Question (problem) about display - LG Optimus 4X HD

Hi, I bought my 4X last couple of days.
Im very happy, but now I have one question about display.
I was surfing on the internet and I noticed that on top of the display, there is slightly brown or yellowish tint
Its visible on white or light grey background.
I noticed it isnt on LCD panel becasue when I look closer or in another angle the effect like disappeared.
It looks like sea-bow effect or glass reflection on gorilla glass or something similar but only with yellowish tint.
I red in reviews that the display is in some distance from glass, maybe there is slightly color distortion between glass and display?
My build is 1.1
Did you notice something similar on your 4X? Is it normal? Maybe Im too sensitive?
Thanks in advance.

So, I try to look at the display with white background in the dark room and I can definitely notice sea-bow or reflection on the glass. Its changing the position when I change the angles during the view on display. Anyone notice this? Would be very appreciated.

Yes, i seen to. But it's a very light effect. Is not a problem for me. If you don't advertise this to me I would not seen it.

Anyone other noticed this issue? Thanks.

To be honest, no. I tried to do in your way, I'm not blind, but I simply don't see nothing abnormal in mine Optimus 4X HD.

I have this problem too, and my Optimus 4x is 3 months old. Maybe it is cause by the overheat problem? Since the phone heat up mostly at the top part when playing games or browsing.

It could be that when the phone heats up, the glue melts and the screen gets "dirty" or its because of screen bleeding or because of pixels getting damaged because of the heat.
I also do notice it. Try to look at the phone at a very steep angle, I see that my screen has a blue tint on the bottom and a weird other tint on the upper side. I bought my phone on march 2013 Only noticable on white backgrounds.

backlight uniformity

I've had my N7 for a week and a half now, and there is only one flaw: I have a 1.5cm dark band down the right side of the screen. It's only really noticeable on white or solid pale colours, so for videos and games it's fine but it's a little distracting when reading black on white.
I have only the slightest amount of backlight bleeding round the edges, even under extreme conditions (ie. full brightness in dark room,) no dead pixels, no ghosting, no issue with washed out colour. So I'm just wondering if it's worth getting a return or just waiting to see if it evens out a bit.
I haven't found any mention of similar issues on the forum, so I'd like to ask how people are finding the uniformity of the display?
same problem
I have the same defect.
How did you resolve? Did you get a replacement?

I think I might have the same problem. But with mine it only shows after having the screen off for a while, and it slowly fades to normal after the screen warms up.
So far what I have done is have all dark themes so I dont see it anymore. Have tried to refit the cables inside and using pixel fixer apps, none had worked.

[Q] Uneven Red tint on the screen?

Anyone having issues with their screens?
I have a red tint near the top right corner.. the bottom left is more bright than the top... it appears like a gradient accross the screen... noticable on dark greys... What should I do? is it a defect or are all devices like this?
Help please. any inputs will be appreciated.
How low is your brightness and is it set to adaptive?

The brightness is set to full, adaptive is off. When set to full, the tint is low but noticable.. when set to 50% the tint becomes more prominent.. and I do not have a problem with the tint.. it is just that it is not uniform.. the top right is tinted while the rest of the display is not.. it is really disturbing when reading an email or typing in landscape.
I think color uniformity issues are quite common on this device. You see some threads on reddit and also here on xda about this issue, most people have some sort of yellow or red tint on parts of their displays. The display of my Nexus 6 is a bit more yellow to the lower right of the screen, however I really only notice it on higher brightness with darker colors in apps like Google Camera or the Material Dark keyboard theme. It used to bug me in the beginning, but I somehow got used to it. I don't see the need for an RMA and get a potentially worse device with other defects as mine is perfect otherwise.

I was thinking the same.. it doesnt bug me that much. but when it comes to keyboard on landscape and specially the google camera dark grey background.. i can clearly see it... otherwise my device is perfect. I read a lot of articles too.. the device is expensive and at such a price getting a flawed display is unacceptable. My main question is are all amoleds like this.. because I had a galaxy s3 and it had a perfect display with no tint. Are all nexus 6's suffering from this problem or is it just a defective batch that is affecting some people. ? My device is just 2-3 day old so I can get a replacement.... although I am hesitant to do so..

I know the feeling, when my device was just a few days old I freaked out like this too. It's hard to justify at this price point but the truth is, no device is perfect. I went through several N5's back in the day and none of them were perfect, most of them had a few dead pixels, creaking body or even dust particles in the camera.
If you say your device is perfect otherwise, won't you rather live with such a small and hard to notice defect than going through a cycle of potentially worse devices? If you ask me, don't go for a replacement. But in the end it's up to you.

Here my vendor is sending me a new device. A box packed one. It should arrive in 2-3 days. The tint on mine isn't noticable when the brightness is above 70% , but I cant use the phone continously at night at such high brightness. Besides the tint is so bugging me when reading anything.. browser, play books.. the uneven color temperature from top to bottom.. it is really annoying and considering that I have paid so much for this I wont settle for this. Lets see how the replacement is, I'll post when it arrives.
Got my replacement.
I got my replacement yesterday. THERE IS NO TINT. BUT. the display has a vertical band that is noticable at time. Well, I can put up with this atleast there is no uneven color anymore. I cannot describe how awesome it feels to use a flawless / near flawless display.

Pink hue tilting the screen

I noticed that tilting the screen if my S10+ make the white turn a little bit into pink... anyone else? It's really really barely noticeable. I have leaved on original screen protector and since to me for now is fitted perfectly on the screen, I don't want to take it off only to check that it's the cause of this kind of "rainbow effect ". Someone else could check it?
Sorry for my english...
Yeah, noticed the same. My S9+ don't have it. Also S9+ screen is is more white compared to S10
Have peeled screenprotector of but stays the same. Screens looks better though without protector.
My S9+ also have more "white" screen compared to this S10+, however screen shifted a little bit to blue/green if tilted...
I've noticed it as well on my S10e without the screen protector. Not that noticeable and not as bad as the Pixel 3 but once you see it, you can't un-see it
Could be wrong but OLED/AMOLED have this trait - not issue but rather if screen is tilted it will have a red/pink hue - same when I had a Mate 20 Pro and while the same its less noticeable on S10+ ( better panel maybe )
Blacks are spot on but whites aren't perfect.
So i think i will leave the screen protector on until i'll have to replace it...
I have this issue too, TMobile US. But only towards the bottom portion of the screen, the top part is fine. Which leads me to believe it's a defect in my particular case. It's very distracting. Also fingerprint sensor works whenever it feels like.
Have to return it now.

Mine is different, i notice this pink/purple hue only tilting the screen more than 30 deg in any direction, if i look at it straight, whites are perfect.
Mine is the opposite , I keep blue light filter on all the time and the Samsung screen gaurd
When tilt i get a greener tinge
Just looks normal, tilt any screen or look at it from oblique angle things look differently

Anyone else facing a light yellowish tint on LCD

Anyone else facing a light yellowish tint on LCD on Nokia 7 plus. It is nearly unnoticeable until you place it next to another phone and compare. Phones like Samsung have colour temperature setting for this.

Touch screen issue test / reproduction (video)

Hi All,
I also experience the touch screen issue on my Galaxy S20 FE.
I have created a short video on how to check and reproduce it: Galaxy S20FE touch screen issue - testing and reproducing
Please share your comments if you also experience it.
Did that experiment and i think my device is "ghost touch free".

Yes, if you don't experience this, you unit is issue-free. I have also asked others to test, they have no issue at all.
This is why I think that *might* be a hardware/production issue.

Yes, that's what it would seem to suggest - and it's discouraging, I was really hoping this was a software issue. Would the 120 Hz refresh be a factor in this? That is, do you get the same result at 60 Hz?

Nothing. Either under charging or not, either 60Hz or 120Hz, no matter if Touch Sensitivity is set to low or high, it happens.
But as it doesn't happen for everyone with the same software, it tends to be a hardware issue or a production defect.

Tested mine with no issues but I had a bit of red tint on the screen as I have posted in another thread.
I just checked mine and I have the same issue, would samsung rma for this?

Thanks for the feedback. It seems not all users are having this issue. If you cannot reproduce the issue following the video instructions, then you are touch error-free. But then, it shows that it is not a general issue, but some manufacturing defect. For the red tint, I have seen your other post, I also have a barely visible greenish one, around where the camera is, and around the bottom 1/3 mark. But as it was stated, it is somewhat "normal".

I notice it somewhat when looking directly at the screen but very visible off screen, when using a white screen though.

Good question. I spoke with Samsung Support and they wanted me to visit the Service Center. I told them that I will not spend that much time on it, this phone is too expensive for having this kind of support. I will just return it and ask for a refund, then wait 1-2 months if the problem is solved.
I was just thinking yesterday...
This phone has Gorilla Glass 3 on the display, which is a way different structure than current GG6 (or GG4). GG3 is much thicker and more acts like a glass (breaks easier). Since GG4, newer Gorilla Glasses are more flexible, thinner, and more durable, too.
What if Samsung has just put a thick glass on top of a modern digitizer (touch panel) which was designed for a different structure and much thinner glass layer, and this causes the touch problems?

I notice it under normal circumstances like browsing, while straight looking at it, when the page background is like pale yellow/orange. It is only a bit visible, but when you read text and scroll, it is disturbing that the greenish tint remains on the screen. But honestly, this is not that bad. On a white background, I don't even notice it.
When I look from a bottom angle and moving the phone's angle, the tint bars move as well.

where are you located? I was thinking about doing this too for my red tint issue. but sounds like a lot of trouble. I would agree that you definitely need a new phone

You mean are referring to the green tint correct? Are you saying that you have no reddish/pink tint at all on your phone?
I notice it very clearly when looking at it at angle or even normal position. And I can see it move when I move the phone to different positions.
the XDA review has the same issue actually (nothing on the touchscreen): https://www.xda-developers.com/samsung-galaxy-s20-fe-review/
"The viewing angles, though, are disappointing because the display still features visible angular color shifting to blue as well as a rainbow out interference effect at extreme angles. Newer Samsung OLED panels have eliminated the rainbow out interference effect, and also reduced off-axis color shifting by a significant amount. The Galaxy S20+’s viewing angles, for example, are much better because the color shifting is much lower. Strangely, even the cheaper Galaxy M51 (review) doesn’t feature the interference effect issue (that is likely caused by the polarizer)."

EU. I bought the phone in the official German Samsung webshop. If I would be out of the return period, I would of course take it to the Service Center even with the red tint, but this way, I will just return it.

True, I have no reddish tint, I have some greenish one When looking straight at the phone, it is around the opposite side of the camera, and about a thumb tall. But really, not that visible, I just see it because I know it is there
I read the quoted article. This can also easily happen because of Gorilla Glass 3, maybe it has different inner reflection that causes these bands.

That sounds reasonable...however, what about all the phones using GG5, 6, or above that have a tempered glass screen protector on them, which would certainly make the glass atop the digitizer much thicker, and that do NOT have any touch issues? It seems to me that the thickness of the glass...up to a reasonable measure that I do not know what it may be...is not the issue here because my S20 FE does not have the touch issues. But mine does always turn on in my pocket. So it seems as if the proximity sensor is faulty. I wonder if this "bug" is somehow related to the touch issues. Though they appear to be different problems...they are related to how the screen works. Clearly something is wrong and I am not sure that any of it can be fixed with software. SMH

You are right, I also thought of it, but not only the thickness, but also the material structure can cause problems like transferring more static electricity to the digitizer that cause ghost touches. And the glass screen protector is on top of the screen which is far enough in distance from the digitizer. I can also imagine that combining this digitizer with GG3 would require less manufacturing tolerance than they used, and that causes just too much defective units. Just guessing...
But as you also stated, problems are mostly with the screen and touch panel. Ghost touches, incorrect finger recognition causing jerks, pocket wakeup, reddish/greenish tint on the screen. And +1: not all users have this problem.
If this would be a software-related issue, all models would be affected more or less. If some units are fine, some are wrong, with the exact same software, then it should be a hardware-related problem. Question: do they used different brand of digitizers for different units, or there is just a huge ratio of defective units coming out of the factory because they had to put as many units on sale as they could because Pixel 5 and iPhone 12 has arrived and they wanted to catch a lot of customers? Just guessing, again...

If watching from bottom angle, I see the bands, but in straight view, I only see some greenish tint. It is not very disturbing for me. I mean, I have a LED TV, which has some of these typical IPS clouding effect on the screen edges. 99% of the time, it is not visible because the content is bright. But when watching a movie that has a night scene and there is no ambient light in the room, it is awful. But in general, I like the TV

Interesting, thank you for the response. I see the red tint straight on and at angles too, so maybe we have a similar issue but a different color?
I also have a LG OLED, which can look quite bad in some very dark scenes because of banding.

That might be the case! Different color, but the same tint / band.
