I bought my N3 2 days ago and after an hour playing with it i noticed that when scrolling in the menu settings (with low brightness) the gray bars show a purple haze just like some SGS4 screens did. I searched the forum if this is a common issue, but so far i haven't seen noteworthy mentioning of it.
So my question to you N3 owners, can you guys reproduce this issue or is it just my handset?
Thanks in advance!
Loll i literally just made a thread about this 5 minutes ago. This really makes me angry. Is it anything we can do? Like exchange our devices or something? Im beginning to think this is just part of amoled technology since it still appearing everywhere even after this so called "software fix" for the GS4

Yup its there, you shouldnt be bothered by this. All the phones are affected. Although i can't quite explain why this never happened on my S1 and Note 2
I am having difficulties accepting such a flaw for a €750 costing phone. Did they manage to software fix this problem for the S4?
I see it too. My Note 2 didn't have this problem.
The issue is not present in Note 2 because it has different pixel layout. Note3 and SGS4 both have Pentile "Diamond" pixel layout--which allows for higher ppi.
The thing is that it is hard to notice unless in low brightness you were deliberately searching for it in certain screens.
If you can't live with it, sell the phone and buy one with an LCD panel (eg: HTC One, LG G2, Sony Z1 just to name a few).
SM-900T here (US T-Mobile), zero purple haze. In another thread there was a guy who exchanged his European GN3 4 times because he didn't like the screen. Now, some people might just be picky, but maybe the European GN3s have different panels than the American ones...
Bought 2x LG G2, one T-Mobile, one AT&T, different panel color temperature/brightness
I bought 2 LG G2's over the past 2 days. The first one was an AT&T certified refurb D800, the second one was a "new but without box" (factory film still attached) T-Mobile D801. They were purchased from two different cell phone shops.
I inspected each phone carefully in store at the time of purchase. Both phones were in flawless conditions. Not a single scratch anywhere.
However, upon returning home with the second phone, and placing them side to side for comparison, I noticed that the two phones' panel look significantly different. To eliminate the brightness slider differences, I put both at 100% brightness. Made sure all power saver related features were disabled. The AT&T (D800) version looks cooler (blue) and brighter, while the T-Mobile (D800) looks warmer and dimmer. I then tried adjusting the brightness sliders on each phone, trying to see if it can match the other at any given level, the result was negative. Those were two different-looking panels, period.
So I'm confused at this point. Could it be that one of these phones had its panel replaced by a non-OEM part? I assume the only way to tell would be to find yet a 3rd, real brand new phone from an official store for comparison?
Your advice would be greatly appreciated.
You could always go to an official at&t or t-mobile store check to see if they have it on display and compare or ask if you can view one, anyways I have the at&t one and I can agree that it is really bright, I have also already broken the screen and replaced it myself and did not notice any differences compared to original

Both phones are running the their stock JB rom. Haven't got to rooting/flashing yet. Can the AT&T and T-Mobile ROMs have different color temperature settings?
Well like I said I own the at&t variant so wouldn't really know I have not played with the T-Mobile one in person

Some time ago I bought 2 SGS+ from same shop/carrier. Both have similar s/n. Both have diffrent panel colors - same as you wrote, one is cooler (blueish) and other is warmer (dimmer). its normal, you dont have 100% that panels will be the same I had to decide which version is mine and which my wife and from then I didn't put them side-to-side and didnt saw difference
Thanks. That makes me feel better. But isn't the screen a major part of a phone that defines its characteristics/specs? I mean we see reviews about a phone's screen color etc all day, if it can vary this much phone to phone, makes me wonder what's the point of those reviews.
By the way, is there really such a thing as bad quality/fake/cheap replacement panels for a phone like the G2?

it's called panel lottery and all devices with the main component being screen suffer from it, especially tablets. too many things factor in this from quality control to bad factory calibration but the point is, exchange until you're fully satisfied with how the screen looks to you. my t-mo d801 has absolutely perfect whites and brightness, with a perfectly even screen.

I have the AT&T G2 and the screen is bright and does have a blue tint. I did not notice this until I bought a Nexus 5 and had them side by side. For me I prefer the bright but cool LG panel over the warmer but dimmer N5 panel. After playing for with the N5 for a week I returned it
Hey everybody. My 32GB Prime arrived yesterday and I'm a little underwhelmed by the screen quality. Compared to my little Jiayu G4S the screen doesn't look great, especially white. Thanks to lolo9393 I was able to read through the thread below and on about the second page there is info about how to discover who made your screen. Even though Xiaomi claimed the screen would be made by Sharp, it looks as though this is not the case for some of us. To test which version you have, open the dialer and enter *#*#6484#*#*. This will open a test app. Tap 'software version' then scroll down to where it says 'LCM'. It would appear mine is made by Tianma which explains a lot.
For those of you who haven't bought your phone yet, I would recommend asking your reseller to test your device first and see which LCD had been used. It sounds like AUO make a better looking panel (edit - or not?)
Here's how my Tianma screened Prime looks next to an Oppo Find 7a. Both are set to Max brightness. The Note 2 display is set to 'cool' in settings which is as blue as it gets. Any of the other settings make it look more yellow. The Oppo is on the left. To the naked eye the Oppo doesn't have the pink tint that you see in the photo.
*update* I thought I'd take another photo of my screen after two weeks and three different ROMs. Now I'm using the most recent multi language development ROM from 11th September. Same scenario as before, both screens are set to maz brightness, Opposed find 7a on the left. The XRN2 is set to 'cool' in settings and reading mode is off. Looks a little bit whiter than before to my eyes, but perhaps that's just wishful thinking. Either way my cheapo Jiayu G4S looks better than both. Shame the GPS doesn't work on the Jiayu!

Same here, me and a friend checked it, and both we have the Tianma screen. Both phones are 16GB version.

That's annoying. On the one hand, I guess it's common for manufacturers to use parts from different suppliers, but the phone has to only just been launched and Xiaomi made a point of bragging about using a Sharp screen. I think it's dishonest. I don't think I can return the phone to the reseller because it's not really their fault. My Jiayu G4S was just as cheap and has a much nicer screen.
Uhh. Does it really look that bad? I have ordered a Redmi Note 2. Hope that its screen is manufactured by Sharp.
For what I paid for this device, I think the Tianma screen (yes, I checked) on my device is fine. I think of this as an intermediary device as I dropped my old phone and needed one ASAP and in August this was the best thing on the market, for me it is a great intro to Xiaomi and I will wait to see what the Mi5 reviews are like when it is launched.
Do you have the TDD, FDD or GSM version?
Thank you!
Does anyone found a SHARP one, or they are all Tianma???

Yeah, I'm wondering about the same thing. Which versions have Tianma screen - all 16GB (not Prime) versions, or just the GSM version? Or is it completely random?
In a Russian video review a guy said that he had yellow tint with the GSM version, and that the display is better on LTE version (I don't remember which one was it though).

I have the 32GB Prime LTE version, and it has the Tianma screen. It's not awful, and considering the SoC I guess it's where they've saved money. If I hadn't just owned two Chinese cheap phones with better screens, I wouldn't have been any the wiser.
If I had a way to contact Xiaomi directly I would ask them to replace the phone, purely on principle.
One benefit of this screen is that it is softer on the eyes at night if you're reading in bed.
I might not be able to do it for a day or so, but when I get a chance I will try to take a photo of the difference between devices to show you.
Again, it's not terrible by any means, it just didn't meet my expectations.
Okay, thank you for your reply.
However, in this screenshot it looks like the other way around.
http://attach.bbs.miui.com/forum/201509/08/213030ox1sde17j41jcbd4.jpg.thumb.jpg
Tianma screen is blueish, but definitely looks better than AUO. Or could it be just about the Color Temperature setting in MIUI?
To my eyes the 'standard' setting looks creamy/yellow and the the 'warm' setting looks very pink/yellow. I set it to 'cool' immediately and it looks kind of OK, but it lacks 'pop'. I you were to put it next to a 2013 Nexus 7 it wouldn't look very good at all. Maybe tomorrow evening I'll try to mirror my screen to the TV and take a photo of the difference.
Viewing angles are good by the way. There is some 'crush' in videos and on the home screen wallpaper for me. I think it really will depend in what you're used to as to whether you like it or not.
This's the "old" news in China's forum, NONE of the screen is provided by SHARP
All the provider are from Tianma(85%)/AUO(15%) the number is the chance you will get.
There's also the rumor in China that Xiaomi never claimed they will use SHARP/AUO in screen, but actually, some of the people found that there's some evidences shows there's a slogan on their official site before selling.
And some of the people said Xiaomi break the rule in China's market with its super low price to force all the mobile manufacturer to lower their price. So some of the manufacturer edit the picture and spread the rumor that Xiaomi cheated consumers.
This is still a mystery because Xiaomi never apologize to this event but make good a loss
to the consumers a 5000 mAh power bank if you buying from their official recognized online shop, Tmall.com and JD.com.
I think Redmi Note 2 is released in the short time that the engineer in Xiaomi did't even tune it completely. The first or second wave who get the phone complaining the tint is too yellow compare to others. But if you are worry about the yellow tint, you can OTA to the latest stable version of MIUI or by FlashTool.
Don't forget MediaTek have the new technology, MiraVision™ which can easily tune the tint of screen color. By the latest stable ROM(6.7.5.0 Stable), Xiaomi also fix the unresponsive touchpannel by upgrading the driver of CTP from T2.0 to T2.3.
In short, you'll never get any screen from Sharp but mostly from Tianma and likely from AUO.
I have both LG G4 and N2 16gb, the Tianma screen isn't all that bad, although I see some slight bleeding that the bottom, but I can live with it, it is my seconardy/gaming phone afterall
I just got the phone. It has Tianma screen, but it looks good.
I'm pleased you like it I guess it just depends what screen each of us is used to. Sadly I've just come from a very 'white' looking screen (not sure if that makes sense).
I also just tweaked things manually using the Miravision app to get it more to my liking.
The screen on my phone looks very good, don't care who is the manufacturer of it, but i just checked and it is Thianma. I even compared it to calibrated with custom kernel Nexus 6, and still looked good.

That's interesting. I wonder if some are better than others. If not I must have really weird eyes, although the difference with the other phones in my household is very pronounced.
I checked and also got a tianma screen. It doesn't look too bad. I compared it to the xperia z2 (which has a pretty average screen though I think) and it wasn't really any worse. Maybe very slightly more faded at max brightness.
I'm more concerned about how much battery this thing uses. I've only had the phone for a few days but it hasn't seemed that great. Although the automatic brightness sometimes feels erratic and made the screen too bright.
Also I think I got some scratch already on mine. It's not visible if I wipe the screen clean so just need to do that and apply the screen protector that came with the phone. But I suppose no gorilla glass here!

Sorry to hear you have a scratch already I better hurry up and buy a screen protector for it. So far I only have a gel case to cover the back.
I'm not getting great battery life either, but I've only had a few battery cycles so far. Perhaps it will improve. My little Jiayu G4S also had a very good battery life which may mean my expectations are set quite high.
I'm not sure, but I think my screen may actually be getting whiter over time. Perhaps I'm just getting used to it!
my screen is scratched on day 2 as well in my pants too. Definitely not Gorilla glass.
Maybe it is just me (i think it is) but i'm not too impressed with the screen. Most reviews are stellar for the screen. when placing it next to my oneplus 2 i actually prefer the oneplus 2. I don't know whether I should RMA and see if a second one is any better or if it is just my mind playing tricks on me. One thing I'm really getting is the coolish hue when you tilt the phone up/down or left/right. I actually prefer my screens cooler. should I RMA or am i expecting something that is fine?
There's a difference in some of the screens, I had to get an rma because of the same issue. My new phone is perfect

What do you actually see then? Can you make a picture of your screen?

The Nexus 6P has a somewhat warm screen calibration which adheres closely to the target white point of the sRGB standard. The OnePlus 2 has a much cooler calibration. That's just the way it is and if you prefer cooler screens, you will like the OnePlus 2 screen better. That said, if you aren't looking at them side by side and just use the Nexus 6P for a few days, your eyes will start to get used to the warmer white point and it probably won't bother you anymore.
Manufacturers REALLY need to start including a white point / color temperature display setting. This is a setting you will find on nearly every desktop computer monitor, so I have no idea why phone manufacturers are too stupid to add this. I think HTC and OnePlus have actually added a setting for it in recent updates, but Samsung, LG, Motorola, and Google have yet to add the feature. Considering how long it took Google to finally give us a setting to toggle between accurate and vibrant colors, I expect it will take them a couple more years to give us a color temperature setting.
Hi guys,
Anyone else notice any uneven screen backlighting? I read forums on the v20, and when reading back text on white background - while scrolling down to read more text I notice dark shades on the screen. I downloaded screen test and lo and behold...dark patch on my screen! I then sent it back to LG and assured me that they replaced the screen module and tested it and all 'voltage' was normal - BUT, dark shades were still present albeit in a different spot!
Can someone here please confirm if this is a normal thing for LG screen as I realise it is LCD backlit and not OLED hence a few bleeding / inconsistency of backlight would be present. Even though I have never experienced this on ANY of my HTC's which were all LCD screens.
cheers guys! sorry for the long post!
Yes, i have it too! H910 variant. Two dark/dim spots that run horizontal from edge to edge. Can be more noticeable/annoying in landscape view than portrait actually.
Exchanged one brand new H910 for another. Same problem. Both manufactured 12/16. Havent had this on any other LG Ive owned (RS988 G5, D850 G3, P930 Nitro HD) or Moto for that matter. Pretty bummed to have this in an $830 USD device.
Edit...seems like the issue can be excaberated by different viewing angles. Also, totally anecdotal, but i looked at my display at a stoplight (wearing polarized shades) and i noticed the screen looked unaffected by the shades compared to other LCDs (cars TFT nav screen, an eIPS tablet, etc) that i have in the car. Wonder if what we are seeing is some type of side effect from a polarizing filter, or maybe lack of, used with this display/panel?
Or, maybe these things are edge-lit and LG used an uneven arrangement of emitters. Not really sure.
Good call...I do think it may be the backlight being edge lit! which could only mean (maybe) the backlight has failed at some spots or LG engineers mis-formulated where to put the lighting. it is very sad to hear that this may not be an isolated problem.
I did however sent it back for repair and the technician advice of a NEW LCD module/screen fitted. was sent back to me the same day!! WOW! BUT...same problem but it a different spot.
If this keeps going I may have to consider a new device altogether!
Then im starting to hear crackling on both earpiece and speakers....but thats a different thread!
arrgg...
I began to notice this on my v20 that I bought at the end of December, at first I thought it was just viewing angle or I messed up the screen. However my mom just got a v20 and hers' has the exact same problem in nearly the same spot. I should add that my phone is an LS997 that is completely stock. Also @D0NZ which screen test application did you use to see the problem better?
I used an app called full screen test...its free and simple. I then took a photo of it with my old htc m8 then sent it to lg for review.
The V10s have this as well. Something to do with the backlight and 2nd screen. Kind of got used to it on my V10. Was hoping that would have been addressed with the build of the V20.

I think so. On the V10 it was really noticeable when the main screen went into immersive mode and the 2nd screen went off.

this to me is a deal breaker! I read a lot on my phone, tis why I got a large screen! If this is the 'norm' for a flagship...
I pretty much think its unacceptable. They produce their own screens and cant get a flagship right? hmm...which phone to replace it with now that is available locally (for me that is down under)
So here are some pics I sent LG originally!

Looking at your grey screen, those bands/dim areas are in the exact same locations on my device (and my prior V20)! It must be inherent to this panel. You said the bands/dim locations changed after LG swapped screens/devices for you though?
Either way, it is a bummer. I'm still undecided if I should return mine as well, or just live with it. Almost every recent device has some quirk to live with it seems. I recently traded a Samsung Galaxy S7 that had a beautiful AMOLED display, but the device picked up scratches (on the display *and* body) like I've never seen before. I even took a look over at the dark side (Apple), and they seem to be catching flak for overheating and camera problems in some iPhone 7 devices. Sigh.
I have it on one corner pretty bad, is this because of the IPS screen and how the frame of the phone is pressing on it?

I think its to do with backlight distribution tbh. Ive had a number of HTC's and NONE of them had backlight distribution issues. Im now wondering IF a 3rd party screen module would be better than the original LG produced? OR...if this is an isolated issue only on some devices. My device was manufactured Nov 2016. Maybe a later produced model has better screens? Anyone with a newer produced V20 care to share?
I think its the placement of the 2nd screen backlight. Ill try to find the thread. Someone with a V10 explained it last year.

Here is the post I remember from the V10 forums that seem to make the most sense regarding backlight being uneven.
https://forum.xda-developers.com/showpost.php?p=64236798&postcount=45
Both my replacement V20 and original V20 have uneven screen backlighting (at least the replacement has a better back cover mechanism). There is a dark spot in the middle of the status bar on white (or lighter) screens. What is weirder is that it is the exact same pattern and location as the first one. It is present in both stock and LOS. I suppose I'll just wait around a year and warranty it out then because I just want to start using the phone. I included an image for people that were curious how it looked.
^
I think I can live with that...as in...the dim sections are on the edge of the screen. Mine was in the middle of the screen which i cannot stand!
I have sent the replaced screen NOT to LG but to the place where I bought it.
They said that the repairer that LG told me to send it to was the last on their system as 'reliable'. The store said that they will deal with the repairer and LG. I kind of hope the worst happens and they just offer me a refund or a total replacement - but I doubt that would happen!
UPDATE: so i sent it back to jb hifi, on the report, they can replicate the issue. On the repairers report - they couldnt
SO i get it back with all the 'test' that they have done on it being to manufacturer's specs.
Which i think now...was never good to begin with
Too bad i cant unsee what i can see...sux...I wonder if AMOLEDs have these issues? Anyone care to elaborate?

I have this issue with my LG V20 -- only when viewing photos - see photos -- screen has two long bright lines.
See attached photos - lines are not on the photos themselves --it is just in the backlighting -- and the lines are not there when viewing websites or if testing the screen with an test app. Please cut ans paste links to see photos - remove blank area after http -- I can't post links till I have 10 posts on this site - if any kind poster could repost so others can see them that would be great!

I have the same issue below secondary screen. Only noticeable on white background. Doesn't ruin reading books, it's there, but minor. I have dual sim variant. I'd be very upset if I paid launching price. All those things you only find out when you get the device.
