Cyanogenmod Brightness Settings - Thunderbolt Q&A, Help & Troubleshooting

Hey guys,
I'm having trouble understanding the autobrightness settings in CM7. I'm fine with the level of brightness it makes, it just takes too long to kick in. I've tried messing with the settings, but to no avail.
I use widgetlocker and worked hard to make my lock screen look cool. I can barely see it whn I turn the phone on because of the brightness.
Any info would be greatly appreciated!

for some reason the auto bright function on all AOSP roms is screwy. i just disabled auto and manually raised it up enough to where its acceptable to me.

Eh, I just set up my own brightness profiles in Tasker.

I would try doing what this guy did. The settings there should give you fairly decent auto settings.

[Request] Night Mode

I was wondering if someone could create (or if there already is) an app that will dim the screen a lot more than just setting it to 0. I work late hours and come home, just wanting to unwind and play some solitaire. I'm blinded by the screen. I know that there are night/clock apps that can do this. Thanks!
I second this request. The screen is quite blinding in a dark room. A night mode would be nice too have.

I would pay for this app, blows my mind how they could make a phone that can't dim lower. Even when setting brightness to 10 with Dimmer it's a real pain using this phone in the dark.

I would also throw down some of my hard earned dollars for something like this, i want to preserve my battery and the dimmest setting isnt making me feel happy about things
Why not just slide your finger across the task bar from right to left and it would lower the brightness to the lowest setting. To brighten go the other way.
Way easier than another app.

Thanks, but not what I was talking about. I'm talking about lowering the brightness past that for nighttime usage. I know it's possible; I have a bedside app that lowers it way past the default.
BTW, that trick only works with Auto Brightness off.
yeah this would be nice. also, having those cool filters like on CM6 would be nice too. the red filter is great for checking your phone in a dark movie theater.

SOLVED [Q] screen randomly goes full brightness.

As the title says my GFs 10.1 will go full brightness at random times. Only way to change it back is to go into setting. The slider is all the way down but have to slide it to full then back down. Any ideas guys?
The fix is: Go TO SETTINGS, SCREEN, AUTO ADJUST SCREEN POWER, UNCHECK. Thanks bd85!

I have had this issue as well when using auto brightness function. Only when viewing photo albums. Very annoying. I no longer use the auto brightness function now. Little issues like this drive me crazy. Add this to the keyboard lag and other small issues and i start to question the purchase.
Thankfully i found this site to help me realize its not just me...misery loves company. Lol.
Have you guys tried to shut off the option in setting that's can analyze the screen color and more and the adjust the screen for power savings.
I have noticed what you are mention. And it only appears in movie's because the picture change often so the tab tried to compensate the colors often.
Go TO SETTINGS, SCREEN, AUTO ADJUST SCREEN POWER, UNCHECK.
And I am not talking about the auto brightness that you can access from clicking on the lower right part of your screen

That seemed to be it. Didn't think to check that since the Xoom doesn't have that setting. One thing i wish the xoom had was the whole different wallpaper for lock screen thing the 10.1 has.

Disabling Browser Brightness?

This is really bugging me, is there a way to disable the browser brightness settings? Our can I make it synchronise with the main display brightness?
I don't use automatic brightness and rely on the switchpro widget on my home screen to adjust the display brightness on the fly. It's really annoying to see the monitor changing brightness when I switch between an app and the browser, or even going through the bookmarks page within the browser itself!!

What? No one is having the same issue?
I want my screen brightness level maintained throughout various apps/homescreen/browser, is there a hack for this?

The original Galaxy S and its variant all had this "feature". I HATE IT. 3rd party browsers are too clunky and bloated, but geez. Having to change the brightness TWICE every time I want to change it really blows.
It's not that nobody else has this issue, it's that (for some reason) nobody with the skill to fix it cares to do so.
count me in as 1 of the people that is tired of having a separate brightness control. I can set my brightness way down and in the middle of the night I turn on my browser and boom! a super bright light is in my face.
Frustrating.
Of course I have the issue as all others. But it doesn't make an impact as I always on Auto Brightness
Regards.
+1
Please has anyone had any luck with this. Keep trying others and ending back with stock. Just wish it used system brightness and that it let you close a window even if it was the only one.
Anyone had joy with either?
Thanks
Another one for 'Tasker' to solve
Download 'Tasker' from the market (£3.99 I think?)
You can then create a profile so whenever you open 'internet' tasker will set the screen brightness to a setting of your choice.
Simples
(believe me this is only the tip of the iceberg with what Tasker can do)
Tasker does not have a setting for Browser Brightness.
Hi thanks for the idea, but I have been trying to find a way to do this using Tasker without any luck. Tasker already controls my Screen brightness. Far better than Auto. But the Screen Brightness and Browser Bightness are two seperate settings. I can only get Tasker to adjust the Screen one.
Still if anyone has any ideas, please. It drives me nuts when I turn over at night to check something on the web, then get blinded by a full brightness broweser on a dimmed phone.

[Q] Screen in Camera app often very dark

Hi
my woman got the Galaxy S2 and has a problem with the camera app. The app shows a very dark screen like a maximum power saving mode. The rest of the apps are Ok. It can help then if I turn off the automatic brightness of the screen and the energy saving settings and turn them on again. But after a couple of days you have to the same again. So she is a bit p...ed about that. Does anybody of you have an idea how to get it stable bright?
BR MArtin
'my woman'...lol.
Anyway if you go into the camera app settings, scroll to the bottom and click 'reset'. Maybe your exposure settings or contrast etc were changed somehow. If that doesn't work...might be something up with the camera, or even some rubbish on the lens. You could just take it back and get a new one..
Never had problems with that, but all I can think of is that the illumination-sensor next to the front-face cam is dirty?
(less light coming tru makes everything darker?)

With the settings in the picture everything is ok. The picture taken with the camera are ok. Also the Sensor is ok as it is working fine everywhere else. Any other ideas?

Anyways... So I you have the app (camera) open.. Do the bars (with the icons in it) also seem dark or do they look (normal)bright?
Sent from my GT-I9100 using XDA App
Yes everything is dark must be some problems with the energy settings or whatever
BR MArtin
Let me eliminate some causes:
- you've unchecked 'automatic screen brightness'?
(@settings)
- you've tried maximizing brightness manually?
- you've rebooted throughout the process? (giving the phone the chance to apply it's settings, sometimes all it needs is a reboot)
Let me know.
Sent from my GT-I9100 using XDA App
Basically I tried evrything you said with unchacking and Checking the automatically settings and also the additional Energysaving settings it gets back fine for some days but then it changes back to the dark setting unless i check and uncheck the boxes again. So it seems not to be a stable sollution. So I search now for a sollution that the camera app always runs with maximal display brightness
I've tried about everything then.
I ran some tests on my own SGS2 but I can't emulate the dark bars.
Not even by holding my finger over the light-sensor.
But I guess it's like this and I DO NOT know a fix for it: seems like the phone is learning that you don't use the camera much. So if you do. It will automatically go into power saving mode since the priority for battery-use is for system instead of cam (due to low-use)
So the only last thing I could think of, is that you've enabled automatic power saving?
Uncheck it and take Juice Defender as your 'battery saver' fixed alot of issues with brightness going up and down for me(very annoying) never goes up and down for me anymore!.
I hope this is of good help.
Sent from my GT-I9100 using XDA App
Ok will try that with Juice Defender.

I have write me a task with Tasker witch put me max sensor light and auto rotation on when I open the cam. after closing it revers to the normal state! ,-)
I think I had the same problem as you.
In the camer app > Settings > Outdoor Visibility > ON
(it unfortunately resets everytime I exit the app)
Hope it helps
I tried with the Outdoor visibility but this seems to change the colors of the screen and not the brightness.
You are right, that does not work. I was at work when I tried this and it seemed to make the screen brighter, but outside in the sun light it does not make any difference. So I have the same problem as you lol
It's not his screen or image. It's the gray bars on the sides that he means.

I tried the following thing and it's work :
1. Uncheck auto brightness
2. Make the brightness 100 %
3.Check again auto brightness.
On my phone when i made this the brightness on the camera is 100% and is not depending from auto brightness.
this totally worked! seems like within the camera app, there is no auto-adjusting of brightness and it always defaults to what the last brightness setting was set, regardless of auto-brightness status (checked/unchecked).

Screen Brightness Issues/Thoughts

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.
