Weird Screen Issue

So here is the basic situation:
My friend and me bought a same i9000 from the same company at almost the same time. It's Telenor-Hungary.
We have been using it for over a year and I discovered an issue with the screens just yesterday.
I'll provide some screenshots:

"lightbox_toggle_sidebar": "Toggle sidebar"
}
as you see the only difference in the two screenshots is that I use 182 dpi and he uses 240.
But when we look at the phones with our eyes its not the same.
Mine , the lover dpi one is faded and greenish its blue is not really pure.
we tried to take photos of the difference:
so you can see the left one is more greenish and it's like missing some light blue or something i cant define. The best way to say it his phone has deeper colors.
also we discovered another difference
this is the 240 dpi (right one) with the better colors
and thiis is mine the sh*t greenish colored
you can notice the sim tray and the micro sd tray is different colored.
any idea why my screen is different than his?
By the way we use the same rom/kernel : teamhacksung b14 and devils latest with led2
thank you please just take a loook

Oled screens get worn out after time, especially the blue color is going to wear out fast. It could be that one of you two uses his phone more intense than the other...

Thats true mate!
I use 20 times more than him

This has nothing to do with usage.
It's just a difference in ur hardware. many users here on xda have this problem including me.
My girlfriends phone has so nice and deep colours but my phone just looks yellowish and wasted.
I installed chainfire3D and use nightmode to adjust colours manually which brought a really nice result and I also use voodoo color for adjusting gamma values.
This brought me a whole new display and now it looks like this of my gf. Feel free and try it.
and to your sim tray and sd card problem^^
Your friend has the protection stickers/foils still on and u don't - that's it!
greetz

Thats the same colour the Sim Tray. Thats plastic...

Yes, you can think that's the amoled technology that gives a strange tint until you see different devices.
Then you will notice some screens are quite OK, some are yellow and some are blue (and right out of the box).
I don't know if Samsung had several screen batches (they do that on PC monitors and TV without warning) or if the amoled panel is just not regular at the end of its production process.
Supercurio tried to investigate on some Galaxy S II models, asked people to give their screen identification serial and which problem/tint they noticed. I don't know if he came on a conclusion.
Anyway, for now you have this gamma adjustment tool included in Team hacksung ICS, you'll also have a new "Voodoo screen tuning app" with profiles and advanced options soon (Supercurio announced he will release it after he has sorted out some payment/market issues).

How can u tell me then, why i can see a bright ribbon on white screen where my status bar normally is? 5his is deffinitely a wear symptom...

Yeah, there's no denying screens get old too. I was just explaining this tint problem in particular.

[Q] Is Banding Like This Normal for a Nexus 7?

I've read a few posts on XDA which mentions the visible banding in gradients. I find it's visible quite often, in the settings menu, in photos, in apps, videos etc. If this is normal then I'm shocked it hasn't been mentioned in any of the reviews I've. I would only expect to see a screen of this poor quality in a cheap brand.

If my Nexus looked like that I would be unhappy.

I have similar banding but not as pronounced probably because my brightness level is lower. I haven't really heard of a N7 that doesn't have this problem to be honest.

Mine has it but I only notice it on dark blank screens and I'm not on dark blank screens very often or for very long.

mine had it, like i was in the point of noticing it and posting about it, but meh...
i changed Theme and its not there, i think its just the low quality design of the notification background....

Seems to be down to a poor quality screen. I guess they had to make sacrifices somewhere to keep the cost down. Thanks for the link toidimaet, I read through it and there currently isn't a fix for stock 4.2.1. I could ask somewhere there if they would mind making one but it sounds like the next official update might also include a fix (if you can call it that) so I might as well wait.

I have the same issue, the only rom which i haven't this problem was PA so that means it isn't a hardware problem? I can't find RadientFix for SmoothRom.

not a screen issue
the N7 has an IPS display panel, which renders colors, well, too accurately. for gradients you can use strong jpeg compression, which is normally not visible on standard screens. the perfect screen also has disadvantages - most mediocre images look awfully.
by the way, all of the wallpapers that are coming out of the box are useless in my opinion for the same reason

Display/Video Issues

Anyone having any issues with the display on theirs? I'm coming from a Note 5 and I feel like the screen on the S7 Edge is worse. I really only notice it in games like Clash of Clans or Boom Beach. Even the quality on the loading screens looks much worse. Not sure if it's just mine or if there's something I'm doing wrong but it's driving me nuts. I don't know if I should reset to factory default and start over but I haven't done much to the phone and definitely nothing that should be affecting this. Has anyone else noticed this with theirs?

Downloaded clash just too test this. Everything looked crisp

Side by side with my s6 this is definitely an improvement. Especially at lower levels

I too am coming from a Note 5. Waiting on my order.. Would love more updates on this..

Cleared cache and it looks better but I still feel like the Note 5 looked better at least in CoC. The screen looks great otherwise.

I noticed the colors in CoC look much deeper and crisp. Almost to a point that it's distracting. I took a screenshot of the game and looked at it in the gallery and it looks more like the it does on all my other devices. I thought maybe game tools was doing something to it and turned that off. That didn't make a difference either. I'm sure there's something that's being done on the video processing level that's affecting the color.

And how about the color swift? The white turn into blue or green when you view in low angles?

It's just physics. There's going to be color shift with a curved screen. That being said I don't notice it.

Im not talking about the edge curves, I'm talking about the screen, I see the edge and note have a lot of this issues and not so much the s6 normal and s7 normal.

I noticed it too. It seems that if a game is detected, it changes the screen mode from basic to one of the more super saturated modes. I dug through the settings looking for a way to shut it off, but haven't found anything yet.

You put the phone in settings (white images) and if you see in a little angle you can see the whites turn in to green or blue, and I see it more in the edge variant than the normal. It's very annoying

I'm talking about this issues, I see a lot of videos in YouTube and the edge have this issues and the s7 normal won't. This is why some edge have a more visible edge curve with this color and other not so much. See the photo

Anyone facing gray text on note 4

Hello everyone,
I'm facing a problem (or may be i have ocd) but I see that black texts on white background on note 4 is not even black. Actually it's more black on the left and some kind of gray on the right of the screen. But not completely like that. Some center block of the screen also have the gray texts. And somehow some character has the gray top and bottom and center black. It's very weird to me. I think I will borrow a camera to capture the screen and post here tomorrow.
I came to the Samsung warranty center this after and they say my screen is perfectly normal although I can see the unevenness by using web browser and especially kindle. I use kindle a lot and didn't spot the problem because mostly I use low brightness and black theme. They tested r/g/b/w/black using *#1*# and I don't see the problem here. I also borrow another note 4 and a s7e and also see the problem but not bad as my phone.
Is this by design?I used many lcd-product (iphone, ipad) and never met this problem.

same here, the display on note 4 is far from perfect. I have owned many note 4s most of them had an inconsistent display quality across screen. But not all people notice it...

Do you think this is amoled flaws? I don't have any problem view pictures, watch videos, but only seeing gray texts. I will borrow a good camera and upload the screen photo here.

I will borrow a better camera. Just got these pictures from iphone 6s. http://imgur.com/a/7JxGf

yes the display panel on most note 4s is like this but most people don't even notice it. Its not really a problem...very minor stuff....i used to worry about such minor things as well and kept wasting money on swapping one phone after another but i have learnt my lesson...there is no such thing as a "perfect phone" ! so get over it and enjoy your phone :good:

I found my issue. It's because the screen gets dirt and my finger print and effect the text quality. I haven't even think that text quality can be affected by such minor things. I cleaned them out and found the texts great again. But I want to say that even the screen is clear, some texts are not black, but not bad as in the picture.

How is the screen uniformity on your S5E?

I have a wifi US S5E a couple weeks now. I like dark mode and use it wherever it's available. But as you know, dark mode doesn't necessarily mean black background but dark gray backgrounds, and one noticed some uniformity problems. So I finally pulled up a gray test pattern and yep it's pretty ugly
Here's the S5E (right) next to my 6 year old original first gen tab S, displaying this video. Brightness is set to around 33% on both.
https://youtu.be/Qi4Wy7vE8-o
Like all OLEDs the S isn't perfect, but you can see the S5E is worse, almost like a gradient, grey on one side, black on the other side. Also, while the S is grey like it's supposed to, the 5e has a purple tint to it. The tint is exaggerated somewhat by the camera, but it's there in real life too. I never notice anything amiss with the S display on regular content, but the 5e uniformity definitely sticks out from time to time, especially in the evening.
So I'm wondering, do I have particularly bad uniformity or is this par for the course? Kind of disappointing that my spanky new tablet has in some ways a worse display than one that's ready to croak.

I suffer from poor uniformity too. Maybe not as bad as in your case, but clearly visible. I read that the bigger OLED screen is, the higher probability of suche issue. I was thinking about sending it back to get refund or exchange, but since I bought it abroad, I finally gave up on the idea. And you know what? After few months I almost forgot about it ? It's possible to get used to it
