More bright, more tint vs less bright, less tint

Okay, everyone pretty much knows no two SAMOLED screens are the same. I recently bought a second Nexus S (because I kept hearing people say it has "amazing" battery life whereas I was getting nothing better than my Vibrant) and decided to keep my first one (I will return it later) to compare. The second NS definitely has a slightly brighter screen, but it also has a much more apparent purple tint. The first one has a slightly less bright screen but the purple tint is also very minimal, hardly noticeable unless one is looking for it.
Any suggestions on which one I should keep?
P.S. Both phones batteries behave similar so I guess everyone's definition of "amazing" is my definition of poor.

i personally hated the purple tint. if you dont mind the 'unnoticeable unless pointed out' defect, go for the one with the lower brightness. also, check your whites on both phones because mine had a problem displaying true white.

second phone definitely has "purplish" whites.

My personal preference is to have more accurate colors. If the white isn't white, it's not acceptable for me. I'd go for the less bright one, as long as it's bright enough.

Mine has a blue-ish tint when it's white... really annoying. Also there's banding when I swipe down the notification bar (the dark grey background... lots of odd colored lines). That and my oleophobic coating is wearing off, gonna exchange in a few days. I really hope I get one with a warmer tint so the white looks more white... I don't care if it's slightly less bright, it's too bright as it is right now anyway.
EDIT: Actually I just tried screen calibration under cyanogen rendering effects... using the N1 cool setting makes it a tad warmer, whites look white now, but it's SLIGHTLY less bright than before. Whatever, better colors, I like it for now until I exchange.

just for you info, the blue-ish white is the actuall true white . its the better screen than the purplish white. and once you comapre them both head to head, you are gona kiss your phone.
i am not aware of your other issues but if they are annoying you, then just exchange the phone.
god knows how many weeks i searched for cool blue-ish white for my galaxy S and then iphone 4. i hate the warm yellow /purple-ish color from my heart >_< " its a friggin defect "

This is how your NS should look in your screen while in the clock homescreen . If it looks any different, then its not right. Usually there's a purplish tint in the bottom tabbed icons on the lowest bright settings. You'll want to find one thats closest to this display

After doing the test mentioned above (Clock -> hit the brightness setting on the top right corner), I notice that the lower buttons are purple/pink tint.
Does that indicate a defective display? Also, after a few seconds, it dims even more, and the entire screen has a purple/pink tint.

Seems like some super poor quality control if there are huge variances in SAMOLED display tech coming out of Samsung... =[

purple = defective. bad screen
cool blue = good screen.
the end of the day = personal taste. but compare a purple screen to cool blue screen when you set the brightness to the highest on a white background. the difference is night and day

Gah, I knew there was something horribly wrong with the purple.
This is my 2nd unit and I'm not sure if I want to exchange it and take another risk of getting a faulty unit.
My first unit had a faulty back button and this one has a loose volume rocker (not too concerned about), and just found out that the screen is defective.
Now that I think of it however, I'm rarely on low brightness and high brightness.

good luck thinking about it before you go to sleep and you actually sleep.
and if you did, you will have nightmares about it

As I mentioned before, I'm not sure if this really considered a defect in the eyes of samsung because I've yet to see one displayed like the the 2 photos I've provided. I know this because of the inconsistencies I've personally seen with the N1 screens myself, and certain batches of N1 would have varying degrees of the purplish tint, some worse than others. It stills baffles me how they let this bleed over into their NS lines. My NS still has the issue but out of all the NS I've seen so far I've lucked up on the better out of the other evils.

As scary as it may seem, I did have nightmares about it!
I'm going to end up keeping this unit since I haven't ran into other large issues such as rebooting during phone calls, etc.

Lcd issue? Backlight on, small streaks and spots

So I was watching a youtube video tonight and part of the screen was black and I see these thick, kind of discolored lines, just a shade darker than the color of the backlight. I was like ok, just be the Youtube video, their cam was dirty whatever. Then I thought back a few days ago when I quickly noticed the same thing and put it off as nothing. Well I further researched it and found a completely black image on my sd card and displayed it at full brightness with the lights off and I found an annoying, yet not crutial, defect (maybe defect). It appears as though glue or something is on the underside of the lcd blocking light from coming through. I can barely find it if any light is displayed on the screen, but this dark video just made it seem so prominent. I wonder if anyone else has this issue or if it is infact a defect. I found it by viewing a dark image at medium brightness in a dark room. Putting brightness at 100% does make it a bit more prominent. I mean I could live with it I guess but it is extremely annoying to find something so stupid on such a great new phone. I wonder if it is a common issue and I ask you fellow gs3 owners to take a look at yours and tell me if it is just me. I have attached a photo I took with my dslr. The colors are kind of looking overdone because I had to bump my ISO up to like 6400 to even get a picture of it because it is so dark and I didn't want to run outside to grab the tripod. You should get the idea. The picture makes it look a lot worse than it really is. I have looked at the screen and I see no discolorations when the screen is off and I see nothing of that pattern while the screen is off anywhere on the lcd, but I couldn't find my super bright flashlight. What a day!

Yeah I notice this in the dark when watching a YouTube video. Its apparently a samoled issue and something I never noticed on samoled + screen on sgs2. Its very common and have seen a few threads about it. The good news is that you only really see it in a pitch black room when using the phone on a dark screen. I've never noticed it durng the day

Thanks for that. Now I know its not just me. You really settled my nerves, I was about the be pissed. The screen is beautiful beside that. It is just when it is pitch dark and I am looking at something black, otherwise, if there is probably 25% of anything else that is lit on the screen I probably won't see it. I guess I just caught it on one of those rare occasions when I am using my phone in the pitch dark.
Do you happen to know what those threads were called? I am having trouble wording the issue exactly lol

Nooo that is top much. Yes all galaxies have that issue but I think yours is too much. Exchange it i would say

Its just like this, apparently called "ink marks" Last picture in the op here
http://forum.xda-developers.com/showthread.php?t=1658601

Tbh I really only notice in landscape and not in portrait and the only ones I see are the ones on the left and the dot on the right if I do see them. I'd hate to take it back to get one with its own unique set of the same marks. Plus I rooted it and I'm not quite sure if the flash counter clicked , damn verizon

Finally I'm not the only one. It only happens with video and it doesn't matter out you play YouTube app browser or videos you have saved. And try recording and the play back is bloody red skill over the place. Best buy associates were freaking out with my old phone. Over had the gs3 replaced 3 times. And third times the charm. When life gives you lemons hope your within the 14 day trail period.

Oh and no fix apparently according to best buy its a internal defect so hopefully anyone and everyone else has time to exchange.

I might have gotten the perfect unit.. No ink spots, no tint... AT&T Pebble blue btw.

I thought the same thing until a week ago when watching something in the complete dark. For those that think their phone is perfect you'd have to check under the same circumstances to know for sure. A dark room and playing videos. I noticed it especially on netfix. I started a video and before the movie starts it goes to a black screen and thats when I first noticed. I do wonder if its all phones or if only a few of us have this defect

This is a defective samoled. While the glue blotches exist in nearly all displays, yours are especially bad. The fact that you can record them and actually see them while playing videos is the deciding factor here.
For example, I can see those too - but only in complete darkness and while the brightness is at max - any kind of video or soft keys wipe out those blemishes. In other words, those blotches should be invisible under any usage conditions. Otherwise, the quality control has passed a lemon, which is clearly your case.
Exchange that phone for a new one.

Like I said, I if there is anything on the screen I can't see it. I have the reason it looks do prominent in the pics is that I boosted iso and it exposed for the baclight. I had to try really really hard to get a picture of what was going on there

yes. i have the exact same problem. thinking of getting it replaced today.
heres what my looked like:
made it in paint

The black ink thing is a common issue but there has to be some extent to which it's too much. I usually don't notice it and I can forget about it but for those times I do, it is quite the let down. I'll probably take it to Sprint this coming week and see what can be done.
My screen...not the best picture but at least it shows the blobs. I could care less about the black marks towards the top of the image. It's just the ones on the bottom that bother me.

Ahh yours is much like mine. I have tbh, and I tried finding it today during the day and no lights on with brightness maxed and I could not. I think I am going to stop stressing about it as it is only visible in very limited situations. I thank you guys for helping me out with this and really settling my nerves to know I didn't just get a bad one and that it is quite a common issue with different variations.

i have to check mine now but either way if almost all units have it you may return it and get one that is worse

Anyone else experiencing screen color temperature variation between devices?

Just got my 1st replacement Nexus in the mail-the first one was exhibiting symptoms of a non-responsive touchscreen after heavy gaming or when exposed to sunlight. The replacement unit is almost flawless, except for one glaring flaw...the white balance on the screen is WAY off! Whites are tinted beige, and the screen looks extremely washed out and warm compared to my first one. Here's a side by side picture (not the best photo, difference is more pronounced to the naked eye).

I'm tempted to send this one back, but I don't have the time to get stuck in a RMA loop, especially as I'll be travelling this month. What do you guys reckon-should I just keep this device with it's flawed WB, return for a replacement and hope for the best, or return for a refund?
Alternatively, is there any way I can dial out some of the warmness using software? I know there is a color tuning/calibration utility that is included with CM for my Galaxy S-anything similar exist for the N7?

I had the same issue as welll. My recent replacement has better whites bit the screen is still displaying a pinkish tint. My old nexus 7 had a yellowish tint as well. I wonder what the screen temperature is actually supposed to be :\

To the OP you are correct I've started two threads already about the color correction slash grey scale issues. Most agree that Google will not be doing anything about it. Just plain luck or bad luck. Both of those are not bad mine is just in between I would say.
I have linked to this video before http://www.youtube.com/watch?v=MD8n7xaPBMo the way cool blue tint on the unit shown would be grounds for return IMO. Whites need to be white, not yellow warm or cool blue. Just try and do a side by side with an iPad 3 if you can live with the offness then do so, its a lottery at this point.
I started two threads because so many people have said this is an issues, but it varies so much and is so subjective that its doubtful Google will do anything. I prefer the one to the right just because a little cool blue is way better than warm yellow but the New one on the left looks more accurate.
Hows the Backlight bleed?
A good simple test is I go to T-Mobile.com or Engadget their Magenta Pink and Engadget's sky blue are hard to get right. But then again that opens up a new can of worms about your color Gamut and Hue which I am sure also vary device to device. Its obvious by now this is a QC step Google did not require ASUS to perform. Most likely to improve production yields.

Thanks for the informative reply. It's really unfortunate that Asus has dropped the ball so badly with consistency-I can understand lowering some standards for a $200 device to increase production yields, but they've seemingly neglected numerous aspects as evidenced by all the problems the community is having.
As for the new vs old one, the photo is not the best representation-the old device has perfect whites, completely neutral-no tinge of blue at all. Colors gamut is also pretty accurate on the old one. The new one is visibly worse-not only is the white balance off (whites appear beige), but colors are over-saturated and blown out-I noticed a loss of detail immediately just by looking at my wallpaper. Flesh tones are especially bad-much more red than they should be. I even had my roommate do a blind test between the new and old, and he immediately noted that the old device had a "sharper, crisper" screen.
As far as backlight bleed, it's not too bad on both Nexus's (Nexii?). The new one has a bit of bleed in the lower left corner, but it isn't very noticeable and is the least of my concerns at this point. I'm just not sure if it's worth entering the lottery again to see if I can get a better device based on all the horror stories I've been reading here...
Are you aware of any calibration/color tuning utility for the N7? Devs should look into integrating a utility into their ROMs. Something like this:

Sounds like they are messing with what would be called on HDTV's the Sharpness setting.Its gonna take a subpoena to find out what Google and ASUS knew about the color temperature slash calibration or lack their of, and when they knew it. I smell class action down the road. No way its just not right so many units coming out so differently.

Not only color, but I've noticed noticeable differences in brightness between the 3 I've gotten for RMAs. This new one gets darker and brighter than the previous one.

Mine is pretty much spot on, Except for Blue Links tend to be on the purple side of Blue, enough to start a few threads and ask some questions but definitely not warrant a return.
One thing I have its noticed is that its nice bright and vibrant not at all "washed out" as other have reported. But When I go into Display Brightness, (never Auto brightness) when I move the slider I have like 8 or more different levels of Low brightness below the the Halfway Mark so I can really pick to my licking how low I want the brightness, even on the lowest it maybe too bright for reading a book in a dark room.
But above the halfway mark of brightness I only get about 4 or 5 Steps Up to Max brightness, The last inch or more on the slider toward MAx brightness does nothing. So in essence I reach Max brightness well before the slider is maxed out.

That is very strange indeed. My brightness slider doesn't exhibit this-it is linear throughout it's range and the lowest brightness setting is quite dim, perfect for reading at night.

XDA developer Supercurio has an app called screen tuning for the Samsung 10.1 that I loved that changed the white temperature, which I believe is the issue. I think an app like this would help significantly.
Its also been said that the nvidia chip settings causes screen wash out after videos or heavy gaming. Its a battery saving measure while watching video or gaming but persists afterwards when it shouldn't. There's an app around here for that. Nut I'm after a color correction.

The screen tuning app can only be used with AMOLED screens, which the Nexus 7 doesn't have.

Yellow tint on S4 screen

I have this annoying yellow tint on my S4's screen, but disappears when the phone is tilted over 45 degrees. Is this faulty ? Shall I return it ? Or is there a way I can fix the gamma through an app without rooting the phone ?

I have this too, interested if this is a defect or just the colour tone of the amoled on the gs4

I have the S2 and it's blue compared to my display on computer, and I don't even notice it unless I put it against the computer display like you did.
Maybe try other display calibration, I hear you can change them.

Ok, been doing some google research on this -
There's always going to be a slight yellow tint to the particular amoled screen used in the GS4. However, to reduce the effect, set your screen mode to MOVIE.
Movie mode provides the best colour accuracy and also white point of the available choices. I can confirm this is the case having just spent a few minutes comparing colour charts to my girlfriend's very well-calibrated iphone 5.
So I would set it to MOVIE. The whites still won't be IPS display white, but then IPS can't touch the beautiful blacks on amoled. Horses for courses. Hope this helps.

@paddlyaz can you provide sources of where you got this info ? -- Edit : I just tried it, all that did was make the display washed off..Yellow tint still visible

It may LOOK washed out to you - but this is an AMOLED display, which is naturally very colour saturated.
If you compare the gs4 to an iphone 5 like I did just now, you'll see that even in Movie mode, the colours are a little MORE saturated than even the iphone 5 has to offer. The tint is a side-effect of this. IPS displays like the iphone may offer truer whites but amoled displays like the gs4 destroy them in terms of saturation and black levels.
It all depends on what you prefer on a phone.
In terms of the GS4, some people find the 'dynamic' and 'standard' modes vibrant and eye-pleasing - but they're not at all accurate and will exaggerated, innaccurate representations of your photos, videos etc. I have one photo of me in a yellow jumper (fashion mistake I know). When I have it on 'standard' it looks like I just came back from a two week holiday in Chernobyl. In movie mode, it looks exactly how it looks in real-life (i.e. still disgusting but accurate).
Here are a couple of links that describe it more:
http://www.gsmarena.com/displaymate_tests_galaxy_s4_screen_gives_it_the_thumbs_up-news-5928.php
http://gizmodo.com/5995376/galaxy-s-iv-display-shoot+out-how-does-it-compare

I wish I have another camera to show you the difference between my iPhone and S4 ... The iPhone's screen is bright white compared to the yellow tint on my S4. If this is a "feature" then it's not really efficient now is it =\
Maybe there is a way I can manually edit the gamma, this should fix the problem I guess. Or just exchange it for another one.

did you read ANY of my post?!
It's the trade off you pay for having perfect black levels and saturated colours.
The only way you're ever going to see perfect whites is if you get an iphone/htc one - e.g. an IPS display.
But then you're going to be stuck with 'blacks' that are actually grey. And that SUCKS.
People have differing opinions on which trade-off they'd rather have. Personally I'll take a slightly 'warmer' screen in return for having deep, inky blacks.

Hmm I see, so the display type is the reason why the yellow tint appears eh ? Interesting, thanks for the links too, going to check them out.

all screens will be slightly different from each other - but yes, amoled screens will almost always have either a slight YELLOW tint, or a slight BLUE tint - in other words, a slight exaggeration of one particular tone. If you have the time, do a google search and you'll see this was a common 'issue' flagged up on both the gs3 and gs2.
Your best bet is to do the following:
-set screen mode to MOVIE
-disable 'auto adjust screen tone'
-disable auto brightness.
You will never EVER see perfect whites on an amoled screen, and anyone who tells you they have them is lying out of their arse. Most reviews for the GS4 and also in the articles I linked you state that the GS4 is the most accurate amoled screen so far though.
If still disappointed, your best bet is the iphone5/htc one/nexus 4 etc

I think having an exaggerated blue tone is better than a yellow tone, in my own opinion.

Anyone else having this issue ?

I noticed this playing around with the S4 in the store. Still, much better than the S3 white point.

bad yellow tint
Hi everyone,
I received my s4 last week and found it yellowish as well. I have read everything regarding the screen yellow tint and the fact that it's because of the type of screen. I was going to give up but my girlfriend got one today as well and the comparison is very clear: her whites are so much better!
I have tried to take photos of them, and it looks greenish on the shots but you can see the difference. FYI the screen are both using the same settings: auto brightness off, brightness at the maximum, both screen mode in adapt display (I have tried the movie mode without noticing a change).
Mine is on the right if you couldn't see. You can clearly see the difference in the colour and the quality of the screen. I also noticed that the viewing angle are way worse on mine, the phone takes a greenish colour.
Finally I have very strong smearing/ghosting as soon as the screen background is black. For example when I am in the settings, if I scroll up and down, the thin lines separating the sections actually disappear whilst the menu scrolls. The thicker separator get a purple line until the scolling stops. Once again, the smearing on my girlfriend's phone is existant but much less strong. The thin separators are still visible even while the phone is scrolling.
I am definitely bringing it back to the store tomorrow. I am very disappointed with the screen even though the phone is great. I wouldn't change for a One, just for a good one.

I had the same yellow tint on screen and tried a few different firmwares thinking maybe its a software issue but nothing fixed it.
Picked up a new s4 last night and this one is perfect. The thing I noticed is the new one is assenbled in Vietnam and the old one
was assembled in China. Over all the build quality on the new one feels much better along with audio quality.
Maybe a quality control issues in some factories
Cheers

Where does it say the location of assembly ? I want to see where mine is. Also, did you exchange your phone for a new one ? How did you convince them it was faulty ?

You'll see it when you pull the battery, there should be a sticker there.
I am located in Toronto and we dont have any samsung stores here
so i actually bought another one from this dealer i found on kijiji.
The new one was sealed and its from Hong Kong (but assembled in Vietnam)
Cheers

I looked at mine and it says made in Vietnam... But I would agree to say that there is a problem with quality control overall. My guess is that they need to produce as much as possible to avoid any shortage. I had the same problem with my Note 1 and could be bothered to change it, this time I won't let it go.
I will keep you posted.

I had to go to another branch and thankfully they had a model with a white tone screen. I compared it there and they did indeed see the yellow-tone in my phone. I am getting a refund soon, it's not really worth all this trouble i'm fed up of the customer service experience with Samsung.

[Q] Note 3 Uneven Screen Color

I know there are a few different threads about various screen concerns, but this one is specific to color distribution. Sorry if this belongs elsewhere.
I attached a picture of the Note 3 screen without any screen protector while on the dark gray color from the LCD Pixel Testing app. Apologies that the uploaded picture isn't rotated properly. The bottom-right has a purplish/pink tint to it and the top-left has a greenish tint. It's not the camera angle/picture because I took another picture of it from the same angle, but upside down and the coloring moved accordingly.
I also took a picture of the Note 2 under the same conditions to make sure that this isn't normal for other screens, and the Note 2's screen was much more consistent. I've experienced uneven color distribution on the Samsung UN46B8000 TV, but not on a mobile device.
Does anyone else have this type of uneven screen color on the Note 3?
Thank you!

Im not sure why is this happening. Im now on my third replacement and every one has this hue or tint in different parts of the screen. Im not sure if its fixable but I gave up on samsung. I just hope it goes away after some time.

Thanks for the reply. I'm going to check out display models and see how the uniformity is. If they are worse than mine, I'll keep mine. Still, I think that Samsung should really work on this. I've compared it to the Note 2 and S3. All have better uniformity than the Note 3, which saddens me as I was really looking forward to this device.

EXACTLY.
The exact same problem with mine, which I described here in my thread.
I've seen worst when I tried to get my second replacement, so I decided to keep mine.
SAMMY whats wrong with your QC????

I spoke to one of the tech guys at my work and he said it could be a power issue. The power source could be coming from the upper-left corner and it gets weaker as it goes across the screen, which could explain the gradient-like change in the display. If the pink is at the bottom-right for all our displays, it could be the explanation.
We looked online for a proper teardown, but we couldn't find one that showed where the screen power originates from. I don't know about this because I'm not sure if full/more power would result in a greenish-blue hue. The only evidence I can think of that supports this is that the Note 2 and S3 were overly greenish-blue in tint over the entire screen.
Does everyone affected have greenish-blue on the top-left that fades into pink on the bottom-right?

just tested mine with the app i got no tint or diffrent hue .. I've tested it on AUTO, Manual low, high brightness settings..

I have these problems since I own AMOLED devices, and that is now for quite some time (see sig.)! Me too had to exchange each device a few times until I got some with a almost perfect screen! On both N9005 I own so far the lower screen side is darker, although there are other significant differences between the two screens: the one of the second device is much more uniform! plus no1 has sharp pitch up in gamma on the leftmost 5mm over the whole side (maybe this screen has been cut out from the edge of the mother-substrate: the more from the center the better, due to principles of metal mask lithography)
I've done a few posts in regard to this in the past, if interested use the search function!

Another problem I have: When CUP is on medium to heavy load, screen brightness and contrast start to go up and down slightly each few seconds on all brightness levels, even on manual and lowest brightness! this happens on both devices, although here the first one is a little more stable! for me this happens always when in gallery for example, due to CPU load because of media scanning... Seems to be some load or thermal brightness throttling mechanism implemented (guess: in some part of the kernel)...

mine doesn't have a hue but on really dark colors (like the dark tapatalk theme) the screen color is uneven on the background.

I'm happy for you. For me, I gave up and bought LG g2 and I'm so glad I did. I just love this ips screen.

I'm wondering if it's there is edge LED lighting and the screen is just uneven.

My first one was like yours which seems very bad. Took it back got a new one, this one has the issue too, but its not that visible. I wanted to take it back again, but then i saw a guy who took 3 Note 3s back and the last one was the worst. So change it until you find one acceptable and next time wait a bit until Samsung gets better QC, or hope for another player on the phablet market.

???edge led on an amoled device???
do you know what you are talking about??

amoled is common in that type of tint.. I used all galaxy. Since first galaxy I used.. And now still smiled tech have this tint..

It's probably not as bad as I make it sound. You can only see it if there isn't any light in the room basically. I took a screen shot of the battery status menu and cropped it to the all "black" part and put a black dot on it. In a totally dark room (doesn't mater what the screen brightness is) see if you can find the dot. It's pretty small you have to zoom in a lot. But using this image I can see the uneven lighting on the screen. If there us ant kind of color displayed though it's totally invisible.
I'm kind of worried about getting one that's worse too. that's what's got me not wanting to deal with it. A lot of them down here have been getting returned to best buy and Verizon because of a signal issue or battery drainage problems.

Nope. Obviously. ?

So I returned the first one and got another. This one is better but there's a big dark band that goes across the middle. It's not as pronounced as the last one though. -__-

Try this in a dark room. Using Display Tester app test card Grey #808080 and put the brightness in the screen tester to as low as possible as well as your phones brightness to low as feasibly possible. The check out the lower half near the home button. You will see it being slightly different and darker. Both mine and the wife's do it. Her's possibly a little bit more pronounced than mine. Normal, as I never notice it during day to day or night time viewing. Point being I have to go out of my way to find this so called issue.

i had same issue i replaced 3 note 3s then in white color there is no tint no screen issue..n checked 6 phones on shop..u r lucky if u get 1 phone with gud screen among ten phones..9 will be faulty and one will be gud....but my shop keeper is a nice guy..but really samsung should fix this issue.
..
people will complain about hardware issue after some time..when they will compare note 3 together..
coz i have too much experienced in note 3 replacement.
i had three note 3s n900 and n9005.And checked 6 note 3s...so trust me..some device perform gud some laggy..

can confirm this! and it was the same on note1, note2, ... on basically all amoled devices i owned from samsung so far!
the "problem" is the manufacturing process of the amoled screens:
they were cut out of a wafer. in the process of exposing the wafer with a light source through a FMM (fine metal mask) the exposure is not evenly distributed over the whole wafer. the more from the middle your screen has been cut out, the better it is! the gradients (down side darker, right side darker, ...) are due to the gradient light exposure of the wafer before cutting!
so it's all luck of the draw: atm i have one (!) decent screen out of 5 devices! the bad thing is: on this device the thermal throttling is comparable worse then on two of the other devices i have, but on these the display is very uneven!
so it seems to be a hard task to get a device where a) the screen is perfect and b) there are none of the other known problems (wobbly button, thermal throttling, noisy camera, ...) present!
thank you samsung!
