[SOLVED] brightness hack? - Kindle Fire General

How can I decrease the minimum brightness? The fire simply does not get dim enough for me to read books in bed.
Fully rooted.

I sometimes reverse the colors so that it is white on black while reading at night.

Try useing Display Brightness v.2.2 (from RubberBigPepper).
It gives you far better control of brightness in 1% incraments and it can adjust the brightness to a lesser level then the KF controls allow. By it's measurmement the KF controls only scale from 11-100%, so you can definatly get the screen dimmer and save power. Best of all this program will work on Non-Rooted machines and thereby becomes a must for all KF users.
Look for it in the market place or other locations as a sideloaded APK.
Enjoy!

On a rooted device, you can also use AdjBrightness (in the Market) or my RootDim (in the Market, Appstore and here). Both are free and will let you go one step below what looks to me like the 1% minimum setting of Display Brightness, to 0.4%.
On a non-rooted device, you can also use my paid ScreenDim (in the Market and Amazon appstore), which adjusts brightness down 0.4% and also has a separate contrast control.
But if you want the on-every-screen adjust bar, Display Brightness is the way to go.

Awesome guys! Thanks.
Edit: I could not get RootDim to keep the brightness after exiting the app even with SuperUser privileges.. Display Brightness works like a charm!

Ran across the same issue. This solved it for me:
Screen Filter
(search android market, as forum won't let me post the link)
Works great!, and it lets you add a custom widget to the desktop to dim and undim with a single click.

You might try DisplayBrightness. It puts a custom slider that is available on EVERY screen to adjust brightness down to 1%.

I don't have a rooted Kindle, so I can't test it. Is Safe Mode off? Have you tried setting the lock in RootDim?
RootDim, AdjBrightness and ScreenDim (and I have tested ScreenDim heavily on the Kindle Fire) will get you to a slightly dimmer level (0.4%) than the 1% Display Brightness does, though that probably doesn't matter to you.

Yeah, I tired the 'lock' setting, but did not work.
Actually I was thinking that below 1% might be necessary for my needs. I'll check those apps out.

I recommend flashing cm7 and using rendering in settings menu for a nice Retro red or green monitor effect!

You can also get that with ChainFire3D on a rooted device.

adjusting auto-brightness range

Looked on google for this and found other people asking about it but no answer so far.
If i leave the screen brightness set to auto-adjust, the phone NEVER adjust the screen brightness down to it's lowest setting, even if i am sitting in a pitch dark room. Is there some way to adjust the range of the brightness setting so that it will actually use the lowest brightness? It seems beyond stupid that in a pitch dark room the screen doesn't go down to it's lowest level.
Most of the time i find the screen to be too bright, so if i could adjust the auto-brightness over-all to be darker, that would be cool too.
failing that, is there an app that makes adjusting the brightness quicker then digging down into the settings to move the slider?
thanks
I use widgetsoid (free) from the market place to do what you speak of and 7 other things as well.
i think i already have something that does what it looks like widgetsoid does. I have a button on the screen that i can tap that switches the screen between 3 brightness settings. i was just wondering if there was one where you could tap and get a slider. Seems silly to have the actual slider itself on the screen since that would take up so much room. But a button that would open up into a slider would be nice.
I'd still prefer to be able to adjust the autobrightness settings and use that if possible.
You can set autobrightness levels with tasker. There's a thread floating around with details.

Again, Widgetsoid does this. Once it is setup, modify, settings/Brightness Modes and set it Custom (Seekbar) or use one of the other 2 settings. You can change those as well with custom. Exit. Go to toggle and you have slider with one click on one button, which option of adding 7 more.

ah ok, cool, thanks. I'm going to see if i can find the thread about tasker since i'd prefer to have auto-brightness working better. if that fails then i'll give widgetsoid a try.
thank you
Just what I was looking for Screen brightness less then 10% and Less then Curvefish's toggle to 4%. I was looking for the 1% brighness and I think i got with the Widgetsoid only compaint is no exit after setting... Thanks

How to decrease minimum backlight level?

Is there a way to decrease the minimum back-light level on a CM7 ROM?
I always prefer to keep back-light level as low as possible and not using automatic setting for it.
Recently I've tried one of the MIUI roms and noticed that the lowest back-light level on it is way dimmer that on CM7 ROMs. It allowed me to noticeably save on battery.
So is there any way to do it on CM7 based ROMs?
http://forum.xda-developers.com/showpost.php?p=14089317&postcount=10594
Tried and tested with typhoon rom. After usind this lib the cm7 autobacklight level should woork correctly..but therefore some LED Notification will behave a bit strange...you will be able to life with that. (=

not 100% as I use a CM mod (AMA), but check Settings / CM Settings / Display/ Automatic Brightness / Edit Other Levels

OK. I've tried it and saw absolutely no difference in minimum backlight level.
When I move the backlight level slider all the way down it is still on the same level
as with older libs. And it did break notification lights.
As I've mentioned before I am not using autobacklight at all. I just want to have manual backlight level go much lower.
There is a free app in the Android Market that will do just what you want. It's called Screen Filter. Using this app, you can set your backlight level very low, and even put a widget pre-set to your preferred brightness level on one of your homescreens.

that's how it looks on my device - the min brightness can be set to 1 which is very dark

This app is a fake. It does not decrease backlight level, but instead dims lcd pixels, which is not the same. Hence no power saving benefits. It would only help with OLED screens.

Did you replace lights libs to make it to work?

that's how it comes with AMA, which is based on CM7.1, so it could be part of the original CM (have no way to check as I don't use NAND builds)

Ah..I see. That is SD build.
OK. Looks like CM7 autobacklight works if I replace lights libs now (loosing LED blinking though). I guess I'll try it out and see how it turns out.
Thank you all.
One thing I've noticed that backlight level number is not very granular.
As there is no difference if I have it set to 1, 5, 10, 15 or 20. It only changes at 25

it might depend on the brightness ranges/thresholds - I've noticed in my build that if first two ranges are set as 0-100 and 100-200, the first one is ignored if upper limit is below 225, so I always get the screen brightness of the second range
I was looking for a dimmer lowest setting for the back light & tried Screen Filter BUT found it left the "black screen" well lit but everything else faded, almost like the colours were merging to gray rather than being dimmer.
Anyway, my need was for the clock display to be dim but found the Clock app's day/night mode button takes the clock display brightness right down low; lower than the manual screen brightness setting for sure... but only in the clock.
Hopefully any other noobs to Cyanogen / non-Sense ROMs may find this relevant! ;.)

[Q] backlight hack

i find myself using the tablet on lowest light settings all the time, without any trouble.
does anyone know of an app that would let me lower the backlight settings further than what honeycomb allows ?
battery use at 70% --;

I use an app called screen filter. It doesn't actually lower the blacklight but it does the trick.
Theres a couple other apps that do the same thing.
Fantastic! Tkvm ^^
This should appeease my quest for the st graal that is screen color inversion

[Tutorial] How to reactivate autobrightness

I just played with the brightness of my Arc and noticed that the autobrightness was deactivated afterwards.
I downloaded a lot of widgets to set it back to auto, but it didn't work with a lot of them.
Then I finally found "widgetsoid" and that finally worked to set it back to auto.
So if anyone else has the same problem, here you have the right widget and don't have to spend time on finding the right app or widget.
Hope that helps you guys, because I found it beeing very annoying.
Regards,
Flo
In SE's Xperia line of phones, auto-brightness is ALWAYS enabled, no matter what you do (unless you run a non-stock custom ROM).
Try this, put the brightness slider around the 40% mark, shine a light on the sensor, if there's enough light, it will go to full brightness in no time. The same goes conversely.
And how to disable without use third part apps?
have anybody tried this app ? is it good ?
i read bad reviews like :
- unable to uninstall
- lag
- flood the widget list with so many stuff
etc etc
but it just reviews, so it might not be true, i don't know...
@ doomed and Lucas:
I just put the slider to max and then back down and it didn't work untill I set it to auto again with the app I mentioned in first post.

Widgetsoid is a fantastic program and works 100% with the Arc / Arc S
The auto brightness feature does work to a point, but you can also toggle 3 different percentages to suit where you are. I have mine set at 30%, 70% and 100%. You can also have a slider if you wish.
No problems at all with the app, although it's a bit complex to set up first time you won't be able to live without it in the end. Loads of options and configurations to keep anyone happy!

Auto brightness is disabled at the minimum and maximum point, only in the middle.
Ah, didn't know that.
In the middle it just worked a bit if even
After setting it back with the app I got it working again and I hope to have the stock SE setting back now.
I'm happy.
For people who get the same strange bug this might be usefull.

+1 for widgetsoid - I'm a long time user with my current Arc and previous HTC Desires and Hero phones.
As has already been said, its a bit complicated to set up initially but allows great functionality in a single widget.
Well worth a try.
i've been playing with it for a day now.
haven't check the auto-brightness feature yet, i downloaded this app at 6pm, so its already dark here. i've taken the arc on the street at night, and under room lighting, so far i think its always stay at 30% brightness. i'll see if this feature works under direct sunlight
there's a widget to view cpu temp and storage (rom,sd,ram) status now
just wondering, is there a way to make the storage status more accurate.
most the time, the ram status doesn't show the latest status. maybe there's a setting to make it check the ram status more uptodate

i have no idea about this. please explain it for me
The only thing I hate about widgetsoid is that you can't backup your setup, so if you do a Nandroid restore, you'll have to set up each widget again. I had about 8 switches, and then you have to choose a function, colour, opacity. Really sucks.

[Q] Schedule an app to run and close per time?

I'm looking for a decent app scheduler that can run an app by a set timed schedule?
I'm looking to start this screen dimming app (super dimmer), by a set schedule, around 8pm and to turn off at 6am.
The app itself does have an internal scheduler, but it does not work correctly, but the app works exactly as I need.
So what do I need to do this?
What exactly am i trying to do?
Well, I like the auto dimming feature of my phone, however at night, I do not like the lowest default dimming setting, I am comfortable with a much lower dim setting that Super Dimmer can provide. I basically want it to activate at sun down and deactivate at sun rise.
I would be even more interested in adjusting the phones default dimming ratio, if that is possible, if I can control and lower the auto dim setting in phone, that is preferable.
Taskbomb task scheduler?
Sent from my MyTouch 4G using XDA App
I did install taskbomb before writing this post, is that what I want to use? I just have no idea how to configure it.
Tasker is awesome. You shouldn't even need to use a secondary app with it.
Sent from my MyTouch 4G using xda premium
Well looks like my idea did not work correctly. For some reason that program doesn't toggle on and off like I would need it to in order to work with taskbomber.
So this tasker app, does it allow for dimmer settings below the default android 0%? I'm looking for 200 levels.

I havent tried to myself, but it does have ability to ask for SU and device admin permissions so I bet it does.
I got it, tried it, it does allow for you to set lower than default values for some devices but for some reason it doesnt go as low as super dimmer did.......
Hmm I'm all out of ideas now!
