I endorse what you write.

I was not going to become involved in a thread like this as its pointless in every aspect. This sort of amateur quality control boils down to zero research of true value and ends up scaring people. If this thread had not been started and gone South as it has, how many members would have even noticed some of the so called 'defects' that are mentioned?

I began to ponder if one poster here was perhaps 'maybe' a clever Samsung or Apple fan boy as the damage being done to the Z2 in this thread is absolutely absurd.

I spent 5 years in my youth qualifying in the area of mechanical engineering quality control and so much poor uneducated information has been passed on here regarding tolerances of glass etc. Materials have expansion and contraction qualities and alloy's bonded with glass have to have some tolerance space or it will either fracture the glass or warp the alloy frame. Some are speaking about paper thin tolerances and calling them 'gaps'. These so called gaps are there for a purpose and are not manufacturing mistakes, the phone is designed to fit within given tolerances.

I am NOT excusing the odd lemon. Lemons will always appear in every device ever made even by NASA, top Swiss watch brands etc.

I suggest owners stop placing their Xperia Z2 under a microscope and enjoy them until, or IF, a problem arises. AS for batches.......One is in the land of fantasy here. There is no way we could ever know the months production run and thus no way an accurate figure achieved of the return rate. I guarantee their will be lemons in every months batch. I also guarantee that this will continue as in every device made by every manufacturer.

I do think some posters in this thread are trying to help. I also smell something off and I am simply not going to eat it.

This is a brand new mobile and it takes time even for Sony to correlate the production numbers in terms of returns and professional research performed by their QC department.

With respect I suggest no one even looks at the manufacturing data, nor places great stock in some of the nonsense written by a few here regardless of how well meaning or otherwise they may be. IF ones mobile has a genuine fault it matters not what batch it comes from what matters is the mobile is returned for examination.

Causing anxiety and paranoia like this is an unwise thing to do and even more unwise to give such ill-gotten information any real credence.

Sony is developing a very strong reputation for the quality of its mobile phones. I have owned the Z and still own the Z Ultra and have taken delivery of the Z2 today. I am a very fortunate person in that I have choices to make and I choose Sony because of their QC.

Regards,

Ryland

Every batch will have production issues. Honestly, there's no way for you to know that the 15th batch is good. Think about how many people report that their phone is perfect. Of course more people will report issues on these forums, logically and statistically speaking. Not bashing your effort, but if people were to wait for the "perfect" unit, they could be waiting for a long time. Long enough that the model becomes obsolete, and that theory isn't just with phones but with most manufactured products. And because of the limited availability of the phone and the volatile price range, sometimes, beggars cannot be choosers. Of course if you have the patience and the money, by all means wait for and pick the one that satisfies you.

I purchased mine the 28th of May and got the black color. I noticed a few nicks on the frame. Very tiny but I peered over the phone long enough that I noticed it. Once again, not sure if it's manufacturer or the seller misrepresenting :X

Phone functions fine though, haven't tested waterproofness.

14w20 - Zero Defects :) :)
[Xperia Z2 General] logzz:
14w20 here too and I have zero defects. But I have had to purchase two as my first one 14w14 did have the gap at the top of the screen and off center cameras. I wont settle for one with gaps and that as the build quality of them is quite poor. 14w20 build quality is perfect. no dead pixels, cameras center. no gaps.
[Xperia Z2 General] sharingspider:
Yeah however Camera Heating Issue still there & I recon that is universal across all Models.
[Xperia Z2 General] logzz:
it is universal even sonys compact cameras do it. they sensor can only handle so much information recording at such a high resolution before it gets hot. it did not even come as a surprise to me when I read that. its the same reason other phones such as Samsung and the likes of can only do 5 mins of 4k recording. no different to playing a game on the phone and it gets hot I remember some phones used to dim the screen at high temps
[Xperia Z2 General] sharingspider:
Being my first Sony Device - I just felt that as a flaw & Its just little bit more in weight compared to Note 3 as well.

Also Note 3 never used to dim or get hot at all - I am only talking about N9005 variant as Indian Variant of that is crap as well.

Any useful things you can do with the band? Also there is very minimal development of Z2 as well compared to other devices & Big Drawback to Root too.
[Xperia Z2 General] logzz:
I dunno I have the note 3 and the xperia z2 infront of me right now and am probably going to sell the note 3. battery life is a bit up and down on the note 3. ill muck around with both for a bit but I think I will keep the z2.
[Xperia Z2 General] sharingspider:
Guys also If anyone could help - My Contacts from Google are not syncing - Shows syncing error try after sometime since 2 days. However rest everything from google did sync. Also when I dial number I know it is showing the right name of that contact n picture however not reflecting in contacts.

Anyone has any clue - Thanks in Advance.
[Xperia Z2 General] SexyIceCream:
keep in mind that the S5 can do these 5 min recordings consecutively until space runs out, so it has nothing to do with the heat issue. i am quite disappointed with sony on this...
[Xperia Z2 General] logzz:
Im having the exact same problem not sure whats up with it but only half my contacts will sync
[Xperia Z2 General] shaf46:
TO ALL THESE PEOPLE BEING JELLY OF THIS THREAD OR WHAT EVER ! YOU'RE PAYING 750 EUROS FOR A DEFECT PHONE :eek: OH I SEE, SO THE PHONE SHOULDN'T BE PERFECT RIGHT ? AH YOU JUST SAID IT RIGHT, YOU CAN USE PHONE LIKE THAT BUT WHEN YOU GO TO DIFFERENT SHOPS AND SEE THAT ALL PHONE HAVE GAPS / NOT PROPER PLASTIC FILLED IN, CAMERA LENS FITTED BUT THERE'S GAY AROUND THEN, YOU WILL BE FRUSTRATED AFTER LAYING IT IN WATER AND WHILE IT CONDENSE SO FAR , HATERS WILL HATE , POTATO WILL POTATE

HERE'S A LIL STUFF FOR YOU : https://www.youtube.com/watch?v=UxxajLWwzqY
[Xperia Z2 General] vctrdnl:
Why do you have to be so offensive and aggressive, I don't get it. Fine, you made a mistake buying a Z2, you regret it, so then just get rid of it - return it or sell it. It's hardly the end of the world, especially if you are able to afford spending such a handsome amount of money on a handset. I agree, Sony should improve their production process and most of all, their quality control. Anyways, your constant bashing and ranting is far from useful and constructive. We got your point, at least some units from early batches of Z2 have manufacturing, rather cosmetic issues. However, not all devices suffer from such problems, I can assure you because I saw and tested a perfect device meant for mass sale a couple of days ago (actually 2 devices, black and white). You saw 1, 2, 3, 5, 10 devices with subpar production quality. Fine but that's not the whole production by a long shot. Thanks for the fair warning, but please stop this madness with aggressive language, caps lock, etc. Jeez! It doesn't solve anything and it doesn't help anyone.

I am now on my 3rd xperia z2, the first one had a gap between the frame and the lcd and was a 14w14 one. the next one was a 14w20 which was much better, but after looking very close I found a crack in the frame where the sim card slot is and water would have gotten into the phone. Also the cameras were slightly off center and when I received the box it had already been opened. Also both the previous ones the mesh where the top speaker is was not inserted properly and did not cover the speaker hole properly. I am now on my third one which the staff in store opened infront of me again this one is a 14w20 but it is the most perfect one I have had yet. All cameras perfectly in center no gaps at all anywhere between frame and screen. If you have gaps between frame and screen I highly recommend you get it replaced.
[Xperia Z2 General] feis:
I have gapps(if u can call that a gap) top right, bottom left, 14w16, and no, im not gonna go and exchange, phone is working perfectly, why would i??
[Xperia Z2 General] logzz:
it up to you in the end but I just got annoyed at the poor build quality when paying $900 for a phone. The z1's never has these issues or the xperia z. this is the worst quality I have ever seen. Im happy with my 3rd replacement but probably will not go for a sony phone next time around.
[Xperia Z2 General] King Cole:
I have a week 17 (which seems to be the one that people are reporting the most issues with), but honestly don't really see any gaps or anything. Maybe I'm just not looking close enough, but the phone itself works fine (both above and under water).
[Xperia Z2 General] logzz:
its not batch related as far as im concerned. some have the issue some don't I don't think I don't think it matters what batch they are from. If it looks good keep it don't take a chance on one that could be worse
[Xperia Z2 General] NetSkill:
I think this has nothing to do with batch numbers... Mine is 14w15 (vodafone DE) and its perfect no gaps, camera is centered properly, never saw overheat message while using camera

Odoslané z D6503 pomocou Tapatalku
[Xperia Z2 General] blab86:
Mine is a 14w15, slight gap top right, bigger gap bottom left, camera of center, 4k video playback lags sound, also a crack appeared on back, 100% I haven't dropped it or damaged it. I noticed it as soon as did a video, not 4k I turned it over and there is a single crack from top to bottom, I will post images as soon as I can. Apart from the slight defects, I truly love this phone it's amazing.
[Xperia Z2 General] [kEkA]:
I've already posted here about vibration "problem" which turned out not to be a problem

my batch is 17, no gaps, maybe 1 in on top left corner on front but I'm not sure if its a gap at all, it has to be the smallest one if it is :D

I've been using my device for 2 weeks already, and I cannot say if I was ever happier with my purchase and choice as now.

Until today, I had no problems only 2 "scratches" on back and I'm not sure if they are scratches at all and they appeared after 3 days of buying the phone. But ok, they were hardly visible at all so no problem with then.

Today at the strong sunlight, I took the phone out of my pocket to change the FM Station and to see why was it so warm, on my surprise I found something that on first glance looked like a big scratch on front screen/glass. I didn't worry much, as I thought that it was just dirty, so I arrived at home, cleaned with special fiber towel and some screen spray and on my surprise found that

whole

front screen is in some tiny little "scratches" which appear on direct sunlight and look more like cracks, which they are.

Notes:

-I've been extra careful with the phone, no drops, no pressures, no playing games making it warm, no dipping in water, no leaving phone on the edges or in pockets for long time, no sitting nor running while phone in pocket, it's in pocket only when I walk and I do

not

wear any skinny jeans or have small pockets or with any other objects with it and i take caution even when walking with phone in my pocket about it.

-As I said the batch is 17, in camera mode it gets fairly warm, had only once overheat message and that was when I played game and then tried to make 4k video and after few days I tried only once more 4k for about 4-5 mins, no message, never after that and I'm taking photos on daily basis. I think it's safe to say that i have overheat problem in general, since it gets sometimes even hot just when using radio or browser, I won't even talk about games, had only 1 and it was damn too hot after just few mins playing it.

-My battery lasts one whole day, with some % left after that, average screen time is between 4.5h and 6h, and i noticed that between 70% and 100% it discharges really fast. Only browsing takes my % too. I use it for viber, calls and messages mostly, and i said i take few pictures, maybe 4-5 max per day.

I bought it in Telenor, I brought it there and they told me that it's clear to them that it wasn't dropped or put pressure on it as the cracks are 'random', some of them quite long, and no impact spot and I repeat, they seem to be in early phase of evolving as they are thin and not that wide and not visible if not under strong sunlight,

but they all appeared in same time I think. One is even visible even when not on direct sun light as of today.

They said they will take it on Monday and give me a call within, usually, 10 working days with solution,

any opinions?
[Xperia Z2 General] kannanX10:
i think u misunderstood it might be the digitizer(its visible in sun/close inspection of the screen at diff angles)
[Xperia Z2 General] changkho1908:
my old z2 has that problem too, i gave it for the staff at store, they tried to clean, but not successful. after 4 days, they called me to come for repleace another one. i come to get new one.
[Xperia Z2 General] [kEkA]:
I'll try to take some pictures of it now

EDIT] I know whats digitizer and its grid, its not like that, I cannot take picture from this angle, its too reflective but it can be seen when held in hand.

They look like first 4 pictures

I know its sony xperia z but mine looks like that just little less visible, as they didnt evolve yet

cannot put pictures, no 10 posts yet :\

[Xperia Z2 General] blab86:
Also forgot to mention, my sim card cover keeps coming lose as well, and it does get really hot when shooting video,

here are some pictures i took of my defects. sorry about the quality, but you can just make them out.

Would the crack be covered under warranty?, as like i said i never dropped it or damaged it in anyway, i take really good care of my phones.
[Xperia Z2 General] [kEkA]:
Yes apart this, its a perfect device..

edit] and btw my digitezer grid is visible always on direct sunlight
[Xperia Z2 General] blab86:
you have just reminded me, mine is visible as well in direct sunlight
[Xperia Z2 General] shaf46:
I can smell jealousy here, just do your own thread and don't waste your time on mine because i don't have time for you

note : This is a basic thread and data has been gathered from people like us !
[Xperia Z2 General] Dpk1:
I agree with a few posts above. This defects / gap issue has been way too overblown! I mean, this thread would have all of the readers believe that even the slightest gap in the chassis is a defect which would compromise the water resistance of the phone, whereas in fact it is / does not. There might actually be a few initial batches with real defects / issues but that couldn't be true for majority of retail units. I had no gaps on my Z2 (14W18) which I had replaced for touchscreen issues, but have a slight gap (not noticeable on normal use) on my new Z2 (14W20). Neither of the phones had issues regarding water resistance.

There are / might be other more important issues to check on the new Z2 than the so called gap / off centre camera issue, such as any abnormal tint / stuck dead pixels on screen, abnormal touch sensitivity, call quality etc. I have none on my new Z2 BTW.

Anyway, I do not intend to defend sony for any defects or manufacturing issues which maybe genuinely present on a few units / batches. I would rather want sony to vastly improve it's quality control. All I'm saying is that people should be careful and aware so as to make out the real issues / defects from so called gap / off centre camera issues (which I'd label as cosmetic issues at best), as having replaced your Z2 for the latter might leave you with unit(s) having worse issues.
[Xperia Z2 General] Saqib Nazm:
Thread closed, this thread will eventually get more derailed with time as you guys have already noticed. And there is no point of discussing defects that a phone may have because this cannot be fixed here, If anyone feels they are unsatisfied with their device or any problem related to hardware they can take it to the Sony Care. So I don't see any purpose of this thread now, I hope you all understand. Thanks

14w16 and no defects at all. I managed to record a 14 minute 4k video without a force close. Haven't tried longer because it gets boring after a while.
[Xperia Z2 General] SkyS1gn:
14w18

Gap bottom left, upper right, 1-2 dead pixel or dust (zoom in), off center camera (slightly), left sim/USB door not closes fully.

Anyone has door issue like this?

14w17 Black

0.8mm gap at the bottom left.

Everything else seems good.
[Xperia Z2 General] prazvt:
14W18. No gaps & no overheating, just off center camera lens (a bit up and to the left).
[Xperia Z2 General] kamalaggi:
I've just done a waterproof test on mine and everything seems ok apart from the double tap to wake which has actually improved. :)
[Xperia Z2 General] shaf46:
i think thats mainly a firmware issue, what you think ? :)
[Xperia Z2 General] shaf46:
Thank you for your review, i will add it up :)
[Xperia Z2 General] kamalaggi:
It was really bad before i dunked it in the water.
[Xperia Z2 General] shaf46:
maybe defective one mate :/ try to get it exchange for the new batch 14w19 seems ok till now
[Xperia Z2 General] deepgrass:
It would be better if there is there is a some kind of table

that count how many user have each issue at each batch.

This would give indication of defects rate at each batch.
[Xperia Z2 General] HOmERCIdAL:
I have a week 14 with a 0.5mm gap top right and a slightly larger gap bottom left. Oh and keys not forget a slightly up to the right camera lens.

If there is a Sony centre nearby can they change it or do they offer a repair or is there nothing you can do?.

Just curious.
[Xperia Z2 General] shaf46:
Hey there, hmm if you have warranty : Yes, they will change it, if not they will do a water test then says that no its fine ! But if you're not satisfied ask them for a refund ! Say that you're really not fine with this and they should change it because the issues is definitely from them, hope i help :)
[Xperia Z2 General] shaf46:
Im trying to work on this, thank for the idea but to be frank with you im new on this forum and im trying my best :) if anyone can provide the table i will edit the thread and place the table there and update it with figures :) thanks
[Xperia Z2 General] HeartUnderBlade:
14W18 White Z2 here. Here is my list of problems I have and do not have:

I HAVE:

1: Very small gap on top right and bottom left. Honestly, it's so small that everybody I asked could not find the gap. I am able to fit ONE piece of paper into the gap but I am NOT able to fit 2 pieces of paper.

2: Overheating issue while recording 4K. Longest I can last is about 5-7 minutes (which seems to be acceptable to today's standards, in my honest opinion.)

I DO NOT HAVE:

1: Overheating issue while recording 1080p. In

NORMAL

conditions, I can record well beyond 10-15 minutes on 1080p, in fact, it went on for so long that I decided to just stop recording. I have yet to overheat even at that length of time. However, I did overheat on 1080p when I was putting my phone under a stress test while recording. However... that was a stress test so I did it on purpose.

2: Off-centered camera. I made sure I do not have an off-centered camera. I took my flashlight and shined it directly at the camera to eliminate shadows. It is not off-centered like some of the cameras in the example pictures that are floating around.

3: Yellow/red tint. At least I can't see any tint. If this is an issue, I'm sure we could easily fix it with white balance option.

4: Loose flaps. My flaps both close perfectly fine and tight. I did a water test and everything was completely fine.

5: Dust under the glass or camera. No dust whatsoever, however, I have dust under my screen protector! >:(

6: High temperature even when using Chrome. My phone does NOT get hot just by browsing the web. However, there is a temperature change when I'm doing stuff on my phone but nothing out of the ordinary.

7: Dead pixels. No dead pixels at all.

That's basically all the problems I have and do not have. There's nothing that affects the functionality of this phone to my standards and I'm quite happy with it.
[Xperia Z2 General] iAMOA:
can we find the week number from the box or something like that? like IMEI number etc. as i live in a country where once the box is opened the cell phone can't be returned because of SUCH ISSUES and it can only be then sold so can't risk buying a defective unit.
[Xperia Z2 General] shaf46:
Hello, Yes look on the box you should see something next to the imei number as 14w14-19

:) keep us update
[Xperia Z2 General] shaf46:

[Xperia Z2 General] GoldPunch:
14W16 - taiwan

Small gap on top right.

After 4 minutes - overheating message at 4k and 60FPS 1080p.
[Xperia Z2 General] hanano17:
14w12 only issue is overheating, which seems almost universal
[Xperia Z2 General] starbury:
aww man 14W7 with bottom left gap :( and I think the front camera might be a little of centre from the top (couldn't really tell).
[Xperia Z2 General] Kombian:
I'm on the 14w16. In addition to overheating camera(normal use) and the top-left gap on the back, I have a bottom-right gap, half the width of the top-left one, also on the back. Both back and front camera are off center, i.e. slightly upward. Haven't tested the double-tap yet, so I don't know about that.

I'm thinking about returning the phone, since the IP-grade might be compromised due to the gaps. Overheating camera might get fixed by FW update, but not a HW problem... :) Thanks for starting this thread.

Best regards,

Kombian
[Xperia Z2 General] shaf46:
Hey , Thanks for the review i suggest that you return it :) we can be sure in the long term :)
[Xperia Z2 General] shaf46:
Let's wait for a firmware update :)
[Xperia Z2 General] shaf46:
Don't worry it wont affect your phone but however if you can return it back just return it back for a newer batch :)
[Xperia Z2 General] shaf46:
Urgently need to know whether the batch number is placed on the box ! Anyone willing to take a picture of the information onto their box and paste it here ? Thanks
[Xperia Z2 General] AndroidInsanity:
Are these very common issues? Was about to get the Z2 but I ain't sure now
