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

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

A way to reduce backlight brightness beyond default settings?

Hi peoples
Does anybody know of a way of reducing the backlight brightness below the stock settings?
I've tried various screen filters, such haxor Screen Filter, but these apps are rubbish IMO. All they do is apply a grey transparency filter over the screen, they don't actually reduce the backlight brightness The result is a trick, the screen looks darker but it's really only because the white pixels are made grey. The problem with this approach is that it messes up the contrast and colors, and gives a washed out look.
I like to sometimes use my N10 in a pitch black room, which needs a very dark screen. My old Galaxy Tab 8.9 was good for this, because the backlight was able to go much darker than the N10. The thing is, I know the N10 hardware is capable of having a darker backlight because if you don't touch the tablet for a few minutes, the screen first goes dim before it turns off.
I would like to be able to manually activate the very dim screen setting, or better still, have a lower brightness range available in the brightness settings.

[Q] hardware or software issue?

hello everyone
i received my snapdragon note 3 yesterday, was playing with it till i found something, its hard to explain but i will do my best.
what i noticed is that when i move something blue (like the small bars between each alphabet in contacts) to a black space (where pixels are shut off), the blue bar turns purple for like quarter of a second and then goes back to its original color.
it is really bothering me, i waited like a month to get the snapdragon version from outside my country and now this is happening.
could it be software issue? as i remember that note 1 has a display issue where black color appear grayish in homescreen, if so, what are the best stock roms that support RDLV root with out tripping knox ? last thing to note is that it is really hard for me to return it to where it came from.
any help appreciated.
edit: it apear that it is happening with the gray color or any other one that tend to be grayish at very low brightness

This is something you'll either have to get used to and learn to live with, or sell the device. It's a HARDWARE issue, not software, and it can never be "fixed" in any way. The short explanation:
What you are seeing is the latency inherent to the design of the AMOLED pixel matrix. It takes some time for the pixels to go from black (off) to any other color (on) and what you perceive as a blur or "small bars" before it does so is this latency, and when you are driving so many pixels on a full-HD display, the latency is even more apparent.
Samsung has attempted to mask this design limitation by essentially taking true black (off) away from the user, but it only works for Samsung apps and the parts of the OS that are tied to the Touchwiz UI.
update:
it appears that this problem is called smearing/ghosting, the reason it happen is that samsung made pixels combletly turn off when it is black in addition to cutting any power going to the screen.
why Samsung did this? well, to fix something called mura effect (black amoled screen can be seen as green or brown in very dark room), this caused a delay in turning on the pixels again which caused this effect (especially with gray color).
the solution is to use an app called screen adjuster (found for free in play store) and using the following setting:
red +14
green +14
blue +14
brightness 100
contrast 0
hope this help anyone who encounter this problem
cheers

as i said in the post above, i managed to solve it but adjusting screen colors (a Little bit that it does not affect the overall colors and in the same time keep black pixels on)
by the way, are all note 3 owners facing this issue like what happened to most s4 users or just me?

Just so you know that all you've done to "solve" the problem is shift the colors up to remove black. It's not worth the loss of a true black (off) pixel state, IMO, but to each his own. All Note 3/S4 owners have this issue. Some don't notice it until it's pointed out to them, but it's a hardware/design issue common to every single unit without exception.

This is silly-S10+ screen dimmer/colours in lower brightness (read my post)

Hello there everyone,
My S10+ Exynos variant suddenly started showing wierd colour bad contrast in lower britgthness. When dimming the phone below 40% , the picture/video quality gets so dimm, pale, also i notest at work, my other two coworkers have same phone, with notisably darker picture, pictures and videos are darker , contrast is wasy better between dark and bright parts of the picture. And i know about all settings, vivid, advanced, visibility enhancments, Themes. Tried em all. I know android very well in stock settings.
Also i have tried factory reset, wipe chache, i even F...uking updates the phone to the very last firmware, and each update even after factory reset didnt change anything. Its still the same. At lower brigthness the screen gets so grenish dimmed and pale, colours lack contrast.
And also another wierd thing... in both of my coworkers s10+,s dark mode (night mode from pie) is amoled dark, pixels turned of, on my phone its not, they are turned on, dark grey colour. Funny thing is, if i take screenshots, they are not, screenshot shows amoled dark. While in phone, pixels are turned on, like its backlight lcd panel and not amoled. Screen failure or something else i can do?
Any tweak app or something to play with contrast ratio in Samsung Galaxy s10+?

Gradient in brightness

Has anyone noticed there is a gradient in brightness on the main display of the LG g8x or is it just me and my phone
The best way to notice this is to open any gray background and look at it in landscape mode
yes, Many of them have same problem but it affect only in night time, day time can't find the issue.i don't know whether gradient, uniformity issue are same but my phone have uniformity issue (dark gray background with 0% brightness) bright in top,dark patches in bottom.so I change screen colour to sport and warm temperature better than before screen (reduce only small part of dark patches in bottom ).use dual screen in dark room change the screen colour you may see the difference or may not .uniformity issue also in LG latest oled tv.

Android 11 artifacts and flashing display

I have a blink as well as artifacts at the bottom of the display. Problem is only andorid 11, and some applications Telegram, Messenger and in these settings.
adaptive brightness - off
maximum brightness
resolution-QHD +
theme - white
Do you have such problems?
I think I can see what you mean it's like a little flicker at the bottom?
It's quite subtle, I've not had the issue on any phone ever personally.
Talk to OnePlus maybe for an RMA, also don't use 60hz or QHD.. Lock FHD on 120Hz
Might help.
Yes, and the display flashes.
Unfortunately, that looks like a possible RMA ...
