[Samsung Galaxy Note 9 Questions & Answers] ankydu:
I have in the past used Note 1 then upgraded to Galazy S4 and now Note 9. When I tried all these devices in store before buying. Their screens appeared to be excellent. But once I bought them and used them for a few days I slowly started to see issues with screens. The note 1 I had slowly developed this redness on right edge of the phone over time visible only on grey background under low brightness. I got it replaced 3 times but then gave up. After that when I switched to S4 it had this reddish top and greenish bottom visible only on low brightness and white or light grey background. I got it replaced once and again got a similar screen with the same issue plus overall slightly yellowish tint on the whole screen. So once again I gave up and was using the same device from past 5.8 years. Now when I tried the Note 9 in stores i just loved the screen and ordered it. Now after using it for a few days I find on light backgrounds that the screen is slightly brighter at the bottom than the top. In fact it's like it's whiter at the bottom than at the top. I was thinking are there amoled screens which have uniform whiteness/brightness across the screen. In all other aspects the screen is perfect to me but this issue once I know it's there is somewhat annoying to me. How is your screen ?

dont think they had oled on the note 1 or s4 yet. but i can assure you that since Samsung made OLED, these screens are the best out there. and to tell you the truth, any 2018 screen would trump what you may have experienced in the past.
[Samsung Galaxy Note 9 Questions & Answers] ankydu:
The note 1 and s4 both had super amoled screens. The screen on note 9 is certainly much better but not perfect as I have mentioned in my first post.
[Samsung Galaxy Note 9 Questions & Answers] bober10113:
yeah i just double checked an your right thy did.

what models re you buying? us or international?

also you might want to try and condition your screen.

oled tools is but one example of apps that display static images at full brightness.

I've had a SGSII, a Note 4 and I'm currently using a Note 8. All of SAMOLED displays have been really good with no issue as you have described.

You do know that Sony is failing in the smartphone department right? They currently in the same situation as LG. Unfortunately, the screen won't save their smartphone division.

Edit: Playstation is where Sony gets their money these days. Sad to see.

"A growing thorn in Sony’s side is its mobile handset business which counts its revenue, primarily from its Xperia line of handsets under the Mobile Communications segment. Sales of $6.88 billion were down 5% from the previous year and the group posted a loss of $255 million.

The mobile communications group guided to a further 12% drop in sales for fiscal 2018 and a projected loss of $138 million. The group does see some light at the end of the tunnel – 5G wireless technology."

They gave been losing money year over year, quarter over quarter man. Their lack of innovation is dragging them down like LG.

By the way, last edit. Sony didn't make that OLED screen. LG Display did.
[Samsung Galaxy Note 9 Questions & Answers] teegunn:
Displaymate rated the Note 9 as having the best display ever on a mobile phone. Just as they did for the S9, and Note 9 before that. Pretty much every new top of the line Samsung device trumps the best there was before it.... and the best there was has pretty much always been on a Samsung device. Sammy makes the best displays.

In any case, you can find other very good displays on other phones that look pretty much as good, but when a place like Displaymate puts a "best ever" sticker on a device's display, it is for a reason. Note 9 display is not much different than the Note 8 display for instance, but it is enough of an improvement to warrant the top billing from Displaymate.

Here's that survey, the Note 9 is MIA, how convenient.

https://www.androidheadlines.com/20...-display-is-the-best-claims-a-survey.html/amp

Can't go wrong with either, but, just wanted to post a credible link vs your inexplicable need for the attention from trolling...
[Samsung Galaxy Note 9 Questions & Answers] bober10113:
that article never named its source. could have just as well been sony propaganda. love how the article starts with " claims a survey.." of what? 2 or 3 clueless dudes? Maybe Karandeep Singh got payed a couple of rupees..or even a sony phone out of it

edit:

and now since what's on the internets is always "true", people acctualy believe anything nowadays if its well framed and worded.
[Samsung Galaxy Note 9 Questions & Answers] KOLIOSIS:
Actually,it appears to be nothing more than a marketing company hired by Sony:

https://www.sonymobile.com/global-en/legal/testresults/xperia-xz3/

https://www.strategyanalytics.com/

https://www.bloomberg.com/research/stocks/private/snapshot.asp?privcapId=1051783

All companies on this level tend to use such garbage "research" for marketing,all claims like this should come with an e-coupon code for a pinch pound of salt.

What's worse is peeps getting their panties in a wad,feeling the need to either rationalize their choice in phones,trolling those that have "x" phone,& the fanboi behavior that's fueled by the fluff articles.

The Note 9 is a nice phone,got one myself.

Is it the absolute best out there? In the eye of the beholder & nothing more.

Others choosing something else is equally fine,one would be hard-pressed to actually find a truly terrible phone w/o intentionally seeking one out.

Note 9 earpiece smudges won't go away

Hey I guys I bought the note9 from 6 days ago. One day I was just rubbing the top bezel ( the space that has selfie camera, iris, led, ect) suddenly I saw 2 smudges, one above the earipeice, one under. I kept rubbing it and it doesn't go away. I believe that maybe when I was rubbing my hands were sweating so water entered beneath the glass. Here's a picture I posted here so maybe you'll get what I mean. If anyone has this issues or fixed please share it here. If the attachment is not working please say.

Thanks

Ahmed
[Samsung Galaxy Note 9 Questions & Answers] KOLIOSIS:
Take it back & exchange for a new one.

Any attempts to fix it on your own will likely make it worse.

Don't waste a minute waiting for home remedies here, utilize the return/exchange policy for a free replacement before that period expires.
[Samsung Galaxy Note 9 Questions & Answers] ankydu:
All note 9 owners can you please open any site with white background in google chrome and when the phone is held in hand in portrait mode do you see even slight difference between the white levels at the top and bottom of the screen. Please reply. Its very slight but its there.
[Samsung Galaxy Note 9 Questions & Answers] marctronixx:
No

Just looked at a note 9 i have and the note 8 and using chrome on a white (blank) home screen i dont see any color shift at the top or bottom or anywhere on the screen.
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
I opened Samsung browser with no tabs open white screen. Slightly yellow or warm color. Looks pretty even but if I were to be extremely critical top side is a more darker maybe.

The white is definitely not like the note 8 white . Using amoled photo with slight blue light setting.
[Samsung Galaxy Note 9 Questions & Answers] teegunn:
My Note 9 has an even white color across the whole screen. It also has a bit truer whites than my Note 8. Part of that may be that my Note 8 is now a year old, but overall I believe Samsung tuned the contrast down a bit on the Note 9 from the Note 8. Just to be clear, I am using the exact same display settings on both phones.... so I am getting an accurate comparison of the Note 9 vs Note 8. There is very little difference, you'd have to literally be looking at them side by side to notice the slight difference.
[Samsung Galaxy Note 9 Questions & Answers] bober10113:
looks as if you have a glass or plastic film. the cutout of the speaker is to high for it being the original glass
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
Compare home screen icons on the note 8 and note 9. Let me know what difference you see. I see the note 9 not being as sharp. But then on the same token , the note 9 like I said earlier is more natural and appeasing to the eyes.
[Samsung Galaxy Note 9 Questions & Answers] ankydu:
Exactly that is what I am trying to say. The screen is beautiful with the best whites I have seen on a amoled screen and its pretty even as well. But my eyes seem quite sensitive to screens and I also feel the top is somewhat darker.
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
My eyes have always been sensitive to the uneveness of the samoled screens in the past. But my current one , I'm happy with.
[Samsung Galaxy Note 9 Questions & Answers] ankydu:
Ok one last thing all note 9 owners please try. Set the screen to adaptive mode and brightness to about 20-30% and turn off blue light filter if you have it enabled. Open any square or 4:3 photo in samsung gallery app. Touch the photo once and you will see white bars on the top and bottom of the photo. They appear briefly and disappear. To make them visible for longer tap edit. Now just see if both the white bars at the top and bottom are of exactly the same color or there is slight difference?
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
Very hard to tell even by my fussy eye standards, perhaps the bottom is slightly darker I can't confirm.
[Samsung Galaxy Note 9 Questions & Answers] ankydu:
Yes its very very slight but its there.

[Samsung Galaxy Note 9 Questions & Answers] Jammol:
OP, I am seeing it on mine. I tend to use dark themes on my device so it's not very noticeable for me. I also shut my brightness all the way down to the lowest at night.

I checked all the Note 9s we have here at work, 17 total, and they all have the same darker shade. Do you think this is a defect or it's a "this is just how they are?"
[Samsung Galaxy Note 9 Questions & Answers] ankydu:
I feel probably your second statement is right. Amoled screens are never even with brightness/whites across the screen as far as i have seen and i was hoping probably Note 9 will be perfect but its still not. No doubt its got the best amoled screen I have seen with regards to screen evenness and true whiteness but its not perfect. Indeed it has come a long way in screen quality as it doesn't suffer from those color banding or blotches or severe screen color shifts of previous gen amoleds. Those who say they have got a perfect amoled screen are not critical enough about the screen quality as some of us are and its perfectly alright. Everyone 's definition/perception of screen quality is different. I am a graphics designer and hence am very critical about properly calibrated displays. In fact I would say I am a little over critical. So I wanted to know if its just my screen or all are like that and based on your feedback it seems most if not all are like that.
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
Just ran display tester pro by Braintree. Used to use this paid app since my note 3 days. Uniformity has much improved since previous models. My pet hate used to be the blotches. I guess we're in for a treat when the first batch of foldables is released, with treat I'm being sarcastic since I feel it'll be issues with color shift and blotches all over again, until it's perfected.

Samsung AMOLED Quality Issues

Dear all,

I own Samsung devices with AMOLED screens since the Galaxy S2, then hat EVERY Note (except the 5 which did not make it to europe).

Samsung had ALWAYS very different screens in one and the same product. About 10-20% of the screens are almost perfect, ALL other suffer more or less from uneveness or color tint.

If you 5 Note 9 devices beside each other, you will notice that every screen is little different. some have a red tint, some yellow; some have uneven colors across the screen (or different brightness, example a bright screen at top and slightly darker at the bottom). This is due to manufacturing differences, and most people dont notice. If you once noticed it it is very hard to ignore it in the future.

There ARE almost perfect screens, and until now I EXCHANGED EVERY SINGLE SAMSUNG DEVICE I HAD FOR A FEW TIMES TO GET A GOOD ONE!!

I started a few threads about that in the past, please take a look, the basic issue is still the same:

https://xdaforums.com/galaxy-s8+/help/s8-amloed-display-quality-red-tint-t3593263

https://xdaforums.com/note-4/general/note4-amoled-screen-quality-t2906365

https://xdaforums.com/showthread.php?t=2463786

Be happy if you dont notice this, but if you are cursed like me, you would be unable to ignore this. And you will have to exchange your devices a few times until you have a "decent" screen! ;)
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
Im cursed like you and am happy with the note 9 display.
[Samsung Galaxy Note 9 Questions & Answers] @rbiter:
Appreciate you keeping the cost of manufacturing so high. I bet you don't even have a colorimeter or spectrometer.
[Samsung Galaxy Note 9 Questions & Answers] TML1504:
lol, you really think that my returns have an influence at millions of devices sold?

besides, samsung does the right thing, in terms of QC and customer satisfaction: most screens are slightly flawed, but as long as 99,9% of all customers don't bother, because they don't care or don't see it, all is ok.

what about ranting against me in regard to an measurement device? you're a long time senior member, just as me, so calm down!

I certainly do not need to measure anything to be able to say that there are big differences in screen quality due to manufactoring! everybody who have eyes can do that by placing a few devices (with exact same settings) side by side. it's easily seen...

for example google for "s8 red tint", and look at the pictures with comparisons...
[Samsung Galaxy Note 9 Questions & Answers] @rbiter:
First world problems. I came from a V20. The image retention on that was ridiculous. Last time I had a perfect screen was a plasma. Maybe my note4. Yes, I think the cost goes up. Screens are binned like silicon. It seems like every new phone people look for flaws intentionally. My phone didn't come with a swappable battery, the long edges are rolled over and somebody can't tell what right angle is. All 4 of my corners are rounded. My notch is crooked. ???
[Samsung Galaxy Note 9 Questions & Answers] TML1504:
You are right, this are first world problems indeed. And I would be really happy if I could ignore this flaws.

I have been at a local store here in Vienna today. I looked at a few Note9 on display, and compared their screens: It is as I feared: All screens looked different, some had yellow tint, some were more bluish. Only one out of 5 screens looked really good to me.

With Note9 we have the "display lottery" again, as usual with Samsung Amoled devices... :|

I showed this to the Samsung rep there, and even he agreed that this is not nice and he preferred the from my opinion "good one" as well.

One screen has been really bad, it looked like it has a slight yellow shade over the whole screen. Even worse, the right side of the screen has been darker then the left one. Over all the screen looked less vibrant or clear as the good ones.

Again, I do not want to bother you or any other user with that, but it surely exists. On S8 it has been so bad that even mass media reported it to that time.

As it seems most people do not care about that, but I think we (at least the old users before about 2010) freaks to some extent, otherwise we wouldnt care as much about our phones. It COULD be that my reports and exchanges increased the price of your device for 0,0001 cent, if you want I would be glad to compensate you if you want, just provide me your PayPal per PN. ;)

But I think this would really cost you nothing, because Samsung let these devices pass the QC, which is economical the right decision, because almost no customer complains about that. Nonetheless, the problem with the screens exist!

1249€ is not cheap, and I think it is appropriate to demand a good screen. Therfore I want an almost perfect device, because I know that they exist.

What do other users say, did you already have the chance to compare your screen with a different Note9? Be careful tough to use the exact same display settings, otherwise the test is not objective...
[Samsung Galaxy Note 9 Questions & Answers] @rbiter:
My note9 screen is great. I compared to my note4. Almost anything would be an upgrade over the V20 screen. I have seen image retention and burn in on LCDs before but not like that. No reason I should have had some of the image retention I had. And the V20 took great picture but had a lousy screen and it is nice to know what your pictures look like right away and looking just as good on a monitor. So the V20 camera was just used for fine details my aging eyes that can't see anymore. It sucked having a slight dread using the V20 camera because of the terrible screen quality. Actually, my note9 screen is close to perfect. I didn't look for serious flaws. Just dead pixels, tint and screen uniformity. No dead pixels, white is white and uniformity is close to perfect, if not perfect. Even then I have never had to dwell on a bad screen. Nothing ever stood out to complain about. The V20 didn't exhibit symptoms until deep into ownership. I hope the note9 ages gracefully much like the note4 has. I still have it and I was still using it but no need now. Will probably sell the note4. It is hard to use now because the s pen latency is excruciating compared to the almost 1:1 latency of note 9. Nobody has come up with a number yet. My guess is around 15ms ±5ms.
[Samsung Galaxy Note 9 Questions & Answers] ankydu:
Sadly here in India it almost impossible to convince Samsung reps about screen issues. And exchange is possible only in first 7 days from date of purchase. That too only happens if they are convinced. I remember during my Note 1 days I purchased it 3 times and returned at seller level. Finally I bought it the fourth time again to have a reddish right edge of the display visible only on grey background. Had a tough and long fight with the samsung service guys to get them to replace it. And got it replaced with a acceptable one if not perfect. I remember the Samsung service guys advising me to be a little less critical of the display. Later on I won a Galaxy S4 in a contest in my country and it had this horrible top red and bottom yellow screen but I didn't bother getting it replaced as I didn't find it worth getting exchanged what was a free prize. But now looks like it is bothering me with Note 9. And what is even stranger is the screen looks better balanced when viewed upside down in portrait mode. It looks totally uniform. But in normal mode the top is certainly darker than the bottom. I also have a cheap tampered glass screen protector installed which is highly reflective. Don't think it can make the screen appear uneven or can it?

From youtube when playing video 4k hdr in darkness the screen flashes.In the light, does not matter how weak it is, no problem.
[Samsung Galaxy Note 9 Questions & Answers] Limeybastard:
My cheap tempered screen protector would make the display black look gray. One can notice it when with the screen turned off. So I wouldn't rule that out as a possibility.

[Samsung Galaxy Note 9 Questions & Answers] Jammol:
Actually your returns do have an effect on the manufacturing costs and the likelyhood of price hikes. Each device you return is now deemed used and must be sold as such. Let's say they sell it used for $700. That's a $300 loss on their part because you returned a device that's manufactured with screen technology that hasn't been "perfected" as yet.

Now let's say 50 people from XDA alone return their device for a new one because of the "defects." That's $15,000 lost. That amount not only affects Samsung, but also the carrier you purchased the device from if you did get it from one of them. That $15k only tallies for the device cost itself. Then you have to add in shipping costs, inspection costs, re-certification costs, yes that's a real thing depending on where in the world you are; and more shipping costs to then send the device out for resale as used, packaging, labour, etc. I can go on and on. That money adds up really quickly, and that's only from 50 people.

Everything we do in life no matter how small it is has an impact on something or someone somewhere.
[Samsung Galaxy Note 9 Questions & Answers] @rbiter:
What jammol said. The biggest loser is Samsung. I'm quite sure Samsung calibrates their screens to certain tolerance because we have great modes to choose from.

Samsung makes decent TV's and monitors too. Samsung makes some pretty good flagships and if you don't buy Samsung's bottom shelf (these are cheap for a reason) Samsung is known for having the best color accuracy out of the box. Still many of their big screens have a uniformity issue or tint. But I don't watch white screens. Probably the last 2 years they stepped up their mobile OLEDs because they knew Apple was coming around to OLED soon. An expensive premium we have enjoyed for much longer and many Apple fans boo'ed it because, Apple.

As much I dislike Apple and even though my first 2 iPhones were defective they had excellent LCDs, especially for a mobile device. But all those returns add up for Samsung and Apple. The bigger cost is all the bureacracy going back to have human labor put a sticker on it and then often resold at a lower cost. It adds up. Sales have slowed down for Apple but they're still making huge profits. They're still putting pressure on manufacturers of iPhone parts to lower prices because their profit margins aren't high enough. And they already get economy of scale pricing (because Apple doesn't sell many models which all have 90 something % same parts) and sometimes longevity because sometimes no part upgrade on next iteration so nothing has to be retooled. What jammol was saying butterfly effect.
[Samsung Galaxy Note 9 Questions & Answers] ankydu:
All I am reading is some have really bad and some have (probably perceived) near perfect screens. Does that mean there are no Perfect and not near perfect OLED screens out there with uniform whiteness across the screen?

I have a 3 yrs old Asus fonepad tablet with 8" HD resolution LCD screen and though sharpness and crispness wise its crap, it has much better uniform whiteness across the screen compared to all Samsung and apple OLEDs I have seen.
