Guys, I don't want to sound like a Sony hater, but i work for O2 and i have tried several of them and some have a yellow tint.

Disclaimer: Since i work for O2, i have to say that anything i say is my opinion and not representative of the views of O2 (Telefonica UK).

Me and my mate who work in the same store pre-ordered ours. We basically got the first batch with the free QX10 lens. All the customers who did this, our phone's brightness, viewing angles and colour saturations were all the same.... and they were good :)

Yesterday my mate needed to switch his out for a replacement. We unboxed a phone, set both our phones to max brightness and turned off adaptive.

Also i had a customer who compared mine to his.

Result: The new batch phones, as you tilt the phone, it has a yellow hue. Both my phone and my mates were clear white.

My phone and my mates have a serial that starts BH902A****

The new batch has serials that start from BH905***** to BH909*****

I hope that some of this info helps. The customer who compared his to mine, i just took it back straight away to send back to Sony and opened another box and the display was nice and white.

I work down in Kingston in London, if anyone wants a little banter and check the displays out :)

EDIT: My screen shows as JDI when i run the dmseg as su.

Also Bootloader is not possible to unlock with O2 Stock. Our demo direct from Sony says bootloader is unlockable. But all the O2 stock say NO. Damn it O2 :(

Yesterday I had my first experience with my Z1 as navi-device in my ultralight gyroplane.

Compared to my very old F7 navpad, Galaxy Note I and Galaxy S III the screen was fully readable even with full sunlight at 90° hitting the screen. Route and Bearing showed crisp and sharp like my other instruments (MGL Avionics glass cockpit)

Never experienced such a good screen visibility in direct sunlight

(even power drain was moderate: I lost 31% at a 2,7 hours flight at max. brightness, auto off, X reality on)
[Xperia Z1 General] Sean473:
I disagree with you about the camera! I seriously doubt the final firmware has been released and this has always been the case with Sony! It doesn't seem that the Bionz engine has been enabled yet and everywhere I read says that there will be a firmware update... Even a Sony insider/ someone confirmed that!

Thanks for the heads up.. I have 903 serial so luckily I'm safe :D... I thought there was a yellow tint but screen adjuster has fixed most of that... Flashed the central Europe .534 update on my unlocked UK LTE model and have been very happy as camera feels much better! Overall 8/10! More than what I'd give to my S3 which was a mega pain in the ass and couldn't see anything in sunlight!
[Xperia Z1 General] ruchirtrehan:
True, there is still many more updates gona come specially for camera and bionz and that's confirmed ;)
[Xperia Z1 General] Sean473:
Do you know where's the post where they wrote about the firmware update? Particularly the bit that Bionz is not enabled yet?
[Xperia Z1 General] lucky92:
I'm sorry but how to check the serial ?

Thanks in advance :)
[Xperia Z1 General] WouterNLD:
If you open up the SIM drawer. There is a small piece you can slide out. The serial is printed on there. It is also on the box.
[Xperia Z1 General] Ame123:
is there any proof that it is confirmed
[Xperia Z1 General] hoezay:
bummer

I have a BH904**** and the yellow tint. guess I'll go try to get it replaced. :( bummer.
[Xperia Z1 General] jos_031:
Mine is BH901
[Xperia Z1 General] romiros:
S/N BH902... Panel SHARP. Excellent viewing angels! Without color degradation. http://a0.sderni.ru/d/346407/2013-09-29_16.07.38.jpg http://a0.sderni.ru/d/346971/2013-09-29_16.09.31.jpg it looks like AH-IPS
[Xperia Z1 General] Sean473:
Mine is BH903 and is whitish after using screen adjuster!
[Xperia Z1 General] WouterNLD:
Display?

Have you got any problems with the display? Is it clear white? No yellow hue? Viewing angles?
[Xperia Z1 General] bucho2004:
I have a BH908 and no, it does not have a yellow hue, I know this because, I returned a Xperia z1 because of the black screen of death that occurred, and that z1 had warmer whites (yellow hue) compared to my current one, also I checked out an Xperia ZU. That also had warmer whites similar to my first z1.

So I guess you're info on screens based on serial numbers is flawed
[Xperia Z1 General] fallenwout:
I can confirm the bad displays. Because I wonder why people keep defending the z1 screen I went to the shop where the Z and ZU was displayed. And my z1 looks exactly the same as the z. Display on the zu was BEAUTIFUL. If those people z1 is like the zu, I understand their case.

But unfortunately my z1 does not have the zu screen. Even my wife thought the zu display was beautiful and my z1 looks ugly compared to zu.

I got a refund but if anyone thinks their screen is ugly, I can assure you it is! Because there is no way you can doubt the zu-like display quality. Viewing angle on the zu is very good.
[Xperia Z1 General] WouterNLD:
I have updated your serial in the thread (link). Nobody reported a BH908**** before. There are already multiple reports of same build number and same screen reports. I'm as curious as you if it will hold up. I will continue summarizing it in the other thread.
[Xperia Z1 General] DanteEx:
My Sony Z1 BH900B**** version seems to have pure white colour, without any calibration. Viewing angles are okay, but are slightly on the pink side at off angle.
[Xperia Z1 General] bucho2004:
I have read through my own reply, and it might have and I didn't mean for it to come out naive or dismissive. to be honest I am as confused as you, and everyone else regarding the different screen qualities of the z1.

Maybe there are different screens out there, or maybe my perceived understanding is, that there is a warmer white screen and a colder white screen on both the z1 and the z ultra.

as seen with my very own eyes. only difference is the viewing angles.

And the viewing angles on the z1 are all the same, but different depending on the persons perception and acceptance for them. I hope that makes sense.
[Xperia Z1 General] andybites:
BH902 - viewing angles are poor.
[Xperia Z1 General] rayan210:
I have the Xperia Z1 witch I bought it in the Sony Style store of Paris and the vision angle are pretty fine, I haven't the "White Curtain" effect ;)

EDIT : I have juste checked the serial number, it is the BH901, or BH9019 I dont know if I should take 3 or 4 numbers :p
[Xperia Z1 General] jonmorris:
I'm amazed too. My Xperia Z was seriously hard to see in sunlight, to the point that I had to put in maximum - and still struggled.

Today, I was using my Z1 outdoors and it suddenly dawned on me that I was having no trouble whatsoever - and it was set with the brightness on minimum (but adaptive on).

To be fair, it wasn't quite as intensely sunny as it has been when I used my Z outdoors in July/August during our (UK) heatwave - but I am quite surprised that the reviewers haven't been mentioning this in reviews - rather than talking about bloody viewing angles!
[Xperia Z1 General] zipolly:
My phone still shuts the camera down after moderate use because of overheating and according to Sony I have the latest firmware.... so what am I supposed to do with a premium camera smart phone that keeps shutting down.
[Xperia Z1 General] n4v1n:
I have a BH903 what settings did you guys use to get the screen more white?
[Xperia Z1 General] Geoffxx:
can you test the viewing angles in direct sunlight please - I'm sure there are some here who would like to know - we've got to cover every angle for the lazy squad who won't go to the store and look at it themselves lol
[Xperia Z1 General] Sean473:
You might want to flash the .534 firmware... It reduces the heat problems and the chances of this issue... That's the only way since Sony hasn't released anything for the UK... If you have an unlocked LTE model, flash the central europe firmware which is hanging around here!
[Xperia Z1 General] DeepEmbrace:
BTW guys, i only posted the serial number just so if there was any correlation, we might be able to pick up on it. So far from what everyone is posting.... there isnt :(

So please take it with a grain of salt.

The phone (so far 5 days in) is really nice. The screen protector in the box is not that great, but i would rather no scratches on the phone. Will get some sort of matte protector in the future.
[Xperia Z1 General] Cookie Ninja:
Great reading your post. I tried using mine but simply cannot find a place in the cockpit to stow the device (and it is not glove touch-friendly). In any case, the onboard avionics display more info than what the XZ can offer. Happy landings! Btw, what app were you using for VFR nav?

Dead Cookies leave no trails...
[Xperia Z1 General] troed:
For me the Z1 with Flymap Moving Map and Airnav Pro installed is the "second condome". My main Nav-system is MGL "Odyssey", but if it fails (which in 9 years never happened) the Z1 is my backup. And it is easier to record my flight with Z1 than to take out the SD-Card from MGL and transfer to a laptop.

AND: Z1 is my music server connected to my BT-Lightspeed-ZULU headsets ............. :D

BTW: nice app: iXGyro

Always happy landings
[Xperia Z1 General] grievous2004:
My screen has yellow hue issue.. Couldn't it be firmware related? I read that an user had this problem after upgrading to .534. What do you think? Can anyone confirm or not this? I am on 534 and definitely have yellowish screen. Thank you!
[Xperia Z1 General] demoniality:
Although proving it would be difficult i definitely noticed a change in screen hue after updates and comparing my screen to newly unboxed handsets confirmed this
[Xperia Z1 General] Tristard:
I was reading about the yellow hue and had a close look into my z1. display was fine, no issues found. updated the z1 today and noticed the yellow hue afterwards. it maybe happened by chance, but that's what I experienced.

would be great, so this yellow-bug could disappear with the next update... :P
[Xperia Z1 General] Soldier Blue:
This thread has almost every newly released smartphone trope ever. A small sampling:

- early batches are problematic

- new phone not better than old model

- lucky version numbers vs unlucky version numbers

- its only a calibration issue guys

- no you're wrong they're using mva/va/ips/ah-ips/tn/tft/tbh/wtf/etc

- firmware updates will surely save us

- even MY WIFE thinks X is better

- CONFIRMED, IT'S ALL CONFIRMED. LOOK AT THESE CONFIRMATIONS.

- subpixel arrangement is truth, get your USB microscopes people

- please close this thread it sucks

- dude what did you just say to me? I'm from POLAND

- my device is perfect and spectacular, sux2bu

- looks like im waiting for the next model [one year away form now]

- people photos of "the issue" with a wide range of competitor devices, in varying image/video compression, being viewed on infinitely diverse display and lighting conditions

- when is Brazil getting [this lustworthy hardware at less than 3 times its average market price]

I really wanted the Z and I've passed on almost every phone since the Nexus S for various hardware "flaws". The Z came closest to being the perfect phone and yet I passed on that because of the display and mediocre battery. This phone was supposed to improve on both and you'd think xda would be an authoritative source on the nitty gritty if there were some sort of lottery in place, but I feel like I got stupider reading this thread.

I'm just gonna buy the damn thing. :V
[Xperia Z1 General] aesopu25920:
Got the same problem after update to .534...

The screen was perfect for me before the update

Just a little bit of yellow hue

Hopefully Sony will fix this on next update
[Xperia Z1 General] ruchirtrehan:
If people are getting yellow hue issue after .534 update, then it's pretty much clear and nothing to worry that an update will fix it, give some time to Sony, the device is not even a month old, let the software settle down a bit.
[Xperia Z1 General] Tristard:
hah, nice. yup I hope so. saved a lot of discussions with the store for me, thanks for the confirmation ;)
[Xperia Z1 General] grievous2004:
I don't know if it's confirmed: I tried downgrading to 518 but the screen didn't get any better. Really don't know what to think
[Xperia Z1 General] drsoran2:
Exactly.

No one can and should reliably judge screen quality, colors and viewing angles from a picture on the internet. The reasons are simple:

Every digital camera is differently calibrated and thus captures photos with different white balance, colors, detail, saturation, brightness and sharpness. Then there is compression. Different laptop and PC displays also show different color ranges, white balances, sharpness, resolutions and so on.

If the screen on which you are viewing the photo of the Z1's screen is bad, then the screen of the Z1 will look bad as well or worse than it actually is.

Finally, everyone's own eyes perceive colors, saturation, etc. differently, it's a biological fact. There's also the difference between the color perception of males and females and to some people, the same color is more warmer or colder, more red or less red, for instance.

Therefore, one person might say that the screen looks good while to another the same screen looks terrible.

Once you know and accept this, you'll realize that screen comparisions via a digital photo are nonsense.

You could basically have the pic in black and white and people would still claim they can see "colors".

The only comparision which might be a bit helpful, would be if several people went to a store and looked at different screens hands on and with their own eyes.
[Xperia Z1 General] Tristard:
maybe it was just more like a confirmation for myself, so there is a chance I´m not nuts. fair enough to me (for the moment). ;)
[Xperia Z1 General] Tiu Fiu:
Just came here to say you've made my day, good sir... Laughed my ass out loud when I read the last (truthful) line (sorry for the bad language, but it was really funny as a Brazilian to read this)...

Now, if you'll excuse me, I'll get back to my lovely-yet-generally-unappreciated ZL.

Good day to you all, gentlemen.
[Xperia Z1 General] jos_031:
There is no yellow hue issue.. i put a white image in boot animation...and it was clear white. those who have issue try doing it to confirm hardware issue..
[Xperia Z1 General] ILikeTheWayYouMove2:
I have a bh908 and no yellow hue issue I did spend the most of the first 2 days with the phone with brightness to 100% as I was just admiring the screen improvement over my Z and to warm up the screen and glue (probably does nothing) as I read it on this forum somewhere it may help

Or maybe I just can't see it. I asked everyone does the phone have a yellow hue and they say no

So maybe it's just a placebo for some they think they may have so they do

I don't know, even if there is I'm sure Sony can fix it via update (heard that before lol)

And this screen is awesome in my eyes the colours just seem very real compared to my housemates s3 and dads note 2

FYI:I don't know alot about screen technology etc just what I read
[Xperia Z1 General] grievous2004:
I tried with different boot animations but I always get the same colours. I must say that, setting brightness to its maximum, white is not that bad but grey shows definitely the yellow hue. The boot animation is played at maximum brightness so the whites are good but other colours look the same..
[Xperia Z1 General] hoezay:
Check out this picture from the Verge. It seems to have captured the yellow hue problem.Look at the Z1 on the extreme left.
[Xperia Z1 General] jos_031:
I never thought the problem really existed..my phone dont have yellow tint i guess i was doubting myself... seeing your pic i guess i dont have.. but it doesnt feel pure white.. i did some test it was white.... but other display highlights blue a little.. to make white look whiter..
[Xperia Z1 General] ILikeTheWayYouMove2:
Yeh that's a great comparison photo just reassures me I don't have Bad eye sight and I don't have the yellow hue issue

But good comparison for those who are unsure

I'm not too sure it's a hardware defect though, but I could be wrong
[Xperia Z1 General] Crazy CS:
The Australian release was yesterday and i've had a look at a few units and all seem to have the yellow hue 'issue' - i bought mine from the UK and i just used the Screen adjuster app and will continue to do so until Sony update the firmware to include it or fix the issue.
[Xperia Z1 General] Geoffxx:
to me that just looks like the one on the left either has the brightness turned down or is a completely different screen as the wallpaper colours are not as bright either

and the google thing is a bad example as it is semi transparent
[Xperia Z1 General] Untouchab1e:
Just wanted to pitch in here. I went to a store and compared the Xperia Z1 to the Xperia ZU and they are certainly not using the same display panel. ZU has better contrast and much better viewing angles while the Z1 washed out the moment you tilted the device. The guy at the store was headed to a meeting with Sony and was gonna ask them for clarification and get back to me.

While I think the Z1 is a nice device, the poor display is a deal-breaker for me.
[Xperia Z1 General] jos_031:
ZU contrast is worst compared to Z1. but viewing angle ZU rocks....
[Xperia Z1 General] ruchirtrehan:
You guys probably have to learn, I am tired reading those stupid bull****s of why Sony uses cheap panels not AMOLED and bla bla bla, first of all, Sony is not using cheap panels what soever, if you want Sony to give you AMOLED and IPS, you have to sacrifice water and dust resistance on z1 simply b'coz AMOLED and IPS cant be water proof if those are used on z1, secondly, yellow hue and different panels, are truth, some different panels are being used is retail models and by a mistake they have been sent into different batches and are being sold, you can always get a replacement, and viewing angles? they're not bad ofc cant win Htc One or Samsung s4, Note III in any aspect but viewing angles are perfect keeping it upto privacy, also you can keep the phone on dock while driving car for gps display doesn't gets washed out neither while using it to watch videos on bed or anything, if you feel viewing angles ridiculously suck you have a faulty display in z1, also camera is great (not to compare to 1020 it has a huge sensor) noise is there, that's all software related waiting 1-2 months will fix that, also to mention, go look at 1020 and s4 zoom, they're specifically camera phone, but what they look like is very known they look ugly from back coz of those cameras (in my opinion) whereas they z1 holds such an elegant camera taking no space backside, also this phone will have 4k video support, without any doubt, it will have it officially with future firmware updates and I can assure that. Also some people have reported yellow hue issue is due to firmware after upgrading to .534 so it might be also fixed with future updates and please for a sake, stop comparing it to others it's just useless to do so, please stop with that shi*, every phone comes with it's pro and cons there's no perfect phone and can never be, just saying use AMOLED in Sony is a waste, have you ever dare to say use a Ferrari headlight or any other feature in any other car? that's simply stupidity of yourself to ask such crap, and stop watching/reading those freaking reviews and pics which are up their over the internet, in this whole universe no camera can show you what exactly the display looks like and it can never capture it, so just stop yelling around and go to a Sony showroom and check it yourself!
[Xperia Z1 General] bucho2004:
Erm, I have a z1 and I like it, but there are ways sony could have improved on the z1. I might not be affected so much by the viewing angles but it would have been better if they used the ips screen like on the z ultra, that's water resistant too by the way, just so they can avoid troll comments and and the bad publicity that whether we agree or not, it is still getting, that sony screens are less superior compared to competition.
[Xperia Z1 General] ruchirtrehan:
You have mistaken yourself, Z Ultra does not comes with a *IPS* screen, viewing angles are actually great on it compared to z1, but head to head or even holding in landscape mode, z1 has a better display with a better contrast. Have you seen the Galaxy S4 Active? It's also waterproof and does not comes with AMOLED or IPS screen, I am sure this should be enough to tell you why so.
[Xperia Z1 General] bucho2004:
I am very sure z ultra does have ips screen. Yes straight on the z1 screen is brighter and seems more impressive head on at full brightness I actually posted this too somewhere on here.
[Xperia Z1 General] jos_031:
every panel have its on advantages and disadvantages... waterproofing have nothing to do with panel type. zxu uses eips display. the panel used in xperia z1 is good. with 20% angle you can see 10% loss in gamma. and 45% angle 50% gamma loss. this is how the panel tech used work... there is no scientific way any one can justifies other way. but display is good in Z1. there was noise in almost all sony phone cam and if you see all where talking about the magic firmware that will fix the noise, but it never arrived.
[Xperia Z1 General] Ame123:
I am having prblm with the pinch to zoom gesture..its very jerky and some time dosnt happens at all can u check??
[Xperia Z1 General] jos_031:
There is no issue in pinch to zoom.. it works smoothly,,,
[Xperia Z1 General] hoezay:
In this video review by Phonedog, http://youtu.be/jPIdn4TUWQ8 I notice that the phone displays whites perfectly, and doesn't seem to go yellowish or creamy, neither are the viewing angles very bad. My Z1 looks nothing like this and has the yellowish or creamy white tint happening towards the lower half of the phone.

(or maybe i'm going blind and/or mad)
[Xperia Z1 General] Jiyeon90:
Just got the z1, the display is good viewing angles are ok, not the worst, not the best.. oh and my screen show whites perfectly, I never noticed that my Acro S actually had a warmer/yellowish display until I compared them two side by side.

Sadly I'm returning my z1 because it has 5 dead pixels, hopefully they will wanna give me another one.

Overall this phone is a beautiful beast, it never lags and the design is great.

Also my S/N starts with CB512 for anyone wondering
[Xperia Z1 General] nehway0912:
Seems like lots of people are still confused about the screen on the Z Ultra. All three models (Z, Z1, ZU) use VA screens, none of those are IPS.
[Xperia Z1 General] jos_031:
ZU is E-ips.. one person at marketing had told... and no one cares... if someone prefer viewing angle over high contrast and sRGB color accuracy he should not buy Z1... someone who can bear with viewing angle gamma loss for good contrast and color accuracy buy Z1...it is plain simple...buy what you like.. dont let others be your judge...some people dont care about plastic body. some do care.. some hate sony design.. some loves it...buy what you like... go to a showroom... see it yourself... decide it yourself... dont let others dictate your decision...Of course we can help everyone with the doubts. but finally it is your phone not ours..our preferences and perception will be different from yours.every one is different and special on their own way...
[Xperia Z1 General] sg1969:
Looks like I got a dodgy screen as well. Whites are yellow, blacks are brown, viewing angle is very bad. Also got a couple SOD (screen suddenly blacks out, have to reboot)

I went to O2 shop (where I got the phone) and tried to show them, but those idiots couldn't see the problem. Showed them my device next to their demo unit which had no yellow hue, screen looked really nice with bright whites, and a more blueish hue, and STILL they couldn't see the difference...

So went to another O2 shop where they have a "guru" desk and the guy saw the problem immediately, he couldn't believe that 2 people could not spot it because it is so obvious.

Going back today to try to get it swapped, hopefully they have more "good" devices in stock
