[Xperia Z2 General] djgodlike:
14W17 Dutch Vodafone Branded.

Bought: 14/07/14.

Recorded max 3:30min 4k on Samsung Pro 64GB SD. Started with 39degrees Celcius Battery temp, ended with 48 C..

Camera gets also too hot in Manual mode when shooting many pictures (test done in 26degrees France)

Already did remove some camera apps.

Ai mode feels a bit more stable and gets less hot...[emoji6]

14W17. Greek cosmote device.

Mine is black one.

It got hot and stopped recording 4k at 2:32. I use a 64gb class 10 Kingston.

A bit disappointed ?

Anyone from week 28 with overheating (camera shutdown error)?
[Xperia Z2 General] 2015Ducatimulti:
I just got got mine yesterday from amazon and it 14w30 and it does not have the skewed gaps on the front screen and take a lot better pics then the one i bought way back May 12th I`m happy as a clam:D
[Xperia Z2 General] tel033:
Any camera shutdown in direct sunlight or hot temperature? Did you bought it from mobile front or another seller?
[Xperia Z2 General] 2015Ducatimulti:
no problem with direct sun light, I was out yesterday taking great pics with it when we were out Kayaking on a lake, and I have not noticed it getting hot yet. and it was directly bought from amazon and was fulfilled by amazon because I paid 8.99 for next day Saturday shipping and it was purple one i bought.:good:

When did you bought it? Do you live in a hot Country? Around 30C ambient temperature?
[Xperia Z2 General] AlexTek:
Hello,

I bought my Z2 here in Portugal unlocked (14w30), 1 week ago, for my little experience and Service Tests, all looks good, but i already ask in xperia care if its normal to take almost 10 seconds to start (since pressing the button untill vibrate) but dont have an oficial answer, just an user that says that the phone takes 5 seconds to start too, can anyone give me a feedback about these. (My firmware is '402')
[Xperia Z2 General] d3vaS:
14W26 - Unit for CE1

Echo and cracking noise in ear speaker during call. :( (during music playing with stereo effect sounds good)

4K recording without overheating and build quality looks really good.
[Xperia Z2 General] Jhon998:
How long it lasts recording 4K?
[Xperia Z2 General] d3vaS:
"only" 11+ minutes, i'll try longer one for test.
[Xperia Z2 General] Jhon998:
Undervolted cpu right?
[Xperia Z2 General] d3vaS:
13:40 and after this unit say - memory is full :D (5,27GB this video file)

But still without overheating.

Build nummer:

17.1.2.A.0.314

All settings are default.
[Xperia Z2 General] tel033:
Are you in a hot ambient temperature?
[Xperia Z2 General] d3vaS:
Not too much, normal room temperature 20 - 22 celsia. Yes, probably in higher ambient temperature this problem will be show.

Wow, first of all, didn't know that we can check the manufactured date on the "black thing".

Mine was 14W18.

No gap at anywhere even though i dropped it few times before.

No issues with 4K recording and calls.

Pretty fine so far.

Heating / gaps / call sound / (Ability to) recording 4K more than 10 minutes / non-centred camera lens.

You're unlucky.

Mine is 14W19 and everything is fine except bottom and top gaps. Stuck dust and sand...

Thinking of switching to higher week.

14w21 :) all good, running perfectly.
[Xperia Z2 General] DeathMetalDiamond:
14W27 here, so possibly manufactured between June 30 and July 6 - the week of my birthday this year. :)

Running good here with the last software version (.314). Build quality looks excellent but there are already a few very minor scratches in the back glass. Front one is still factory-polished. :)
[Xperia Z2 General] griffin_1:
So, it seems like those made around week30 have the issues fixed right? Anyone with the more recent ones can confirm if they still show overheating issues, gap problems, glass cracking(i think this came from excessive heating)?

z2 14w31

Hello , i'm from Poland . I have z2 of the week (14w31) phone heats up to 45 degrees while playing for about 15 minutes. break from one side of the cover of the SIM / USB and break the bottom left of the screen
[Xperia Z2 General] griffin_1:
So the glass broke itself right? It might be due to temperature changes,but still not ok. I thought the ones from week30 and after would have that fix. The temperature, since it was a game for 15minutes is not that bad. I mean, it shouldnt be that high but even the s5 , m8 and g3 heat up a bit (the s5 seems to be more using 4k), so i guess is somewhat aceptable comparing to the others
[Xperia Z2 General] cenasecoisas:
I wouldn't call it acceptable a flaship device to crack itself like that
[Xperia Z2 General] griffin_1:
I meant the higher temperature when playing a game for 15min. The self cracking glass inst aceptable at all. Also from what i read, or at least the reports i have read, sony isnt acepting them under warranty and they most likely know the issue by now.

Its a shame, because its a awesome phone if not for those issues.
[Xperia Z2 General] cenasecoisas:
It's indeed a shame. I really was tempted to buy a z2 but I think it's a bit risky to spend around 500€/600$ and get a faulty device =|

Sony should cover under warranty those devices since it's entirely their fault and not users fault
[Xperia Z2 General] Mahdian57:
14W21

Uncentered Camera! and Flash Diode!

Top Front and Rear Gap!

Damn it!
[Xperia Z2 General] acb123:
14W18

Here is my list so far (I can take pictures as proof if anyone wants so)

A big gap in the bottom left of the phone

An off-center camera

Dust under camera lens

Gap in the upper right chassis

Left SIM not closed fully

Overheating with normal use

Just FML. I'm still looking for dead pixels. And thanks to gaps and the left SIM door not closed fully, I had to send it back to Service center 2 times because mine couldn't even stand for a water splash :mad:
[Xperia Z2 General] CarlitosMendezR:
Can somebody please upload the picture of the plastic thing where the date is printed, because just got my new Z2 it week 31 2014 but it has some Chinese letters, I don't think it should have Chinese letters...... Thanks in advance

[Xperia Z2 General] griffin_1:
Not even overheating? Like, really excessive heating using it(games, camera)? Its bound and normal to heat up, the thing is that to was hot to the touch and heated too much compared to others from what i have read
[Xperia Z2 General] Croize:
Sure it heat up, but not overheat :) What Celcius we talking about ? tell me a wery intense game i will try it, Well find out =) My lg g2 heated up way more, So hot that i rly could feel it almost hurt my fingers. I might found an issue, but i doubt its the phone, Slow charge? or maybe for all ? :)
[Xperia Z2 General] johannmint:
Sim

Can you please take a picture of "left sim not closed fully" i just wanna compare it with mine

thank you
[Xperia Z2 General] griffin_1:
I start to notice my current phone heating up when it gets close to 40ºc. This is by using the camera after a while and some functions, not something to heavy like a game.

I think asphault 8 is a heavy game, so its worth trying. I also don't game much, but i was just getting the impression that this phone will heat up excessively with just regular use to probably much more than those 40ºc (thats what i got the impression from reading comments)
[Xperia Z2 General] Xernoxis:
14W17 black

[Xperia Z2 General] bombdog:
You only see it when you boot the phone and it's in the top left corner and it's simply not noticeable any other time. Plus I have insurance and if I decide I want a new device well I'll just "lose" this one ;)
[Xperia Z2 General] Publicglutton:
Hey as long as your cool with it..;)

oh yeah 14W16.....no problems with my Z2 at all....:D
[Xperia Z2 General] HeartUnderBlade:
I agree, this would be a good idea. It'll give the community an idea of which batch contains the fixed phones.

I think you may be onto something. It does seem like the batches after week 16 doesn't have any problems and batches before or halfway into week 16 have a few problems here and there.
[Xperia Z2 General] Publicglutton:
Mine is 14W16..my Z2 is perfect .......so I do not think this theory is applicable....;)

Perhaps more likely to be where it was made and/or luck of the draw..
[Xperia Z2 General] alchopop:
14w15 here. Black received on the 19th April. No issues whatsoever and is the best phone ever had. Had smartphones since the days of the XDA IIi and nothing comes close to this phone
[Xperia Z2 General] hasona:
Mine is a 14W16 and in perfect condition regarding all the problems, hasn't really hot anything above 40 C which my Z1 did every time I surfed the web so awesome job by sony on fixing heat problems for me at least.

Off topic though I have no idea who the hell thought that having the SIM and USB at the same flap was a good idea!!! It's so freaking weird and uncomfortable that I wish they had two separate flaps rather than one big
[Xperia Z2 General] brouwerchris:
Received mine yesterday. 14w17. No gaps,I manually stopped 4 K video at 5.00 min,1 sec later overheating message appeared but video was saved.

On the label is a type number,does everyone have the same type number ?
[Xperia Z2 General] cedropol:
I have the same type no, Poland Unbranded, 14W16. No issues so far.
[Xperia Z2 General] ILS_SuperNova:
Guessing these are newest batch out if the numbers run in order.. Meaning these ones would have been made after sony knew about gaps/overheating...

Hope my replacement is a new one or even one that works.. 1080p failing after 2 mins is a joke!!
[Xperia Z2 General] TheOnlyIntruder:
Can't make a poll sadly, maybe a mod can insert a poll? Otherwise one of us will just have to run a tally every now and then and collate the information (I wont do it tonight because I am knackered).

Would you please find instruction in post #1. ;)
[Xperia Z2 General] BR4DOKYBrazil:
Tomorrow I will get my device, but the seller has already taken picture and is 14w17! Is that good?

Will I have any gap problem or have repaired the gap in this batch?
[Xperia Z2 General] ILS_SuperNova:
hard to say as some with week 17 reported no issue but my week 17 got to 7 mins on full hd and cuts off :(
[Xperia Z2 General] TheOnlyIntruder:
It's impossible to say at this stage, so far the results have been varied. The gaps seem to occur on earlier models but overheating seems to be fairly random.
[Xperia Z2 General] Croize:
You mean overheat as " youre device overheating " as a sign or just high c?
[Xperia Z2 General] griffin_1:
I guess high c. I mean it keeps heating up to a point where is umcomfortable to use. My phone after a bit of using starts to get warm, but nothing very umcomfortable (just annoying ). But the z2, people said it was almost hot to the touch sometimes and that also lead to the camera shutting down (i think they improved that) - but again, those were early devices and people are sayng that those from week 30 and up dont show those problems and other mentioned in the thread. Thats why i wanted to confirm?

[Xperia Z2 General] sam_conrad:
12w23. Just bought from never-msrp.

Haven't tried 4K, gaps don't seem massive but front top left and back right bottom have gaps. The phone is great, doesn't get too hot so far. The camera is ever so slightly off center, I noticed it right away since I was looking for it, but it's really not that bad.

The flaps don't seem to seal extremely tight, though they seal and stay...

Since I don't have a warranty, I don't think I'm going to be dunking the phone underwater anytime soon.
[Xperia Z2 General] rainreyes_325:
You should ask for a replacement if its under a 3 days or 7 days manufacturer defect replacement. But since its from ebay thats gonna be a problem. :thumbdown:

As i read gaps doesnt affect the waterproofing of the Z2

Sent from my C6502
[Xperia Z2 General] sam_conrad:
The phone isn't really defective.

It's fully functional, made pretty well. The camera is very slightly off center and the flaps seal, but they just don't feel extremely tight to me. Like I said, I bought the phone on ebay from Never-MSRP.

I just don't want to submerse the phone and find out it is defective THAT way, since I don't have full Xperia Care warranty support since the phone is an import.

Amazon just replaced my Z2, again, and it's ANOTHER W19 after they received new stock. Since I'm still having call quality issues, they said I can return it (my 4th) whenever I want and they'll refund my money. I'm going to wait another month or so to see pricing of the Z3, Note 4, and new Nexus devices. I'm terribly saddened with how BAD call quality is with this phone and the lack of QC on these devices. Especially since I'm totally in love with the phone itself (Design, battery, camera, etc)

3rd time lucky

Just got my 3rd z2 (w34) first one when back as up volume didn't click. 2nd one rear screen cracked got fixed then Nfc stopped and couldn't be repaired so got sent new one. Every thing looks good so far and I'd build quality better this time. First 2 must of been early weeks as received in April.
[Xperia Z2 General] sepzs:
I think you overact about "offcentered camera". Isn't there some tolerance when camera is still good with some offcenter?
[Xperia Z2 General] knoxploration:
Of course there is. The entire lens assembly is a single unit, and the window it sits behind is just plain, flat glass that has no optical effect at all. The lens isn't remotely wide enough to be shaded by the phone body unless the lens is right up near the edge of the window, which is a physical impossibility.

It is, essentially, not a defect at all and no reasonable person would complain about it or return the phone for it. It's a standard manufacturing tolerance, and well within tolerance.
[Xperia Z2 General] pepinocho9:
I've got a 14W22 also, I'm only able to record 4.5 mins of 4K video, then the camera app closes itself.

I can reopen the camera immediately and continue taking 4K video, phone got warm and cooled down almost instantly... I think my firmware (17.1.A.2.36) has some time restriction.

What do you think guys, is it performing OK or should I get a replacement?

My device has got warmer before (while using gps navigation on a hot car), without any warning, but it does warn when I'm recording 4K video and the temp is slightly up.

Also camera on auto flash will almost always flash. Kind of weird.

EDIT:

I made it overheat, the camera refused to start, I had to take 51 pics on manual mode continuously (20 mpx with flash on), then I recorded about 4 minutes of 4K and phone was hot, again, cooled down quickly. Question still the same.

Touch sometimes doesn't respond (rarely)

it does get warm. not hot enough to actually worry, but pretty warm. only while gaming and at the 2 hours i fiddled around with the xperia camera app on the stock rom. i downclocked the phone around 500 MHz for battery's sake and temperature. until the lollipop update is out, i don't even expect to need this much CPU power.

no hardware problems. case looks very well, no moving around camera lenses etc.
