Screen Backlight ?? - Samsung Galaxy Nexus

Hi
I was wondering if there was an app with which i can turn off the backlight like when u click on clock app and put on desk clock mode by tapping or few secs before the screen goes off ??
is there way to toggle that ?

What exactly do you want to do? turn down brightness when on desk clock? that is already done automatically as far as i can tell.

AMOLED screens don't have a backlight. Each pixel has it's own light source. That's why the blacks are so black, the screen is actually off in black areas.

The clock just makes everything darker. The GN doesn't have a backlight anyway, as it's a (super) amoled screen.

AMOLED/OLED screens also burn when left on the same image for a long period, would not recommend using as a desk clock as stated in OP, you will end up with burnt images where your buttons are, and any other static part of screen

The are a few brightness toggle widgets available, android comes with one built-in, power control allows customization of the brightness level so that you can go say from Max brightness to min brightness in one tap. Rom Control in the Android Open Kang Project allows for adjusting the brightness, order, and number of navigation bar buttons independent of the overall screen brightness.

Controlling the automatic Backlight

Hi,
automatic backlight is still too bright for me in almost any environment. I want to control the brightness of the screen by setting other values.
Is there an app or a hack to do this?
Good question. Loved to know too!
Look under widgets and you will find one called
"Brightness"
I'll let you figure the rest out for yourself

Try to using
Brightenes Level App
I recommend "SwitchPro Widget", which is available from the Marketplace. It allows you to toggle the brightnees, even to levels lower than the automatic setting.
Hi, i dont want to change brightness manually, but want to change the default values which are used for automatic brightness. Is this possible?
Does no one knows??
Hmmm would be handy!

Perhaps you could put some tinted glass/plastic over the sensor, so the phone thinks it's darker than it actually is and doesn't make the screen as bright?

good idea, but that's not the resolution, even in night it's very bright and for me even at manual 1% brightness it's a bit to bright for me...
would be awesome to have more possibilities to work with the amoled screen - by the way - for black it needs 0% energy so better to read white letters on black background
edit: me using "Quick Settings" to handle brightness etc.
Hi I am using dimmer lite download frm market place suits my usage

I would like the automatic brightness to be just a bit more brighter when im outside. Would be great to be able to adjust it!!
If there was something like a -2 -1 0 +1 +2 way to adjust it!
Dont want manually keep setting the brightness all the time.
I just tried the app called Dimmer.
It is perfect.
Goes to a very low setting and then switches back to whatever you had before.
I have the same problem with my Desire that the Auto Brightness doesn't go all the way down and the HTC Denmark support basically just said meh. And said they would report it as a wish for future updates.

This app is great! Thank you!
I have my phone on autobacklight, but I find that in dark settings its too bright!!
This app does what I want with a simple click! Shame however that there's no way to reduce the lowest brightness on auto setting built into the OS.

Touch panel type

Can someone please tell me how I can tell which type of touch panel I have
It says it in the bootloader menu at the top.
We're comin from a pure power source.
So did you find it?

Also there is some command you can type into terminal emulator to tell if you have a novatec or Epson. I don't remember what it is tho...

If your screen dims by fadding, you have novatec. If it just jumps levels, Epson

Use the brightness widget and place it on your home screen
click it - if your brightness fades slowly (where you can see the transition) you have a novatec
if it jumps meaning when you click the button its instantly brighter or darker you have an epson

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.

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 tweak light brightness down even further even lower on the S3?

My screen dim level is at 1 and my phone is still too bright. How could I reduce this even further so that sliding my brightness toggle in the notifications bar all the way to low will reduce the brightness even further? Is there not an option or a mod that allows you to pretty much dim your screen to complete darkness?

I see screen filter, the only problem I have with it is its persistent notification. As far as I can see there's no way to remove it. If I could get rid of the persistent notification I would set it to boot with tasker.
Suggestions to remove from notification?
Try lux auto brightness not sure if it has persistent notification or not.

Is there a way to lower the brightness set by the kernel or is this unchangeable?
Download screen calibrator and it works like a charm, you can also remove the icon from the status bar

I looked into this too, I believe the only option is screen filter or anything like it.. which makes no sense to me.

Yeah I actually prefer the dropdown notification built into AOKP roms for brightness, but the lowest brightness is too bright. In a room with lights off, reading the amazon kindle before bed is pretty discomforting if you're trying to ease into sleep. Way too bright.
Apparently the only way to do it unless the screen filter author comes up with a way to get rid of that persistent notification/load on startup is to kernel hack, and personally for someone who isn't a developer/programmer, I wouldn't touch an opensource code with a stick
I have the same problem. The lowest brightness is still too high to read something with the lights off.
Hey, I think I actually found something.. do you have cm10? If you do, you can turn on screen filter normally then go to settings > apps > screen filter and uncheck "show notifications". That took away the persistent notification for me.
I don't know if you can do this in aopk.
i have a great solution (with a notification-so i will try your suggestion 386 once my rom is done backing up), but want to make my own personalized "build (apps, tweaks etc) thread". Where can I make it without getting slapped by the mods? In the galaxy s3 general thread or since most of it is can be done on different android phones in the the overall general thread?

2 XL Always on display clock position issue

Hello guys!
I think found an issue on my 'Always on display'.
Normally the position of the clock is close to the central middle, but this morning i found my time has been moved to the up for a distance, so i notice this clock just doesn't look right
i don't know what I've done and i didn't find any setting option.
Did you activate screen saver?
It move the clock around

Thanks for your reply!
My screen saver is active and it has a default option 'while docked'.
Should i turn off them?
it has nothing to do with the screensaver. the movement is normal and prevents burn-in. i'm surprised nobody has said this already.

There is a separate clock with the screen saver that moves it all over the screen.
The normal clock on the ambient display is always in the same spot, just has pixels alternate on and off to lower the chance of burn in.

The screensaver clock hops to a random place every minute. The always-on display clock, as far as I remember, moves one pixel at a time, bouncing around the screen (?).
