xda is when you get this much traffic on an issues thread there is something to it. I'm always checking my camera lens now anyways.
[Galaxy S 4 Q&A, Help & Troubleshooting] msavic6:
Theres a guy who works in a best buy near me who is quite the tech geek. I asked him if he had heard about the screen spontaneously cracking and he said he did but he thinks its a factory defect.

He then pulled out a store demo S4 and began flexing and twisting it in his hand, he told me he has tryed this daily and it still hasnt cracked the AMOLED. He feels because of his test that all the S4's weren't built equally and some have a defect which leads them to be weaker. I guess its the luck of the draw.
[Galaxy S 4 Q&A, Help & Troubleshooting] Rayfucious:
Can i know what's the direction your s4 screen is facing when you guys put in your jeans pocket ? the screen is facing you or outside ?
[Galaxy S 4 Q&A, Help & Troubleshooting] tclocki:
Don't get me wrong... I just find it suspicious that new members are going straight to this topic. I smell propaganda actually as I also believe the fraction of people reporting cracked screens are infinitesimal compared to the actual volume of phones being sold everyday. :D
[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
That makes a lot of sense actually. It's probably either the AMOLED panel itself or the way it and GG3 are bonded to the frame. Perhaps the frame itself is slightly out of spec. GG3 is what it is and so far it seems to be holding up fairly well. If it’s the panel or assembly the good news is that those types of issues are usually caught fairly early. One out of "X" devices is pulled off the production line and tested pretty intensely to catch non-standard problems. And with the lowering of sales volume the assembly lines won't have to work as hard and tolerances can be tightened.

It's pretty normal in problem threads; especially odd problems. As we go back-and-forth in our discussions and quickly add pages to the thread it gets indexed by the search engines. So "HTC One cracked camera lens" and "Galaxy S4 cracked display" point people to XDA. There were a ton of first time posters in the forums for the three devices that had problems I mentioned above.
[Galaxy S 4 Q&A, Help & Troubleshooting] chalid:
Yes, this proves what I said a few pages back. Samsung (and any other manufacturer of a flagship device for the worldwide massmarket) will test their devices thoroughly before launching them. They would be insane not to - especially with a phone like the SGS4 which is part of one of the most important smartphone lines on the maket.

So the statement in the threadtitle is obviously wrong. The SGS4 is not "very weak". But there might have been something wrong with the threadstarters and maybe some others devices. A few pages back someone reported that their repaired (and sold) SGS4 cracked again after a few days. That seems to confirm this theory, because if all phones were that weak, there would be a lot more broken screens.

I might be wrong, but it seems to me, that most of the people reporting screen cracks where using some kind of casing.

I've been using the SGS4 for 6 weeks now, carrying it in my front pocket every day without any protection, and keeping it there even when I sit down (car, cinema, restaurant ...). No problems whatsoever :)
[Galaxy S 4 Q&A, Help & Troubleshooting] rtoh:
It should be covered under warranty since the outer glass did not break. My friend had a same situation with his Note 2 and it was changed without question ask.

On a side note, did something erected near the pocket that caused the inner crack? :rolleyes:
[Galaxy S 4 Q&A, Help & Troubleshooting] PantsDownJedi:
Don't care about the argument; pulled this from a few pages back and I recalled once wondering if the SGS2 (again, as a previous owner) would have been money better spent than the SGS4.

I had a chance to play with my old SGS2 a couple of days ago and holy crap am I way more satisfied with the SGS4. I put them side by side and everything from the screen size to screen resolution to display size to screen colour and then harder hitting hardware on top of it, I can't imagine wanting to go back to an SGS2 now. The only thing better about the SGS2 was that the volume and power buttons are really accessible whilst harder to get to on the SGS4 despite being in the same exact place, as a result of its size.

Seems like there's a lot of people's horse crap effecting each other. I decided that this horse crap post was appropriate since its a non ending crappy thread. I'm not going to apologise for an off topic post in a thread of futility so I feel pretty free to just post random reactions such as what reading something made me think of; its my right to type horse crap as well. Hell, I should blog in this thread.
[Galaxy S 4 Q&A, Help & Troubleshooting] Skander1998:
Can anyone please with a cracked AMOLED and an intact glass disassemble the phone and take pictures of the magnesium plate that is holding the AMOLED?

We can compare that to see how it matches with a normal non defect model.
[Galaxy S 4 Q&A, Help & Troubleshooting] SSTaLoN:
my screen was facing me when the amoled cracked.
[Galaxy S 4 Q&A, Help & Troubleshooting] Euthye:
AFAIK we don't have a magnesium plate ours is plastic.
[Galaxy S 4 Q&A, Help & Troubleshooting] Skander1998:
Nope, if that was the case the phone would be flimsy as hell - it has to have a magnesium plate, just like the s3.
[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
Neither have a magnesium plate.

http://www.ifixit.com/Teardown/Samsung+Galaxy+S4+Teardown/13947/1

The N2 does though. Item 3 below.
[Galaxy S 4 Q&A, Help & Troubleshooting] Skander1998:
The S3 does, it is covered by plastic from the back and some stuff , so you can't really see it without removing that, you can see it in Erica's video of burning the screen, everything melts except the magnesium plate.

The one on the S4 should be on the first image, number one (back side, probably hidden with plastic too).
[Galaxy S 4 Q&A, Help & Troubleshooting] Beefheart:
A nice long post there but, when all said and done, no phone should crack as a result of someone's normal behaviour whilst it being in their front trouser pocket. And if it does it's frankly not fit for purpose.

But saying that, I'd put a rigid cover on it of some sort. There are enough of them to choose from, and without spoiling the look of the device.
[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
I know "fit for purpose" is big in the UK. Where's the definition of "fit for purpose" as it comes to the durability of a device with components we all know can be damaged to varying degrees? Saying the SGS4 shouldn’t crack when other phones haven’t is totally subjective and each scenario is unique. Because the SGS4 doesn't do as well in trouser pockets as other phones doesn't mean it's "unfit," it just means its less durable being pocketed (subjected to stress). You can claim to a watch dog that the SGS4 shouldn't crack when it does but with no "standard" to measure it against and so many ways for any phone display to be cracked it's going to be awfully difficult proving it's not fit for purpose.
[Galaxy S 4 Q&A, Help & Troubleshooting] Beefheart:
It's really very simple, and the geographical location is a compete irrelevance as we're discussing what should be common sense here. The Galaxy S4 is a mobile device, and it should be possible to take certain things for granted as a result. So unless you're suggesting it be kept in a teflon box attached to a belt clip, having the display on a disproportionate amount of devices break under the everyday, standard duress other phones appear more than capable of dealing with (including previous generations of devices by Samsung themselves) is completely unacceptable.

I'll carry mine in a fanny pack than cuz holsters suck

-- Sent from my Palm Pre using Forums
[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
You're missing or ignoring the point I'm making. I fully agree the SGS4 with its thinner form factor, larger display, and smaller bezel is more susceptible to damage from stress than the SGS3. But why does that make it "unfit?" People here are expressing an expectation but there's a difference between that and a defined and measurable standard that the SGS4 is on the wrong side of. Samsung made no claims as to the durability of the SGS3 or SGS4 that could have mislead people which is what watchdogs go after. And "my SGS3 didn't crack" isn't a smoking gun against the SGS4 and wouldn't be taken seriously as there are a ton of variables that can cause any devices display to crack. So far there's been between 12 and 15 cracked screens reported. If there are tens of thousands in the next 90 days that's something that would get a watchdog's attention as that average would be notably higher than other phones. If the average stays in the 1-3% range, even if that's higher than the SGS3, it's going to be hard to claim "unfit." The increased likelihood of the display cracking may make the SGS4 less desirable but there's a big difference between that and unfit. The good news is people are aware now and can be careful or skip the SGS4 all together. Who knows? Maybe this is why Samsung's releasing the Active.
[Galaxy S 4 Q&A, Help & Troubleshooting] JihadSquad:
Just a question for those who have broken their phones like this: do you all have I9500s or are there some other models?
[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
Here are the tear downs of the SGS3 and SGS4. At least to me, there doesn't seem to be a noticeable difference in the design or construction. In fact the SGS3's plastic sub-frame is two pieces and the SGS4's is one which I imagine would be stronger in terms of preventing flex. Although the SGS4 has a larger battery cut out that’s much closer to the edges of the phone. I'm no engineer so don't know if that would affect rigidity. The front glass, display and plastic frame are fused in to a single assembly on both phones so unless those components in the SGS4 being notably thinner is a contributing factor to the cracking that too is the same. So looking at the tear downs there’s no “ah ha!”

From iFixit - The glass is fused to the display, and the display to the Galaxy S III's frame.

From iFixit - Unfortunately, the display and front glass are fused, with a layer of optical adhesive. The glass is then adhered to the plastic display frame, making a single assembly. Not a big surprise.
[Galaxy S 4 Q&A, Help & Troubleshooting] Beefheart:
I'm neither missing or ignoring your point. But perhaps the simple truth is we have different definitions of unfit after all in the same way people from the UK and US generally have very different definitions as to what justifies litigation. For me, a disproportionate amount of Galaxy S4 devices breaking in people's pockets with no misuse is a reasonable definition of the word given the purpose of the device. You clearly don't agree so perhaps we'd best move on.
[Galaxy S 4 Q&A, Help & Troubleshooting] Simply_Android:
the screen didnt break, it was fried by a electricity short in the motherboard, maybe you sweat in your pocket, i am a mobile technician and i have seen this before,

Not to be an ass, but not all jean pockets are equal. For instance, some jean pockets have a fat bastard behind it while others don't. Are these phones tested for fat bastard creases?

(On a more serious note, my phone is always in my pockets and go through the usual sitting / standing routine... no cracked screen. As a data point, I'm not a fat bastard though.)
[Galaxy S 4 Q&A, Help & Troubleshooting] Beefheart:
You think? I think it's quite clear from the descriptions (and photographs) in the various threads on this subject that the AMOLED panels have cracked as a result of pressure exerted on them from the phone flexing. I'm extremely sceptical about the shorting theory.
[Galaxy S 4 Q&A, Help & Troubleshooting] Simply_Android:
a short from behind the screen where there is little protection against hits/blows to the screen not like the front panel where there is gorilla glass,

what happens if you put a Glass cup into a oven, thats right it breaks from heat, and being under pressure and tension, im not trying to be a smart ass. but im just saying the obvious, that was in front of our eyes the whole time
[Galaxy S 4 Q&A, Help & Troubleshooting] Beefheart:
It's neither obvious or in front of my eyes given that my phone is fine. However, I don't agree with your assessment of how it has happened to the people who have suffered from this issue.

[Galaxy S 4 Q&A, Help & Troubleshooting] Hendrickson:
I have talked to Samsung support a few times now today. They will not repair it for free. They claim that broken screen means the phone must have been abused. Dropped or bent. Which I did not do. They don't know of plans to recall the phone or fix the screen breaking issue. According to them there is no issue.

I have to take the phone to an approved service center but its going to cost me about 200-250 euros to fix. This is pure BS.

I don't think I'm going to buy anymore Samsung phones again. I was a fan of there phones but it seems in order to make the phone thin they sacrificed the strength of the phone way too much. And have created a phone with a real weakness that can take even the stresses of a jeans pocket.

NO im not fat, I'm 182cm tall and 80kilos. And no I don't wear tight jeans. These where normal loose fit jeans.

Highly unimpressed with the weak S4. I will sell it on Ebay as Spares. At least someone can replace the screen and resell the phone its perfect apart from a broken Samolded. I will stick to the Optimus G Pro. It might not be as fast, but the 5.5" handles a jean pocket without any issues.

Here's what iFixit said...

The front panel assembly is the final piece to the puzzle. Unfortunately, the display and front glass are fused, with a layer of optical adhesive. The glass is then adhered to the plastic display frame, making a single assembly. Not a big surprise.​

[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
That's actually a pretty cool video. I didn't know what the "super" in Super AMOLED meant until watching it. And you're right. The SGS3 does have a magnesium sub-frame.

And it appears iFixit was wrong about the SGS4. Here's a different shot of the sub-frame. You can see the inside of the screw holes are metal. So what's "grey" appears to be magnesium.

Same thing happened to mine about a week ago. Phone was in front pocket screen facing leg, had an otterbox commuter case on it. Got in my car and drove maybe 10 miles and the amoled got a half inch crack top right corner. Phone has never been dropped, I don't wear skinny jeans and I'm thin about 5'11'' 165lbs or so. Phone is the US Verizon quad core model and I owned it just under a month. Still trying to get it repaired but might end up buying the parts and doing it myself. Tempted to sell on ebay if I have to pay for the fix. I've owned several smart phones and always carry them in that pocket in similar jeans screen facing in nothing else in the pocket. Interestingly my sister has the exact same setup but much tighter jeans and has dropped hers but hasn't had any problems so far. I've also intentionally stressed a display model at Best Buy pressing hard and twisting/bending the phone with no ill effect so maybe it really is some kind of defect or luck of the draw.
[Galaxy S 4 Q&A, Help & Troubleshooting] msavic6:
So far this is the most likely cause and its quite unfortunate for all the people affected.

All the people who I know that own an S4 havent experienced this issue and most of them carry the phone around naked. Flexing the store demos hasn't shown any cracking for me either.

Ive had mine since the first of June. I've dropped it three times ( I have 6 children under 12) I always carry my phone in my back pocket and so far not even a scratch. I could be lucky or maybe there are different places they are being produced?? Has anyone seen a pattern with the ones that crack?
