Screen contrast changes and kinda flickers sometimes? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

As the title says. I don't know anyway better way to describe it. Its noticeable when pulling up the keyboard ontop of a white background. Like when using Google Now. Anyone notice theirs doing the same? Its not bad or even impeding usability but if its not normal I still feel I should exchange for another new one while I still can. I have turned off dynamic screen mode and adapt display and every possible that could adjust the screen.

I see the keyboard flicker, but only on low brightness. Funny cause htc one owners have the same issue with their keyboard. When i had the htc one, I had a problem where the screen would flicker non stop on low brightness. Went through 4 handsets, all had it. I know the new Snapdragon has a dynamic contrast feature built in....im not sure if Samsungs screen options are fully disabling it or not. I just know dynamic contrast was much much more noticeable with the One

So my phone probably isn't defective then? Cause like I said its not bad or impeding usability but just didn't want my brand new S4 to be defective. Thank you so much for your response you helped me a lot! :thumbup:

Yeah, you should hold in to it. No need to exchange.

Weird pattern grid

I honestly dont know where to post this as is there are many galaxy s forms. Anyway
I see weird pattern or grid if i turn the brightness to the lowest and i have dark gray wallpaper. Anyway its more visible in some area on the screen more than others. Is this normal? what is it?
Sent from my GT-I9000 using XDA App
i have a fairly good idea the grid you are referring to
there have been posting of this before in the forum
some people have dismantled the phone and shown the pictures from the inside
in most units you shouldn't see it at all
if you do it was probably not manufactured well, you are not supposed to be able to see it.
I'll return it for an exchange.
Like i said its very hard to see. And its not like u can go to the store and turn off the lights to show him something he probably wont see

Yup, I see the same thing on mine (using voodoo lag fix on lowest brightness). I can also see it on my GF's galaxy and my coworkers galaxy as well, but very very faintly as they're not running voodoo so the lowest brightness is not very low
Most visible in dark gray. Doesn't really bother me that much as the screen is otherwise great
I sure hope we don't all have defective phones? I'm guessing it's an inherent issue in SAMOLED?

[Q] Screen Quality?

Hello all! I'm still using my Galaxy Nexus (Toro) and I'm due to upgrade next month, I'm now seriously considering the Galaxy S4, but the one thing that has me concerned is the screen quality.
As some of you may already know, the Galaxy Nexus has some odd color reproduction (especially in the greys) when the screen is anything below maximum brightness. It looks like there is almost a texture to the greys, and whites when scrolling. (See photos here)
I understand that this is the nature of the display on the GNex and I've learned to just tolerate it.
I really just want to know if the S4 suffers from the same issue at all?
Thanks in advance!

I personally notice the same thing for the greys in my S4, but I think is less evident than on the Nexus (my sister has one and I compared the 2 displays). In any case I think that it is a "feature" of AMOLED displays! The white instead is perfect and believe me is the best white I've ever seen on an AMOLED display!
Screen issues on the Galaxy S4? Where do I start!
*Pink tint
*Light Banding across the screen on low brightness
*Purple smearing
*Hue changing when keyboard is toggled
*Screen flickering when using data on white Web pages
*Purple greys on low brightness
I'm sure there's more!
The S4 is the worst of the Galaxy devices for quality control.
It was rushed to market to compete with HTC and Sony and so suffers a lot of issues.
Don't get me wrong, I love my S4 but definitely check the screen as soon as you get it.

Dont know about i9505 but the only "issue" i have on my i9500 is purple smearing that too on some 3rd party apps and barely noticable(after the update)...
And s4 has currently the best screen that u cn get in the market apart from iphone5 or note 2..but the latter phones are not full hd so s4 somewhat wins the round.

The latest update did NOT fix the smearing.
It is just no longer as noticeable in the settings of TW.
All 3rd party apps and even other parts of TW still have the purple smearing, even the stock gallery.
It is simply a drawback of the AMOLED display showing pure black by turning off the pixels.

It's not a drawback of AMOLED it's a draw back of this display turning off pixels to make black.
The S, S2 and S3 did not shut down pixels for blacks.
You get better battery life and purer blacks on the S4 but the downside is the smearing effect.

Your right...we have to live with it...the pixel are going from off to on when scrolling through black menus..thats why this happens. ..older galaxies never actually cut off...if wanna fix this you can use screen adjuster and slightly adjust the rgb, this will stop the smearing but also stop the pixels from turning off when displaying black

[Q] Touch Grid and Display adjustment

Short:
To any G2 owners, can you confirm whether or not the display has a visible touch grid of dots on the screen?
Also, can you adjust the color tone for the display in options anywhere?
---
Long:
Some reviewers say it has a dot grid, some haven't mentioned it, however the reviews saying it does I think might be using the trashy AT&T screen protectors which actually have this grid directly on them. So I am *hoping* it isn't baked into the factory glass/cover.
Also, does anyone know if you can adjust the color tone and make it over-saturated like a Samsung AMOLED screen? I've been using OLED-based displays for 5-6 years now (since the Zune HD) and I'm extremely partial to them. I wasn't a huge fan of the HTC's Super LCD 3 (I could see it flickering and blacks were washed out), and I have heard the G2 compared to its quality, but wanted feedback from someone who might have a more final end-user experience.
It does indeed have the grid...can be seen with the screen off in the sun light.
Ir does yes, just like the nexus 4. Having used it all day out in sunlight I can say its only visible when looking at the phone at a extreme angle in direct sunlight. The upside i guess is that it does feel like a very touch sensitive screen.

Yeah, will confirm, I went to att to check the phone out...wish I had the money to buy it outright...but it does have a touch grid...not noticeable at all though

Screen smearing on galaxy S5's as well

Well i just noticed the dreaded screen smearing/purple haze on my new note 3 when i had the brightness turned all the way down, so i decided to check my new S5 and guess what its there too!
FU samsung how can they not pick up on this???
Yes there are fixes but it shouldn't be happening in the first place if you want to test yours out download the pic below, set brightness to 0 and zoom in on the pic and you will notice pink/purple smearing between the black and grey colours when moving the pic around.
Hmm wonder why they made all the menu bars green? now you know.
Don't see any problem in mine.

You need to have the screen brightness all the way down and make sure your looking real closely.
Out of the S4, note 3 and the s5 Samsung has seemed to make it the less noticeable on the S5.
What you could be seeing is the after image of the screen. You're seeing pink shade because of the way RGB is showing the color grey. You're seeing smearing because you could be moving the image around quite fast and the display is not fast enough to trail your fingers.
I followed your instructions and could see nothing that you are speaking of.
I have also previously owned a Note 3 and did not experience any "purple smearing" either.
In my opinion you are grossly overreacting.

I started the "infamous" thread over a year ago http://forum.xda-developers.com/showthread.php?t=2252445
Despite some thinking it was a software issue, it's simply a hardware issue with the panel.
The smearing occurs due to the native refresh times of the panel when going from completely off to dark shades, I.e black to greys etc.
The reason it wasn't an issue on older amoled screens was that the pixels were not completely off when displaying black, which is why in a dark room you could see a glow to blacks and also the "infamous streaks and blobs".
On the newer samsung amoled screens black is completely black, the pixels are not illuminated.
Samsung are just using cheap panels.
I spent a lot of money on an oled samsung tv there was the same issue. Putting a film on like sin city would highlight it. I returned the tv.
^S5 is the latest, so it's definitely new. So, was it really the panel?

1. Plain stupid and don't know how to adjust their phones display to reproduce the smearing, example: "homer285 What application requires one to view a dark grey image at 0 brightness zoomed in at 100%?"
2. or in denial and don't want to believe their perfect s5's could have such a flaw.
Because all S5s and note 3s for that matter are all shipped with the same display hardware tech, and no you don't have some super special s5 that has different hardware from everyone else cause your awesome .
Now saying that there are fixes for the problem, one can use a screen colour adjuster to keep the "off black pixils" turned slightly on witch helps big time but kills ur battery dead.

Not black on whole screen, but you may see pure black parts when you watch videos that are not on HD scale. Also, around 95% of movies have at least one dark or low-light scene.

Most of us are neither of those two. Just because you experienced it, it doesn't mean that everyone has. Phones are not made in a single batch/production date. It's impossible to produce millions of S5 in a single day anyway. All products sold internationally have the so-called batch date/number to trace possible problems. My previous S3 have the black blotches when screen is dark and viewed under very low light, but my friend's has none. Now, my S5 doesn't have any screen problems.

Have fun with your "smearing" lol
I can confirm this too on my SM-G900F 16GB model... The Note 2 and S3 i owned didn't have this, but the S4 does and now the S5 also....
When having a black background (and lowered brightness) you'll notice it when swiping through the homescreen pages.
I don't know what causes this but i doubt it can't be fixed, yet Samsung continuous playing it their own way by ignoring the problem (the 'anti-smearing' update they once released was a joke)
This should only be a problem at night or in low light environments(typically when screen brightness is very low). I'm pretty sure it's a hardware limitation of Pentile AMOLED screens with the diamond sub pixel matrix, and thus affects all GS5's at low/very low brightness levels.
I've suggested this a couple of times on here, I'll say it again: 1.Change the screen mode to Cinema or Pro Photo.
2. (More importantly) Download Lux(free) and change the White Balance to Fluorescent. This slightly tints the blacks, and greatly reduces the smearing effect.

The S3 had a PenTile AMOLED screen and it wasn't affected by this. AFAIK it's due to the Diamond Pixel layout Samsung uses on the latter Galaxy series.

[PROBLEM] Nexus 6P Screen flickering ?!?!

Dear Friends,
In peripheral vision, I can see a the 6p screen flickering slightly. Mostly only noticeable on bright white and green screens on full brightness (without auto brightness adjustment)
Can you please do me a solid one and check it out on your device?
1. Turn Off brightness adjustment in Display settings
2. Set phone to full brightness
3. Load a completely white background (chrome browser starting page or any screen testing tool)
4. Hold the phone centrally close to your face and look at another object in the room while viewing the phone in your peripheral vision
5. Look back and forth at the object in the room and at the screen to see if you notice a slight flickering or restlessness in the screen
The flickering is very faint and hard to notice in peripheral vision but it is definitely there. I tired the same with an iphone 6plus and the iphone screen (my brothers Iphone, I'd never buy none) definitely has no flicker at all. It's very steady.
The screen is also not as bright as the iphone 6+ but I think that is well known.
I'd like to know if it is standard with all nexus 6p's and if it bothers you at all.... maybe I am just obsessing or maybe not and I need to RMA the device which is a huge pain in the ass.
Thanks!
Thomas
I do not have this issue at all. There are two possibilities, there is a defect with your device OR you are sensitive to the refreshing of the display. However, most modern displays have a refresh rate of 60Hz or higher (I assume the Nexus 6P and iPhone 6 are 60Hz, but I cannot find that info) so it's odd you haven't experienced this with other devices.
My best advice is for you to get your hands on a different Nexus 6P to see if you have the same problem. If you can't do that, I would suggest you try to see if you notice it in any other displays. Maybe go to a store and try it with a Samsung Galaxy S6/Note 5 as those have a similar AMOLED display, whereas the iPhone is LCD.
Thanks for your quick feedback. I am really surprised that noone has noticed this. I am looking at the device straight I don't notice it either it is only in peripheral vision that I can see it but even then it is very hard to catch. I think that indeed it must have something to do with the refresh rate of the screen.
Maybe other people can give it a try ? I have a gut feeling that it is an "issue" in all Nexus 6P devices but that most people don't notice it because it takes a very malicious mind to see it. Maybe it's because the device is brand new and the screen needs some time to "break in" or "adjust" ?
I just want to make sure that I don't have a defective device.
Thanks everyone

I have heard of that before, but you're seeing the issue on super high brightness. Perhaps try it on a lower brightness to see if it worsens.
PWM (Pulse Width Modulation) is used for making the display darker. For example, say that a phone has a 60Hz refresh rate, meaning all of the pixels update 60 times each second. To make the display dimmer, the pixels are on for a shorter period of time in between each refresh. For maximum brightness, the pixels are on for the entire time between each refresh. Thus, when the display is dimmer, some might notice flickering as the pixels turn on and off.
Billy, again, thanks for your response. I will give it a try.
The best way I can describe it is that the effect is extremely subtle; so much, that I don't notice it looking directly at the screen but it translates into a sort of "nervousness" of the screen in general because you are left with the feeling that the screen is constantly moving and not really 100% steady. I am not sure if it is something I can/will get used to over time but I am willing to give it a try for a few days.
I am also almost certain that I don't have a hypersensitivity of some sorts but rather that all Nexus 6P phones have this issue just that most of the people don't really notice it.
I'd love to hear from others about if they see it
It's normal, it's caused by PWM. I don't notice it much on my 6P,my Note 4 had it much worse. Some people are more aware of it than others and seem more succepatble to seeing it.

Thanks nice to hear that it is "normal" i was worried i had a defective unit
So you are saying if you really pay attention to it, you WILL notice some of it for ANY person, right?
I have a Galaxy S6 and I have not noticed it there. Does that mean that the S6 is not using PWM ?

I think the S6 uses it also but some phones seem worse than others. As I said, I can see my 6P a little but my Note 4 was worse, I could see the flicker all the time.
I just checked my S6 for the issue (side by side with the 6P) and I can say with confidence that the S6 does not have the issue AT ALL. The screen does not flicker in peripheral vision and as a result appears steadier and calmer in general.
If i hold a video camera over each screen I can see scan-lines moving diagonally upward in regular intervals/spacing which both phones, however the lines are stronger and more visible with the 6P Screen. Which in my humble option explain why I am noticing this effect. I am just not sure if something like that warrants the effort of returning or swapping out my 6P
It doesn't really bother me but knowing that maybe other 6P devices have it less makes me think because I shelled out 699€ for it....
What would you do?

It doesn't really bother me but knowing that maybe other 6P devices have it less makes me think because I shelled out 699€ for it....
What would you do?

Does it get worse on the 6P when you turn the brightness down? How about on the S6, if you turn the brightness down (which should exemplify the PWM issue) does it have the same effect as the 6P?

Thanks for asking. When I turn the brightness down on the 6P it gets better; the effect is not noticeable anymore when it's set on 50% brightness. As soon as I have it on 100% I can see it from the corner of my eyes when set on a white background.
The question is really if I can expect it to be different on another 6P or if all the 6P's have this level of subtle "flickering" if I may call it.
I suspect the latter... and from this point of view it doesn't make sense to swap it out. if you are able to notice it ever so slightly on your device then changes are that it is present on all devices and that the 6P just has it more than for example the Samsung S6 because on the sammy I can't notice it at all, even on full or low brightness for that matter.
As you've said , if it were a PWM issue, It would worsen with low brightness, correct? In my case it worsens with high brightness. So what really is it then?
Quick question... Under normal day-to-day usage, you look at your screen out of the corner of your eyes and have the brightness set at 100%?

You're asking the right questions here and the answer is no to both ?
However I hope your can understand my concern because in the beginning nothing is more important than having a flawless device to my very rigid mind.
Also im worries that the screen in general is not calm as compared to other models such as the s6. Basically that since the flicker is present I might still perceive it even when looking straight at the screen.
I decided to order another 6P to be able to compare the 2 and see if the issue persists on the new device. Depending on the outcome I will keep one or return both. The flickering is really evident and IMO unacceptable for a device with this pricetag.
I am not sure if this is the same thing, but see the flicker in the attached video. It's at 5th,10th and 15th seconds. But then I checked it on Galaxy S4 and see it there as well. I don't notice it in any other screen. May be NBA app is causing it.

that is indeed odd. I think the app is causing it
I am just surprised that noone else has noticed the flickering as i described above. It is quite evident when you hold the phone in front of your face and look at something in the room. I wish others would give me some feedback on it

I have been searching for someone, anyone, who has this issue as I do. Everything you said previously, I experience as well. I've had a 6p since November, and the flickering was there from day one. It's easy to notice at >50% brightness on white or greenish screens. Less so on red and blue. It's something I've gotten somewhat used to, but sometimes it really bugs me. Have you had any success with trying things?
I have recorded the screens of the 6p and 5x. The difference and flicker of the 6p is clear.
