RootDim (formerly known as ScreenDim) lets you set the screen brightness on backlit screens below what the OS normally allows, which is handy for amateur astronomy where the lowest normal OS backlight setting (even with a red nightmode) leaks enough through the black pixels to damage night vision. Moreover, SuperDim lets have several brightness profiles, and to include nightmode settings (enabled by ChainFire3D or Cyanogenmod's render fx) as part of the brightness profile.
Needs root.
Public domain, source code available. In Market (search for RootDim).
Now in Market (free, no ads).
I just uploaded version 1.10, which restores low brightness settings after the screen is turned off and back on (the OS normally was restoring its brighter screen).
Works well, but seems to mess with the functionality of the notification/charge LED (Nexus One, CM7.1)

I assume this is when you use the other lights option to toggle these lights, or when you restore a profile, right?
In version 1.11 (just uploaded), I no longer restore other lights when a profile is loaded--this should help with your problem, as long as you don't touch the other lights. Eventually, I may add an option to choose which lights get restored from a profile.
I originally made SuperDim for setting very low backlight settings on LCDs, and so I made it not work on non-LCD screens (e.g., OLED). But I've since realized that the profile feature might be useful for non-LCD users as well, so I've released version 1.20 that supports non-LCD screens. It's in Market. While I was at it, I cleaned up the code a little, made it more javaish (I'm new to java).
My MyTouch 4G just seems to turn the screen off totally if i go below 20 brightness, it dims but then shuts off.
Doesn't work at all with Dell Streak 5
I'm sorry to say, but Screen Filter does the same, but doesn't require root.

Actually, all Screen Filter does is dim the colour of the pixels. This app actually modifies the screen backlight level. E.g. Screen Filter just makes the screen gray-er.
Also, works good on Sony Ericsson Xperia X10, but the backlight completly switches of when set to under 15.

Screen filter merely adds a black semi-transparent overlay across the screen, making it look dimmer.
This app adjusts the backlight, which means darker black levels on the screen.

Your eyes would probably care if you were doing amateur astronomy under a dark sky (which is the primary purpose for SuperDim). Screen Filter doesn't turn down the backlight, and on a lot of devices there is enough backlight leaking through even completely black pixels to damage night vision. You can try this experiment. Turn a backlit device to a completely black screen (maybe view a black jpg) and take it to a completely dark room. Let your eyes dark adapt. The "black" screen will in fact probably be quite grey. (If it's really black, that's probably because you have an OLED device.)
When I do amateur astronomy, I am not infrequently looking to see objects way dimmer than backlit black pixels.
I'd like to do something about the screen turning completely off issue.
To that end, I need people to do some experiments for me, and I will be very grateful (I'll also give a free full version of Force2SD as compensation for the first couple of experimenters, if you want it--just email me). The first experiment is this. Download SuperDim 1.22, now up in the Market. Press the menu key, and choose "Turn on safe mode" (you can tell safe mode is on, because next time you pull up the menu, it says "Turn off safe mode"). Now, turn brightness down to 10. Does your screen turn off?
I should warn that very low brightness levels can be very low indeed. For instance, if I am outdoors on a sunny day, I have trouble telling the difference between brightness 4 and off. So you need to be in a dark area--I recommend a room without windows and with the lights off.
If the screen does not turn off at 10, turn it down to 5, and then 1. Let me know if it ever turns off.
I am guessing that in safe mode, it doesn't turn off at all.
What safe mode does is it makes very low brightness settings not persist. So if you are in safe mode and leave SuperDim, you lose your low brightness setting.
I'd also appreciate it if people who can normally turn their brightness down to 1 could do some experiments with safe mode. Specifically, I'd like to know if moving the slider to 1 in safe mode has the same effect on screen brightness as moving the slider to 1 in non-safe mode has. (Again, if you're one of the first few experimenters and want a free copy of Force2SD, email me.)
On my Archos 43, brightness 1 is very, very dim, but the screen is still on. And I can't tell the difference between safe mode and non-safe mode, except that in safe mode, the settings don't persist after I leave SuperDim.
Tried this app on my desire HD.
Great idea, but when I reach 10 and below, the backlight doesn't get lower.
If I use the adb method (don't remember the command), I can set the backlight manually all the way down to 0.
There is no difference with or without safe mode on.

What happens? And does safe mode work?
I agree, doesn't work with Desire HD/Inspire 4G, safe mode only dims the brightness but no lower than normal, and only dims the brightness on the screen, regardless of your settings

I found a bug. In fact, the bug is such that I have no idea how it was managing to work on my device at all! In any case, I think I fixed it. Try 1.23 (should be in Market or here) and see if it does the job. If not, I have some more ideas.
Hi guys, using my Nexus 5 I noticed the brightness was very inconsistent, even with auto brightness turned off the screen seems to dim occasionally and then go back to full brightness during use.
Have you noticed it too, and is there any way to stop it from happening? I would really like to be able to enjoy the beautiful screen at full brightness without it going dim randomly, thanks.

Yes I noticed it too, but don't know if it is a software bug or a feature to prevent from overheating (like Samsung devices do) or a hardware problem. It is quite annoying!
So, even with auto brightness off the screen will dim, seems to be a power saving feature but it's so poorly implented.
Just writting this message the brightness went from 100% to dim to 100% again, is there any solution to keep the brightness at 100% all the time?
Do you mean after a certain amount of time? It could be the dim before it auto-turns off the screen. You could extend the time it takes before it dims and turns off screen by increasing the timeout in display settings.

No, what I'm talking about is that the screen will periodically get dimmer during use, as a power saving measure or because of overheating, I don't know.
You need to be at full brightness to begin with to notice the drop in brightness, it's not ultra obvious but it's definitely there. The device seems incapable of staying at full brightness for a prolonged time.
I got my Moto G3 yesterday and I noticed the screen was very bright, I checked the brightness level and it was on the middle of the slider, with Adaptive Display on. I tried adjusting the slider but nthing happens, I tried turning Adaptive Display off, still nothing happens. Doesn't matter if I'm in a room with no light or if I'm outside on the sun, the screen is always on what I assume is 100% brightness.
I have also tried a factory reset, updated to Android 6, downloaded a 3rd party app to adjust brightness, getting it on safe mode... nothing works
It is really annoying having the display at full brightness always, battery drains, phone screen gets really hot, etc
Someone have a possible solution? I don't want to stay more days without a phone by taking it to warranty.
Even I noticed that the screen's brightness is same from 1% to 30% (approx).. It doesn't change at all.
What variant do you guys have?
