[REQ]SmearFix - Galaxy S 4 Q&A, Help & Troubleshooting

Can anyone make an ultimate fix for galaxy s4 smearing?

i dont think its possible to fix the smear issue but theres ways to avoid it
it cant be fixed because of the way the s4 screen works, it turns off pixels when youre looking at something black and than it has to activate them once the colors change
to avoid it replace blacks with dark greys

[Q] Colour correction news? (Kernel)

I've been searching the forum for any news on that matter.. haven't found anything.
Any informations on that topic I've missed?
Is it likely that custom kernels will be able to change the colour settings on our N7 in time?
All those different screen calibrations.. Some with more blueish screens, some with more yellowish screens (like mine).
Is it actually a hardware flaw when the screen has a yellowish tint or could that be resolved with custom kernels which are able to mess around with those colour settings?
Sorry to bump, I do know that there's nothing yet. My screen has a yellowish tint too so I am eagerly awaiting this. Anybody got any developments/heard anything?

Should the screen look like this?

My Nexus 4 is under lockdown until Christmas, but I got a chance to have a play with it to make sure everything worked (just incase I had to return it).
I decided to turn the brightness all the way up to see how good the screen was (its GORGEOUS), however, when I was in settings the bottom of the screen is VERY light and it seems to get darker and darker until it gets to the top of the screen.
I turned the Brightness all the way up on my Galaxy Nexus to see of it did the same, and it appears that it does do the same, but not to the same extent as the N4?
Can anyone with a N4 confirm that this is normal behaviour?
Thanks

The settings page is supposed to do that. Its a gradient effect

Perfect, thanks!
What the poster above said.
Harder to notice on the gnex since that amoled display is rather awful at displaying gray gradients .

[REQ]SmearFix

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

Screen color changing? Negative effect?

Has anybody experienced any issue with their screen colors seemingly fading out to create what almost looks like a "negative" effect? It's like it gets very bright and washed out. It's fixed by turning off the screen and turning it back on, but I don't think I should have to do that. Anybody experience anything similar to this?

This I believe happens on Galaxy S5 Mini (I have it) where when it is set to Auto Brightness and I go outside under direct bright sunlight, the screen will boost brightness beyond the manual Maximum setting that you can set. In turn though, the colours on the screen will go psychedelic where things look very bright and washed out. When I go back inside, usually it stayed extremely bright, soI had to put it to sleep then wake it up again to put the psychedelic brightness back into sense.
On the Note 4, I tried this yesterday, colours didn't go crazy, it stayed pretty much spot on, but I still had to put it back to sleep and wake it to fix the brightness.
It's possible I wasn't patient enough to wait for it to return brightness back to normal after leaving direct sun light, but I did give it 10 seconds and it didn't go back.
I got the same experience with my note 4. At the beginning I thought that it was an issue with my screen. But it could be good to know if it is or not. If one day I will get a black broken screen... This issue appears only under the sun light.

Have you tried disabling the "Adjust screen tone" under display settings to see if it has any effect?

its brightness boost happens in bright environment if you close the auto brightness it will be gone. its not an issue. but gets too bright when not needed sometimes. but in direct sunlight where manuel max brightness not enough it helps alot and it doesnt look weird in a situtation like this.

Try blue light filter app from playstore.
Try Screen Burn-in Tool from the Google Play Store. You may have to leave it running for a couple of hours to fix the screen burn-in damage done to your device.
