Hi, I have an I9100G, with rooted stock ROM, firmware DZKI1, Android 2.3.5. I'm just curious about a couple of items in the Display settings. There's an option called Brightness - Adjust the brightness of the screen, and when we click it, we can adjust the brightness or select the checkbox for Automatic brightness. On the same screen, a bit further down, there's another setting for Auto adjust screen power - Save power by analyzing image and adjusting LCD brightness. Anybody knows what's the difference between the two?
One uses an external light sensor to adjust for lighting conditions.
the other uses an internal sensor to adjust the colour display depending on the background of the graphic and how many colours are used.
Hey
Is there anyone who can make a widget or app with widget support for toggling ultrabrightness in CM roms with just a one click?
It is not nice on very sunny days to search options in our phones even with 100% brightness, can't see screen sometimes
Thanks in advance.
Cheers.
you can do the following settings:
enable ultra brightness
go to automatic backlight, enable use costum
screen dim level to 4
edit other levels:
0-3 screen 4
4-15 screen x (you choose)
16 - 63 screen x
64 -249 screen x
250-infinite screen 255
when your sensor detects 250, you will have ultrabrightness+255 screen level.
when your sensor detects lesser light, it willh ave ultrabrightness, but the low dim compensates.
post here if you have anymore questions regarding this issue
I know that i can get this work with this way (autobrightness enabled) but maybe someone can do this what i'm asking..
If not, i'll must use this solution.
hi all, I noticed that light sensor doesnt work properly, when I go from dark to light area, the brightness increases but when I go from light to dark area the brightness wont decrease, on honeycomb it worked properly, anybody else experiences this problem?
Same here, it goes bright but does not decrease.
I use the app https://play.google.com/store/apps/details?id=rubberbigpepper.DisplayBrightness&feature=search_result#?t=W251bGwsMSwxLDEsInJ1YmJlcmJpZ3BlcHBlci5EaXNwbGF5QnJpZ2h0bmVzcyJd
make an invisible slider on the edge of screen to adjust brightness.
is there any way to make it work properly?
Don't think so. Its pretty much unusable now.

There are lots of negative comments about light sensor, but i have to say it works well to me on ICS. Could be possibly massive amount of defected devices.
Lightsensor doesn't work for me either - too bad, hope it will be corrected.
Perhaps it's because I'm running ICS "General Channel".

Do the sensor dim the light in the same session for you?
Here it turns up the light but not down again.

Same here, adjusting upwards works fine, but it doesn't adjust downwards in low light conditions.
I have tried two apps that turns the light down again, custom auto brightness and lux auto brightness.
One small problem. The pad will crash on pattern unlock after sleep. I Also the light sensor will not work s after wake up sometimes.

Click to collapse
I'm guessing no one has had any luck with this issue but I figure I'd necro the thread anyways. My light sensor sucks also. I used 'Android Sensor Box' to get the values coming out of the sensor. It only displays either 40 lux or 280 lux which is obviously not right. This is on Cyanogen 9, stock t-mobile ICS and the rooted international gingerbread(can't remember which one exactly).
So I was wondering if anyone who owns one of these has ever gotten a sensor value that makes any sense.
thanks
nope,
I use instead display brightness https://play.google.com/store/apps/details?id=rubberbigpepper.DisplayBrightness&hl=no
create an invisible brightness slider on theedge of the screen.
Try using custom auto brightness with the auto brightness on (there's a setting in that app that disabled the system auto brightness at screen on. Turn it off).
The original kernel only recognized 3 light levels. If you use bart's kernel it will recognize 6 levels.
Yes, I think there's a software problem because both app (lux and cua) crash hard in HMP, but I don't think fixing it is a priority.

How to use custom auto brightness without crashing the tablet.
There are 2 options that should be followed, other settings can be adjusted to your liking.
1. In preferences, Check Use pulsed sensor mode. Basically this option will make the app read the sensor itself instead of listening the sensor value given from the system.
2. In advanced preferences, set the sensor update speed to either half sec or 1 sec. I tried normal, but the app won't read the sensor value, so probably the slow normal maximum setting only works if you get the sensor value from the system.
You can set disable system auto brightness. I recommend it before because the setting was a "hack" which was making the system read the brightness value thus the app can get that value. Right now it's recommended that you check the disable system auto brightness.
Hey guys
In my old phone the galaxy ace there was something known as render effect which would change the visual color of the screen.
Is possible to get it in the S3?
I basically need the night mode. I use my phone a lot in the night with zero secondary light hence the screen is too bright even on minimum brightness.
I tried screen filter app... But beyond certain limit you can't read anything on the screen
The night mode + screen filter was my settings during the night to reduce brightness on my old phone.
How can I get it on the S3?
"Render Effect Galaxy Ace" brings up no worthwhile results, so I have no idea what specific effect you're on about, but the app Galactic Night has some effects. If you're running the Siyah Kernel or Perseus, they also support custom mDNIE profiles, so if you have a lot of time...
I just want something that will lower my screen brightness
Similar to screen filter app
With Lux you can lower the screen brightness below the stock minimum (automatically our manually) .

Works great.
During night time it is very useful it can decrease your brightness to EXTREME LOW.
I had a great Macrodroid macro that would check for the ambient's light levels and then set the display brightness according to my preferences everytime I would unlock the phone.
It worked way better than setting "adaptive brightness" to on.
On the Mi A3, it won't work correctly though: when I set brightness level to 20% at a certain light level (for example between 200 and 400 lm) the actual brightness will be set much higher than 20%.
Anyone has any suggestions?
Thanks
