[Q] AMOLED grays - Prospective Buyer - Moto X Q&A

I am a prospective buyer of the Moto X and have my heart set on this phone. However, after using a friend's piece for a while today, I have concerns about the display.
I found the AMOLED display did not render the grays very nicely. They we very reddish brown in my opinion. I understand this is an AMOLED problem, but the X is supposed to have one of the best AMOLEDs out there.
Is this a problem generally in the X or was that perhaps a problem with that particular piece? Is this problem solvable via software?
Thanks!

It's most likely your friends piece.. No reddish brownish grey colors here.

so the grey's look grey? for example the news/forum/wiki bar near the top of this site? or the quoted text in this post?

Dude. I think I see what you're talking about. Comparing to my dad's note 3, his is more grey and mine looks brownish grey. I've never notice that..

I mean the greys are a bit harder to distinguish on his phone but I see the reddish brownish like greys on mine. *sad face*.. He's still jealous over my phone so I still win lol. The note 3 has a larger display and higher ppi so there are going to be differences.

Strange I don't see reddish brown s in mine , the shades of grey I find better than on my sons s4 active.

I've noticed that the greys gets brownish when the display is set to the lowest brightness

Browning and reddish, yep. It doesn't really bother me. My pictures look nice and i can't tell the difference from another screen. I think this is more noticeable in the system UI. Everything else is just fine.

Grey looks grey on my device. I've compared it to about 20 different devices I own (all with different display types) and I haven't noticed any different beyond greys being a tad darker on AMOLEDs, which isn't surprising.
The only time I found there to be an exception was when I set the brightness to 25% or less and held it up to my (far brighter) LED TV. There's an extremely subtle yellowish tint to it that I only see in this case. Immediately moving it away from my TV it looks perfectly fine again.
Long story short: You should be ok, and I wouldn't consider it a reason to not pick up the phone. Even if it were an issue, the device's pros far outweigh that minor detail. Plus you'd likely get used to it over time. Personally I think the screen looks incredible, better than on most other devices I've used.

Blueish screen?

I haven't received my Galaxy S yet but everytime I use my friend's I think the screen is just too blueish. Mostly the white parts. And I also think a "square field" is visible all over the screen. Is this because the resolution is too low compared to the size?
The phone itself is great so I still want it, but I'm afraid the screen will make me disapointed, especially since I've read so much about the Super AMOLED is so great.
Are all Galaxy S' screens like this?
What is the "square field"? please explain better.
And let's start from clearing the point of resolution/size-
800X480 is more than enough to go up to 7". If anything, it might be the pentile matrix that the screen uses.
I guess it's these "squares" I see: http://www.engadget.com/photos/iphone-4-vs-samsung-galaxy-s-display-face-off/#3115591
You're probably right that it's more the pentile matrix I notice more than lack of resolution.
I cant understand why many reviews says this screen is very good when it's very noticable.
I've seen mentions of different Galaxy S phones having different colour temperatures, though mine seems fairly cool.
PenTile does, unfortunately, make text less sharp, and there is a bit of a screen-door effect (I think that's the term you're looking for). It's a tradeoff for having a Super AMOLED screen - excellent contrast and very bright, but not as good as a TFT for text. I've become accustomed to it though, despite my misgivings (but a non-PenTile SAMOLED really would be the best screen without question).

What's the good side with PenTile? And yes, I've searched for "screen-door effect" and it seems as if that is what I'm seeing.
Yes, Galaxy S display seems to have quite high colour temperature. You can sort of calibrate it using the calibration app that was developed for Nexus One a while ago and is now part of CM6, but you have to run Froyo, install it manually and lose video overlay, so it's not really usable right now. Nevertheless I've managed to calibrate my SGS to more or less 6500K using it.

Not being able to play back videos and shoot pictures and videos Or, to be precise - you can do all of that, but all you see is white screen

Oh. Well, guess I'm not going with that solution then
But since it can be done through software, does it mean that Samsung could make an update and fix this?
I had this on my old galaxy S and coming from the x10's tft it was painfully obvious the white colour had a blue/green tint to it. I then got it replaced and the tint was still there but not so obvious. Now after a while the white colour looks perfect white. I think my eyes have adjusted or something.

Ok, guess I'll have to wait until I get my before I know how bad it is.
My friend got a blueish Galaxy S I9000. Mine isnt that much!! Next to his looks like mine is Redish, but mine next to my Monitor looks blueish! I believe some Screens have more blue tint than others
Mine is very white. Put the phone on a white screen (using a screen torch app) and the screen looks whiter than a piece of white paper.
Hey all, keep us updated if there's any application that can change the color temperature without affecting the functionality.
I got the phone a few days ago and my friend's is defenitly more blueish than mine. I dont notice the screen-door effect anymore so I'm very very happy with it.
Sent from my GT-I9000 using XDA App
I´ve read something on a German Mobile Phone Review Site (don´t know the which one it was now) and they said, that this is normal, because of the AMOLED Tecnology. They said that the Colors will loose the intensity over the years and as blue is the most energetic Color in the spectrum it looses faster the intensity. That is why it looks now maybe a little bit diferent. After a while it should normalise, because it was planned by the manufactures.
Ok found the Site. Heres the translation:
Higher blue components of the display of the Galaxy S may have been deliberately created by Samsung with the idea that the blue OLEDs are aging much faster than green or red. After months of use should mitigate this effect and color balance to be balanced.

They could do that if they wanted to, yes. But don't expect them to do so, I don't think colour temperature is of any importance to them if it stays within usable range.

Got this tip a while ago on some other thread - you can start Video player, play some video, go to Settings and change the Colour tone to Warm. It stays changed even when you leave the player. It's not perfect, but it helps a bit.

Actually, YES! Your eye do adjust to the white that you are looking at.
You've been doing this all of your life and haven't noticed it. The light in the morning is a very different color than the light at noon. In the morning, it is likely very red if the weather is good, and very white at noon... yet everything looks normal to you... because your eyes adapt to the color.
Adjusting to your screen is the same way. But compare it side by side with another screen and one or the other is going to look "wrong", usually the one you haven't been staring at all day!

Congratulations, your brain has created a special filter, using a process called "adaption", by the human vision scientists, that blocks the screen-door effect. You didn't know it, but your brain created one years ago that blocked out the 'striped-lawn' effect caused by the columns of RGB subpixels on conventional color displays. That 'striped-lawn' effect was just as visible the first time you saw one, but that was likely many years ago.
Okay so this blue tint thing is somewhat strange, still no clear answers.
Some people are saying "this is normal for super amoleds." I have to disagree. If this was normal, then every single Super Amoled would have this blue tint. I've put my samsung galaxy s vibrant side by side next to the samsung galaxy s epic, fascinate, captivate and other vibrants. Some have a blue tint, and others don't. Others have nice rich whites, while some like mine have a blue tint.
Makes no sense, so I'm not buying the "all super amoleds have this blue tint" statement. They don't all have them!
I've used my phone for over 2 months now, and the blue tint is not fading at all. Something else people said. I don't plan to keep this phone for 10 years, waiting for the blue to fade, I want nice white now, not blue whites.
Anyone have any updates on this blue tint some galaxy s phones show?

[Q] Yellowish screen?

Hi there,
The Galaxy Note is my first phone with a LED screen, I had a Desire HD before.
Since I got my Galaxy Note, the screen seems a bit yellowish to me.
When you tilt it a little bit to the side, you see the while colors becomes more white, but when you tilt it back, so the screen is right in front of you, then the white colors looks a bit yellowish again.
Is this normal for a LED screen?
I don't like the yellowish tint at all, but for the rest the screen looks amazing.
Thanks for your answers
Hmm I don't really notice any sort of yellow tint on my screen but then again I'm not the most color observant person . What you can try is go int settings==>display==>screen mode and change it from standard to dynamic or movie. I have it on dynamic and love it.

Yea I already tried dynamic mode, it makes the yellowish tint a little less, but it's still there.
You can notice it by yourself by tilting the phone.
Just put something on your screen that has a white color, and watch the screen from the side, it looks much nicer then.
Ohyea, by the way.
You can also notice the yellowish very good if you put the screen mode on movie
Just got my Galaxy Note N7000 today and noticed the same issue on mine. Tilting the screen slightly makes the whites look pure white while in its normal position the screen looks kinda yellow. I am not being able to understand if this is a faulty set or not
SAMOLED screens are supposed to have superior viewing angles, it is believed that the Oleophobic coating is causing the green/blue/yellow tinting that you see when the phone is tilted ( well in your case its a direct view ) my first screen had absolutely no color shift even at the most extreme angles, the new one I have now has a blue tint unless directly viewed.
The norm is supposed to have great viewing angles and only shift in really extreme and non usable angles.

Well, you don't have to be upset like that.
What I'm trying to say is that if you tilt the phone, it has great colors.
But when you look straight onto the screen, you see a yellowish screen.
Your conclusion is that the viewing angle are very good, and only shift in really extreme and non usable angles.
Looking straight onto the screen should not be a non usable angle.
And Im not the only one who's saying it, but when you tilt the phone, the colors looks much nicer.
Im not upset, I just found it amusing why it was not understood right off the bat.
Have your screen/phone replaced, thats clearly a quality control issue.

No problem, Keep us posted on whatever you decide.
I've had four blue Galaxy Notes and one white and they all exhibit varying degrees of tint with some less noticeable than others. Some have a more warmish yellow tint while others are cooler with more of a blue tint. It was the same way on the Galaxy S2. The best you can hope for in getting a replacement is one that has a tint that's less noticeable or if you prefer a cooler tint to the warmer tint.

The truth about the screen

Hi, i have tested my nexus and other of a friend.
The screen is the same, the only thing is that it seems that there are two different calibrations.
I opened display tester on both phones, and what a surprise, all the colors are exactly the same except the white, and grey.
My phone have warm white and my friend´s phone have cold whites, but the other colours look exactly the same.
So this is the only difference between the screens of some nexus, the white colour calibration.
Hope this clarifies the things

Unlikely, they'll all be made by LG Display. Probably come from different factories though.
Do all the screens have the off angle glow, especially diagonal? Both of the nexus 5's I have seen in person had it, but the nexus 7 2013 does not and has much better contrast as well.

Visible pixels

Just noticed that I can visibly see the LED pixels on the screen.. Anyone else have this happen after having the phone for a bit?
It's 493ppi so seeing 1 OLED pixel seems out there even for most people. I have 20/10 vision correct with contacts and I can't see them even if I try. Maybe if I had a dead pixel I could see it, but normally I can't see anything.

I didn't have that issue on my first Nexus 6 but I did have a camera issue. My second one is excellent no issues so far. I had my first one for 7 weeks before I had to RMA it.
I have perfect vision (my optometrist is jealous) and I can't resolve individual pixels on the display when held at "normal" distances.
After using the Nexus 6 though, I can resolve the pixels on my N7 LTE under certain conditions, after never having noticed it before. Drives me nuts.

Not corrected. I can see them also. It is mostly because of the uneven pentile pixel layout. Coming from an LG G3 which is stripe RGB you will definitely see a difference in quality. G3 is much more ordered and cleaner vs N6 a bit grainy with slight pink side. However, in my opinion it is an illusion because of a vertical vs diagonal layout. In both cases the blend is even.
My guess is that your new unit will not be any different.

My previous device was the G2 and in certain lights you can see the pixels with the screen off, especially outdoors. However, I don't see the pixel arrangement with the screen off on the N6; and I don't recall seeing the pixels prior to today.. Maybe it wasn't evident at first and maybe my eyes are now focused on the pixels, but I don't think you should be able to see RGB light reflections when viewing the phone display straight on. My HP laptop has the same affect when the screen has some wet spots; but the fact is, I can wipe dry those spots and the RGB reflections are gone. I don't have time to go to a brick and motor store to view the phones on display, and the new device should be in my hands mid-week.
Here's a thought - I installed the Skinomi Techskin a few days ago (probably a week now). Wondering if this screen protector is causing this?

So are you talking about seeing pixels when the screen is on or when the screen is off?
The die of the pixel arrangement will be visible under certain angle in just the right light when the screen is off.
Also, screen protectors can cause this to be amplified for sure. It all depends on the quality of that screen protector.
This characteristic is just one of those things you have to put up with when you're dealing with resolution cheating samsung crappy pentile amoled displays. I was hoping that the QHD would be enough to overcome the pentile, but that doesn't seem to be entirely the case for some.
At least (if tmo ever decides to actually ship it) it won't be as bad as my last cheating samsung amoled... a 4" 800x480.
I figured going into this, that the display would be pretty crappy. Too big, and amoled pentile... but after suffering with non-nexus devices for a few years (last one was a "nexus zero" -- ADP1...), I just don't feel like fighting with the thing, so fact of being a nexus > crappy display.

Screen Issue???

But to be honest, i am much more comfortable reading with some background light so i can at least distinguish something of my environment , and then this is a non issue.
For completeness i took a screenshot with my camera , and it's way worse then what i could see with the naked eye.
With the naked eye it is noticable , but not so bad as the camera makes to believe.
Anyway , a non issue for me.
And since my and your screenshot are suffering from the same hue shift , it might even be a problem with the moon+ reader.....

Thank you very much for following up. It happens in the gallery too. I've tried it with different pictures that have solid colours such blue, red, green, grey, etc. Do you think the warranty covers intentionally? I bought the phone with full of excitement while I was in Singapore for a holiday. I love this phone so much but the screen is bothering me. Sigh!

I'm pretty sure its not covered , the screen works flawless under normal conditions even in the the dark. Only when i go to extreme's like setting negative brightness levels in software the problem really shows up.
I will never have this problem unless i actively go and look for it.
same for me. the vertical and horizontal lines are not really an issue for me, i though i can live with it: i had the same on my p9 plus but on the left, there is a 2cm zone on all the height really darker and it made it almost unreadable at night (lowest light), even with screen filter or not.
i returned my phone and now i must wait to order a new one... my provider tell me they will not have twilight anymore.
i'm very disapointed.
Amoled screens are always a lottery when it comes to uniformity. Sometimes you have luck other times not. There are good screens out there and this time around I got one of the better ones. I have seen others complain about screen issues so not all screens are good like with most phones that have Amoled. Below is mine at 0% brightness and the app you used.
Mine has the issue as well. I ll be getting my device replaced soon as it also has a slight gap between frame and back panel at top left edge
Same issue here. First P20 Pro had it from bottom to top (pinky purple at the bottom, yellowy green at the top), second one has it left to right, but more pronounced on the bottom of the screen.
Is it worth replacing it again? I'm not happy with paying a significant amount per month for this if the screen is bad on all of them.
I would like to check mine. What is the best way to check this?
Update: So i opened lcd test app on my p20 pro and here's how mine looked like in the dark.
I don't know if i did it right but tell me if i need todo anything more to check this propertly.
Oh ffs, my third one has it too. Significantly green in the top left running about half way down the phone.
I've now been to the store 3 times, it's a 96 mile round trip! Nearly 300 miles of fuel wasted on this rubbish.
I get "it's a chinese phone," but we're paying Samsung prices for it, these screen issues are just unacceptable!
Have p20 pro for 2 weeks now. Always thought it's some dark theme design before found this topic. Have top much brighter than bottom in low light conditions. Can't see in bright room or in dark room with brightness more than 50%. I wouldn't be worried if it wasn't so annoying while I watching YouTube before go to sleep. Half of the screen grey, another near to black.

99% oled screens has this issue. Some are less visible, some more. But every oled screen phone I held had this issue.
Now I have Note 9 and dark grays are uneven too.

I have a Note 9 now too and while it's not perfect it's one of the most even oled screens I've had when it comes to uniformity.
