screen discrepancies amongst three epics

so i have three epics in front of me, all on stock roms, all with brightness as low as possible, BandB brightness control widget shows all of them at 9% which is the lowest i can set them too, two have a yellow tinge to their whites, whereas mine is pure white... theirs appear to be dimmer and at max brightness its tough to distinguish any variances... im not sure if i should be happy or sad that their lower brightness would appear to give them better battery life

Mine is yellowish. Disappointingly-so,

Mine is pure white, on all low and all high.

Mines has the slight yellowtint

There seems to be some variance in screen color temperature. I was at the sprint store a few weeks ago and the display Epics all had cooler color temperatures and my phone was warmer.

The power savings mode settings changes the screen color on mine from a whiteish color to a greyish color. Also, my epic has an EXTREME blue tint when you are looking at it at any angle other than straight on. I have looked at a dozen other epic 4gs and none even approach how blue mine gets when looked at sideways.

I've also got 2 Epics, one with a yellowish tint which looks dull compared to the other at the low settings.
I noticed that between the lowest setting and going just slightly up a notch, the yellowish one has a lot of brightness difference, while the white one has very little difference in brightness.
Did anyone notice a difference in battery life? My white screen one is stuck at DG17 and the yellowish one is on DI18, so I don't think I can do a fair comparison.
I'm still within my 30 days, so I'm not sure whether to trade the yellowish one for a new one or stick with it..

Screen TOO bright as bedside clock

I had gotten so spoiled to how dark I could get the diplay on my Captivate when I used it with the Bedside app. Last night I changed every setting I could find and it still is VERY bright with a totally black display.. I could get the Captivate black screen Much darker. I did get the LED Hacks app to turn off the backlit buttons, but the black part of the clock screen will not get dark.
Does anyone know how to increase the "blackness" of the black?

I use an app called "Screen Filter".

There is a button that looks like a jagged sun on the left hand side of the screen in bedside and if you tap that it lowers the brightness. it's VERY dim but totally viewable in the dark.

I think you are thinking of the clock for the Better Alarm app. Bedside doesn't have the sun toggle button. Thanks though.
I downloaded the Screen filter and will try that tonight. Thanks

I'm in the same boat with my inspire. Black levels in a lcd screen will never compared to the ones of a super amoled. If you want the darkest blackest blacks stay with your captivate. I heard they're getting froyo tomorrow.

It's called a super amoled screen, which the atrix doesn't have. Sadly, contrast on lcd screens sucks.

Sreen brightness and reflectiveness.

Hey, to those who already have the galaxy s4 can you confirm with me if its noticeably brighter than the galaxy s3? I know it's 258 lux in comparison to 213lux on the galaxy s3 but in real world use does it help a bit with sunlight legibility? Also is the screen less reflective than the s3?

Yes and yes. I wouldn't call it the best phone to use in direct sunlight but it has improved quite a bit from the S3

Screen:
- Brightness: Oh well, the maximum manual brightness is not as bright as my Note 2 (A Brighter Note app activated), but outdoor visibility is way better. Under sun light with auto brightness, white is whiter (brighter), black under s much less blueish - mean darker. I can feel better in reflectiveness also. I think most reviewers forget to turn automatic brightness on.

According to DisplayMate, on autobrightness it gets extra 30% brighter than on manual max.

Hey. Last night I noticed my SGS4 has a very reddish tint to an all black screen, compared to my SGS2 which is truly black (no light emitted).
During the day it is not noticeable but in pitch black you can see a strange dark red glow in black areas.
Anyone else experienced this?

Take a picture of it. If the screen is faulty, better replace it.

I'll try to make a picture later tonight. With the naked eye it was easy to see...

My issue: the red subpixels stay on, this is the SGS4 and SGS2 viewing the same 100% black image.

If any black background has visible red tinting to it you should definitely contact Samsung or the store.

Sorry that I sold my phone already (check my thread), but I did try to do it but it's not as noticeable as seeing in the real life, or my cam is not enough for capturing the screen correctly

To see the red blacks you have to be in a very dark room. Mine has it too.
The only thing I dont like about the screen is that Samsung seems to have omitted the antireflective/oleophobic coating around the menu and back buttons, making fingerprints on the buttons stand out

Pink screen at low brightness

I'm hearing a lot of different stories regarding the screen turning heavily pink when the brightness is at its lowest.
Thought i'd make a poll to see how many people are affected, then we can hopefully gather its its a hardware defect.

No pink here, even using an app that takes it lower than stock.

I'd say it's more purple than pink but yes I have it. Same thing when I had a Galaxy S4. I'm pretty sure they're using the same AMOLED tech, which is a shame but yeah.

Make sure to actually vote guys, would help out a bunch

I have had two 6's and sent the first back because of the pink issue. 2nd phone is still pink below 1/3 brightness slider, just not as pink as the first. Called Google and talked with a hardware tech and they said it was part of the performance of the screen, and just to keep it above 1/3 brightness (wack). Both phones I had only turned pink with adaptive brightness on and the slider below 1/3 in a dark room. In normal lighting it doesn't seem to dim into the "pink" range.

Same. I use adaptive brightness. My grays have a pinkish hue at very low brightness settings. Doesn't bother me, don't usually have brightness so low.
Just part of being an early adopter, I suppose. Not that big a deal to me, but I can see how others might be upset. It's my first phone of this caliber so I'm still totally stoked with it.

pink
My device turns pink with adaptive on in a dark room. Also without adaptive only when the screen is just about to turn off.

Mine does this of course, because it is something that happens with every AMOLED phone I can think of. It was something I forgot about of course being on a phone with a regular LCD screen for the last year, but as soon as I got my Nexus 6 I remembered about this little quirk of AMOLED. Hopefully custom kernels can minimize how much we notice it with custom color calibration.
Mine is also much more purple than pink, if it is actually a really pink color them maybe something is wrong, IDK. My purple tint doesnt start to happen till I am about 25% of the way down the brightness slider. All the way down and the screen is very heavily tinted purple. But that is too dark to see with anyway so I never turn things down low enough to make things look bad enough that I would actually care about. The screen look beautiful in any normal lighting conditions. I just think of it as a "night time feature" to be easier on tired eyes. lol.

Wasn't this talked about before release? I thought it was part of the brightness setting and to make it more of a battery saver?
N6

On... So if I jack my brightness down, it gets a little pink. Whoopty-do... Why care? It looks fine at whatever brightness I use and I've never expected a display to look perfect when it's almost off. It's not some damning evidence that the thing is low rent.
Everyone's looking to complain. Omg, If I click on back 19 times while shaking the phone and switching back and forth into chrome, I drop a frame.... A $650 shouldn't do that!
Smh

Oh I'm not looking to complain at all, I just wanted to see if it's something everyone had or not.
I've just heard so much Conflicting info on this it's driving g me nuts... Either way, I'm super excited about getting it ?

You should, it's a great phone. But like every other phone out there, there will be some that have issues and others that are just here to stir the pot.

Heck, I thought it was a feature to make it easier to read text with the brightness super low...
*shrug*
Well, I guess if it's a bug I am glad I got a bad one. Sure as heck not sending it back with the PVS 13. With my luck I'd end up with a 2.

My 2014 Moto X screen turns pink when I crank the brightness down also on lollipop. I think it's due to the AMOLED screen because I can do the same to my N7 and it doesn't turn pink. I've noticed on lollipop that the screen can be made a lot dimmer than on kk

This is all due to amoled folks. And partly how it is calibrated. But it is an inherent quality in these display panels. As long as it's not pink at your "normal" viewing brightness then :thumbup:

Sorry my screen is pretty:good:

One thing I have noticed is that with adaptive brightness on...if I turn my brightness all the way down I do see tint pinkish hue. If I turn my adaptive brightness off and turn my brightness all the way down...I don't have a pinkish tint on the screen.
Anyone else's screen reacts this way?

I've been reading about this issue all over. Maybe I lucked out but I don't have the pink issue at all.

Yeah mine does. Lol I am now learning that adaptive is not the same as auto-brightness. But seems like with adaptive on it keeps the screen a bit darker than without. I noticed with the slider maxed out or turned all the way down it gets much brighter and dimmer respectively with it off.

If you turn adaptive on, and manually turn the brightness all the way down (something you would likely never do in real word use) you will see it. Even in a dark room I don't see it since my display is still bright enough to stay over the threshold where this phenomenon manifests. If I go lower the brightness way down however, it appears.

yellow screen?

Is this normal or do I have a faulty unit?
Screen looks very yellow compared to my other phones.

What is the other phone? Go to settings -> display -> color mode and set color to normal, that will normalize it a little. It's set on vibrant by default. Regardless of that setting though, the screen on this phone is a "warm" one compared to others. The phone on the left is "cold" and bluish in comparison. Warm screens are a little more yellow/red, cold are blue. If the other phone is AMOLED there's your reason, but even if it's LCD, it's just tuned a bit differently. You should know that the phone on the left isn't producing a perfect white either, just a kind of white you're used to. Personally I prefer a warm screen, I find colder screens harder on my eyes.
TLDR- it's working as intended.

Unless you screwed with some settings no that isn't normal. If my whites were that yellow I'd return it. While an LCD might never be as white or black as an amoled it shouldn't look like 20 year old yellow paper either. WIth LCDs if you lower the brightness the screen will become more colored but nothing like that. You can also go compare it to some phones at the store that have LCD's and get an idea if its out of whack.

I spoke to two different support people at motorola ...one said it was normal for this phone as the screen was optimized for gaming?? .....the other said it was not normal and I should return it.
I tried using the app 'screen adjuster' to boost the blue light and it did indeed make it look white rather than yellow so it seems to be a color temperature setting so I'm still not sure wether changing the phone would make any difference and I can't compare in stores because they don't have them yet.
p.s. the other phone is an LG G2 which is LCD

Mine seems to have a little yellow at low screen brightness but it doesn't seem as bad as in your photo. I probably would not have noticed if not for this thread. Is your screen brightness low? Mine gets more white as the brightness goes up.

If it bothers you you can go through the return process and see if another one is different. My phone looks pretty much the same next to my Galaxy Note n-7000. That's AMOLED, but AMOLED or not, screens can be bluish. For perspective, here's what white looks like for reference. Neither of the phones are producing white. One is bluish, one is yellowish. Do you notice it when you're not comparing phone screens? After a few minutes of looking at the screen, going from app to app or looking at pictures, do white things register as white?
