[Xperia Z3 Compact Q&A, Help & Troubleshooting] xilw3r:
I have sent an email to GSMarena.com suggesting to test out the theory of the temperature difference causing cracks to appear. Other people could send similar emails to other big phone and tech websites to encourage to try and simulate the problem, maybe some will respond and this will get the coverage it needs and finally some action from the damned Sony.

I wrote the following:

Hello,

Concerning the many reports one can find all over the internet of various Sony Xperia phones cracking without being dropped or damaged by the user in any other way, I and a number of other people have come to a conclusion that this might be happening due to a sudden change in the environment temperature.

I decided to write to you in hopes that you would be willing to investigate this issue by conducting a test (Z1, Z2, Z3 or Z3 Compact would suffice for this test, but I would suggest Z3 or the Z3 Compact as they are the most relevant these days) :

1) try to raise the temperature of the phones by recording 4K video or using GPS/ gaming or any other activity hard on the processor

2) put the phone in a vastly different temperature environment, for example a freezer

3) Should the theory be correct, after a while the phone should develop a hairline crack on either side.

It seems that this issue is rather widespread, and I am hoping that your website will dedicate itself to inform the customers of such potential issues.

Best regards

[Xperia Z3 Compact Q&A, Help & Troubleshooting] Howlbeck:
Well, have the Z3c since end of November and I'm still happy, it bugs me that there is no root yet but I can live with it. This is a damn nice piece of tec at this size.

Being from Germany we are now close to sub zero temps and I'm out a lot with dogs, that's why I was looking for a "waterproof" phone first place. A S2 and S3 from Samsung i owned before died from simple heavy rain while walking, having nothing at hand to cover...

So far no problems with the glass, neither front nor back. It is slippery for sure, but I never noticed the Z3c getting hot. I don't play complex games on small screens, maybe that's why ?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Tim.C:
Well, I took mine in to the nearest EE shop, who weren't overly surprised at my story, confirmed it was in mint condition (apart from the hairline crack) and that it was a known fault (at least to him!!)

It got sent off to the EE repair place, with a warning that they may say it's a chargeable repair, but hopefully not. I just rang them to chase it as it has been about 2 weeks, and they confirmed it is fixed and ready to be sent back to me, so I should have it back tomorrow or the day after.

I've really missed the phone - excellent in all but 2 ways.

1) cracking screen - believed to be due to 'twist tension' applied in manufacture to make it waterproof

2) stupid cover over charging socket to make it waterproof, and no 'standard' wireless charging, or Sony magnetic adapter provided

Basically, I think it's the waterproof bit that is all the trouble, and although a good bonus, I didn't buy it just for that.

At least I'll be able to play Bloons TD5 again soon ;)

Got my phone back after a week, anyone care to guess which is before and after the "repair"...

... so it came back from Sony repair with the word "Screening" in the repair notes which as far as I can tell from means "A few extra scratches for your inconvenience, regards sony".

Back to the retailer I think. :good:

Just received the quote last night, £108.

however I'm contesting the charge as mine shattered without dropping

Really think this phone is a piece of crap as is Sony's service

My Nexus 4 been dropped few occasions still going strong after 2 years

Happy New Year

Nothing like the new experience of having a phone self crack overnight!

Steps to reproduce:

1. Use the phone normally, (baby it, if possible, like I did).

2. Put it on the charger bedside at night before you go to sleep, like you normally would.

3. Go to sleep.

4. Wake up to your new, inexplicably cracked back.

Make sure you don't drop the phone or be rough with it, as the crack will not look so nice.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] degraaff:
A small corner crack like that has more likely happened from an impact.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Bernardos70:
I beg to differ, there was no impact whatsoever. The frame is intact, the phone was fine last night, and not fine tonight. You gotta wonder what tolerances Sony is working with. I think most reasonable people know not to be rough with their phones, but they also trust that they don't have to handle it with silk gloves at all times. I nearly do, and I never dropped/caused any impact to this phone. It lives on my work desk, on top of a leather box, on my nightstand, or in my front pocket, by itself.

When I said it happened overnight, I didn't make that up. I have very little stake in this, and no reason to lie about it, as I was just trying out Sony for one upgrade cycle, and I have T-mobile's Jump program. With that said, it is disappointing, but no biggie as I will in all likelihood go back to HTC when the Hima comes out.

TL;DR: there was no impact , don't mind it much, HTC m9 soon.

Crackiddy cracked

My phone was laying on the table, I was using it for browsing and suddenly I heard a *crack* sound. I was looking at it, because it was a weird thing and then I found a horizontal crack line on the back glass. I had an iPhone for 4 years, and you know, its also covered with glass and it felt down several times but the glass never damaged. I am very disappointed with this phone...
[Xperia Z3 Compact Q&A, Help & Troubleshooting] qnord:
First the front and now the rear!!!

I got the Ringke Fusion case and Nillkin H+ protector for front glass on my Red Z3 compact.

Within 2 weeks of using the front glass cracked in the middle across the length while carrying in jacket. The case and the Nillkin glass didnt even have scratch yet. The top half stopped responding to touch altogether. Sony support was prompt but took 2 week over Christmas to fix and return it but lost the Nillkin protector - luckily had ordered 2 in beginning.

But today the rear glass cracked in half - just below the NFC symbol. Its not a big deal and sending for repair is a hassle so will be using it like this.

Had an Xperia T before which took amazing amount of falls n beating and is still running well..so in comparison the Z3 Compact is big let down.. the size, speed and battery are amazing though.

This is bothering me. My first Xperia and this issue is making me want to trade it to a plastic Samsung again. =(
[Xperia Z3 Compact Q&A, Help & Troubleshooting] wayne_sk:
Don't do it. Just because reading this topic, it won't crack by itself. I traded mine for a 5S, and I kinda regret it. Miss those Android features, even thou the ecosystem is much better and camera performs better too, especially in terms of exposure. I don't mind the colors, those can be ajdusted, but correct exposure is very important for me. Z3C is a fine phone and you may get along with it. There are reports which confirm handling the cracks under warranty, so you have little to worry about.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] stinkypete:
Wayne, clearly the phone Is defective and Sony are not always repairing. That's why BBC Watchdog did a whole article about the fault.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] windsurftom:
My Xperia z3c has just had the rear glass crack spontaneously. A horizontal crack just above the Xperia writing on the back. Had been at work, put phone in front pocket, left and drove home, I had a screen protector on but no case. 100% certain there wasn't an impact. It has been hot outside - mid 30s and about 20 in work.

I have had the phone for 2 months and was very happy, recommending it to others. I have had iPhone 4 for 4 years and it wasnt taken care of as well and never got a crack.

Anyone who can defend the x3c construction is a wally, it does not appear fit for purpose (day to day phone use). Although it is a great piece of tech, because of the fragility I won't be buying a Sony again.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] kopiarz:
I've bought my Z3C 7 Days ago and today back glass broke by itself no pressure at all. Phone was in my front shirt pocket whole day there was no way I've hit anything... I'm really dissapointed couse I love design of Z3C
[Xperia Z3 Compact Q&A, Help & Troubleshooting] tahvero:
I would love to buy this phone but I'm afraid after reading all these threads of glass cracking. I'm moving abroad for a few months so dealing with repair/warranty would be impossible.

Why can't there be more (decent) compact phones available?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] stinkypete:
Tahvero Why don't you hang back for a few weeks, see what Z4 series is like. Personally I won't buy Sony again out of principal and I didn't think the Z3c was much better than the Nexus 4. Ideally I would like the Nexus 6 in the size of the Z3C
[Xperia Z3 Compact Q&A, Help & Troubleshooting] tahvero:
There are rumors about sony selling it's mobile division so will there even be Z4?

I agree with you, compact nexus 6 would be perfect.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] stinkypete:
I heard the rumours, however my guess would be the z4's are so far down the development chain that it would be bad economics to pull. IMHO
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Diio:
cracked mine

Well now my z3 compact did crack itself .

a small crack down in the left corner. from the corner to the camera button ( didnt see it at first)

Happend while i had it in my front pocket.

[Xperia Z3 Compact Q&A, Help & Troubleshooting] Tracy1988:
Because of politic in work place and greed and because there's so many dumb people in this world. Big companies like Sony has poured millions into R&D and have had years to get it right but none come up with a proper device. Yet their craps are still selling like hot cakes.

I used to buy only brand name products, from electronic to clothing but now I realized I've been a fool. Sony alone had fooled me with 3 phones in the last 2 years. No more Sony craps from now on.

I don't know a lot of things but there's one thing I'm certain of about the Z3C - its display is worse than crap: cheap glass, no coatings, touch electronic grids visible in direct light, deltaE is way off and sharpness is the worst I've seen. I bet my life on it that if you take the Z3C (or any other Sony crappy phones) to a lab to have professionals test the display, the result would be the worst of anything with the same ppi on the market right now, including the aftermarket's. I wish Sony just go to hell that's how bad it is.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Calvat:
Wow, I have to say thanks to you guys for making this thread. I've had an Xperia Z (C6603) for years now and the only crack that appeared is when I dropped it (first ever) on concrete, hit the corner and now it's rendered useless.

Looking for a new phone this seemed great, since 5" phones are kind of big for my hand.

But after seeing this thread, the reports on this are rather stunning and not exactly something I'd like to take a risk on. I seemed to have been lucky my Xperia Z didn't crack if it's been frequent through the entire Z series.;

I know that I run the risk with every phone but you can't deny these reports are more frequent than most - and not just 'I dropped it from a small height, what weak glass!', but literally "It was in my pocket and broke"? That's... well, that's not exactly ease of mind. There's already paranoia about dropping it as it is, none the less 'it exists therefore it may crack' lol
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Sadman Khan:
Yeah but there are also people who dropped it 4-5 times (thrice face first and once on the back) and yet there was no crack. Every phone will get negative reviews.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Calvat:
Yeah but there's also that survey floating around here which basically says 25% of people will get cracks.

With Sony's "no physical damage covered" and "quick to blame the user", I'm not exactly confident about purchasing a phone that could be rendered useless, or cost me 200$ because I bumped my hand against my pocket when I was carrying groceries.

Plus I'd intend to boot unlock so that definitely voids warranty, as if Sony cared in the first place.

I do see a lot of people admitting to drop it, which of course it'll most likely break. But I'm also seeing equally as many saying they just had it in their pocket and it broke for reasons unknown.

I know there'll be negative naysayers, and also people whose phones seemed to have been built by Vulcan, but it seems I'm not the only one who is being scared off by all this talk about the high rate of cracking. I've read a fair few posts now how people aren't buying the Z3/Compact because of knowing this.

This is just compiling up to be one big scare tactic for anyone who looks into phones to buy - and a scare tactic that's working.

My bigger question would be, why hasn't Sony done any form of recall on it? But... I've only known one company to do a recall on their phones and that's Apple.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Dsteppa:
Because it's in someone's pocket doesn't mean that nothing can't hit it and thus breaking it. Having it in a pocket could also increase the pressure on the phone.

But I also came from the Xperia Z and I agree that the z3c is more vulnerable.

[Xperia Z3 Compact Q&A, Help & Troubleshooting] Calvat:
I know, but that was just my personal take on it. People saying it slides off their tables or they drop it... I'm too careful for that. But I have hit my hand on my phone in my pocket when carrying groceries, you don't exactly punch your thigh now lol.

Some people just jogging and it cracks... I don't even.

I'm starting to think I'll yolo buy it though because I'm at a cross road compared to other phones. If I crack it, then I blame myself. If the phone just cracks, I guess there's nothing to do but sell it off and buy something else.

Everything is just too seriously big or there's some huge flaw to them, like battery life. This is great... but its durability is a feather...!

Why do you do this sony whyyyyyyyyyyyy.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] jerverg:
Dropped mine 3 times pocket height on tiles, no crack. Not even a dent.

My friend dropped his ear height on concrete, no crack, only small dent on the lower part of the phone.

And I dont go in this forum ranting about why my phone does not crack.

If there are 5 people who have cracked screens odds are all of them will go ranting somewhere, but all the other 100 who have no cracked screens won't.

Get the point?

Buy the phone you love, don't put a case and enjoy.

Just my 2 cents.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Sadman Khan:
Well i knew about these issues before i got mine but i decided to make the jump. I'm glad i did. It's all luck my friend
[Xperia Z3 Compact Q&A, Help & Troubleshooting] clouds5:
I can only agree. I bought the z3 day one and I've been anywhere from sea (30°) to mountain tops (-20°) dropped it a few times.. my friend pushed it off a bar just a few days ago. He flew off it with force. Nothing.

Those z3c that crack by themselves have some kind of manufacturer issue, I'm sure about that. Don't Worry about it and buy it, it's without a doubt the best phone in its category.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] AM Radio:
i've not dropped the phone (hopefully never!), but i have sort of accidentally bumped it quite hard against a chair or wall. tempered glass + fitBag, no damage. unless it's on my desk, it's almost always in a fitBag, even when in my gym pants or jacket pocket.

phone seems to hold up well under occasional heat stress. for example, earlier this week, came in from the cold, made a video call on Hangouts, mirrored the feed to my living room TV via Chromecast. call lasted 15 minutes. phone got pretty darn HOT -- much hotter than i've ever felt it. (also, gotta say that Video Hangouts via Chromecast screen mirroring = impressively smooth.)

but it's been months now, and no damage, no cracks.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Raptor270:
I'm very glad mine is still fine, even after i dropped it because i was drunk and tried to call someone :fingers-crossed:
[Xperia Z3 Compact Q&A, Help & Troubleshooting] stinkypete:
Yeah I think this is definitely down to a number of units that have had issue during the manufacturing process. My boss biggest gripe is that Sony are refusing to acknowledge this and in my case not willing to repair
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Zwulf:
Dropped my Z3C two times from about 30 cm and it's fine, no crack, nothing.

There won't be a device where every produced batch is perfect. I worked in a company that produces wafers (base for microchips) for Qualcomm, AMD, Samsung,... Sometimes there are batches that seem to be fine, but when used break easily even if tests were made. E.g.: I must not go into details too much (contract...); if some polishing chemicals fail, the production has to be stopped. Not to lose too much money those wafers can be polished again, get slightly thinner but work though. It might be that these are wafers of inferior quality, whose chips will work a while but break earlier than others. The company buying those chips doesn't even know about that (!). I know this is not glass but it can show as an example why some devices break soon while others don't. It's the same with glass, not only chips. That can happen with every manufacturer. Bad luck for those getting such a device.

Btw many manufacturers often use the same chips or other parts of the device, including type of glass (see GorillaGlass), so it's useless to blame just one company. Funny: iPhone also uses Samsung chips... ;) Many companies nowadays are fabless, that means that others produce the chips for the companies. Those "third-party" fabs are often those to blame, trying to produce masses in a given time - it doesn't always have to be the fault of the company selling the brand you buy. If the fab doesn't get it in time they have to pay for that (to the brand) so that they produce faster with less quality assurance, just because they made promises they couldn't keep.

It's not that black and white as many people think and it's not always the obvious one to blame.

The only thing that really pi**es me off on Sony is their politics. Deleted TA Partition and loss of main features (camera and sound quality) on root while stating to be developer friendly. What a nice joke... NOT.

Just my two cents. ;)
[Xperia Z3 Compact Q&A, Help & Troubleshooting] stinkypete:
Agreed, thing is this is been happening to Sony phones since the Z series launched
[Xperia Z3 Compact Q&A, Help & Troubleshooting] vikramkhalsa:
This.

Too scared after all the negative reviews, and don't want to deal with Sony's warranty/repair service - the experiences don't sound positive.

I wish there were some other good options.. (galaxy alpha?)
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Dsteppa:
Well... I guess....

The negative reviews will always stand out. Looking at the previous people that wrote above you on this topic the problems seem to have resolved themselves mostly and the problem (most likely) were due to manufacturing errors. It's been the same thing with the Xperia Z that I bought back then.

Just happened to me :crying: woke up and the phones had a crack all the way over the backside.

I'm abroad for a while but I'll make sure to get it replaced once I'm back
[Xperia Z3 Compact Q&A, Help & Troubleshooting] vikramkhalsa:
I don't see how they resolved themselves? You mean like people got them replaced? I dunno, all the official reviews of the phone are so good but the customers experiencing the spontaneous cracking seems to be a lot. I can think it won't happen to me but it seems like thats what happened to most people. No ones really complaining about the phone right, just that manufacturing defect or whatever. I haven't seen anything that makes me confident it won't happen on newer manufactured ones.. and how do I know if I'll recieve a defective one or not? And will sony make me pay for the repair? any guarantees? also Not too keen on waiting 2 weeks without a phone. Motorola has a nice program where they send you the replacement in advance.

I really do want this phone but it just doesn't seem like a smart idea anymore :(
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Dsteppa:
It's just like software.

For example v.1.0 of some app or software is being brought out (Z3C that was brought out back in September = v.10) many complaints/cracks so Sony does some adjustments and brings out v1.1 of the phone, with tweaks that must make sure that the phone doesn't crack that easy anymore.

The complaints are also less compared to when it just came out.

Reviews? What are reviews worth in this case? Most reviewers only used the phone for max 7 hours and did a review so maybe that's one of the reason that they didn't encounter those problems. Or they were just paid by Sony.

Paying for repairs? Well I guess it depends what happened to your phone. If you had a spontaneous crack then chances are quite big that they will repair it for free. But ofc you'll be without a phone.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] vikramkhalsa:
Fair enough. But is there any proof or indication that they did make that adjustment and fix it in later versions? I haven't seen any.. if you have something, please do share! From what I saw in these types of threads, it didn't seem like it was related to a specific build or version.

Exactly, I'm saying the reviews are useless and that why I had to look at these specific user instances. Do you own one? If so, how is it holding up? Is it one of the "newer" models?
