SAMOLED+ Pixel Response Time and Touch Screen Discussion & My Review of These Parts.
Hey all, I wanted to start a thread to have a discussion about these two things that are my only disappointments in this phone.
Let me start by saying I think this phone is awesome, and yes I feel there are a few other faults on the phone (lockscreen delay when running off the battery due to the CPU taking a second to kick in, weak GPS/wifi signal sometimes, heavy banding on gradients etc) But those are software issues and I know in the near future Samsung/Devs will sort this out.
But I had some big complaints that aren't (still I hope not) software issues. Firstly;
- Response Time.
By this I mean when you buy a new monitor and the response time is listed as 4ms or whatever. This is the time the pixel takes to make a full change. A slow response time will cause ghosting. And that's exactly a issue that the Samsung Galaxy SII faces. Ghosting.
I've gone through 4 replacement SII's for various reasons, and on all of them they ghosted. So it's not just my phone. Samsung bizarrely states the response time is 0.001ms which would be there would be no ghosting at all. However there is, quite a bit actually, by my testing the screen is actually around 6-8ms.
I want to see if anyone else notices it. I know there's been a couple of threads on this but I want to see if the majority of people notice this. Here's how to test, go onto white page with black text on, and then scroll down the page at a moderate pace, not to fast not too slow, try it at different speeds as well just in case you don't get it right.
The easiest way I find to do this is use the inbuilt stock news app, load up any story and it'll give you a long white page with black text you can scroll through. As you may notice if you got a decent set of eyes on you, the text will leave a trail. Also known as ghosting. To me, I find this absolutely unacceptable on such high end device.
- Colour
Also, as it's been widely reported and has been noticeable on all my GSII's, the colour temperature is very 'cool', nowhere near the perfect 6500k. As a result, white's look very blue. This is fine and you hardly notice it on it's own, however when I'm using the device at my PC, which I use on a 32" IPS panel TV I professionally calibrated, the whites on the GSII look more blue than the ocean! Technically this is a software problem and can easily be sorted when custom roms come along but jeez, this is some bad stock colour calibration.
Also when you tilt the display, the viewing angles are generally very good, however tilting the display by pretty much any angle adds an extra blue tint to the screen on an already blueish screen.
I'm an absolutely screen quality perfectionist so these points really get to me. Especially considering this is such a high end device.
Overall I'd give the display a 6.5/10.
After the colour temperature has been sorted, I'll give it a 7.5/10.
If the ghosting can get minimized somehow even slightly through software on top of that, I'd give it an 8.5/10.
Secondly;
- Touch Screen
Now we all know about the movement deadzone/threshold on the touch screen which is massively annoying, but hopefully that'll get fixed in the near future. But What I'm going to complain about is the low sensitivity of the touch screen is the best way I can describe it.
On my HTC Desire, I can tap the screen ridiculously lightly and quick, and the device will register the input, absolutely no questions asked. Absolutely brilliant.
However on the GSII the sensitivity seems to be a lot lower, I can tap the screen lightly and quickly and the screen won't register the touch at all. This is pretty damn annoying as sometimes I just tap the screen lightly normally and I have to retap things. Not very often but still. I wish the device was as sensitive as the HTC Desire.
In it's current state I'd give the touch screen an 8/10.
If the movement deadzone and sensitivity got fixed, it'd be a 10/10.
Now I'm sure I had more to write about but I've forgotten now. I'll edit it into the post if I can think of the other things.
Now as I said, I think the GSII is a smashing phone, sure there are a lot of niggles at the minute, but I know they'll get sorted soon. Just the points I've outlined in this thread are things I'm scared won't get sorted. But you never know, I'm really hoping they can get sorted/do get sorted.
As I said I've had 4 Galaxy S2's all had the above issues, and I've used 2 other S2's from friends who also have these issues, so it's widespread, I'm just curious if people actually notice it.
I've added a poll to the thread regarding these issues. Please don't lie to yourself about this stuff, if you notice it, please answer honestly
I honestly hadnt noticed any of this stuff, i even watched a video of the deadzone and couldnt replicate it myself. I also think the touch response is fine you must have a very light finger/thumb!
The ghosting i hadnt noticed probly because i dont read text as im scrolling i tend to go a page at a time and the fact that im too taken back with the smoothness that pages do scroll.
The blue tint you guessed it i hadnt noticed but then again its not often i hold my phone up to specially tuned monitors.. Then again maybe theres a reason for it maybe it helps reduce glare in sunlight, then again maybe im talking aload of ****e!
no offence but you sound like you could moan for england! chill out and focus on the things it does do well and you may notice the negatives less
Personally....I think your nuts. This is the best screen ever on a phone. I have none of those issues, the touch screen perfectly responsive, my whites are white as white can be. You keep getting your phone from the same supplier and that leads me to be what the problem is. mine is perfect in every way. lucky me I guess

Haha I could moan for england ;P
Nah it's just I'm very picky when it comes to screens. And I definitely expect the best on such a high end device, unfortunately the SGSII falls abit short on this.
It's still a great device. Really wish I didn't notice this sort of stuff haha.

Best screen on a phone possibly. It's not the best screen ever though, it's good don't get me wrong, but not the best.
And I assure you, your device has everything that I outlined in my original post, it's just down to the user if they notice it or not. When I used my friends Galaxy SII's (who both got it from different places to me and each other) I asked them about this stuff and they had no idea what I was on about, so I thought my phone was faulty and I had a look at their GSII's and theirs have the same problems aswell, they just don't notice them. (They did after I pointed it out though muwhahah)
I must not have a sgs2. Maybe its because mine is from first batch but I have none of your listed issues. After 4 devices, it cant be samsungs fault.
Heh, guys every SGSII have these issues, I'm not arguing that, was merely checking to see how many people notice these issues (not many in the grand scheme of things apparently) there's quite a lot of reports of these problems so it's just down to the user

I guess I have horrible standards. No shadowning on my phone.
The ghosting and blue-ish colortemperature I noticed right from the start. But to be honest: I really dont care. At least the ghosting is nothing which stands out of the crowd... all of them have it ... HTC, LG, Apple. The only reason you don't notice it as much, is the lower contrast on the other displays.
As for the sensitivity: It's a little lower than with my htc hd2, BUT I'm actually glad it is. The sensitivity on the HTC phones is ridiculously high. You don't even have to touch the screen and you end up clicking something, which can be quite annoying sometimes. On the SGS2 I never had any missclicks, nor did I have any non-responsivenesses. Perfect setup for my taste.
I think all of the average joe out there probably doesn't care about all this minor issues. You must have the intention to find the fault of the phone in order to get what you want to find but do you think most of us would be doing this? Haha.. Tbh I don't really care as long as the phone does what I want without falling apart. lol..
Yeah I was a bit surprised by the ghosting, having seen the response time claims, but neither that nor the colour temp (on 'movie') have really bothered me so far.
What has irked me a bit is the image sharpness. On a site like m.engadget.com the coloured text on white background has a dark outline all around it, which to me looks horrible. Anyone else noticed that?
I think the ghosting issue is due to the low fresh rate of the touch screen.It's lower than 60HZ.
When you scroll the screen,the animation is not smooth enough,so you see the ghosting.
It's more of a visual persistence issue.
I remember when some choppy animation showed in CRT,I can see ghosting.
Never the less,when your finger leave the touch screen,let it scrolling itself,you can see the "ghosting" would be less noticible.
But you can still see it,that's because of 60HZ refresh rate of the Display.
I just wondering if there is any way to change the fresh rate of the touch screen.
What are you doing that's causing ghosting issues? There is a definite color temp issue but that's how every amoled screen has been so far. I would take a little bit of blue tint over the black color performance
The thing that causes the ghosting, as I said in my original post, it fast movement. The screens pixels can't change fast enough so things leave a trail.
As I said the best way so see this is to loadup a long page with a white background and black text and then scroll down at a moderate pace, fast but not so fast you eyes your eyes canty follow the line of text. If toy do it right and you've got a decent set of eyes you'll see that the text leaves a trail.

hi,
You are not the only *nut* i noticed that on my device the grey sux big time,... specially on rgb 100 100 100 have a look here: http://forum.xda-developers.com/showthread.php?t=1084543
My white is ok, but the grey goes magenta,
PLUS
if u go to 160 dpa u will see the effect better on greys and gradients which involves grays!

Yep, there's a lot disappointments with the screen on this phone. However as the poll is so far proving, majority of people don't care for quality as much as us. Only a few others care/notice about the things we're complaining about.

Thanks .. Thats the funniest **** i have read all day...
Theres nothing wrong with my sgs2 and ive owned Hero's Desire's Nexus One's and even an LG2X.. This phone is superb.. This dude does sound a bit anal..
Hey. I can definately notice ghosting on this screen if i purposely try to but as others have said, it doesn't bother me in the slightest. When watching films or playing games it's non-existant.
As for the whites, you yourself stated you can't really notice until you hold the device against your professionally calibrated screen. How are the blacks in comparison? Out of interest, how much was that screen/calibration.
I think the main problem with alot of peoples gripes is focusing on only the weaker aspects of the phone rather than the device as a whole. People want perfection which unfortunately doesn't exist in the world of electrical consumer tech.
now i see this horrible grey everywhere i cannot even look at my phone any more!
I hope that this issue would be enough to change my device!
Hey drm111, as you know I have those problems too.
Did you have them on all your 4phones?
1) As you know I have this topic in wich one screen had this blue ish coat on the screen, noticable from the angles you talk abouth. But the other one does not have it.
So maybe not everyone has that blue coating? Did you investigated that further?
2) As you also know there is this yellowish/darker 1/3 of the left screen, probably some don't notice it. You have to be in a dark room or in a light one really looking for it. You read abouth this huh?
But I you didn't post it here. Aren't you having this problem? And did you have it on al of your 4 phones?
3) Ghosting, yes i notice it to. No sharp text when scrolling,is that the ghosting too?
I have this first generation ipod touch, text stays sharp when scrolling. Should be the case here too.
4) Than you have the grey tints, wich turn pink. You can see it in the topic of nongrata23. But some phone don't have it it seems. Software or hardware?
We need to figure out what is 'normal' and what isn't. As I don't want to send my phone back if it is normal at this point for all the gs2 that are on the market.
Let me start by saying i used to work for a PC magazine and was among those who blew the whistle on the nVidia texture replacement fiasco surrounding the Geforce 5800. I can see a single texture out of place in a high FPS game, so my eye is VERY keen.
The colour of the SGS2 is slightly blue yes, but mine is no worse than the average LCD, including the Retina display.
Response time is seemingly slower than the previous AMOLED screens ive seen, but again is more than a match for the LCDs out there.
I would say samsung have made a trade off between the sub pixel density and other factors. It works for me just fine.
The 16bit thing is interesting. It looks to me like the screen isnt 16bit, but it is using 16bit at times. Thats a driver issue.
I've heard many people complain about the unresponsiveness of the screen and its yellow tint. How bad is the unresponsiveness for someone who has this phone? Does it bother you that much and slow your typing? Does the yellow tint bother you? I'm coming from the SGS2 and I'm interesting in buying the N4 but I hear so many bad things about it. Additionally, I heard there is a rattle in the phone? I read up on XDA on a poll thread but I think it's normal? What do you think? Is this phone better than the SGS3? (sorry to bring up this phone) and not considering the prices of both devices. I want to forget about the price and just focus on which one will not give me any noticeable problems
Thanks!
i can verify that its not too difficult to press lightly and not have a touch register. although i dont usually press very lightly, so it really depends on the individual. if you normally have a delicate touch you will notice it. personally it doesn't slow me down at all.

I wonder what you mean by 'light'. Are you happy you bought it? did you notice the yellow tint?
The yellow tint can only be seen from extreme angles and I'm doing perfectly fine with the screen sensitivity.

Thanks! I'd still like to hear a bit more from other people :3 By the way did you face any other issues with the n4? at all? hows the battery?
I don't think you will be disappointed by this phone coming from an S2. Most of the "issues" have been blown out of proportion. The rattle being the best example.
Yellow tint?
The screen is on the warmer side, or may have its gamma off, it's not a yellow tint. You would probably not know the difference unless you compare it side by side with something like an amoled display. Some people have mentioned a yellow tint when you look at it from the bottom left or upper right corners at an angle. This seems normal as it shows a blueish tint from the two other corners.
Rattle?
I checked mine, and to hear this rattle I have to shake the phone vigorously next to my ear and be in a completely quite room to be able to hear it, it doesn't rattle at all if you just grab or move the phone.
Screen sensitivity?
It is indeed less sensitive, for me it sometimes fails to register taps on the home button, but that's about it, it doesn't bother me that much. It depends on whether or not you're used to very light touches.
I don't have any of those issues. My response is excellent and my screen has no tint at all. In fact my N4 has none of the issues being complained about.
I think a lot of the perceived issues are overblown. Typical for a device launch. The few unhappy people post and the majority are happy and don't bother.
It seems you have more motivation to go on a board if you're having an issue than if you don't. I experienced the same thing with the gnex launch (again flawless phone) and nexus 7 launch (flawless tablet).
I don't think I'm just lucky, I just think you're more likely to find those with issues posting.

Thanks I think I'm becoming more persuaded towards the SGS3 because I love AMOLED and I'm just too worried about this phone in general.. I'm not sure what you mean by light touches though.. I usually handle my SGS2 with one hand so I kind of press densely but maybe it is not enough.. Is it hard enough, for instance, that if you press your thumb on your forearm, that your skin will bend down (not sure if thats a correct word) a bit? Or does it stay still? I would say my skin moves a bit following my thumb..
I've had neither issue but I've also had no heating issues either and people keep complaining about that too.
My screen isn't yellow-that seems like some isolated batch.
The only time my nexus 4 heated up was when I was downloading several apps, watching youtube on 3G and charging the phone all at the same time. It cooled down very quickly afterwards.
I have grown to prefer the 'touch error' of this screen, I came from an SGS2 which has a super-sensitive screen (it can be activated by hovering close to it), often a swipe or light touch would register as a single point touch and take me elsewhere in the phone, especially with one-handed use. Now, though, I actually have to press something to select it. Swipes don't register as single point touches, an errant finger in one hand use mostly won't register, which is brilliant IMHO. I prefer it.
Choosing between the N4 and SGS3 is the hardest thing in my life so far. Just kidding. I hate the SGS3's design and I think the N4 is the most sexy beautiful beast in the world. Anyway, thanks a lot of the replies guys but I have... a possibly last query.. What would you guys do if you had a change to pick again from both of those phones?

Then I don't think you will have a problem with screen sensitivity. The most compelling reasons to get this phone are the stock android experience, future upgrades availability, and its solid build, it feels great in your hand. You will have to weight those attributes versus your preference for amoled screens. I have a Samsung 7.7 tab which has one of the best amoled screens I've seen and great hardware, but the lack of support and SW upgrades sort of makes the Nexus 7 a better option.
My screen does not look yellow to me, but it can depend on what phone you just came from. To me the green in some apps is not as vibrant as it was on my HTC One S.
I have no issues.

Thanks guys.. again xD What do you guys recommend for me?
No yellow tint on my screen, however the screen sensitivity is slightly less responsive than the Galaxy S III, but should'nt be too much of an issue. I would recommend the Nexus 4 due to the price, pure android experience, and the first to get updates.
When speaking of touch sesitivity you need to keep in mind that you are talking about a capacitive screen. That means it senses the capacitive charge setup from your finger and the screen. This can be effected by your skin, oil/dirt on your skin/screen, moisture content and temprature of the air. For these reasons it is very difficult to accurately compare the opinion of your touch to someone else's opinion of their touch.

Battery life isn't as good as the GS2, nor is the speaker or build quality and there is no Micro SD slot or removable battery. What is also annoying is seeing my friends I noticed that black levels were more of a grey, I just cannot get used to non OLED screens any more. There isn't really any improvement over the GS2, the only thing you can say is specs but the Nexus 4 is hardly the king, it's lagging behind the competition even with it's superior hardware, purely because of build quality from LG.
I was excited for the Nexus 4 but unless you cannot afford a Smart Phone and the £280 price point is perfect for you then there is no reason to buy it. I'm just gonna get the GS4 on my upgrade next year.
I came from a Galaxy SIII , and I couldn't be any happier. My battery life is much better, the screen has no yellow hue to it that I can see, even at weird angles, the touch screen couldn't be any more sensitive in the opinion (its just as sensitive as my sgs3 was) , the rattle is there, but you have to have the ear piece right up against your ear to hear it at all, if not it barely audible. To me, this phone is the best Android device I've ever owned, and I've owned ALOT of them. One more thing, this is the best screen ive ever seen on a smartphone too. Text is extremely crisp, colors are true to life, and it is really bright!
I hope this, and everyone else's posts have calmed your concerns about the Nexus 4. To be honest , you be missing out on an amazing device if you chose not to get it because some people are overly dramatic .
I hope you get it

This Nexus 4 crap is really perplex.. I don't know if to buy it or not. The price doesn't matter right now, I just want a good smartphone with a lot of development teams and sexy design along with good specs. To be honest, I saw the SGS3 on a store and I used it and the screen is amazing but if i get like 1 inch close I can actually see pixels .-. And additionally, I HATE the design. But if there's no other better choice I'll get it. What do you guys recommend? forget about the price please.
Hi everyone.
I have not seen this mentioned in N4 forum, hence I decided to start a new thread.
After my much awaited N4 sitting at the local UPS depot for 3 days, I have finally received it.
I did anxiously unpack and start it as soon as I got home. To my surprise, I’ve noticed significant amount of ghosting, particularly evident when swiping a screen with clock widget on dark background. I did come in from the cold, and knowing how laggy displays are when cold, waited a few hours to try again. To my disappointment the ghosting effect was still there. It can be clearly seen when compared side by side against Galaxy Nexus performing the same task.
I’ve never heard of ghosting being a software defect. So presumably the fact my device is still at 4.2 (as opposed to 4.2.1) does not have anything to do with it.
Did anyone experience anything similar? Does it go away with display use?
Thank you,

I have no ghosting on my screen? It is only a 60Hz panel not a gaming monitor. But it is significantly better than my old AMOLED panel which had burn-in/ghosting

Thank you. Perhaps I have a defective unit. As I previously mentioned it seems to be substantial in comparison to the Galaxy Nexus SuperAMOLED HD. I realize this is not a TV screen. However I am a bit disappointed it is a step backwards in terms of display.
I read plenty than some people did not like the colors. I am perfectly fine with N4's color saturation. It is the ghosting trailing effect when scrolling up/down in settings menu that drives me nuts.
Chris Chavez from phandroid thought the same thing ...I think its a defective unit or you just have "special eyes"

I don't have any ghosting on my N4 either. Look into getting an RMA.

Mine has ghosting also...I was totally suprized..debating if its defective or just have the eyes to see it.
I'm contemplating returning the G3 but need to ask everyone who owns the model if your units suffer the same issue or if this is just an LCD issue in general. I'm comparing on white backgrounds this noise/textured pattern reminiscent to a digitizer somewhat that literally for me defeats the purpose of having a QHD screen since it's the only thing I notice. When looking at my S4 AMOLED there is no such issue, and I just checked out the HTC One M8 with its Super LCD 3 in store and it doesn't seem to have the issue. The Xperia Z2 does also have this effect as well. Can anyone comment on this, and tell me how does it not distract you if it is there since for me it is a deal breaker!
I see it too- I just assumed it was my screen protector though...
K
I just realized this. I don't think a replacement will help. Seems like a panel problem. Until LG acknowledges this and ships out a fresh batch, I think I'll hold off on a replacement.

I've seen this on every G3 so far that I've looked at. It's not the digitizer because you'd see that when the screen was off.
My AT&T variant doesn't have any visible digitizer pattern
i dont see it on mine either
Its very hard to see. It can be seen on a white or light grey background. It almost looks like pixelation. Hard to explain.

It's not a digitizer pattern, definitely has to do with the lcd. Just reminded me of a weak digitizer annoyance. You have to look for it though but once you notice it you'll never unsee it

Seems like a vague statement. With the incredibly powerful cameras and even microscopes that can be done to really see these screens in detail, where is a picture of this 'visible screen texture'?
I can put the display all the way up against my face and can not see any texture you speak of. Please help to explain or at least show what you're talking about

OK do you have your G3 rooted? Probably you've got G3 with JDI panel, why don't you try to find it out and vote in that thread http://forum.xda-developers.com/lg-g3/general/g3-display-manufacturer-t2824310 ? Sony has also such patterns because they also use their own JDI panels.
I think that someone here is "looking for hair in the egg"!
I have this problem as well. I actually thought it was a real problem and went to get a replacement about 4 times. After the fourth one, I gave up after noticing that a lot of the G3s have it. I looked at a lot of display models (best buy and att stores) and looked at a lot of G2s as well. At first I was really annoyed by it, but now I've gotten used to it
I can see it on mine in certain conditions, but most of the time it's not visible. Same with any other device I've had, really.
I think I see what you're talking about, I just don't know how to explain it. I can only see it on a bright white area, and I'm guessing it's a result with the panel and how high the resolution is. I don't mind seeing it though... I don't see it as a defect since others are reporting it. MUCH less of an issue (if one at all) compared to a yellow screen area or something. Comparing this display to 1080s which never did this isn't fair. The technology is too new and doesn't have anything to compare to.
Not everyone can be expected to see it or notice it, especially since near sightedness is going to vary amongst people. Uncorrected, I can see extreme detail on objects within a 1-2 feet, but I can't see any details past 20 (signs are unreadable, etc). When I am using corrected vision though, my near vision gets slightly worse and the effect is less pronounced.

Yep, I noticed this as well. However, it is mostly only visible when the screens shows only a single color. E.g., it's really visible if you use an app like Dead Pixel Test. Under normal conditions, I've only seen it a few times, which is fine with me. The real problem still is the oversharpening.
I have seen maybe about 30 different G3s now, all of them have it but with varying levels of visibility.
It's one of those issuses there is probobly no point worrying about. All G3's probobly have it, nothing we can do about it (at the minute). If it bothers certain people that much, get a different phone

Done and done! Switched to the M8 and the super LCD screen is fantastic, Crystal clear. Love the G3 and I'll miss it but once I noticed that issue it was basically game over for me.

I agree with others that it's only apparent in unique moments, typically where black text is on a light background. After a bit of thought, I've decided that certain apps are not able to display the high resolution that the G3 can produce...so dithering artifacting occurs.
Its not an issue. I have seen it on every single lg g3 and its only visible on high brightness with a white background. And it seems like some models show it more than others, but most are acceptable.
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 ?
Thanks

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?

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.
