I'm actually still deciding on Picking up the M8 or Z2 soon. Only against M8 because of the camera. So, you saying which Batches are good enough? Just 14w19? If I find anything other than that I should buy an M8 instead? Or just take the gamble? I would think that the overheating and 4K video recording and the likes are purely Software glitches and can be fixed by updates! :) Or custom ROMs of course. :D
[Xperia Z2 General] feis:
This is so out of proportions... and it shouldnt affect your decision at all. All problems are very very rare, except for minor gaps and 4k overheating. Gaps seems to be common in older batches, but the thing is they are so small, you wouldnt have noticed if not this commotion... And they dont affect usability in any way. That being said, no phone is perfect, go open m8 forum and look at build quality thread, which is basically 60pages of issues..
[Xperia Z2 General] shaf46:
go on for the z2 :) Just take the list with you and be friend with the seller, ask for the 14w19 or 20 batch ( as they contain less defects ) - and now all the devices have these defects but check out the defects on page 1 and try to get a better one and if these defect are not present in the phone then go and get it, to be frank with you i don't personally like the m8 :/ because of its camera nowadays you need a good camera :3
[Xperia Z2 General] feis:
M8 is awesome, very comfortable in hand, but camera is a letdown, and battery life was most important to me, thats why i went for z2. You wouldnt regret either way, both great phones, excelling in different things
[Xperia Z2 General] tel033:
will this off center camera problem affect the quality of the photos?

and does it really has the best camera in android?
[Xperia Z2 General] shaf46:
nope it wont affect any video / photo, and yes it is really the best out there :)
[Xperia Z2 General] rikues_gan:
my xperia z2 batch number is 14w17 and after about 1 week usage and some reading in this thread i finally found some defects on my phone

the front camera is slightly off center to the left

LED flash noticeably seen as slightly off center to the top from the hole.

recording in 4K makes the device overheat and force close, i can just record 4K video for 2:38 minutes.

after the force close i immediately record video in 1080p and i can record video for 9:50 until it got force close.

recording in 1080p 60fps has the same problem as the 4K one (overheat then force close)

screen has no gap though.
[Xperia Z2 General] shaf46:
keep it man :) sony should fix this overheat issue, have you try recording your 4k video on a 32 gb sd card ?
[Xperia Z2 General] rikues_gan:
using sandisk 32gb sd card and i can record it for 2:09 minutes.
[Xperia Z2 General] shaf46:
i suggest that you wait for a firmware update can you please provide a picture of your sony z2 back info placed on your box ?

is there written the batch number on the back of the box ?
[Xperia Z2 General] rikues_gan:
I don't see any batch number written on the box.

Only imei and some other informations.
[Xperia Z2 General] shaf46:
can you send me a picture of it in my private message please ?
[Xperia Z2 General] raducanmihai:
14w15/ .69 TW firmware (Vodafone Germany, unlocked, unbranded, bootloader unlockable YES)

- Very, very, very small screen gap, almost undetectable (face, top right corner)

- Small back camera misalignment (works ok though)

- No dead pixels

- On 4K I had mixed results: from 5-6 minutes indoors (with overheating message) up to more than 10 minutes outdoors (in about 15 degrees C), no overheating, I stopped the recording, but with audio/image delay.
[Xperia Z2 General] iArvee:
14w17. I can agree with the gaps in the top and bottom right. Flash is not that off-centered. Front camera is fine, back camera is not off centered. Overheats during recording.

Other than that, seems like I was pretty lucky with this one!
[Xperia Z2 General] samppis:
So there is no conclusion for now? It seems like the imperfections are found in all batches?
[Xperia Z2 General] rpk12:
Dead-pixel or not?Confused

I got the Black version(14w18).Have a small gap on the top,no gap at bottom.Camera off-centered.Last night i spotted something at the top right corner of the screen, A very very very tiny white(not actually white,lets say colorful when you see it at different angle) dot only visible if the screen is fully black and have a brightness of 95-100%.You have to look at it very very closely(If you have OCD like me)to see the point.If the screen turns to blue.red or green or any other color it is not visible at all even at 100% brightness.I thought it is a dead-pixel.

So i went to the service center today to show them and ask them for replacement they look at it and said it is not a dead-pixel.If it was then it would be visible at any color,at any brightness not only in the black background.So i asked a friend who experienced it in his laptop,he said in his case a green pixel was always visible at any background and that is dead pixel.Any way guys at service center denied my request.

I am very confused of whether it is dead pixel or not?Help me guys!!!Reply soon.:mad:
[Xperia Z2 General] natkaen:
It's a stuck pixel. i had about 2 on my old z1. There's a slight chance it'll go away, but for my old z1 it didn't go away. I even tried the stuck pixel fix on youtube and that made it worse.
[Xperia Z2 General] shaf46:
hi,

Is it like this ? and could you post a picture of it here please ? I think yes it is a dead pixel argue with them and say that on lots of different forum people with sony z2 and expert says that is a dead pixel and if they don't want to exchange it, tell them about the gaps ? wtf you buy something really expensive and there's gap ? lol its just like buying a ferrari and in the windows there are gaps but no water drops get it still it annoys you ! so you need to get a perfect one because your are paying and its not your fault :)
[Xperia Z2 General] rpk12:
What to do?

It is not that big.They told me that gap won't do any harm with waterproofing.And that pixel can only be seen in black with full brightness.Not in other background or less brightness,Why is that?.I think if is it a dead pixel then it can be seen in every background.ryt?
[Xperia Z2 General] shaf46:
mate , it is the starting point of a dead pixel :) sooner or later it will become bigger for sure, and if you're okay with the gaps it is fine but i wont never pay for a expensive phone and get a defective one
[Xperia Z2 General] rpk12:
I understand that.They will replace it when it become bigger they said and by the way in India Sony offers 6 months accidental damage warranty.If they don't change it "accident can happen purposely".you know what i mean.:laugh:
[Xperia Z2 General] shaf46:
haha i can speak hindi , hello hi bye , khaisé ho ? thik hai bhaiya ? haha im from mauritius just been to india 5 yrs ago x3 ofc man :3 throw it then say op :eek: ma gawd haha
[Xperia Z2 General] iAMOA:
any update on the gap issues or any new batch in process? ;)
[Xperia Z2 General] shaf46:
go for 14w20 ;)

dont forget +1

Vodafone NZ 14W18

Received Friday just gone
[Xperia Z2 General] AndroidInsanity:
Wish someone would make a poll, really want this device but I don't want to have issues.
[Xperia Z2 General] iAMOA:
mate, i was thinking to wait for another month till sony finds some solutions for this. what do you suggest? will they be able to sort it out or this will continue?
[Xperia Z2 General] Dpk1:
What you have is called a stuck pixel (pixel unable to switch off). Such pixels may appear as a bright dot of varying colours. On a traditional lcd these can come and go. Dead pixels are the ones which can't turn on (i.e permanently off) and appear as black dot(s). Dead pixels can't be undone. I've had my past phones replaced for even one single stuck (bright) pixel.

Try another sony service center and ask them for a replacement. Or you may directly email to sony regarding this issue, I'm sure they will help. Good luck!
[Xperia Z2 General] rpk12:
The good thing is Sony xperia support called me this noon and asked me that if i was happy of their service or has my problem been resolved.I said i am not satisfied with the service.I complain about their product and also told that about the guy at service center who try to misguide me.

Again i repeat all the problem i have to the support guy and he requested me to go to service center once again and let him talk to the service center guy who misguide me and denied to replace.He said if the phone has hardware issue they will replace it.God know what will happen:(.Pray for me guys.Thanks for the advice.
[Xperia Z2 General] shaf46:
mate i had 3 z2 till now for testing and stuff so far the two of them was execellent no bug no lags no 4k heat msg and no gap really premium ones but wait ill the end of the week im receiving two again ill shout out my review about it :) so long as you're buying your z2 there's no gap no bugs its fine :) but if you wait price will go down , bugs will be cured and better examples will be on the market :)
[Xperia Z2 General] shaf46:
Force them for a return , take your receipt with you take some pics about gaps / issues ( page one ) print it out and handle it to the guy let him see :P i did that lol and i got my return
[Xperia Z2 General] iAMOA:
you surely are blessed with perfect Z2ssss. :D plus, you told me that week no. is written on the box with imei but someone said its not so can you please take a picture of the box with and/or without week no. on box? :)
[Xperia Z2 General] shaf46:
i made a mistake my friend its not written on the box but you know what before you buy something you got the right to check it at every angle :D so print page one and take it with you why you check the phone just open the micro sd slot and slide the small black square and it should be written over it :D Check page one pleasseee and keep updating us with it, i get all my mobile from dubai :P
[Xperia Z2 General] atif_afzal:

[Xperia Z2 General] iAMOA:

[Xperia Z2 General] Blade1000rr:
I have a 14W18 handset, UK unbranded..

I have noticed haptic feedback is very weak and not consistent whilst using the keyboard (both stock and SwiftKey).

It isn't working properly on the home, back and recent apps buttons either. It's extremely faint, and a lot of the time doesn't vibrate at all even with 'vibration duration' turned up to the maximum.

Sometimes it will get stronger if you repeatedly tap a key (but not always).

It works fine in the Diagnostics app and notifications, ringer etc, but not the keyboard or home buttons..

I thought it was a firmware issue, so I flashed the German .402 firmware today, but it's still not working properly.

I have checked all the vibration settings and durations in the phone menu and in the keyboard menu but nothing will get it to work properly.

It's just something to be on the look out for, I know a lot of people don't use the haptic feedback function, so mightn't be aware of it, but I'm personally not prepared to accept anything less than a perfect device after the money I paid for it!
[Xperia Z2 General] shaf46:
i buy for my mates from dubai :) they give me the cash i give it to a local retailer store and they get the phone to me :)

try looking at this website the price are good :

http://uae.souq.com/ae-en/sony-xperia-z2-d6503-16gb-android-os-4g-lte-+-wifi-black-6901969/i/

the best price you can get around 500 euros :P

Get it from there

or look in deira all my phones comes from dubai
[Xperia Z2 General] shaf46:
mate once i got a z1 from france and the vibration was like' buzzzziii buzzziiiit ' and i had to turn it off but you can fix this :3 get a magnet switch of the device , the stick the magnet opposite to the back of the phone where the vibrator is position ( z1 - top , z2 - down ) then switch it on and it should get back to normal
[Xperia Z2 General] Blade1000rr:
Thanks for advice, will give it a try, but I have opposite problem to what you had, in that it's not working at all most of the time rather than being too loud!
[Xperia Z2 General] shaf46:
try the magnet and if that doesnt work i think we have to change the vibrator if it still on warranty send it back immediately
[Xperia Z2 General] Blade1000rr:
Tried the magnet alright, no effect.. Only have phone just over a week so returning to Amazon for an exchange for a new Z2..Thanks for the advice anyway. :good:
[Xperia Z2 General] [kEkA]:
Sorry mate, but I have to ask you, what do you mean by magnet switch of the device?

I'd like to try this since vibration on my phone is really loud, no sense using it on silent mode really :D

Is that some special magnet or just an ordinary one?

Thanks in advance!
[Xperia Z2 General] rubytuesday007:
14w18. Only issues I have is gap in lower left and 4k crashes at 2 minutes. Otherwise, great phone.
[Xperia Z2 General] shaf46:
keep the magnet aside, switch off your phone and try to position it back to back of the vibrator ( refer to tear down of z2 online )

ordinary ones but it is defective though

the part : http://www.ebay.com/itm/Genuine-Son...K_Replacement_Parts_Tools&hash=item4d1ce11f34 it is really easy to change it
[Xperia Z2 General] [kEkA]:
It probably is easy when you know how to do it :)

I took mine 5 days ago via Telenor, its perfect phone except this, should I take it to service for maintenance?

edit] I just googled for z1's vibration problem, its not like that, its just really loud :D dont know if thats normal
[Xperia Z2 General] shaf46:
take it to the repair center before weird stuff happens that why you have warranty brah
[Xperia Z2 General] Devzz:
Batch 14W16 ---

Hardware issues:

No physical defects whatsoever (no gap, camera perfectly centred, no dead pixels)

Software issues:

- Phone froze twice, had to soft reset (volume up button + power) twice within a span of a few hours. First time screen froze on lockscreen pattern, second time screen would not switch on no matter what button pressed. Both time notification light blinked due to receiving messages.

- Sometimes after charging or using the USB port or just restarting the phone, I get the 'close flaps' message but it doesn't disappear on closing of flap and sometimes the message appears even when the flaps are fully closed.

- Bit of lag with the recent apps menu.

- Had camera shut down on me twice or so due to temperature rising too high - Please note this did not happen on the previous Z2 although it was the same batch and I could easily get a few minutes of 4K with no problems.

- Battery monitoring problems- Had to clear data on Eco mode controller and factory reset to get STAMINA mode working properly.

Will edit with any other issues. If anyone has solutions to the software issues could you please let me know! Thanks! :)

EDIT1: update for you guys - just had to soft reset the phone for a third time in 24 hours. I have a feeling I have a dodgy battery or battery monitoring system at least as I have these massive gaps on my battery usage charts too. Additionally, I charged my phone to 100% and unplugged it around 12:58pm (UK time) and at 14:45ish I have 87% battery (data usage off, not on 4G) left. Either there are too many wakelocks or something is wrong. I tried to attach screenshots but the site won't let me due to "low memory" but I will be going in to store now to get an exchange.

EDIT2: Car phone Warehouse changed the phone. This time its 14W20. Perfect phone. Battery issues gone, no physical defects whatsoever including pixels, gaps and all. Have to try heating issue with 4K later unfortunately but for now it is absolutely fine!
[Xperia Z2 General] shaf46:
Thanks a lot mate :)

I guess a new firmware update should fix these up :) lets wait
[Xperia Z2 General] rpk12:
Xperia support team just call me again and told me that they flagged my problem on their system as i purchase an very expensive device and not satisfied with it so they will look into it.I suggest him that is there any way that i can send a picture of the issues i have and they give me a maid id.I also force him to replace not repair.I said if the device goes for replacement then the back panel will be opened,adhesive will be weaken and will be less resist to water.There will be scratch and dust particles will be inside the screen,in this case i will not accept the device.I am using for four days and not even make scratch or something and how i will accept the device after repair like this?

he assure me that nothing like this will happen.So just wondering what will happen.:p
[Xperia Z2 General] shaf46:
still when you get it, do a water test check it from every angle for light scratch, if its closed down properly you're paying dude so :D check it well if non ^ ^ replace
[Xperia Z2 General] edzilla:
14W18:

Not really any gaps, camera off-center (both front and back), severe overheating problems (even when browsing with chrome), bad battery life (not better if not worse than my year old HTC One).

I contacted Sony Belgium who told me they won't deal with me directly, I have to go through the online retailer.

I contacted the online retailer this morning, and am waiting to hear back from them.

I'm pretty sure it's going to take very, very long to get them to accept the overheating problem (I won't even mention the off-center camera, they'd probably laugh at me...), and I'm very disappointed I spent so much money on a phone with such issues.

Edit: I just did the video test, the camera force closes after less than 2 minutes of 1080p. The 4K closes after less than a minute.
[Xperia Z2 General] rpk12:
I am not gonna send if for repair.I want replace and i make them clear about that
[Xperia Z2 General] azharshaikh7866:
14w19

Top right gap

Bottom left gap

Both camera off centre

Heating...although battery life is gr8.. No issues in using phone....but a bit concerned about the top right gap

sent from Sony Xperia Z2 D6502 purple
[Xperia Z2 General] shaf46:
shame, mate write a strong email to them and says that you do reviews on youtube and you have a lot of fans if you point out these issues this will be a very bad image of sony so im trying to fix this issue with sony officials

your email should have details like : date of purchase, chassis note , imei and all and take the page one of this thread attach it to them saying that your fans gave you reviews about their sony z2 so far these are the defects.
[Xperia Z2 General] edzilla:
I'll try it first with the online retailer, and if it goes bad, I might just try this idea.
[Xperia Z2 General] cheetah2k:
14W17 and I have bright white spots (2) on screen. On a white background the spots are about 2mm in diameter and slightly brighter than the surrounding pixels. With a black background they are not noticeable, grey can see them as well.. :(
[Xperia Z2 General] shaf46:
be always soft with them and if they are being *****y then hit something hard :3
[Xperia Z2 General] shaf46:
wow thats huge man :/ try to get an exchange ????
[Xperia Z2 General] rpk12:
I took some of the picture of my issues and pointed it out before send it to the xperia care.
[Xperia Z2 General] shaf46:
hey mate can i take your picture and put it on the first page :) ?
[Xperia Z2 General] corallus:
Could everyone check the top left corner of the plastic surround,

Is it fully formed?
[Xperia Z2 General] AndroidInsanity:
OP can you PLEASE make a poll ? I want to know how common these issues are before purchasing!
[Xperia Z2 General] shaf46:
all the info are on page 1, the one with less issue is the one to buy :) BUT HOWEVER YOU MIGHT GET ANYONE FROM ANY BATCH THAT HAS NO DEFECT OR ISSUES
[Xperia Z2 General] The Gunner:
Guys, many of users here in Italy forum have bad fotocameras,mine 1w17 is also not perfect,focus on center but bad details on the sides.
[Xperia Z2 General] shaf46:
what do you means bad details on side, Sir ?
[Xperia Z2 General] corallus:
On some cams, there are small patches of blurred areas at the sides of images.

At the edges is blurred most of the Z2.

Why Sony?
[Xperia Z2 General] shaf46:
Because he has set his camera mode on manual at 20.7mp and you set yours at 13mp ( superior auto ) :) change it and give it a try
[Xperia Z2 General] The Gunner:
No,both are taken 8mp manual mode,iso 50.
[Xperia Z2 General] shaf46:
Now im confused :o
[Xperia Z2 General] The Gunner:
Unfortunately the 9/10 of Z2 in my italian forum shoot like this.
[Xperia Z2 General] cheetah2k:
Just took mine back. Has been diagnosed ELF (early life failure) and will be replaced when new stock arrives this Friday... The thing I'm worried about is that my screen is perfectly centred, no gaps, and the camera is all good.. I can even record 4k for about 10min without issues. Hoping the next one is also ok.. So angry the white blotches on the screen. Sony WTF so many issues with your screens!!!??? :(
[Xperia Z2 General] suman_pal78:
Mine from kolkata and it's 14w02 I repeat is 14w02 and NO ISSUE AT ALL

Anybody else got such batch no
[Xperia Z2 General] rpk12:
Yes.of course.
[Xperia Z2 General] King Cole:
Week 17 with no issues. Though, I honestly can't see what this 'gap' is, I don't seem to have it.
[Xperia Z2 General] shaf46:
:/ it might be a firmware issue or an issue with the camera itself :/ i can't really tell, if i had one in hand i whole tear it down and see :/
[Xperia Z2 General] shaf46:
that's what happens when they sit around and don't work on a fast rate :/
[Xperia Z2 General] TheoDores:
Same as me.

The difference is I still using .55 . I just updated to .402 yesterday and didn't test 4k yet.
[Xperia Z2 General] shaf46:
:o you got the second batch :D
[Xperia Z2 General] shaf46:
This is a gap
[Xperia Z2 General] Bazsty:
Wait a minute, are you talking about this?

Copy this link:

talk.sonymobile.com/t5/image/serverpage/image-id/12667i42C41B36091FAB2C/image-size/original?v=mpbl-1&px=-1

The plastic on the upper left of the frame doesn't seem formed properly on mine either.

I also happened to stumble upon this image on the internet which has the same problem too...

Link:

static.trustedreviews.com/94/00002bc3d/0ab4/z2-speaker.jpg

Is this a widespread problem? It bothers me only because the build quality on such an expensive device should be damn near perfect, and this isn't. It's not so noticeable indoors, but take the phone outdoors with the sunlight reflecting on it and it looks awful. It catches your eye and cheapens the look of the phone.

I seriously wish Sony would have used a different material, even the plastic on the Z1 is a lot better.

For anyone wondering, my phone is a 14W15 made in China, has small gaps on the top left and bottom right of the front of the phone, and a slightly off centre back camera lens.
