The color white...

Has anyone else noticed that the ET4G's screen isn't that great when it comes to the color white?
When compared to my Evo4G,
pictures and video - ET4G wins - main colors are "colors"
websites with white backgrounds, pdfs etc - Evo4G wins
To me it looks like the white just isn't as bright, kind of like how the Evo's black isn't as black as the ET4G's black... if that makes any sense.
Is it just my eyes or my device?
ps I love this thing, not trolling, just trying to figure out if this is just me

Par for the course on SAMOLED screens. On SAMOLED vs. LCD, blacks are better but whites are worse, generally speaking.

I only notice it with my brightness turned down. Looks better at dull brightness (of course)

That is kinda a thing, yes. Though I have seen some very abused (S)AMOLED(+) screens and a couple unlucky new ones where the white isn't white and just sucks. That's what you call a bad screen.
the "O" in SAMOLED+ stands for "organic" and over time these organics do degrade faster than your average LCD. They have a type of compensation built into the circuitry to accommodate for this, but, in the limited amount of time most people have a phone they shouldn't notice it...though there are also bad screens that deteriorate rapidly and some that even burn in.
So, yes, AMOLED technology isn't known for having the whitest whites but they should still be bright white, if not you may either have a bad screen or a fantastic eye....hope for a bad screen cuz you can replace that, but a very good eye for these things may drive you fncking crazy.

samoled screens are like that.... yellowish tint for whites but the blacks are BLACK.

Interesting, thanks for the replys everyone

Then something might be wrong. Slashdot is my homepage and I've been going there since...I can't even remember when, over 10 years...12?
Either way, I know that color scheme like the back of my hand. I see it in my sleep. It has been my homepage for 10 years now. I've seen it on everything from a smart phone to projected on the side of my neighbors white house....Slashdot should look normal.
I'd investigate further if I were you.

The whites are fine. I believe your eyes are playing tricks on you. The blacks being so deep give it somewhat a darker tint to the whites, but in truth, it's there.

The whites are good on the SAMOLED+ screens. Just because they a brighter on another screen doesn't mean anything. Personally, super strong white would bug my eyes after a while.

I have a 'Mel Gibson' type "Conspiracy Theory" about this whole issue....
I think that Samsung, though they use exactly the same sourcecode as all the other manufacturers, might simply insert a piece of code that inverts the colors that they want, at a certain time.
For example:
Every other phone on the planet has no problem producing a vibrant "white" color....
Every other phone on the planet has a REAL problem producing a vibrant "black" color.
Samsung basically 'flip-flops" this, and I wonder if it's not just a well-placed piece of "inversion" code....
The results would be incredible blacks, and so-so whites...
Does anyone understand what I'm getting at, and care to comment?
<<This space for rent>>

Sht I thought that I was only one on xda that has yellow tint problem.
Its not just our Epics,tmobile gs2 and nexus prime have same problem.
And no-they are not supposed to be like that!
I looked at epic touch at sprint store and their epic was cool temperature white not like mine which is straight yellowish-orange.
I bought mine on amazon and im on my second return.My second phone was litle better but still orange-yellow compared to one at sprint store or my old Epic 1.
To sum this up:
Whoever has yellow tint on their epic touch or other galaxy s2 variants-they have defective phone.And its gonna get worse because in amoled screens blue colors deteriorate quicker than reast,so if your phone is yellowish now it will be red in a year or two,lol.
Its better to get a phone with bluish tint because overtime it will go away,while yellow will only get worse.

yeah u guys arent kidding... The blacks on this screen are effin black. lol.

What's the contrast ratio of our phones? I did a search but all that was said is that "it's high", didn't give exact numbers.
That being said is there a color calibration app, much like one's for tv's & pc monitors, that can be used on our smartphones?

[Q] Screen Banding and Notification LED ##With solution to notification issue##

I got my Galaxy Nexus yesterday and I love it. There's just a couple of things bugging me and wanted to see if anyone else was having the same problems and of course if anyone knew of any solutions.
1- Screen. The resolution is fantastic but i've noticed some banding in flat colours. It's most noticeable in light and mid greys. There is a strip that runs up the middle of the screen that is noticeably lighter that the rest of the display. This goes away on high screen brightness but is really quite hard to ignore at other times.
2- Notification LED. Why is there no native support for customising this in ICS!? Either I've missed it or Google have missed a trick. I got it working with an app from the market but it only worked while the apple was running in the background, if I dismissed the apple from the new task switcher... No more custom notification lights.
Anybody else having these issues?

To get the most out of your multicoloured LED you can use the Lightflow app which is available free from the market, to get this working properly on the Galaxy Nexus enable "Run in Foreground" in the general settings menu.
Thanks to jabok for spotting this setting.

Sorry to bump but I'd really like the opinion of a few other Galaxy Nexus owners, especially about the screen.
I love this phone but I am considering taking it back because of the banding on the screen, it's not noticeable until there is a flat grey in an app and then it's quite visible as a lighter band up the centre of the screen.
Is this a fault or is it to be expected on sAMOLED screens? I've only had LCD before.

Does it look anything like this or something different? http://forum.xda-developers.com/showthread.php?t=1320942
Either way there are issues with SAMOLED+ screens, there are people with the Galaxy S II and Droid Razr with screen issues too.

as far as I know, it is a common trait with Super AMOLED screens - had the same issue with my Nexus S, and with my friend's phones that have Super AMOLED screens.
The banding disappears if you have the screen at a higher brightness, so it does seem to be an issue inherent with changing the brightness/colour temp of the screen.
Also, AMOLED screens are susceptible to screen burn, which is why if you leave the screen on some white text on a black background, if you then switch to a screen with mostly grey elements you'll see a ghosted image of that text.

Seeing similar on my screen but it's not really noticeable unless the phone is on auto brightness or the lowest manual setting.
From reading other threads, sounds like the GSII has a similar problem. Looks like some people have been through a few phones before getting a "band free" unit.
You could try taking it back to a (willing) store for a swap - given the current stock levels you may have a few issues though and you may not get a unit without the banding anyway.
In terms of notification LED, wait a bit for some better third party apps to arrive. Not many (existing) phones use RGB coloured LED's or similar for notifications (Nexus One and Galaxy Nexus are the only two that quickly spring to mind) so it's possible Google didn't add support because of the limited use. ICS is in it's infancy and there's a lot of development to come (both from Google and third party dev's).

Thanks for your responses!
In some ways it's good to know it's a know issue, and in others it's a bit disappointing.

Personally, I'd just live with it - especially given that there's no guarantee you'd get a better model if you swapped it - hell you could end up with a worse screen!

I'm not sure it would be worth the hassle to send it back. This seems to be an issue to some degree in most SAMOLED screens. You might end up with a worse phone.
I seem to recall that many phone screens have artifacts at very low brightness settings.

This is exactly the same problem as I have. On low brightness it is visible but not on normal brightness.
I did have another nexus on order that I was going to compare it with but I decided to get an N9 instead as I don't need 2 nexus phones! I figure I can go try android beam in a phone shop lol
The question about sending it back is a tricky one - it's not visible With normal brightness so how can we be sure the replacement won't have the same problem? We can't.

yep. i have a vague banding when i look very closely.
solution ? keep my eyes more than 3 inches from the screen.
I hate it when people point out things that you have to look very hard at cos you then notice them forever more

can you confirm that with normal brigthness the problem is solved on every screen?

for the LED customisation get Light Flow from the market, works great for setting different colours for all sorts of things.

i just picked a random setting to prove/disprove the brightness thing. to be honest i REALLY have to look for these bands on auto-brightness .....
just tried 50% (still too bright in my opinion) and i still cant see banding. nor about 40%.
switched back to auto (which must be only about 20%) and they are there is i get really close and squint.
Seriously .... wouldnt let them worry you !

I have just completed a 3hr car trip using Google navigation and noticed the banding on auto resolution with it disappearing on bright vivid colours or dark/blacks. Thinking of asking phones4u to check out others for a possible swap.
When the phone was on charge i didn't notice any status light or none flashing when a txt was received. Should there be?

Pentile Display ?

it is said that the galaxy nexus uses the pentile display .. and all we know that pentile isn't really good .. so i am going to buy a nexus tonight and i would to ask you if the screen good or bad .. do you like it or not ?

I've had numerous phones, GS2, iPhone 4...this is the best screen I've seen yet.
The Pentile discussion is kind of ridiculous.

I've had four phones this year
- Vibrant
- My touch
- Nexus S
- Evo 3d
When compared to everything else including my friends' iPhone this is the best display I have ever used.

Its crazy good, by far the best screen on any device I've ever seen, blacks are so black u can't tell where the phone ends and the screen begins without looking really close. Also u can load up pretty much any page in portrait view with far away zoom and STILL read the really really fine text just fine.

Yeah it uses a pentile display much to people's dismay. Quite a few people/reviews have stated the following: 1.) Whites appear like a linen yellow. 2.) Blue tinge on the screen 3.) Pixelation is noticeable on text. While that is all true the screen isn't that bad, passable at least while playing games or watching videos. Is it the BEST screen ever? I would say no.

Calm down there Nexus fan boy/girl! I'm just stating these are things people have seen. Obviously not saying the blue tinge along w/ the yellow whites occur at the same time. Yes I have seen the screen numerous times, and a co-worker was the one to tell me about the yellowish whites.

Pentile on the original SGS/NexusS wasn't nearly what it is on this Galaxy Nexus. Last night I spent about an hour comparing and contrasting between his iPhone4s and my brand new Galaxy Nexus. When it came down to it, the Galaxy Nexus had the same readability as the vaunted Retina display, but with deeper blacks, and generally more vibrant (ermm, oversaturated) colors. Looks great to me, but people have different preferences.

i've had the moto droid, moto atrix, htc thunderbolt, iphone4, and this is by far the nicest screen ive ever had.

Are you just quoting other posts or do you actually have a GN? If so does the screen look yellow, blue, or pixelated to you? If it does I would return it ASAP because it shouldn't. Mine and the ones I've played with in the store do not.

Pentile? What Pentile?
In my experience, the pentile isn't an issue. The screen is (theoretically) gorgeous, however (and maybe I'm an exception), I've seen that only about 1 in 3 GNexi have a screen that truly looks like it's supposed to. I'm on my third GNex, two of the three have had different screen issues, and the third had a great display but a blown earpiece
That being said, I wouldn't hesitate to buy one, just be sure to THOROUGHLY inspect it before you leave the store. I'm going back for my fourth today.

My co-workers device's screen white's looked yellow. I went into the store to mess around w/ the device and did notice the same on those units. There have been others stating there is a blue tinge, which is supposedly a normal thing, as to preserve the blue pixel. The screen has minor pixelation but it's not too noticeable like the Moto devices.

You must have microscope eyes then. I can't see any pixelation holding device from one palm far from my eyes.

I do have very good vision yes.

No pixelation that I can see, and I use a lot of different types of high res screens for work. I'm really not sure how anyone can say they see pixelation on such a high density display. Take a look at the 'unlock' circle on the lock screen. You have to look realllly hard to see the jagidness - and this is a circle drawn with square pixels
Colours are slightly over saturated which makes them pop more, however they are not technically accurate - if you care. Eg. look at a photograph from a SLR camera on the gn vs a high quality computer screen.
The only real issue I see is the artefacts (grey 'dirty' look of white backgrounds) on the 2 or 3 lowest brightness settings. This is slightly annoying because you need to leave auto brightness on to preserve battery. You can however use a custom rom to change the lowest limit of brightness.
Trust me, when you turn it on, you'll think the 'google' logo that comes up is actually a sticker on the screen, and when the startup animation starts you'll fall off your chair

I will say that I can notice some pixelization of text, primarily on colored text (reds, blues, purples, etc. are the worst offenders), although that's not to say it's terribly pixelated, but it is noticeable if you know what you're looking for. Certainly nothing to dismiss the phone for, but to say it's not visible is untrue.

i can see it's pentile (having had a nexus one I know how it looks) but it's not much of a problem, the resolution is high enough. Sure it would be nicer if it was RGB, but it's good enough for me, at least (and I hated my N1's screen)

I agree. Overall I like the display better than my iphone 4, but it does have flaws, and I think the sharpness of the apple retina is better. Still, the blacks are to die for, and I like a little more punch to my colors since I'm not going to be doing any color-sensitive work on a phone. Plus, the size on the GN is juuuuust right.
Though I have to disagree with the poster that said the opening animation looks incredible. I was actually severely disappointed that they chose such a low res animation to "showcase" the HD super amoled display. It should be in native res, but it obviously isn't. That said, it would probably slow down the boot process considerably if that were the case, so it's just fine the way it is.

PenTile, yes. Excellent quality, also yes.
Unless you are a photographer, the colours shouldn't matter that much to you - white is still pretty white, and black is very black, and everything inbetween is pretty damn good too.
Those complaining about pixelation on the screen...well, to be honest, I can see pixels on my PC monitor, and it's a fancy-shmancy 1080p 120Hz 3D monster. I can see pixels on a Retina display. Pixels are everywhere.

Tab S 8.4 vs. Xperia tablet z

I am thinking about buying this one on account of the superb screen but seems that there are a great deal of lag happening, is it so?

I can't compare with the tablet Z, but I own a Tab S 8.4, a Nexus 7 2013 and a Note 8.0. I will try to answer your questions based on my experience:
The tab S 8.4's screen is a huge disappointment to me. It looks awesome in bright environments, the high pitch and vivid colors are pleasant to my eyes. However, for someone with high expectations as I did, it suffers from several issues that used affect previous AMOLED generations and totally ruin my experience:
- Smearing on black backgrounds. An issue that was already reported on Galaxy S4, and that seem to affect Tab S 8.4 as well: A dark red smear is visible when watching movies on black backgrounds. It looks like black pixels are slower at displaying a color than already lit pixels. The result is not obvious on first watch, but once noticed becomes a nightmare in dark movies.
Here is a fix for this issue: http://forum.xda-developers.com/showthread.php?t=2259775
While this seem to be pretty efficient fixing the smearing issue, the result is not perfect, it is rather annoying to use AND we lose the benefits of perfect blacks in the darkness. And it impacts battrery life, as a dark grey pixel is powered, while a black one is not.
- Mura effect. Basically, dark (but not black) colors are not homogenous on the screen. It is only really noticeable in the darkness, wich is my main usage for the tablet. Rather annoying, especially since the fix for the smearing issues induces replacing all "black" by "extremely dark grey", which reveal this issue.
More information on mura effect: http://forum.xda-developers.com/showthread.php?t=2108073
- Yellow/greyish tint. This one is'nt the worst, but can be felt on white backgrounds. This one becomes obvious when compared directly to a more natural white screen: the middle of the screen seems more yellowish and darker than the borders. It seems like the glass could be dirty, or tinted by years of heavy usage, which it is not.
None of these issues are obvious to someone who doesn't set his standards very high. They are for me though, and will probably be noticed by people willing to use the tablet in the darkness.
As a bottomline, I actually prefer the display offered by my Nexus 7 or iPad mini retina rather than the Tab S 8.4's. They lack the "wow" effect of vivid colors and the perfect blacks, but provide a more homogenous experience, especially in the darkness.
Now for the performances, I don't know what's wrong with this tab. I was thinking about putting the blame on TouchWiz, but alternative launchers don't help. Rooting and turning off as many services as possible didn't either. Here is what I noticed:
- System zoom effects are subjects to stuttering (opening new app/window, for example). None of my other android device suffers from similar issues, and zooming in other apps such as web browser works flawlessly. The issue is not reliable, and seems to reduce when the same window is opened and closed several times in a row. Memory access issue causing stuttering ?
- Overall system doesn't feel as smooth as it should. Even my elder Note 8.0 feels butter smooth compared to the Tab S 8.4, which I can hardly explain. It is fast enough, but the FPS seems to be lower.
- Two of my favourite apps suffer from low FPS when scrolling: Perfect Viewer and Moon+ Reader. The poor performances make the experience with these apps less enjoyable than on N7 or Note 8, which his hard to explain considering how much more powerful the Tab S 8.4 should be.
- 3D gaming is not at its best either. Performances are clearly below N7, and maybe even lower than on Note 8. There, I guess this is the cost for the extreme pixel density of the display panel.
If you are satisfied with the services offered by your Sony tablet, I'd suggest to stick with it. The Tab S 8.4 is a very decent tablet but not perfect, and its major strenghts are also its main weaknesses.

My 10.5 tablet doubtlessly has the best screen I've ever seen on any device. Sure, a k1 is faster CPU and GPU wise, but for my mainly media consumption and Web browsing it's amazing. Haven't experienced any of the issues mentioned above so I guess pentile does detract a bit.

I can't compare with the tablet Z, but I own a Tab S 8.4, a Nexus 7 2013 and a Note 8.0. I will try to answer your questions based on my experience:
The tab S 8.4's screen is a huge disappointment to me. It looks awesome in bright environments, the high pitch and vivid colors are pleasant to my eyes. However, for someone with high expectations as I did, it suffers from several issues that used affect previous AMOLED generations and totally ruin my experience:
- Smearing on black backgrounds. An issue that was already reported on Galaxy S4, and that seem to affect Tab S 8.4 as well: A dark red smear is visible when watching movies on black backgrounds. It looks like black pixels are slower at displaying a color than already lit pixels. The result is not obvious on first watch, but once noticed becomes a nightmare in dark movies.
Here is a fix for this issue: http://forum.xda-developers.com/showthread.php?t=2259775
While this seem to be pretty efficient fixing the smearing issue, the result is not perfect, it is rather annoying to use AND we lose the benefits of perfect blacks in the darkness. And it impacts battrery life, as a dark grey pixel is powered, while a black one is not.
- Mura effect. Basically, dark (but not black) colors are not homogenous on the screen. It is only really noticeable in the darkness, wich is my main usage for the tablet. Rather annoying, especially since the fix for the smearing issues induces replacing all "black" by "extremely dark grey", which reveal this issue.
More information on mura effect: http://forum.xda-developers.com/showthread.php?t=2108073
- Yellow/greyish tint. This one is'nt the worst, but can be felt on white backgrounds. This one becomes obvious when compared directly to a more natural white screen: the middle of the screen seems more yellowish and darker than the borders. It seems like the glass could be dirty, or tinted by years of heavy usage, which it is not.
None of these issues are obvious to someone who doesn't set his standards very high. They are for me though, and will probably be noticed by people willing to use the tablet in the darkness.
As a bottomline, I actually prefer the display offered by my Nexus 7 or iPad mini retina rather than the Tab S 8.4's. They lack the "wow" effect of vivid colors and the perfect blacks, but provide a more homogenous experience, especially in the darkness.
Now for the performances, I don't know what's wrong with this tab. I was thinking about putting the blame on TouchWiz, but alternative launchers don't help. Rooting and turning off as many services as possible didn't either. Here is what I noticed:
- System zoom effects are subjects to stuttering (opening new app/window, for example). None of my other android device suffers from similar issues, and zooming in other apps such as web browser works flawlessly. The issue is not reliable, and seems to reduce when the same window is opened and closed several times in a row. Memory access issue causing stuttering ?
- Overall system doesn't feel as smooth as it should. Even my elder Note 8.0 feels butter smooth compared to the Tab S 8.4, which I can hardly explain. It is fast enough, but the FPS seems to be lower.
- Two of my favourite apps suffer from low FPS when scrolling: Perfect Viewer and Moon+ Reader. The poor performances make the experience with these apps less enjoyable than on N7 or Note 8, which his hard to explain considering how much more powerful the Tab S 8.4 should be.
- 3D gaming is not at its best either. Performances are clearly below N7, and maybe even lower than on Note 8. There, I guess this is the cost for the extreme pixel density of the display panel.
If you are satisfied with the services offered by your Sony tablet, I'd suggest to stick with it. The Tab S 8.4 is a very decent tablet but not perfect, and its major strenghts are also its main weaknesses.

Your answer was perfect for my needs as my main utility for Tab S would be perfect viewer and moon reader as well.
Reading all sorts of experiences I'm beginning to wonder if I should buy a new tablet or not and it seems that I will rain check this purchase for now...

since in some country you can like send it back if you not satisfy kind of sale.. and if it apply to you why dont you test it. i dont have any problem like being mentioned above. and in this short period... i think the QC of the device are kind of loopy... some got great functionality without any problem and sadly some does.

Regarding the screen, I couldn't find reports about the issues I mentioned above for the Tab S 10.5. It looks like the screen on the 10.5 is using a newer technology that would fixe these issues. I so wish it would be the same for 8.4 !
Not everybody is noticing these issues on 8.4, but then I believe it to be related to lower sensitivity to the issues. They are not obvious at all, and basically impossible to notice in lightened environments and/or watching colored images.

I'm not having any of the issues you highlighted with the screen. If you have already voided your warranty it would be interesting to see if you have the same issue with my asop build.

Not having any issue with my tab s 8.4 here... love this tablet.. i was a user of nexus 7 2nd gen..

As a newb at flashing roms, I didn't go further than rooting at the moment.
Regarding the screen, while I am surprised that people report not noticing the issues at all, I am convinced many just don't notice them.
The smearing is actually more felt, guessed than seen. But once noticed, it becomes an annoyance.
The green/yellow tint is only visible on white backgrounds and when comparing to other screens or looking at it for a duration (reading e-books or internet webpages). It's far from being obvious on first sight.
The Mura effect however should become obvious to anyone looking for it. You can try with the follwing steps:
- Download and install screen adjuster.
- Get in the complete darkness
- Launch Screen adjuster, and set Red, Green and Blue to +5. Make sure it's switched on
- Look at a completely black background
=> The black background won't be black anymore but very dark grey. This is what Screen adjuster did by adding +5 in each color. If the screen is affected by mura effect, some areas will be lighter grey and others darker.
This is an issue that affects the 3 tab S 8.4 I tried (I exchanged it twice), as well as my Galaxy SII and my PS Vita. I just wish it wouldn't be the case, but I have yet to see an amoled display that isn't affected, and can hardly beleive I would be cursed badly enough to always get faulty units.

No issues on mine. The screen is superlative!

I've already tested mine T800 for mura with many shades of grey and no issues found.

Yes, from my readings here and there, T800 screens whouldn't suffer from the same issues. They use a different technology though, I wish T700 would be using the same.

yes. me too.
"ukael" is right.
I had this problem on my both two Samsung Tab S 8.4 LTE T705.
on first I thought it is related to that one, but after purchased 2nd Tab S 8.4 T705, I noticed screen going yellowish.
specially in middle screen while in horizontal rotate specially reading something that has white background.

Clarity/resolution

The OnePlus 3T has a crazy crisp display. Just kidding, this is automated text so who knows if this screen is any good. So, you be the judge! A higher rating indicates that it's extremely sharp and clear, and that you cannot see pixels with your naked eye.
Then, drop a comment if you have anything to add!

How do you find the sRGB-mode? I dont like it at all. The colours are not colourful any more in that mode. I find custom mode full warm the best though...
What about you?

Same, custom mode with full warm is my fav so far. Whites in other modes looks little blueish to me.

At first I thought S-RGB mode to be very bland in comparison with the default's vibrant colours. But after trying out the S-RGB for a day straight I don't want the default anymore xD
Everything seems much more realistic, accurate, not overly saturated, and even soothing/calmer with S-RGB. Default now gives off a wacky vibe, like I'm high or something
Edit: Tried custom full warm like the posts above, but I don't like it during the day. At night it is good, but still prefer the S-RGB for most of the day.

I really dislike the screen of the OP3T and I'm probably going to return mine because of it.
Unfortauntely I can't post an image comparison I made but you can probably see it for yourself: get some app with sharp edges in the UI and black on white text (Now for reddit, for example), you'll notice a bit of color fringing around the text, typically some green above and purple below the characters' lines. This makes text look somewhat out of focus and uncomfortable to read.
It really sucks compared to my Nexus 5's IPS screen, sure more vibrant colors but what use is that if it can't display text in a readable form?
Too bad, I really like the rest of the phone. Now I'll have to go back and look for another affordable dual sim high-spec phone.
(This is my second OP3T after I returned the first one believing this was a manufacturing defect, after some looking around it seems to be a result of the screen being a PenTile AMOLED display at a too low resolution for the size)

i now have a huawei p9 with 1080p ips lcd and 5,2". i like the uniformity and the "sharp edges" (no pentile matrix) of the display.
anyone in the same boat and did a "downgrade" to the OP3T amoled screen?
i`m a little bit afraid of uneven gray level (yellow on one side) and fuzzy fonts which are not so comfortable readable as on a lcd display.

l like the phone specs but worried about the low resolution screen - anyone have this and the s7 edge and can compare the screens ?

sRGB mode is really great in my opinion --> the calibration in this mode is great, so you can be sure, that everything on the web and in apps looks as the creator intended, as sRGB is for the time being the "standard" color profile.
I have no problem with the pentile matrix and 1080p resolution --> while I can notice a difference in sharpness compared to the OPO with its 1080p IPS display, the display of the OP3T is all around great. I would put the sharpness of the OP3T around the sharpness of the iPhone7 (non plus) with its 326ppi.

The sRGB mode on the OP3 is way better.. The OP3T sRGB mode is definitely pretty washed out with a lot more yellow tint..
I'm sure one plus can tweak that.. Nothing inherently wrong with the screen coz I think they're the same..

I'm calling BS on this one. Smells like a troll...

I just got OnePlus 3t for a week. The screen sharpness look okay to me, I have s6 and s7 edge to compare and I can't see any pixel in these phone except both samsungs look sharper. The only complaint here is that the screen panel doesn't look very black when see in daylight and not as vivid/warm, compare to my iPhone 6s. But custom setting to nearly full warm help a lot.
I use to be afraid of the pentile 1080p too, but now I can say it look very great.

I'm disappointed in the clarity of the screen, it looks quite pixelated and grainy to me. I can't understand why OP didn't go for a QHD in the 3T

I preffer 1920x1080 in my 3T, the screen has a lot of quality in my opinion, I don't want anymore.

I don't like the screen at all, it just isn't as sharp as other phones compared to today's standards its not great. Im quite let down by it.

It's decent in my opinion
I came from Galaxy S6 and its (well, let's face it) outstanding quad HD display and actually the downgrade in resolution is in fact noticeable for me. Not a big deal though, it may be just me being crazy about some minor details

Agreed, I'm used to using 2k screen phones and I'm perhaps being a bit OCD about it. The 3T screen isn't bad by any means, I can just see the difference from my old 2k phones which is annoying me. I'm also noticing the PWM on the screen and that's something I've not noticed in phones since I had my old Note 4.

Exactly, I totally agree with you

Such an amazing phone but the 1080 pentile is ugly, you're only getting an effective resolution of around 900p because of it. I feel the phone is spoiled a lot because of this.
sRGB mode is a must also on this panel.

Coming from a Moto X Pure, which has a 1440p display, I can definitely tell the difference, especially when I resize my desktop icons using Nova Launcher, with the display set to small on Nougat. This phone however is blazing fast compared to the Pure, so I'll be getting used to the display and set my icons to a somewhat smaller size (120% instead of 130%.)
I have no reason to root this thing either, except for a custom kernel with KCAL support and using Kernel Adiutor-Mod. None of the sRGB settings are good enough for me. I need Samsung-like bleeding color settings.
EDIT: Solved the blurry icons with Nova by disabling the "Normalize icon size" option.
