If you don't want to use a case, I'd suggest to get at least a front and rear tempered glass protector.

Not using a case is taking a big risk nonetheless, because the phone will fall at least once! As long as it falls on it's face or back with the screen protectors, you should be good.

Dropped my Z3C about 4 feet high from the ground. Still no cracks. Btw, both sides have glass screen protector on. :)
[Xperia Z3 Compact Q&A, Help & Troubleshooting] stinkypete:
Eespanol what's your point? This thread is about the glass spontaneously cracking. Not how clumsy you are
[Xperia Z3 Compact Q&A, Help & Troubleshooting] jerverg:
Been rocking mine naked since early January. Been with me on my travels on the beach, waterfalls, etc.

Dropped once but no cracks. Been soaking it in salt and fresh water alike no issues whatsoever. Apart from some dirt on the sides on the back beside the glass edges.

Everybody's been commenting on how pretty the phone is. The reason I bought a pretty phone in the first place.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] SlinkyMalinky:
Had mine since Sept, no cracks or scratches. Then a few weeks ago I pick it up and feel a big crack on the back.

It wasnt deep but you could feel it and suddenly it feels very weak. Oh and dont try Sony like I did as you'll

just pay them to repair it. They look at it, sorry I mean run extensive tests, then tell you it was your fault.

Before then I was like most people. Anyone with a cracked phone most likely caused it somehow by themselves.

There might be a theme in regards to the older batches of Z3C's having issues but either way its pot luck.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] ro_explorer:
The back is cheap and easy to replace; I would no be worried about it ... I'm more concerned about the front - that IS expensive :).

[Xperia Z3 Compact Q&A, Help & Troubleshooting] SlinkyMalinky:
Ha sorry about that but that Saygus phone looks great plus perfect specs too! The main thing I've loved about the Z3C is its decent battery.

If it had a bare bones install of Android it would be much better.

Oooh snap! Dropped the phone a couple of times before, not a scratch!

"Tossed" it on the super soft couch 10 centimeters, came back after a minute, huge diagonal crack on the back:(

I'm the living proof that it can happen, as I'm extremely skeptical to others claiming "I didn't do nothing":) But I didn't do nothing:)))
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Diio:
Got my Z3C back the other week from repair after i got a small crack and the touch stoped working.

Got it fixed on warranty witch is nice :)

I'm now more carful how the phone is placed in my pocket so it wont "bend" when i walk up stairs and so on.

sounds ridiculus to do this but dont want it to break again^^
[Xperia Z3 Compact Q&A, Help & Troubleshooting] eespanol:
My point is, mine doesn't crack no matter how many times I dropped my phone. :)
[Xperia Z3 Compact Q&A, Help & Troubleshooting] vikramkhalsa:
Yeah, I really want the z3c but I'm thinking "it won't happen to me" and thats probably not the safest way to go. I'm just losing patience because Saygus is being delayed and theres no clear shipping date. Probably better to wait for that, at least the Kevlar won't crack! lol

First post!

This is my first post and my first Sony phone! Coming from an LG Optimus G that also has double glass, I know how fragile this phone is, there's just no way around that.

Had it for 2 weeks, read a couple of the posts pointing out to how change in temps causes the crack. I realized how warm this phone gets especially when charging or under load.

Now, whenever I'm gaming or charging I open all the ports just to keep it from heating up and getting that dreadful auto-crack.

[Xperia Z3 Compact Q&A, Help & Troubleshooting] AM Radio:
some of the incidents really suck, granted. but don't let these reports dissuade you. i've had my phone for months. no cracks, no damage, nothing. slapped two tempered glass protectors on it, stuffed it in a FitBAG, and i don't worry about it.

side note, unrelated: man, i wonder how the new Sammy S6/S6 Edge are going to fare with all that glass ...
[Xperia Z3 Compact Q&A, Help & Troubleshooting] kineticRX8:
Bought mine October had casebase screen protector on it slippery thing slipped out my hand and landed face down on hard tiled floor...oh no I thought as I picked it up, the screen was screwed just coloured bars and what looked like a small crack across the bottom of the screen. The casebase didn't crack! the crack was underneath. Sent to Sony and have no phone, reports around if your lucky you wont pay if not you will pay anything up to £150. Sent 6 days ago just says device received no other updates which is pretty rubbish. Interestingly when I log onto my support page for a split second NON WARRANTY REPAIR flashes on screen and my normal support screen appears. Doesn't look good for me...I'm prepared to pay £30-£50 not half the price of the phone though. If you are thinking of buying this phone, and this is the first phone I've cracked and had screen completely unusable, I'd defo get insurance and a iron case with screen protector maybe put two screen protectors on and then put them all in a pillow. Probably still break...
[Xperia Z3 Compact Q&A, Help & Troubleshooting] DarkNate34:
These are just reports by users who had bad luck. Same thing was reported for other "Z" phones. I have had my Z1 since August, dropped many times, nothing "cracked". You could always buy the Device and GET INSURANCE which is not so expensive at all, at least not down here in India.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Calvat:
I was pretty concerned about this issue, but I went ahead and bought one anyway. One week now. If mine does the same thing, I'll definitely post.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] kineticRX8:
Well, well, well second post only to confirm the mother hubber is being posted and is in transit. I must of fell lucky or perhaps Sony are recognising after numerous complaints the glass aint up to it. Either way I'm rather chuffed at not forking out and may I say again this slipped out my hand and landed on the floor face down, any other phone would have been okay as I've dropped phones from higher and harder at the floor and they've survived, I just knew when this hit it wasnt gonna be a good ending. Now to look for a case but I doubt a case will help as my screen protector never did. Anyways apart from its glass the phone in general is a top device.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] kiliimanjaro:
I've had mine for about a month and have a tempered glass screen protector on it and never dropped it or any hard bangs etc but yesterday I had taken the phone out of my pocket and the side of the glass screen protector had cracked and glass fallen off. The actual device screen seems to be fine, but it's odd that the tempered glass screen protector randomly just cracked for no reason.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] :
My phone's fine, I dropped it from like 1,5m down on stone floor and it slipped quite a bit on the floor before I picked it up.. The phone survived just fine, there's absolutely no cracks, scratches etc and the plastic frame around the phone got no dents. The small black plastic thing that holds the glass lost some plastic paint thing, but it's so minor that it's not even noticeable :)

So to me, this phone is extremely rigid and no self-cracking glass either :)
[Xperia Z3 Compact Q&A, Help & Troubleshooting] beirutas:
Well you got lucky. That's all. My z3c develops a new crack after every drop even if it's just 40cm fall from the coffee table on to the carpet.

Never in my life did I have such a fragile device.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] :
To me that sounds like a fabrication issue, as my phone is extremely sturdy and does not crack after drops.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Schlubahaus:
Just to add my 2 cents: It has happened to me twice now. Have had the phone for about 3 months now and have sent it back a total of 3 times now, of which 2 because of broken glass plate (back).

First return was because the edge connectors/buttons stopped working: No charge, no screen on/off, no volume, nothing. Was fixed free on warranty.

Second return was broken glass plate on the back like many mention here. Happened while skiing. Though I have no case for the phone, it was in my pant pocket and I didn't fall. It was only about -5. Was fixed free on warranty.

Third return was again broken glass and I just got it back last week. Happened while in my pocket. The one moment it was whole, the next moment I felt in my pocket to take it out, it was cracked. Was again fixed on warranty.

I indeed find it interesting too that this keeps happening out of the blue. Especially since this is supposed to be the most "robust" phone I have ever had. Oh and yes I am planning on getting a tempered glass sticker for the back now :p

By the way: Has the OP been able to draw any conclusion on all the info gathered from the google form?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] geronimoid:

[Xperia Z3 Compact Q&A, Help & Troubleshooting] 2mal16:
I think also one has to always keep in mind whether the replacement phone one gets is from the same pool of failed production products.

There was a guy on amazon germany who got like (different) 7 phones send as replacement and every single one of them had issues.They also had different production weeks. So they probably just kept circling the bad/"repaired" ones back to him. Poor guy.

His problems were not related to spontaneous cracking, i just mentioned this to be aware that the problem sometimes may not lie in the phone itself but in your reseller you bought your phone from.

I used this phone the whole winter (Temps up to around -10) have dropped it a few times and no issues whatsoever. now about almost 7 months with this phone. 2014 Week 36 production.

Tempered front screen protector+bugdroid case(since 1 month, before just some cheap nonprotective case to prevent scratches). I dont see any reason why you should NOT get a tempered screen protector. Regardless which phone you run they can all shatter. Even if they dont for 100 times at number 101 when it does you will still regret not having invested +10 euro for a 400 euro phone...

At the beginning i was checking my phone regularly in fear something might spontaneously crack now i know it has to be some manufacturing/quality control problem and have stopped worrying.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] DarkNate34:
Yeah, I use a leather case after dropping it. I tested the cold temperature thingy by putting it on the freezer for 6 minutes, temperature dropped to 5.0°c on the sensor, nothing cracked, but I wouldn't risk going below that nor try it again. My Z1 however can get really cold and hot and still work just fine.

I'm really sure, why people have this self-cracking glass issue.

FIRST POST

I bought this phone 3 days ago and its on the way in post and only discovered there are issues yesterday. I live in Ireland and cause cant buy sim free device in a shop (and my network provider offered only black:P) I decided to get one in Poland - proper shop and all.

Already found out SONY Poland says its always your fault and there are no screen issues abroad they know of (!!)

Already found out everybody seems to believe its a hoax - till it happens to them ;)

Already found out I should not have bought it if I want to use it as a phone - carry in my pocket or my bag, leave it in a car, charge it, play games on it, hold it, use it, touch it - better not. It may be water resistant but not waterproof so never ever use it when its raining, dont bring it near water ever. Dont buy it if you live anywhere its cold! Never take it outside. Seriously just let it sit nicely on the table...and it still may not help help ;)

I was so so excited now im terrified! Do you think that opening the flaps would actually help with the overheating/cracking issue?

I've been playing games / watching stuff to a point where the phone heats up in my hand to some minor uncomfortable levels, and going back and forth between 9C and 30C and my phone still shows no sign of glass injuries in anyway.

The theory that temperature change plays into it makes total sense to me, one milliliter of something missing in the factory could warrant instability during temperature change, or just the glass in general. Mine shows no issues with temperatures it seems.

I think it has the worst glass ever made, after one week the back is full of scratches, the front has 2 already, one about 1 inch. Mu xperia z is 2 years old and is almost like new without a case or anything. Hope sony mobile division will be sold, expensive devices and the cheapest glass ever.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] DarkNate34:
You should have bought some Screen Guard out tempered glass or a case/flip cover. The old Xperia Z has an anti-shatter film on top of the glass.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] smardu:
Which were removed by me after one month : )

Today i did something else, i took a pen and tried to scratch both sides, the fron glass is like a plastic, the back one a little bit strong, the conclusion, i have 2 more scratches now on both sides. Z3C glass is plastic compared with Z glass.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] DarkNate34:
Stop being ridiculous. It's NOT plastic, unless you have proof. I use a Screen guard on all my phones, never had any issues. Want a strong scratch resistant glass? Go for mineral glass (which in case you didn't know doesn't exist for mobile phones).
[Xperia Z3 Compact Q&A, Help & Troubleshooting] smardu:
: )

Try it by your self, its not plastic, but it is way less resistant than a china glass protector.

0.33mm + 0.33mm means A LOT for a 500E phone, dont you think?
[Xperia Z3 Compact Q&A, Help & Troubleshooting] Calvat:
The bottom mid? That's where it was heating up for me. Between the middle of 'Sony' and 'Xperia'

I also did another similar test, I'd play games until it heated to the same uncomfortable levels and then put it on my aluminum mousepad when it was 8C (Not sure the temperature of the mouse pad itself though, felt colder). It went cold pretty darn quickly but still no change.

Saying that, I have a tempered glass protector on the back of my phone so I'm wondering if that made it not break.

Done all I can to make my phone crack that's reasonable (Been using it regularly every day since I got it + The tests) and no signs. I feel like I let everyone down failing to see if the temperature shifts caused cracks but it's not doing it for me.

To be fair I think in this day and age you're a bit of a silly person to not be buying a screen protector the moment you take your phone out of the box.

There's some definite changes in the design of the phone's materials though:

http://www.xperiablog.net/2013/02/20/does-the-xperia-z-use-both-dragontrail-and-gorilla-glass/

http://talk.sonymobile.com/t5/Xperi...-of-glass-is-on-Xperia-Z3-Compact/td-p/838791

So... it's a gamble which material you get for your screen?

I can't find the post, but someone gave a summary of "One type scratches easier but more shatter proof, one scratches less but less shatter proof" but I can't remember which is which.

Perhaps the cases of cracking is the people who are getting the easily-cracked one?

Otherwise that last link is quite a read though.

[Xperia Z3 Compact Q&A, Help & Troubleshooting] newbie2006:
UGH, owned phone for 2 months

Crack (hairline) over bottom right of phone. It was not dropped and its kept in a wallet case.

I did notice that I was in a room that had a very cold AC and then i noticed by afternoon it had this hairline crack.

I was hoping that when i got this phone, and reading this very forum page about the cracks, that i would not get it - well i do now. lol

So anyhow I bought it NEW from EBAY - and i am wondering if anyone attempted the repair on their own?

I see its http://www.amazon.com/display-Scree...81&sr=8-2&keywords=sony+xperia+z3+compact+lcd

but wondering how difficult is it - I repaired a few over the years the HTC ONE X and iphones but wonder about this - as i am sure I will lose the ip57 specs.

So, I got a crack on the back panel, and it kinda wasnt a crack, more like a scratch but it wasnt on the surface, but under the glass cover. but anyway , crack is a crack but it dint bother me because it didn´t give me any glass shards cuz it was under the cover. Next day I put my phone on charge, and I went to get some morning cofe, when I later came back (5-10min) and picked up my phone for messages, the whole back panel had shattered. I got few glass shards on my hand also. I guess its not waterproof anymore :( , I really liked this phone.
[Xperia Z3 Compact Q&A, Help & Troubleshooting] :
I think my device is quite safe against self-cracks as I've dropped it a few times by accident already, from a variety of heights and there's no visible damage almost so I think this is a well built phone. Last time I dropped it was yesterday down from the stairs, and it survived with no damage. However, I'm certain that all the phones that cracks when dropped from low heights and / or cracks by itself, as that's not normal.
