[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.

Color temp

Hey guys, does anyone know if there is an option to change the color temp of the screen? I remember hearing the sgs2 had a feature to change it built-in. The color temp is a little too warm in my opinion. It might be on purpose to conserve battery but I would prefer it to be cooler (the whites are too yellow).

On my SGS2 I had an app called Screen Adjuster. It would let you change RGB settings. That might help, if it works with ICS. Other than that I know some ROMs for the SGS2 had different screen "modes" like Dynamic, Movie, etc.

Did the app work well for you? I'll give it shot man, thx.

On the SGS2 it worked amazingly well. Made the colors less saturated and more realistic. Of course, that's with the SAMOLED+ screen I think. I'm not sure how it will work with the Nexus screen. Different technologies, right? If you search the SGS2 threads for "screen adjuster" you can see some people's recommended settings for the SGS2. Maybe you can use that as a starting point and work from there? Good luck.

Yea I'm not sure how it'll react since the nexus uses a pentile arrangement while the sgs2 uses rgb. I've actually gotten used to it and don't mind it at all now. Haha go figure right. I guess my eyes just needed to adjust from switching from my vibrant with voodoo color which looked noticeably cooler.

Sorry to resurrect a dead thread, but I thought it was worth nothing that I tried the Screen Adjuster app, and while it worked for adjusting the calibration/color temp of my screen, it seemed to make my phone VERY laggy. Does anyone know of another app that will do the same thing but apply the settings permanently in some way without having the run the app in the background? Maybe with root?

"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

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.

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.

How to dim the GN screen even more?

I find the dimmest screen toggle still too bright. I find it embarrassing to use in dark public spaces.
Is there a way to dim the screen even more?

Download the screen filter app from the play store. Literally puts a filter effect on the screen to make it appear darker making it much easier to use in the dark.

Yes its possible to take the screen much lower, but we have to edit the framework. Nobody had done this mod yet for some reason.

CM9 has the ability to change the screen lowest settings built in

+1. I use Screen Filter also, it's uber handy for reading at night when the light seems too bright. If you've got hardkeys like I had on my Desire, you can even turn them off.

i wrote a tutorial on how you can mod the frameworks apk. it's very easy and you can change the brightness levels to anything you want. here's the thread
screen filter only puts a transparent layer on the screen and messes with the colors. modding the frameworks will lower default brightness to any level you want. you can raise it too if you like.

Thanks for all the ideas. I went with the easiest one, Screen Filter.

AOKP also has an option to reduce screen brightness...

Great work, I've been wondering why nobody did this mod yet for the nexus. I made that same mod on my atrix, using the sgs2 thread as well. But I've been too lazy to do it for nexus.
The above mod is the best option. Screen filter doesn't achieve the same results. The above mod reduces power draw as well when on the lower brightness setting of 5 or so. Screen filter just hides the higher brightness but has same power draw.

That would be correct for back-lit screens. For the Galaxy Nexus screen, though, Screen Filter does help reducing power draw as a darker screen content = lower brightness.
I used to use SF for quite a while until I got fed up of it causing stutters to most animations. After thorough examination I concluded that the Nexus's GPU is the culprit. For some reason it just doesn't like multiple graphics being updated at once. Modding the overlay XML allows it to run at full speed.
Can anyone confirm the same reduced framerate issue?. It's also the reason why some ROMs include a setting to remove the navigation buttons glow. I tested with CM9 on the SGS2 and experienced none of the stutters in cases where the GN would. Another example: sliding between sections (comments, ralated, etc.) in YouTube is laggy iff the video is playing.

Agreed, GPU just isn't good enough. I hate the lag with the button glow animations on!
I use an app called root dim, it's really useful. Let's you use a brightness level of 1, which is really quite dim. Free, too.

Thanks for the tip, on the Galaxy Nexus it's possible to set the brightness to 0 by writing to /sys/class/backlight/*/brightness but the brightness is checked and reset to the minimum (default 10) every time the screen is turned on. I guess Root Dim works to the same effect so it runs as a system service. Still, it'd be an awesome addition for people who haven't bothered to mod.

Screen filter may reduce power. But amoled screens save power with lower brightness. There is no difference between lcd vs led on this issue. And modifying the framework to bring min brightness down to 5 rather than 15 saves much more power than screen filter. Its no contest. This isn't different from lcd in this case.

Yes we can write to that sysfs file, but it gets reset. The mod to the frameworks incorporates that backlight file so its now able to go down to 1, 2, 5, or whatever you want. It makes it now stock, so you are no longer capped at 10 (actually I think 15 is the cap I see). But that mod is just removing this cap and making it lower to whatever you want. Stock.
So no extra app is needed. No additional tweak. It now makes the stock brightness able to go down to 1 by itself whenever it needs.

Brightness issue

First things first, i want to APOLOGIZE if this is a repost as i haven't been able to find this issue else where unless im just that blind.

9-20120724 nightly.
When brightness is set to max, and auto brightness is turned off the following happends.
Overall brightness seems a little dimm, not a whole lot but enough to notice, however when i slide the notification slider down the bottom of the screen gets brighter, also when in email or messaging app, when the keyboard is open the top half of the screen become brighter, were talking about about 10-15%
Is there a setting i can modify in a file that represents the overall total allowable brightness, i just figure if the screen becomes brighter under certan circumstances then it might be possible?
Also the color almost seems a little be off, like white is not quite white. Annoying for extended reading sessions.
tried changing the mDNIe settings but nothing changes.

Really? Mine does the same thing. I figured it was the ROM cause stock I haven't noticed it. My HD2 did it as well. I honestly think it has something to do with battery saving. I noticed if there is a lot of white showing it dims it a little, then when there is a dark image, it increases the brightness.
