I have exactly the same issue and would be interested in any information to explain this.
Do you have power saving enabled? If so it will automatically reduce the brightness if battery goes low.
Glad I'm not only one
Nope not got power save on or any app which could change settings very strange would like to get to the bottom of it
The only thing i can think is maybe you dragged your finger across the status bar and manually changed the brightness setting.
I have noticed if the battery charge is below 15% the adjust brightness is greyed out in the settings and the brightness is set to the lowest level whether you have the power saving set or not, and if you force the brightness up using the power bar widget , when you phone goes to sleep and wakes up your brightness is back to the lowest setting, but as soon as you charge your phone , the brightness returns to normal.
+1 on TinderBox's comment if the battery is low (not sure how low but my test was under 7%) regardless of settings the brightness keeps getting turned down. When watching video or locking the screen etc.

can someone please tell me how to disable auto brightness on
x10i eternity rom build 003
i tried using every brightness app/widget possible to turn it off but as soon as i turn it off and put the phone under different light setting i can see that the auto brightness is still on
i tried using adjbrightness but it keeps telling me that my phone isnt rooted; anyone get this app to work on x10??
please help n sorry if this questions been asked and answered before. this forum is getting too big and broad sometimes to find anything
thx in advance
Have you tried Sparepart? (That's the name)
Strange, i can't seem to turn on my autobrightness. It used to work perfectly in android 1.6. And i haven't noticed it untill recently. When auto brightness is checked, it just stays the same, even when i hold it directly under a lamp. Maby there is a bug in the software that prevents switching it on or off?
I'd also like an answer to this problem, because with auto brightness on the telephone is a battery eater.. you have to keep it to the minimum level to disable it, but when you are under a strong light, like outdoor with a sunny weather, it's difficult to see your screen's details. as you select a brightness level different from zero, the autobrightness turns on and eats the battery.
I hope I'm missing the solution to this, and somebody will help, because all the applications i've tried (spareparts included) didn't worked.
I'm quite confuse now.....
What actually do we need......
Turn it on...
or
Turn it off...
LOL
heh, so some people want a way to turn it off and others, like me, want to find a way to turn it on?
what a crazy phone..
I'm sure there used to be a tick box in the display settings to turn on/off the auto brightness. Anyway, i've tried various applications myself to get it on but nothing does it. I think the best solution is for us all to swap phones .
Spare Parts doesn't work for me, i tried enabling it, restarting the phone and jumping under my duvet.. but it didn't change
Did you update to 2.1? It was disabled in 2.1 as far as I know.
So the easiest solution, upgrade to 2.1! Else, I don't remember the menu but it's somewhere in the settings under 1.6.
I think we've all updated to 2.1 here =)
and yes, in 1.6 there was a box to tick to unable/disable autobrightness.
But, in 2.1, this feature has disappeared, leaving a seekbar and a damned widget which doesn't allow you to set or no autobrightness.
Hi,
The autobrightness is still there. It can be turned on/of from a stock SE connection widget. The different state for brightness is "minimum" -> "auto" -> "maximum"

I can get, either 0%, or 100% brightness, with the ambient sensor disabled. Anything in-between, fades constantly.
No fix for this, i presume?
Reading websites while the screen fades in/out every couple of seconds drives me mad.
Ive never had any problem with it as long as you dont lean in front of it all the time lol.

So I know this should go in the nightly thread but I have less than 10 posts so I can't post there yet.
I got the brightness slider in CM N94 working, but it has a strange interaction with Handcent. When I open Handcent the brightness goes down to the minimum. I adjust the brightness, send a message, turn the screen off, then when I turn it on again the brightness is back down at the minimum. Same with exiting the app and relaunching.
Anyone else experience the same thing?
Check your settings in hancent for something called display mode and switch it from night mode/smart mode to normal mode and it will stop auto dimming.

Awesome, worked, thanks.
was having that issue also thanks to both
no prob. guys. i only knew about it cuz i experimented with everything in handcent.
OK I'm not talking about auto brightness, does the 'Auto ajust screen power' save battery? What about if my screen brightness is on minimum? Cheers guys!

It depends
Having the brightness set to low will save battery. The auto works best for me but don't forget you can press then swipe along the top of the phone where the notification bar is to manually change the brightness at any time.
The first week I had my phone I had the brightness of low and after that I decided to just enjoy the great screen and leave it on auto.
Regards,
John.

I tried it and didn't notice any difference, in fact it's not doing anything at all, so I have no idea what it's suppose to do to save power.
I was messing around with the settings on my phone to try and eek out some more battery life. I noticed with the stock battery monitor that the screen was using the most battery (as is expected) so I turned the brightness setting all the way down using the slidebar in settings.
Then I went into the Sprint Zone app, clicked help, then my device, then power controls. There it shows what is turned on on the phone and a general breakdown of how much those things are drawing on the battery (kinda nifty). On the lowest possible brightness setting it says it's at 11% and that that's "medium" usage. Is there a way to get screen Brightness lower? I just find it odd that it still registers as medium usage on its lowest setting...
Also has anyone noticed that on the "Automatic" screen brightness setting that the screen doesn't go as dark as it could go when there is a low light condition? For example if I'm sitting in the dark with auto brightness on, I can turn it off then make the screen darker manually than it would go on auto.
Any thoughts? Or fixes?

Try rootdim. Also, the screen brightness is going to be mostly controlled by the kernel, so try using a different kernel or build one from source.

It's not in the kernel, it's in an xml or something. There are seven brightness levels (I think it's seven) based on lumens, and there's an associated screen brightness value assigned to each on a scale of 0 to 255. Stock auto brightness levels set the bottom three levels to the same brigness value. I think it's 63. Setting the brightness manually, you can go as low as single digits, maybe even zero.

That's cool you can edit the XML files, but how can screen luminosity or display not be part of the kernel or kernel modules? I have an HD2 with CM7 on it, and through installing different kernels and whatnot, I can get different features for display like render effect, auto brightness, and whatnot. Is this only just for sense ROMs then?

So maybe the stock rom doesn't let you zero it out? It's posting the lowest value as 11% as read by the Sprint Zone app. Maybe they do it as a safeguard against setting it too low and not being able to see the screen to turn it up when it gets in a brighter environment?
That's a funny thought, I could see me kicking myself over something like that. Would be nice if we could make that call on our own though, wonder how dim it is...and why not make the auto brightness go to the lowest setting (or perhaps even lower than the stock setting)? At least then it would ramp back up as needed.

Did you try rootdim? I'm pretty sure you can dim the screen lower than stock with it on this phone. I've only used it on my HD2, but it worked well with it and It's free.
Nm rootdim only allows the screen to go down to a value of 30. You can set lower values, but it doesn't change the brightness.

Correct - stock only lets the brightness go down to 11%. I'm not sure if auto brightness will ever set it that low though, doesn't seem like it does.

Yea that's what I'm saying it doesn't go to the minimum. I mean I'm sure the battery savings isn't much, but another usefulness of it going that dark is when you check your phone at night in the car you don't want the phone to be all lit up inviting attention.

I think 11% is probably dim enough for most cases. If you have a dark background that will help with the car situation. The only time I find it still too bright is when I'm laying in bed at night. I haven't rooted yet so I can't comment on the solutions others suggested but give that a try. You probably won't save that much battery though unless you're in the dark a lot.
Oh - and don't text and drive
I use an app called screen filter at night. It allows the screen to get MUCH dimmer.

Hello Guys!!
Have anybody missed AUTO BRIGHTNESS feature in L9 because lack of Ambient Light Sensor,
If yes, the don't worry. I have an easy solution for Auto Brightness, Yes you can use Auto Brightness on LG Optimus L9:victory:
NO ROOT REQUIRED
Download and install These two app from following links:-
Lux Auto Brightness
Tasker
After Installing these apps follow these steps:-
Lux Auto Brightness:-
Go to Lux settings
Tap on Sample Collection
Tap on Select light reading source
Select Camera
Then get back to main settings menu
Tap on Mopdify linked samples
Tap on Luma TAB
Tap on ADD, set brightness (yello bar) to 4% Luma value to 1 and press ADD
Add 3 more links with these values= 35%-70|100%-80|50%-120|
Exit Lux
Tasker:
Open Tasker, tap on Plus Gign(+) on main screen
Tap on Event
Select Display in Event Category
Select Display On in Display Event
A blank screen will appear, do nothing just press BACK Button
TAP on New Task +
Enter Name to task or just tap on tick
A blank screen will Appear, tap on Plus Sign (+)
Select Plugin from action category
Select Lux Plug-in
Tap on Edit Button
Scroll Down and Tick in front of Refresh Backlight brightness? Under Force
Press Done, then press back and back again
Exit Tasker
Thats all work to do, now your dvice have Auto Brightness feature:silly:
To test, just press power button and lock the screen and then cover front camera with finger and press power button again, screen will Light up wait 1-2 seconds, Screen brightness will reduce, remove finger, lock unlock screen and brightness will resume to normal.
I have tested this for full day on my L9 and got no any battery drainage.
You can modify Linked Samples Values to your comfort zone for batter sample values you can also search other XDA forums.
Guys try it and let me know how you feel
if you got any issue please post, I'll try to solve it (Coz m also new to TASKER & LUX so may be it will take little bit time to Solve:fingers-crossed
EDIT: You can uncheck "Presistent notification" in general settings of Lux Auto Brightness, If you think it is draining your phone's battery. This will also disable the annoying Lux icon from notification.
HIT THANKS IF I DESERVE IT
Another mod we miss in our L9 just got fixed.
thanks for sharing
i'll try it as soon as i can and report back.
Is this battery hungry workaround ? Two apps must run in background so they must eat battery .
Is it possible to have a refresh .. for example every 10 minutes camera will check light to set brightness?
Found it's in lux settings!

No, I have tested this yesterday for full day and haven't noticed any battery drainage coz of these apps. According to me, besides draining battery this MOD should save battery by adjusting it according to Ambient Light.

Yes Mr.Brown, you can set automatic refresh in general settings, but I'll never suggest you use automatic mode, it could drain your phones battery.

Yes bleuwavem you are absolutely right, that's why I am using tasker to initiate refresh process on display on. If you use lux individually then it will slow down your phone and drain the battery. In my tutorial actually lux is not running in background (if it is running you can kill it). Tasker plug in triggers it to refresh the brightness. Coz i have used it for hole day and currently using, I have not face any issues with device performance. If anyone body faced any issue can post here i'll try to solve it.

Click to expand...
Click to collapse
in which condition you want set your brightness 40%. Like if you want to set brightness 40% in normal day light then, when you are in normal day light, go to Lux, tap on modify linked samples, tap on Luma. Here you will see Current Value: with some digits showing. Now here hold your phone in normal light and click on "tap to refresh". it will say reading for a second and then it will show you a value, mine was 118. Note that value. Now tap on add at the bottom. In "Add custom link" box, drag and adjust brightness (Yellow Bar) to 40% and in Luma enter value you have noted. then tap on Add. thats all, now your normal daylight brightness is 40%.
Try it:highfive:
My device works just wake mod only....i do not understand why need tasker app, works without
Noob Question: Why does a lux value of 120 set a brightness of 50% in the tutorial? I've set it to 100% for now till you reply.
Great solution OP! Also, why do we need tasker to force display brightness when there is a setting for adjust brightness on wake in the lux settings? Is it because it doesn't adjust it sometimes?

Yes bleuwave your right, I used Tasker for two reasons, first as you mentioned Lux's auto brightness Don't works some tims, so tasker force it to adjust. Second reason is this that using tasker you no need to keep lux app running in background, coz if we keep it running in backgroung it will slow down phone performance and drain it's battery. Using tasker you will never miss auto adjustment

i have set 50% Brightness with value of 120, coz 120 is normal day light reading, so in normal day light 50% brightness is good enough to see the screen. 50% brightness is also no drain battery.
Yes this behave of lux also amazed me. it shows light reading value 80 in direct sunlight, in shade it shows 120. But the settings i have done, are working like charm even in sunlight also. as per my observation reason of low reading value in direct sunlight may be auto brightness setting of front camera ....What do you think about this..
Thank you very much....now my phone has auto brightness

Yes sebx its strange, Stock kernel may be an issue for this. I will suggest you to change some settings in Lux, keep every thing disabled in Lux settings, because Tasker is enough capable to run its services automatically and keeping everything disable in lux will reduce battery consumption also, so change setting and try it again.
