[Q] Samsung Focus: Hack to Disable Screen Dim on all White Screens (like Email)

Is there currently a hack, custom ROM, or other way to prevent the screen from dimming way down when on screens with lots of white (like the email/Outlook screen). Even when I have brightness set to "HIGH" and Auto to "OFF", all the other screens are really bright. But when I go to the email screen (or any other app that has a white background), the Focus automatically dims it way down. I'm sure this is to save battery or eye-strain on white screens, but I'd like it to be much brighter if possible.
Thanks!

Yeah, It's look hard but I want it on my HD7 too.
because the auto-brightness on WP7 was not smart so much compare to the other.
It's not give the lowest brightness when enter into the dark room (that's hurt my eye) and not bright enough when enter into the sunlight.

Nope. It's programmed into the pentile display driver. Total deal-breaker for me.

The auto-brightness setting in WP7 adjusts a screen's brightness based only on the ambient light sensor. The Focus and Omnia 7 dim their screen if they're displaying a majority of white pixels, even with auto-brightness off and set to high.

Switch to the white theme. It happens so frequetly now that I don't even register it!
OK, so that's not a solution but give it a go, it bugged the hell out of me at the start but now ive forgotten it even does it.
I understand why they've done it, but really it should follow the brightness setting if they're worked about battery life.

Camera options

There's a couple of options in the camera app that aren't entirely self-explanatory. Anyone able to shed any light?
Anti-shake: The manual says, "reduces image blur due to the movement of the subject of the photo or hand movement." Any ideas why this is disabled by default? Are there any downsides to reducing shake?
Auto contrast: The manual says, "provides a clear image even under backlight circumstances where intensity of illumination can vary excessively." Does anyone have any idea what this is doing? Is this HDR?
Outdoor visibility: The manual says, "allows you to take better pictures when outdoors." Anyone know if this does anything besides just make the screen colors brighter?

Anyone have any ideas?

Anti-Shake is an option to use to help reduce the effects of the camera moving while shooting a picture. I see no downsides to enabling it unless you like blurry pictures. It might reduce battery life a tiny bit more while using the camera.
Think of it as mouse smoothing in games, if you do that sort of thing.
Auto contrast is a nice feature (if it works well) that adjusts the pictures light levels in case of a dark subject and a bright background, or vice versa. It should help to make a better overal balanced picture.
Outdoor visibility has to do with the LCD screen itself. If you are outside on a bright day you want that on. It makes sure the backlight is on full and the colors are bright so you can more easily see the screen.

ScreenDim

New on the Market:
https://market.android.com/details?...mkub21lZ2FjZW50YXVyaS5TY3JlZW5EaW0uVHJpYWwiXQ..
"Is your minimum screen brightness still too bright? Dim your screen below what your device normally permits for comfortable use in darker environments, reading in bed, amateur astronomy, etc.! No root required."
I find this app indispensable for comfortable reading at night.

Thank you so much for this, I was just thinking last night that even the dimmest setting on the A100 was still to bright

Brilliant find, normally use the Kindle when reading in bed but the web browser is diabolical.

I'm the ScreenDim developer. Screen Filter is free and clever, but it doesn't do the same thing as ScreenDim, at least not on LCD devices. Screen Filter basically just alpha-blends a dark box over the screen, without lowering the backlight level below what the OS normally allows. The result is that Screen Filter lowers the contrast and the color resolution, and in a dark room, the blacks will be gray because of the backlight shining through them.
ScreenDim allows you to both lower the LCD backlight level below what the OS normally allows on many devices and, if that's not good enough, to control the contrast just as Screen Filter does. Furthermore, because ScreenDim allows you to lower the backlight level, it will save on batteries in a way in which Screen Filter will not, again on LCD devices. (On OLED devices, there is much less of a difference.)
Moreover, my testing on my Archos 43 indicates that Screen Filter lowers the 2D rendering performance by about 30%. ScreenDim at 100% contrast shouldn't affect the 2D rendering, and even with the contrast adjust, I couldn't measure a noticeable 2D performance loss.
For real free alternatives to ScreenDim on backlit devices, there are AdjBrightness and my RootDim, both in the Market. Both require root, however. And ScreenDim's dual brightness-contrast adjustment feature is found in neither.

+1 for root dim, I use it and it works well on this tab and my atrix

be careful not to set it to 1 because its turns off the screen but the tablet is still on. i got stuck trying to find the slider to slide it back so i can see the screen again. nice find though.

Tapping random places on the screen should quickly restore the brightness.
Also, if the tablet has volume buttons, you can adjust brightness with them.
Once you figure out what the lowest you can go is, go to Options | Set minimum brightness. Then you won't have this worry any more.

screen filter
Love screen filter it works great and its free, super simple, plus pop notification bar too. Awesome app. Screen filter is

ahem. I'm not sure exactly where those buttons were when I needed them to try to get the brightness restored, but I couldn't find them on two occasions. I had to hard power off.
Great idea but it won't work for me unfortunately. I want something that will turn my tablet into pure darkness except for a small, dimly illuminated, clock on the screen. No matter what I find, an app always has too much backlight on and it bothers me when I'm trying to sleep.
If only I could get this app to interact with my alarm clock app somehow!

Status bar
Is there any way to remove the status bar icon of the ScreenDim?
I thought the app was designed to reduce distraction while using a device, but the icon being in the most prominent spot (upper left corner) draws attention constantly.

Auto Color and Sharpness based on enrivonment luminosity

So, I noticed the screen changes its colors and text sharpness based on the environment clarity. Altough this seems a nice feature for using the phone on sunny days, the effect brings a strange oversharpened effect on the screen text. Not really a big deal, but I don't like it much.
Is there a way we can disable this feature? I've already tried going into "Settings > Display > Contrast & colors" and changing to "Standard", which should keep the contrast constant, but it seems the option isn't really working. I've restarted the phone and it keeps changing the colors and sharpness.
I made a video for you to understand what I'm talking about.

Thats samsung super amoled boosting brightness nits to increase readability,and its normal, it does happen in all super amoled screens including samsung note 8 and etc.
So it cannot be disabled as far as i know its in firmware of display.
But when you are in direct sunlight i think sharpness or color dissortion is not much of a sacrifice to increase readability.
Would it be better if you wouldnt be able to read whats on display ? dont think so.

For a second i thought my display was faulty but then realized its only for better readability. Not that I particularly like this but the sacrifice is worth it. For now haven't seen a toggle for it yet, but I hope xiaomi gives it in the next update.

Are you sure it is a feature of the display itself? Cause the brightness remain constant, what changes are the colors (contrast actually) and the sharpness...
And yea, like I said, it isn't a big of an issue, I just wanted to have control over it, but I can live with it haha.

I had this on my Galaxy S9+ and somewhat annoying under sunlight, though not as noticeable as on Mi 9 SE because of higher resolution and DPI. The only way to deal with it on my S9+ is turn off auto brightness and slide the brightness down to a manageable/readeable level.

Well my auto brightness on the mi 9 se is already turned off, and this keeps happening, so its actually unrelated to the brightness, more like a separate feature.

How to turn off adaptive display? White balance and RGB settings not working?

Does anyone know how to turn off the s20's adaptive display feature? (I'm not asking about adaptive brightness.) I'm on a US snapdragon, unlocked, regular S20. Thanks!
I am referring to:
"Samsung's adaptive super AMOLED screen optimizes the color range, saturation, and sharpness of the picture depending on what you're watching or doing."
https://www.samsung.com/us/support/answer/ANS00063051/
The vivid/natural, white balance, and advanced RGB settings mentioned in that link do NOT seem to impact the adaptive display feature. (And in fact, white balance and RGB settings don't seem to do anything at all... If anyone has thoughts about why THAT is, or how to make them actually have an effect, I'm interested.)
I have tried turning off dark mode completely, turning off the video enhancer, and turning off the dark mode on wallpaper, but the problem persists and impacts things like apps and pages in Chrome - basically everything.
If I look at my task switcher, app screens will often look the way I want them to in the preview, but when I click on one, after about a second the display adjusts and changes the image to something brighter, whiter, and less what I want. This is true whether adaptive brightness is on OR off.
I'm trying to use a screen filter to manually set the screen to the settings I need, and it feels like the screen is fighting the filter and countering it, and I think this business with the adaptive display optimizing color and saturation could be the problem. Or if you have other ideas for the source of the problem, I want to hear them.
Any help is appreciated!

they removed the option to close adaptive display since Note 9 starting from s10 it is always on and can't be disabled

It was something like attached picture on Note 9

Ah hah! I think I figured out a solution to my problem (which was that the whites were too blue and bright and vivid as compared to everything else on the screen, no matter what settings I used on Twilight or another screen filtering app). For anyone who comes after me with a similar issue: the native blue light filter doesn't JUST turn on/off - it has an opacity setting which you can find and adjust by clicking on "blue light filter" in your display settings menu, to the left of the on/off toggle switch. Turning it all the way up (to the right) tones down the whites and blues without impacting the rest of the colors on the screen, which for me at least creates a much better color display ratio.
