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I originally made SuperDim for setting very low backlight settings on LCDs, and so I made it not work on non-LCD screens (e.g., OLED).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.
Has anyone else noticed that the auto brightness is really dark? Especially when compared to my s3 set to auto. Or do I have a messed up tablet?

No auto brightness sucks. You shouldn't use it anyway because it eats battery.
Yep mine sucks too.
How autobrightness works on the magnificent SGN 10.1:
1. Autobrightness ON: when You adjust the slider now You set the minimum brightness that the SGN 10.1 has to achieve. It will never get darker than the adjusted brightness level
2. Autobrightness OFF: set the wished brightness with the slider
It is genious that brightness can be adjusted within one tap ..........

Wow, thanks! This was my one gripe - that autobrightness was too dark in lowlight settings. I had resorted to manually setting brightness, but this is superb! Thanks again.
I don't understand this. Once you click the auto brightness box after doing this it's still too dark. With the box unchecked it does not auto adjust.

Well if you have the box checked you can adjust the lowest allowed brightness with the slider, just try it out in a dark room - Check the box and drag the slider.
With the box unchecked you have to manually adjust the brightness with the slider.

I understand that but with the box checked and level right up its way too dull and althpugh it adjusts automatically, every adjustment it makes is too dull.
Autobrightness drains your battery anyway. Just set your brightness manually. What is it, like 2 clicks?

Chill out bro, auto brightness is the bomb son. More so for phone than tab, but still I find auto on my note 10.1 to be total ****, it's always adjusting itself..to the point where I'm almost having an epileptic fit. I'm now forced to use manual as you suggested. 2 effing clicks, this is an outrage it's 20-12.

Auto-brightness is my only major complaint about this tablet. I have always set my Android phones to Auto and works great. This device it goes as dim as possible & never gets brighter.

Mine definitely does not work like this. I uncheck Auto and set my slider to Max brightness. The screen gets really bright. I then check the Auto box again and the screen goes back to too dim for my current conditions. The slider still shows Max (all the way to the right), though.
Anyway, I don't think working this way would be good, even if it worked. If I set the minimum brightness for where I want it when I'm bed, reading, and all the lights are off, it still won't be bright enough if I'm sitting on the couch, in the afternoon, with just light coming in the windows.
It needs a way to set an Auto Brightness offset or pad value, so you can tell it, for example, make the brightness always be 10 higher than what you would normally set it to.
Auto brightness is seriously off base on this device. Even set to totally bright and auto, it them dims it to an unusable point. Good thing I never use auto anyway.

Seems to work only on the intl 8010 models, not on 8013s. Ive had both, and thats been my experience. Definitely a major improvement on the 8010 and the way autobrightness should work (allow user to set minimum, then scale up from there).

I'm really not getting this. Someone said to check the box and then adjust the slider. Well, the slider doesn't move once I check the box.
When I check the box and then adjust the slider the check in the box goes away.
I can't even do that. The slider doesn't move with the box checked. I have to uncheck the box to move the slider, so I don't understand how this works at all.
I wish auto brightness worked. I prefer to use it on my other devices. Samsung really screwed the pooch. I hope there's a fix. I wonder if they even realize it's broke.
I'm not sure what it is with this phone's auto brightness but comparing it to my old nexus 5 I can see that this phones screen is always darker. I know autob its working because I sometimes see it change automatically but its just always set to be way too dark. I
f anyone else has this problem or know how to fix it without having to manually adjust the brightness that would help a ton.
Also if you changed your lux levels please post those.
On and also I do have the official screen protector on if that matters.

Yes, it is a little dark, you can go to settings/display & light and hit the little gear icon, hit adjust and set up the screen brightness you like depending on the ambient light.
i am facing that some time while scrolling brightness increases for some millisecond and come to normal. i found that is twitter, some huge page in browser page.
can any one tell what could be the issue hardware or just a software bug which can be fixed with other rom installation.
What am i missing regarding screen auto brightness? I keep having to manually change brightness when going from light to dark places even though i have "adapt to lighting conditions" ticked?
It feels like im wasting battery having the screen so bright at night unless i turn it down, then I have to turn it up again in the morning.. Some secret setting?

Same here, Someone said that the screen does dim but it does so slowly so you barely notice it! Hoever iam not convinced! Iam almost certain mine is not adjusting at all
For normal day light conditions i feel the auto brightness adjusts very well. Its definitely better than the s4 i had. I have the auto brightness selected and the bar at 50%. I agree for night time reading i have to manually adjust the brightness may be its not as quick to adjust in very low light conditions compared to day light
I was using CM11 on the S4 which had very good brightness control, not sure about standard. I agree during the day I don't have problems at all, and the screen is very good. It's just when I'm somewhere with low brightness and I have to turn it down, and then when I go back into day I have to turn it back up again. Pretty annoying having to change it all the time.
I will get an app to do it for me for now, but this must be some sort of bug this action couldn't be on purpose.

I find the auto brightness not very good.
Sometimes when the lighting condition does not change, it will start to increase/decrease the brightness to the level which does not suit the lighting condition.
It also have the tendency to favor lower brightness.
Thinking of trying out Lux Auto Brightness instead.

I don't know if you mean to test the sensor, but the sensor works absolutely fine (with other apps)
My auto brightness works just fine and i have mine on lowest possible setting.
When auto brightness is enabled and I'm viewing the phone in direct sunlight, the maximum brightness seems to change really quickly. It brightens and dims quickly, almost qausing a feeling of screenflicker.
With auto brightness off, the problem is non existent.
It only happens when the phone hits 100% brightness. Anyone noticed this. And is there a solution other than turning auto brightness off?
Yes I noticed this today just got mine today and sat out in sun with auto brightness on it was flashing like mad ,

For me autobrightness is useless. Simply too dark in all conditions. Also max brightness is not enough for when you have direct sun on the screen.

I have noticed the same, it's usually too dark for my taste.. would be nice if you could config how dim it goes automatically.
O saw the flickering in sunlight as well. Probably a bug
I finally gave up and installed the Lux app. Hopefully they will solve the issue in the next updates.

You're all insane. This phone has the best auto brightness I've ever used. It's very responsive without changing so fast that it becomes an issue in flickering light conditions like walking past trees where sunlight filters through or something.
I have the same problem, yes.
OLED displays have two "maximum" brightnesses; the normal maximum, which is intended for full-time use, and High Brightness/Sunlight Mode, which maxes the pixel brightnesses out for temporary outdoors full-sunlight usage.
The OP6 might have the threshold for what it considers "full sunlight" set too high, which would cause a lot of flickering in the event that the phone isn't held perfectly still in sunlight because of the light sensor output dancing back and forth across the threshold.
There's probably no changing it until someone rolls out a custom kernel in which it can be disabled or tweaked, in the meantime you can find auto-brightness apps on the Play Store that let you set custom curves (note that this'll probably require root). Hopefully OnePlus will fix it in the stock kernel themselves, terrible auto-brightness can make or break a phone in my opinion : \

I would not hold your breath. It was an issue on the 5t and not sorted during the time I had it.
Can't say I've noticed the issue on the 6 though with adaptive brightness mode enabled
Couldn't agree more autobrightness seems too dark on my op6. Under direct sunlight, I have to disable auto and full the bar myself..
Auto-Brightness is too dark for me too... Hope OnePlus will be updated this, or add the possibility to adjust the Auto-Brightness.
The minimum auto-brightness can be adjusted from the slider, it will still be auto increasing when needed but it won't go below your threshold.
I'm testing this for a few days and it's working perfect, the minimum was also to low for me initially.
I've tested the auto-brightness with a flashlight:

EVERYONE WITH BRIGHTNESS ISSUE,
There are No problems with screen, it's flawless.. Although people dealing with auto brightness issue,should disable the night mode.. Cause when night mode is active, auto brightness tends to use more dark screen as dark as possible..

Actually I like yellow tinted screen(warm colors) , for that I enabled night mode. Since then I was facing problems like too dark in direct sun on auto brightness. Too dark even in room. Today I accidentally turned off night mode while showing handset to my friends.. And voila brightness got up nd up nd up... I tried in direct sunlight, now I don't have any problem viewing my handset even after wearing shades..
If there is still problem in ur auto brightness then bro I strongly suggest u to compare ur handset with other op6 cause it could be a manufacturing defects... I heard a developer got flickering issues, he returned handset..

I have auto tightness issue also. Have not noticed flashing, but screen dims often. Even when using phone, and in a steady lighted area such as indoors.
