Yellow Tint

So on low brightness the whites seem a bit yellow. Can anyone confirm this?

Its a common problem, at 0% brightness white is a tad yellow but still its much better than having blue/green or pink tint.I've tested lots of S3's in various stores all shows same phenomenon so getting your set swapped wont solve any purpose.

Well even at high brightness settings it looks a bit yellow. When I tilt the phone it looks more white and when I tilt it back you can clearly see the white is a bit yellow.

Yes its a "Bit" yellow on low brightness but on high brightness mine is pure white, its common with AMOLED they are unable to attain LCD whites.However this doesn't bother me much because I'm used to it now, keep in mind its not an tint screen is tuned bit warmer.
Ahh so it isn't just me

You bet!
Well.. It even seems to be a pretty pink compared to the GS Plus. Both at full brightness.
Sent from my GT-I9100 using XDA
I think it's configured this way because blue pixels expire the quickest in amoled screens </not expert opinion>.
In either case, past phones have been able to use color controls like supercurio's app to change the tint. (And, by then you might've gotten used to it anyway.)

Does it matter which screen setting you have enabled in the Settings app or is it on all of them?

Stop comparing displays and enjoy your S3.

Not as bright as my s3 fault or needs tweeking

Love the note it is fantastic , I have one minor complaint the brightness is no where near as bright as the s3
I'm not sure if this is normal , is a fault or something needs tweaking
I'm in full brightness , auto brightness is off and so is adjust screen tone
Is it just me ?

Did you change the brightness in the drop down menu only?
That slider is just a fine tune for the actual setting.
Go into settings and display, and there is a REAL brightness slider there.
Note 2 is supposed to be brighter 450nit vs 350nit $3
Sent from my GT-I9300 using xda premium
Interesting. Could this be due to lack of consistency in manufacturing? GSMArena said that their review unit is less bright than the one they previewed.
My device is bright enough.No problem at all under sunny conditions.
Hey guys, I think we all confused about what the real question is, i mean my NOTE 2 is bright enough too. but I think what he means is, the quality not the brightness. Honestly I have the same problem, when I compare my s3 to my note2, the s3 the color is more alive, for example, when you look at the icons in your desktop is not NEAT as the s3. When I had my s3 I faced the same problem, what i did was change my ROM but in this case, we have to wait until they release more rom for the note2.

[Q Many white dots on the screen

Hi all, i have bought 2 nexus 4 and they have many white dots around status bar when i use "lcd test ( amoled ready)" . It can be seen with a very very small angle and on white screen with full brightness . Is it ok ?? I'm very worried about it . Thanks all and sorry for my bad English

If it bothers you or gets worse, return them under warranty? You probably won't notice that anyway under normal usage.
Maybe the lcd settles in a couple of weeks and they disappear!

[Q] quick feedback needed on pink tint on screen

need some fast feedback on this. Last night I noted that the top left part of the screen is less bright on 0 brightness In my bed room, with careful monitoring it looks like I have pink gradient on the top part of the screen at zero brightness. Do any of you guys have this pink tint issue on top of the screen? This can be noted only in dark room with zero brightness, also with zero brightness the whole screen looks a bit pinkish but it totally vanishes once the screen brightness is increased from 0.
This issue is totally unrelated to smearing or red pixel issue afaik.
I need some opinion regarding this guys.
Sent from my GT-I9500 using Tapatalk 2
At 0 brightness my screen also displays a pink tint on white.
When brightness is raised the tint gets lesser
That's nice to hear, I have a chance to replace my device today, hence I'm making sure that I'm not doing something wrong. @Obagleyfreer
What about the pink on the top part of the screen? Can you reproduce it?

My device shows pink at the top left and also slightly all across the bottom.
This is only on very low brightness in a very dark room. Normal usage it's not noticeable
It will be good to know if your replacement device has it also. This is actually my second Galaxy S4. I returned my first after 2 days as there were 2 lighter stripes running horizontally across the screen on grey and white at lowest brightness!
My advice to you is to take the phone into a dark cupboard in the shop and double check everything! lol
The trouble with AMOLED, as I'm sure you're aware, is that you can replace a screen with 1 problem and get another problem on the new one.
Which is why I settled with my slight pink tint at low brightness screen lol
Good luck!
I also get very slight pink tint on black in dark room, but it looks pure black I am normal light. Should we be replacing or not?

but with screen adjuster the smearing in almost fixed, as of no way to fix red pixels issue unless an sw update is issued.
some people with smearing issue got red pixel issue after a firmware update right?
btw the purpose of replacement is served.. the pink tint issue is now no more
Will be interesting to know if you get screen smearing after updating. Keep s in the loop dude!

Hey Bala,
Yes i will develop provide my replacement device that's on the way has no pink tint issue
Its funny we shell 40k for a device and then we send it for replacement and have to wate another 7days, since i bought from ebay now i have shell our money to ship the device back also
I am giving samsung one more chance if the replace ment has the same issue i am going to buy a HTC One!
Also bala can u tell me which batch ur S4 is from, i got a Veitnam built s4 manufacturing date was may 2013

S4 amoled screen also mura effect?

My phone is 1 month old..
And now I m noticing that there is blue shade on 3-4% part of the screen at bottom in 3-5% opacity...only in 0% brightness.. it wont shows in more than 20% brightness-100...
Its very slightly difference..
I shown my device to my near service centre.. they said there is nothing and its normal..
Screen not looks like that its defected piece.. bcuz its not high opacity shade..
Its hardly feels that its 3-4% opacity or(96% transparent..)
Its not much noticable. If we look closer then still not much noticable.. its very very slightly tint..
I was happy with s4 but now I m worried because I spend hard earned cash 40k on my device.. and I dont want hear that my device is faulty.. :'(
I used s3 and note 2.. and s4 has this too.. not much improvement from s3 and s4 displays..
so, is that normal??

The issue that your device have appear very discret. I got a unit that the screen was terrible. Whites was yellowish and when the device was inclined a very visible green tint appears on whites. The problem is you replace your s4 and to get a baddest. Sorry my bad English.

Yes.. thats why I worried..
Btw I shown my device to service guys they said its normal.. they said "where is tint" I think they dont want to notice..
But as I said.. its not noticable.. I have tint at bottom 3% part of screen which is very less.. new person after holding my device, he cant detect that tint..
I have not tint in all screen like u said yellow or bluish on side..
Mine is not noticable but it has tint below which pretty much less opacity for eg. 2-3% out of 100..
Just wana know ia it normal..? Is it in all amoled screens? Is that tint, we should count it as defect?

If it doesn't hinder your usage of your phone, then just enjoy the screen for the excellent colours etcetera. I'd say a lot of these phones will have a similar issue (or non issue depending on what way you look at it.)
