Purple tint

Anybody got this? In low brightness some darker elements(specially gray) start become a little purplish
Also the colors seem less saturated in the default screen mode than the s3(also in standard) i thought i would be the opposite, is my screen defective or is this normal
I tried google but all i get are galaxy nexus results(purple tint)

Welcome to S4. Every galaxy S4 has this. Please refer to other threads on how to get rid of this smearing through software.

The OP doesn't mention smearing.
This is a different issue to the smearing problem.
When the brightness is on low greys become purple. I have had 4 different S4s (all had to be replaced due to screen issues) and every single one had this problem on low brightness.
IMO there is no such thing as a perfect S4 screen!
I have finally settled on my 4th replacement and this one is still not great but I'm sick of returning them.
I have a pink tint at the top of this screen and also all the sensors, LED and front camera are misaligned in the casing, All over to the left.
Samsung have REALLY failed on the Quality Control of this device.

So it seems universal, well i will have to turn off auto brightness and use brightness at 30%
Any of u guys came from the s3? Do the s4 colors seem a little less saturated to u guys? I have them both side by side and it seems so

Yes. I had s3 before and the less saturation on S4 is intentional by Samsung. According to some detailed comparison, the colors of s4 are more accurate. It seems odd at first because our eyes are used to the oversatured screen of s3.

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??
:'(

My s4 has the same issue. A pink tint on the botton. This is my 4° device and no one had a perfect screen. Samsung quality control really is a crap.

yes its normal to happen in amoleds. I have 2 devices with this same tint issue. Just ignore it and enjoy your device unless its really visible in daily usage.

send it back for repairs or replacement?

I dont know.. if its normal then I think why need to give for repair...
Its not annoy me.. its very very less tint.. I think it wont noticed much after changing viewing angle. .. I was just worried about that's why was questioning that its normal?
Waiting for more replies keeps that it's normal. It will make happy..
Seems like silly right?

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?

I think is normal. My current device have a pink tint on the botton. To be thinking or searching to see this issues is not good for us. We need to forget it and enjoy our devices! Best Regards!
And sorry my bad English again.

Seconded.
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.)

Could someone with a Note 3 check this

Thinking of buying the Note 3 but really wanna know how bad the smearing issue is cause i bought the Galaxy s4 on launch day and couldn't live with the smearing issue ( my girlfriend also bought a Galaxy s4 on launch day and still has it..she didn't think the smearing was annoying..i hated it )
Could someone with a Note 3 try both things explained below on low brightness
1. Download zedge and search for black wallpapers..then while scrolling thru the wallpapers..do you so smearing..purple glow on the grey background in zedge between the wallpapers?
2. Choose a black wallpaper as background and install nova launcher...then on the homescreen set a widget with some grey in it like the stock music player widget and scroll between the homescreens...and also with some icons on the homescreens?
On the Galaxy s4 doing the above there was a lot of smearing..purple glow visible even after the fix from samsung cause they only fixt it in the samsung framework

I tested Zedge.. Yes there is smearing.
But when you uncheck Auto Brightness Smearing is much much better.
Auto Mode is very dark. In a dark room it gets darker again..I recommend manual Brightness 30 - 50%. Then its really fine.

The purple smearing effect is probably just because the greys blur when moving and they appear purple. Entirely normal and probably same on all phones.

Jep. Black = Pixels are off
When you Scroll the Pixels need Time to activate. Thats the Price for real Black

^^ Ditto, I don't find it annoying, I didn't even know about it until the OP mentioned it.

Ive seen it in Tapatalk 2 with blue dark theme..
Black background and gray Text..The complete Text smeared..
Now i use the classic dark theme (dark grey background) and all is fine
Dont think about Smearing.. i think you will just see it in darker rooms.

Thanks a lot guys...you saved me 750 bucks, some people don't find it that big of a issue like my girlfriend who still has the Galaxy s4...for me it is an issue cause i like to have a black background and while using a black background with nova launcher..on my Galaxy s4 the smearing issue was visible on the icons switching thru the homescreens..don't want that on my next phone

Had the Note 2 and there the smearing was not present cause while displaying black the lights where still active. Bought the Galaxy s4 on launch day and that was the first time i had the smearing issue cause when displaying black the amoled screen is really off so when switching to another color like grey the lights need to become active witch creates the smearing. Sold the Galaxy s4 and bought the htc One that has no smearing but wanted a larger screen so bought a Note 2 again witch has no smearing issues cause the screen doesn't turn of like the Galaxy s4 when displaying black and hoped the Note 3 wouldn't have it but seems it does unfortunatly

OR you could've installed one simple app that would've fixed your smearing issue on your S4. Your blacks will not turn off completely and will remove smearing 100%.

No problem though cause after the galaxy s1..s2..s3..s4 and note 1 and 2 it's time to give someone else a try

Screen quality, yellow tint?

Hi
Currently got an S4 and I'm looking to replace it as I use it a lot for movie watching and magazine reading and the slight yellow tint to the s4 screen really annoys me.
Seeing as the note 3 has a similar screen, but just slightly larger, can people confirm whether the note 3 suffers the same inaccurate whites/yellow tint?
Thanks!
Sent from my GT-I9505 using xda app-developers app

I don't know what yellow tint you're talking about but my S4 didn't have it nor does my N3. I dont use adapt display and my screen mode is set to dynamic
Sent from my SM-N900W8 using Tapatalk 4

It's when viewing whites my s4 has a decidedly warm colour to it so whites look dirty and slightly yellowy. It's a well reported characteristic of the s4 although probably didn't affect every single one.
Just want to know if the note 3 solves this by having cool whites as opposed to warm. Maybe personal preference but I much prefer a cooler display.
Sent from my GT-I9505 using xda app-developers app

I have noted it but just in the movie mode, in dynamic and standard it seems a little bluer to me but it's personal opinion. But I have to say damn this is a beautiful display worth the choice of the phone by itself
Sent from my SM-N900 using xda app-developers app

That's good. As long as some of the modes have a cooler tint I'll be happy. The green/yellow tinge is just a bugbear of mine.
Thanks for the replies.
