Is there anyway to make the auto brightness transitions smoother? They seem to go in steps to lower or brighter settings rather than a smooth fade.
Also, when unlocking the screen, the screen turns on in a 2 step fashion...It powers on, then brightensa bit...is there anyway to make it smooth? I am coming from a HD2 and that had VERY smooth transitions and power on with regards to brightness change.
Edit. I am using Stock Jl4 2.2 rom with supercurios voodoo kernel.
anyone???????

Is it just me or does everyone's Epic's have terrible brightness sensor hardware/software? My sensor seems to have about 2-3 settings of brightness, and goes from completely dim to super bright in random situations and nothing in between.
Cyanogen just posted on his twitter that in the past he changed the sensor's abilities through coding modifications. Could we do something of the sort for the Epic's sensor?
Agreed. The sensor is horrible. Also, the transition between brightness settings when set to automatic is near instant instead of slowly transitioning, which makes it more obvious that its changing brightness.
I would agree that it is terrible. Mine also send to sometimes turn auto brightness back on if I've turned it off.
It would be great if someone found a way to mod the code for it!

I thought the screen was just too bright at its lowest setting. Fortunately someone came up with a fix for it that can be found in the developer section. As far as the automatic sensor I would suggest turning off "Power Saving Mode" in the Settings>Sound & Display as well. I've read somewhere that this causes the brightness level to vary on its own.

Hehe, that was me. Stay tuned for more. I have coded up and will post, tonight, a new version that will let you modify the brightness curve (from the command line, for now)
As for automatic mode, I have figured out how to modify some aspects of it at the kernel level, such as the ambient light thresholds at which it switches to a different brightness level. By modifying the brightness curve, we can achieve at least some more control. But to make it really good may be significantly harder.
Personally, since manual brightness is always available by swiping horizontally on the status bar, I have little desire to use auto mode anyway.

The sensor is actually pretty sensitive. It's just that Samsung chose to have a really small range of brightness steps for automatic brightness.

More like they installed an awesome dimmer switch and lights, but the fixture only does three modes; high, medium, and still pretty damn bright.
Here's my dilemma... I like saving battery by setting my brightness level lower than the automatic setting (since the screen still looks great anyway), but I would like it if I didn't have to go into my settings manually to change the brightness level so that I can see the screen when in direct sunlight. Is there any way someone could develop a mod to have the automatic brightness, but about 20% dimmer? I don't know if it's possible, but it would be pretty awesome.

I have my screen set pretty dim, and use the Power widget to crank up the brightness if I go outside.
You can also you the "Screen Filter' app to make the screen x% darker than the current setting. (which even allows you to make it darker than the dimmest brightness settting, which is really nice on the batteries.)

I am current searching for the same thing.
temp solution is to Market > Dimmer (night mode) by geekyouup
It toggles auto brightness and sets back light to min. when on. click once, screen goes super dark, click it again, auto brightness take over. handy. (put it up to status bar w/ bar control and you can get to it when ever)
Problem with auto brightness right now is at it's lowest setting, the back light is still at about 25%. there is gotta be a way to change that in the settings.apk
or better yet, have an option to set your own ambient light to lcd brightness ratio for the auto brightness
option to set own ambient light ratio?

I'm search for this also. I believe you can adjust this in CM7 but is there is a way to do this that is not ROM specific? I'm currently using RoyalGlacier with Faux123 kernel and I find the auto brightness setting for dim ambient to be too bright and the bright ambient to be not bright enough.
I noticed that the brightness only brightens but never dims back in automatic brightness display setting. I can reproduce this easy with turning the lamp on my desk on and off. It only goes back to the lower brightness if turning the screen off and on again.
Noticed this too but seems to only occur when I use a widget to toggle between Auto and 100%.
If I leave the setting in Auto from within settings then it seems to work. Brightness widgets seem to break the auto functionality.
Hmm, I don't use a brightness widget. The light of the softbuttons go on if I cover the light sensor, but the screens stays in high brightness.

Must be an all around bug then. If you turn the Atrix off and back on then the auto brightness functionality is restored.

This must be an Android thing. My Atrix does the same thing, as did the Nexus One I had before. I've had several (high end) Nokia's that dimmed/brightened perfectly. After 5 seconds, they would brighten (or dim) accordingly. I was hoping Motorola was better at making phones than HTC (the KING of bad battery life). We ALL lose here. Our precious battery life is being drained by the poor execution of a simple function.
This is a stock android thing (problem). Custom ROMs can allow it to dim and change brightness smoothly rather than in discrete steps (Cyanogen).
That's what I thought. I found this free app called "esdimmer". It supposed to be for Galaxy phones, but it's somewhat working on my Atrix. Does this function work any better in Gingerbread?

Well it's good to hear that it's a stock android problem and not the actual phone. I did find a way to get around this problem but it's very limited. You can get the screen to dim by first putting the phone into standby and then press the standby button once again (which gets you into the lock screen). You'll notice that the screen then dims (if coming from a well lit area/room to a darker one).
Since I flashed the leedroid rom, automatic brightness doesn't work too well. The display is always very dark...even if I go in the sun, the brightness doesn't go maximum. If I manually set it to maximum, then I can tell the difference with the automatic brightness level which is much darker (around 40% brightness level).
No matter what rom I use (I flashed today ultimate droid, revolution HD, miui)....with everyrom the same thing. The sensor is not dirty, I thought maybe it doesn't get too much light so the phone doesn't recognize how bright is the environment but yeah...it doesn't really look right to me.
Before every rom I always to a full wipe through clockwork recovery....what can I check ?
Use app "sensor list" or the the lux (brightness) on "gps status" to check if your sensor is actually working. The values should change between:
10-40-90-160-225-320-640-1280-2600-10240
They may skip some values going through the range, and maybe take a few seconds for the values to change or register on your display.
Use a torch to gradually shine over the sensor, so you can see the autobrightness change along with the lux reading.

Hi, started this thread to see if anyone had the same problem I'm having with my screen.
I have a Galaxy S4 GT-I9500 (Octa-core variation), it is running 4.4.2, rooted, stock Touchwiz.
The problem is that the screen starts to flicker almost as if it would want to turn off, when in low light conditions and auto-brightness on, it continues to flicker unless I set the brightness between +2 and +5. I can reproduce the issue without auto-brightness setting the brightness to the lowest, one notch above the lowest and there is no flickering. It is noticeable in white backgrounds and also when swiping down the notification center, that's the most noticeable instance but you can see it in the home screen and in any app.
I started noticing it when I had 4.2.2 Jelly bean (rooted), and I updated to Kitkat hoping it would be solved but it is the same, I updated through Kies and rooted, no Factory reset, I want to try that as last resort.
Funny thing I discovered is when I set Juice Defender to control my brightness it does not flicker even in -60% brightness, but when the dimming happens before the screen turns off it does flicker (and the dimming thing is controlled by the OS I think, not Juice Defender).
I wish I could put up a video but I don't have another phone to film it.
Anyone know if this is software or hardware? What can I do?
I'd like to add, that I changed the battery, disabled overlays in developers option, forced GPU rendering, tried Pimp my rom and played with all the settings, checked and unchecked every option in Display settings and it still flickered given the low brightness conditions.
I think I've found the best solution out there for most annoying screen flickering issues... Done a substential amount of digging and finally discovered the app "Twillight" works like a charm by enabling backlight control feature... Try it out first, then thank me and share your experience here ...
