I think that he meant this:

I dont think he is refering to both yellowish screens or banding.
I'm having this issue too. It doesnt show itself unless the screen brightness is turned down, and especially an grey background. There will be faint large vertical stripes. It is as if the backlighting is uneven. Increase the brightness and it'll go away.
Seeing that i do not have the yellowish screen problem, no stuck/dead pixels and no bluish tint problem, im very reluctant to send this phone back for a replacement due to this problem. Its something that i can live with.
Hi
Just wondered if the Screen Adjuster app poses any risk of damaging the S4 screen after a while? My phone has a noticeable yellowy green tint which makes photos and videos appear slightly green. I downloaded the Screen Adjuster app which lets you adjust the red green and blue sliders and it reduces the yellow tint (although it doesn't work when playing videos annoyingly).
I have seen on other similar apps the developer putting a warning not to use the colour slider tints on OLED screens as it damages them, so I just wondered if I always have the Screen Adjuster switched on whether I am damaging my screen in the long run?
Hello, I think my HD2 have screen bleeding. When i'm outdoor, I have hard time to see anything on display & there is a three white bright dots on display. Can I fix this problem or I need to replace display and digitizer ?
display is quite bad in outdoor bright sunlight so that maybe normal, white dots sound like maybe dead pixels.
Try posting some images of it if you can.
Also look at backlight setting for brightness & see if adjustment seems to work correctly as maybe have issue with LCD backlight !
Like you already are thinking, LCD is needed but some images would be good to confirm this & I would not re-use the current digitizer unless recently replaced & removed without any damage.
Can anyone make an ultimate fix for galaxy s4 smearing?
Are you talking about the graphical smearing/tearing that happens when you, for example, scroll?
This is caused by the pixels. In AMOLED devices, when a pixel shows black, it is actually turned off. However, there is a delay when turning that pixel back on. So if pixels have to change from black to colored and vice versa (for example, scrolling through your app drawer if it has a black background), this graphical glitch occurs because of the delay from turning the pixels off and on.
Samsung has rectified this issue on their stock ROMs by eliminating true black, making the pixels always on. This will also negate the battery saving effects of AMOLED displays when showing black. This is the only way I know to fix the problem.
If you were referring to another "smearing" please elaborate and we may be able to help better.
I'm talking about that one that you said.. but in 3rd part apps in 4.3 stock android roms there isn't any fix ,apart Screen adjuster setting contrast -10, i wanted to know if someone can change blacks in very dark grey keeping the other colors , not changing all the colors setting contrast -10 or SmearFix app

I just brought a yotaphone 2 and notice the screen (color side) will change to red/purple in color (especially the dark color area , like the black one) when i set the brightness to a low level(below 30%)
is it normal issue to all amoled display??
this is my 1st time to use amoled phone
nope, it could be damaged during transport. check if yellow spots appear, that's usually the sign of damage. nothing to worry about, it's just annoying
It is normal - if you are in dark and you lower brightness less than 20% it gets purple.
