I love my Xperia Z4 Tablet. However the backlight is noticeably dim on the bottom (when in the default landscape position) or the left hand side when in portrait (volume/power button facing up). It is most noticeable in portrait mode when there is a white background (Kindle, Chrome and Instagram most notably). I am willing to live with this issue, but was wondering if anyone else is seeing any issues?
For the price I paid, it would be nice to have uniform backlighting. But I am worried it could be worse on another unit. Expansys has offered me an exchange or refund but there is a delay in availability now that the first lot has sold out.
No problems with mine
I am sending mine back for an exchange. I miss it already
Now I noticed that too. The difference is really small, but it's there.

Hopefully my replacement isn't any worse than the one I just sent back. It was as bad as I could handle.
Interesting, the same with my tablet - seems to be a general problem
I don't know if I should return and change the tablet...
can you make a picture for us? I dont know what you mean? my backlight is perfect - no bleeding and no clouding )
I'm sorry, but it was not possible to make a picture where you can see this.
However I can only see it on white backgrounds - the first centimeter is slightly grayish...

It is not a hardware problem. I see the band only when the bottom menu appears. It looks like the transperancy issue with that menu layer.
Mine looks fine, just hope it is not something my eyes just don't notice, but others do.

No, I think it is a hardware problem - if I turn the tablet from landscape to portrait mode, white backgrounds are gray on the left. Btw for me it's only visible in portrait mode - in landscape mode the menu bar on the bottom is usually black or transparent...
It is definitely a hardware problem and it sounds like the backlight is weaker on several units on the bottom (when in landscape) or left hand side (when in portrait with power button facing up). It is a shame as it is very distracting to read on anything that doesn't have a dark or black background in portrait. Still waiting for my replacement unit As long as the replacement isn't worse, I will likely live with it as I really enjoyed (and miss) the tablet.

Try anything with an all white background. If you open Chrome with no web pages loaded and the new tab page up or Kindle with a white background and hold the tablet in portrait, you might see uneven backlighting on your left or right sides depending on the orientation.
Backlight direction is notable
Got my Z4 tablet yesterday. After reading some issues with the backlight I checked this at my device and can see there is a notable uniformity.
If you hold the device with power button upside, then one can see a thin bright line from the backlight LEDs on the left side, while the opposite screen edge is slightly darker.
It looks like the screen is only backlighted from one side. For the normal usage it is not really annoying, but it is there and you would see it, if you take attention for the issue.
Do other Z4 owners have the same effect?

I have the impression my Amazon Z4T packages was already a replacement from someone else. The box made used look, some scratches and one corner had a ditch.
It wasn't sealed in any way. The charge adapter cable looked out of its the small box. The screen protection layer made the impression it was reattached, a lot of air bubbles were included.
Can someone describe how he found the delivery when unboxing it?
Was it sealed?
I also consider a replacement, if the screen issue is not a general construction feature.
Oddly enough, I purchased mine from another supplier, and also felt the item had been handled if not used. USB cable was out of wrapping and screen protector had signs of being removed and re-applied. I received mine the day after they were available for sale. I am hoping my replacement looks like new and has minimal or no backlight uniformity issues.

Hopefully you get it soon and can report here the condition of the replacement.
I have 14 days left to send it back to Amazon for free.
Please also describe how it was packaged.
Are there any seals or blister foil?
I can't believe Sony delivers an open package to retail stores.
Unboxing videos on Youtube don't show this clearly.
Thanks in advance.

For me:
Not sealed.
Box in perfect condition.
Screen protector had a few bubbles, but not that many.
It was perfectly even on the tablet, edges protector = edges tablet.
Charge cable was in box, but it was wound a bit loopsided. But I think it more likely that it came that way - besides, how many people do even need those cables nowadays? Even if they need them, they likely will not use them when trying the tablet out.
Charge of 65%
Tablet itself:
I couldn't see a backlight uniformity issue, tried it with a white background with 100% luminosity in a dark room. Compared to the Z1 Tablet the screen looks a LOT dimmer in the dark, but I suspect that is more because the Z4 has some auto-dim function there. In bright light the Z4 screen looks slightly brighter.
What I noticed is that the speakers produce a fair amount of white noise. At 10% it is very noticeable, at 50% I do not hear it unless it is a very silent scene and I am concentrating on it. Somewhat annoying and IMO not something a tablet in that price range should have, but not annoying enough for me to play replacement bingo.
My seller is out of stock with a new batch due next week. I'll let you know when it comes. From what I can tell, Sony products are never fully sealed.

Just got my N9 today from Best Buy. Have any of you noticed light bleed from the top of the screen?
Yep. From the top. Most noticeable with white.

I think every device has some light bleed from the top, so it's unfortunately by design. Mine also has a small brighter spot a the lower left bottom, but it doesn't bother me at all.

I should have made it clearer that I was talking about all Nexus 9 devices, not all devices.
Yup i have light bleed on mine also. Was thinking about exchanging but it appears that I'll most Lieut get another with bleed
I noticed some light bleed on the top edge in portrait mode. I didn't think anything of it at first but it really stands out in landscape mode.
Bleedgate?
I have some slight light bleed on the top of the screen in portrait mode. I'm not sure what to do...
My N7 2013 had light bleed also. Its not that bad unless you're looking for it.
The light bleed seems to be a manufacturing defect. Also, the flexibility when pressing on the middle of the back of the device seems like a design flaw. I wonder if Google will address these as known issues.
I took a couple of pics while running PixelTest.

And that's pretty much how mine looks like. There is noticeable light bleed especially around the status bar area (dark statusbar )
Yep. I got it too, but it isn't all that noticeable. There seems to be a large gap between glass and screen in general.
Yes, mine has the same light bleed at the top as well.
I got my black 32GB from the play store in UK. My screen is perfect. No light bleed at all. I've never had a tablet with no light bleed so this is the first. :good:
When I first turned the unit on, my first reaction was on my God!
Large light bleed, top left, top right, bottom left, bottom right!
I must admit it seems to have died down some what.
Contacted Google as soon as I turned the device on ?
They offered a full refund or to exchange my device, think I will wait for a few days and decide what to do!
Thing is there are no other tablets I like! See what Google is going to do, wonder if they will address these issues?
Light bleed, my nexus 7 2013 has it a bit, which then can only view when your starting up the device, but does it really impact the screen quality? no it doesn't.
White 32gb. I have horrible screen bleed on all corners and edges. I have never seen anything this bad. Another joke in build quality is the creaking back, every time I slightly move my hold on the tablet, the back creaks.
I might have been able to overlook these flaws if the Nexus 9 was priced cheap, but at £410, this build quality is just totally unacceptable. Its a joke.
I will be asking for RMA and if the replacement also has screen bleed, I will be requesting a refund and reconsider my desire to purchase the Nexus 9.
Light bleed on mine too... Top side only.

Did you buy from Play Store?
I bought my N9 32GB white from Amazon Warehouse on Feb. 17. It was the second I'd ordered. The first had a defect (bent frame). All has seemed well with this--very minimal light bleed; no dead pixels; recessed but clicky buttons; no squishy back--in fact, very solid. For the past two weeks, I've noticed a cloudy area about 1"x1" just below the horizontal midline near the center in portrait mode. It looks like a smudge but remains after I wipe. It's particularly noticeable as I scroll white-background screens. I even changed my Tapatalk app to dark mode to avoid it. I've tried to get a pic of it, but it doesn't show up well enough, if at all.
I came across a similar situation of someone seeing dark areas on light background on his LCD panel laptop after he had sat on it. It was reported that applying extreme pressure to an LCD screen could result in this phenomenon. I have not applied any pressure to the screen, but as it is an open-boxed item, it could have happened.
I need opinions from those who know about these things as I know nothing. ATM, I'm trying to train myself to scroll a page from the center so that my fingers hide the "shadow" which is also what it looks like.
Thanks

Hi, ritchea...
Sounds like you've not had the best of luck with the N9, this being your second one.
From your description it certainly sounds like a hardware defect with the screen. A manufacturing flaw perhaps, or something happened to the device whilst in transit or in storage at the warehouse
If it really bugs you, you should get it replaced.
I'm a little OCD about this kind of thing, and no matter how much you try to convince yourself it's nothing and to avoid looking (at the screen flaw)... subsequently, you spend all your time **thinking** about not looking... And eventually you look.. And wished you hadn't... if that makes sense. It detracts from your enjoyment of the device.
Rgrds,
Ged.
I'm a bit (more than a bit, really) OCD. I've owned over a dozen devices but never experienced this so I also assume a defect. I just needed to know if this is a possible defect that is known-especially when trying to get service.
EDIT: As this thread had had over 200 views, I'm throwing more info out there to see if anyone has any further insight.
I factory reset the tab --all stock except for relocking it. Darn if the spot didn;t seem to disappear. Then it returned. At that point, I decided to revisit the back. Hmmm. There is a little give in it--not spongy, but when I applied some pressure, I heard a sound in the middle of the tab like adhesive reattaching. (I've looked at the teardown and know that a lot of tape exists but not from the back cover to the rest of the tab.) I looked at the white screen, and again, the cloud was gone. In a few minutes, it reappeared. So, I firmly rubbed the mid-back and the cloud disappeared. I've now tried it over a dozen times (after restoring my nandroid), and applying firm pressure to the back always, but temporarily, removes the cloudy area. Can someone say what's most likely causing this? (I know it's faulty hardware, but I mean, what is happening to the screen when I apply pressure? Maybe a bubble in a layer somewhere?
Because of the camera, I don't want to get into taking the back off. I chatted with HTC to make sure my Amazon warehouse tablet was covered, and was told that it is even though (from the CSR) Amazon is not an official HTC retailer.
So, I picked up my new V10 today, and I noticed something odd. It appears that the upper left corner of secondary screen has a problem with the Backlight. Just wanted to see if anyone else is noticing this.
It's most noticeable when the second screen is running with the main screen off, especially when there are notifications coming across, the upper left side of the screen is over-lit. Please see the attached couple of pictures for example. (The first picture is hard to see, but you can see the brighter corner on the second picture where I have an email notification). It's also noticeable when the phone is in use and both screens are on.
I'm just wondering if others are seeing this or if it's possible that I got a small defect from factory.
The secondary display does 'bleed', as mentioned in a few youtube reviews. Mine also bleeds. Apparently this is normal but definitely not appealing.
Mine does as well. Only noticed it in my pitch dark bedroom last night.

It's not a defect, just part of using backlights. Look up LG G2x backlight bleed, that was a whole different ballgame, lol.
I'm only seeing that bleed in the dark until that screens dims a bit then the bit of bleed dissappears. I've never seen what you have in your picture.

Yours looks very excessive. In normal viewing conditions, the backlight should not ever be that noticeable. The only time I ever see the backlight on my V10 for the secondary display is in a completely dark room when the screen lights up a little bit because the phone was moved or something. But in this case, the backlight is leaking into half the screen because of how backlight bleed works in an LCD - i.e. it is not a hotspot like you have.
When I got my first V10, it had a hotspot in the upper left corner of the main part of the display. I noticed it immediately but wasn't sure if it was a defect or not. Compared it to the demo model and the salesman agreed, so we swapped it for another V10 right on the spot - no issue now, the screen looks beautiful and the secondary display and notification bar blend PERFECTLY into the bezel during use. It nearly looks AMOLED unless in complete darkness. I would swap your phone ASAP.
Mine does to in a dark room but once it dims the second time when screens off its hardly noticeable. Not what OP has though.
Nothing like that on mine either.
I did notice a very faint glow on the top right of mine but this is as others mentioned...Only barely visible and only in pitch darkness.
What you showed on the top left doesn't seem "normal" at all. +1 on swapping it out. I'd say that's excessive and a defect.

Thanks for the feedback everyone, it turns out that it was not normal. Just rolled back in from the T-Mobile store. Took it in, expecting to be met with some resistance when requesting a replacement. To my surprise, they immediately agreed and replaced it!
The replacement does not have this issue. Glad to get that taken care of, really my only major gripe so far is gone.
Glad to hear it! Happy endings are the best.
Sent from my LG-H901 using Tapatalk
Good to hear as well.
So there is no more light bleed on your second screen or it just isn't as pronounced as before?
I have some. The tiniest bit. In a dark room. Totally acceptable. I think this second screen is sexy as all hell
From reviews I knew there was a light leak issue. However, it does annoy me. I wish there was none at all our at least give us the ability to change the brightness. That being said, I initially thought the second screen would be dumb but now I can't imagine being without it. Switching between apps is so much easier now.
---------- Post added at 05:01 PM ---------- Previous post was at 04:19 PM ----------
Can you try pushing a notification to yourself, while the screen is off and snapping a picture like you did in your first post? I'm curious to see what it looks like because when my screen is off and I get a notification with a white background it's bright on the left corner just like your picture.
I have the same issue on white notifications. Annoying but considering first gen of this type of display...if in future models I'm sure they will have a higher quality one in future.

Went to the T-Mobile store to compare my phone to the display model. After playing with the phones I could see that my second screen display was in fact brighter on the left edge than the display model, so I'll be exchanging mine as well. Hopefully, I get a better one but at the moment I'll have to wait, since they are sold out. It was such a pain in the ass to get the sales associate to see the difference. Unfortunately, she couldn't but when she called someone else over they agreed that it was brighter.
I started a new thread about the dimming of the second screen(probably shouldnt have after reading here). Has anyone figured out how to make the display brighter again with the screen off? I can hardly see it in a lit room..
Thankfully the set I have (HK Dual Sim V10, H961N) has very very slight, almost unnoticeable bleed for the 2nd screen
I exchanged mine yesterday. That top left of BOTH screens was horrible. We went through 5 devices and every single one had some sort of bleed. I picked the one that had the least, and none on the main display. I'm sure LG will revise the HW and fix the issue but anytime you pick up a device with new tech expect some sort of issue.
Mine bleeds a little, but I really don't care.
Does any tablet owner here of M5 or same family tablet, has noticed if one of your display has an edge or sideline that is slightly slightly darker, during using a fully white background?
On my m5 Pro I've noticed that with a fully white backgroud, I do have an edge, close to the left bottom corner (holding the tablet horizontally) that is slightly gray rather than the right side. Off course that: if I'm rotating it, then it Will happear to the top instead.
If you don't stay there and looking at it for a minute, you don't notice it. But if you look at it and compare to the rest of the screen or other side, then you'll see this small difference.
Do you have same issue? Does it is an IPS display issue?
Ah! It makes it only with the White. Only the White. Other colors comparisions are fine.
Looking videos, pictures or anything else that does not push the screen to a very high density white in that side, it's fine.
You can try to see if you're having the same of opening the cleaning chache program, where there is a lot of White all around the screen. There you can watch side by side and every corner... and you can try too see if somewhere do you have a slightly white difference compared to the rest.
But as said above. Only white make this.
Videos, pictures with same colors side to side are fine. It's all about the White.
I've contacted the Huawei assistance trough Phone and they said that is normal and panels might do this, and if in doubt, I'm free to go to the Local official technical assistance in my town to have a confirm for it .
So I've done that! I've moved to the Local technical assistance and the technician told me that it might happens and it is not worthy of a repair, because changing panel might not solve the problem as this slightly slightly brightning difference might show on another side. Has more sense to wait if in these 2 years something going worse and repair it over warranty.
It's hard to see this difference of White brightness, and I've noticed that just because I'm a really fussy guy and ... off course I don't spend my time on surfing on the menus. It's also a post to understand it these kind of IPS panels may encount these issues.
Anyone here is experiencing this thing? Or are you watching all the sides of your tablet to see if do you have it aswell? :laugh:
It's called uneven brightness, and reading notebookcheck's review said that it is above average. Seems you have received a dud, but it's likely within tolerance im afraid.

Are you sure It's a dud? In a FB group a guy said that he's even worse on his 8.4 because he has it all over the edges . And on a previous M3 he got, there was an even worse side with less brightness. And so He returned the tablet.
In my case, it's so soft that you don't notice it at all. You do have to search for it. And it happens only with the White.
It the technician in the store told me it's not worth a replace the panel, this slightly brightness might happpen and same issue might happen in another side, nobody knows. I wish to beleive him . Why He would had lied to me?
Anyway I've read the m5 review and they are showing the characteristic of the brightness all over the display. Yea, it is seems a trait of it, and a 0,25 cd/m2 is barely perceivable.
What's your opinion?

You need something that can detect the brightness, usually expensive hardware that connects to a windows machine. I think they start at around $500 or so. You could rent one i suppose. (if you could find somewhere or someone!).
But yeah it needs hardware.

What did you decide? I have one side that is darker or M5 10.8, not a pro version.
Should I try to replace it? It does not bother me much and I read here that there are more units, that come with more darker sides/edges.

What did you decide? I have one side that is darker or M5 10.8, not a pro version.

The problem for me it's just a little and not worth a change for defect.
Because a repairing stores told me that quite always somewhere that little little darker side happear. It's not guarranteed that with a replacement it would not happear elsewhere. It's happening only with the White. Normal use the tablet is fine.
It's an issue of the IPS display, expecially large displays. That's Why i love the AMOLED all the way.
Technician said it's not for a change/repair, exept if it is gonna go worse.
So I'll keep it. Does your problem is so noticeable?

It is, the whole left side is darker, so I contacted for replacement. Amazon was very helpful and the replacement is coming to me. Hope that unit will be be without darker sides.
Thanks for help.

Did you had this issues also with other colors? If you were watching a movie or working on a picture was noticeable?
For me it's only the White, but you do have to look for it. It's same issues that have low/mid ranged TVs.
Not worth a change or a repair. Because it can ne elsewhere.
Does it is the same for you?
Keep us updated.

Yes, there was also a problem with other brighter colors. It was noticable only when browsing, but that's mainly what I do with a tablet. After a while I started searching for that darker side in various apps/colors, instead of enjoying a tablet.
Today I got a replacement. The screen looks more or less fine on the sides/edges both with white and other colors.
my m5 pro 10.8 is perfectly in balance.
iv´e tested with a white fullscreen wallpaper on max. brightness. everything is ok.
also other colors are fine.
...
every M5 screen has it. I had 3 pieces, each one had a near the status bar (battery, hour) visible only at a sharp angle. If you do not see it, you look at it badly. I stayed with the first copy. These two still had dead pixels. This is the construction of ips.
yeah i have no issues on mine, full brightness and looking from sharp angles doesn't make much difference at all. Slight brightness changes maybe, but same happens to any screen.
Anyone else having this issue? When I switch to the dark mode it's obvious the black level from one corner to the other is not the same.
A black saturation test clearly shows the bottom row visible when the device is rotated one way and then not visible the other way.
Anyone else getting this? I'm going to ask for a replacement.
Jup i have the same

Damn, that's almost exactly the same.
I just got a full refund for mine as the shop I bought it from had no stock for a replacement. Another one on the way from another retailer, hoping the display is in better shape.
The quality control on these appears to be a bit crap.
OneUI uses dark grey on the Tab S and Note10... There are many, if not infinite variations of grey that approach black. I do art, so it's easy to notice that #000000 was substituted.
SD_black is black, OneUI simply has a dark mode. Also black cannot be uneven on OLED, because black refers to an off state.

You're just splitting hairs.
Black can appear uneven on defective OLED displays. If you use a black saturation or black clipping test you can clearly see with the tablet or phone rotated one way that the bottom row is barely visible (which is normal), but rotate it another way and suddenly they're all clearly visible, they're only visible because that part of display is defective.
I have OneUI on my phone as well, there is no visible banding and black/gray levels (whatever you want to call them) are uniform. If you're seeing any variation then you got a bad display and you should get it replaced.
Similar here. But mainly noticeable in very low brightness especially with night mode on
With which app do you test it?

Display tester, first match on the play store. Find the black saturation test
Or you can use something like the below, loads of similar tests available on the Play Store or online.

Replacement arrived today and it's even worse than the first one, instead of one corner it's right down the centre of the display.
Also found an easier way to highlight the issue, using the image tester select the burn in test and move all the sliders to the left, this should give you black. Then slowly move the green slider over, you'll notice some parts of the display become green when the rest remains black, at least up-to a certain point. Took the image below in good lighting.
The Amoled lottery. I had to go through many returns before I got a Tab S3 that didn't have unacceptable display uniformity and things don't seem to have improved a lot since then.
I guess that it's cheaper for Samsung to deal with the returns of customers who notice and care about this than simply having better quality control in the first place. Reviewers of course get cherry-picked samples so the quality of the display can be praised to high heaven.
Really makes me think twice about even considering upgrading though...
same here, You say they change it under warranty?

Is your display like that for every image with that gray scale? Or is it just elements of the UI settings, dialer, contacts etc when you have dark mode enabled?

I'm doing this through Amazon,
I did call Samsung support hoping to speak with someone and they basically just said take it to a Samsung store, I'd rather not waste time with that, they'll just pretend they've never seen the issue before and send me back to retalier for a replacement.

you can even see it on on xda black theme.
But since this is a common issue maybe manufacturing level, I rather leave it like this, because I do not want to end up with an even worse one.

hi
hours ago i found that when a blank tab is opened in samsung internet (i am using dark mode in system as well as the samsung browser) i could see the uneven black on the screen. i tried to rotate it but still the uneven black was there on the left and right hand sides in landscape mode, and on the top and bottom after i rotated it. so it should not be the ui or one ui problem
i remembered i have read this post so i revisit it and found many of you have the same problem. when i bought this tablet i have check via *#0*# to see how the black was and it's perfect. i also checked with *#0*# before replying to this post and the black was perfect too!
i am too wondering what could be the problem. i think it could be the dark mode which does not use true black (pixel off) in fact

Yeah, It's not the dark mode, this issue effects everything.
If it was just One UI I could ignore it, but sadly it's not. Essentially you have different parts of the display clipping at different black levels, even the sections that are relatively good still look patchy.
Samsung screwed us all but it's OK because it's not a popular product so nobody cares, prime example of how useless reviewers are as well because none of them picked up on it, cherry picked parts from Samsung probably.

tbh, i cant live with it IF it affects my daily usage... but so far, it's acceptable
i will try to fix that once i rooted this tablet, just a matter of time
