Agreed buttons don't seem to work. First time I tried this the buttons actually became dimmer, now they seem to be stuck on one setting, no matter what the number is. Perhaps a CM bug?

Agree probably a bug

Is there a way to make the auto adjust more sensitive? If I go out in direct sun light it takes a couple times turning the screen on and off to get the brightness to turn up.

DitThese setting are not surviving the nightlies, correct? Just have to go and re-enter after flashing a new nightly?

Edit: just saw the post on the previous page.

No I think they stay unless you wipe

Ok could use some help here...would love to try out these changes however how do you change the values in the "Upper" column?

Pardon my n00bness with this tweak...never messed with the light sensor levels before so I'm not sure if I'm doing something wrong or not. :androidwink:

When you change the lower column, the upper is set automatically for the line above. Just enter the lowers and you will see the uppers filled in for you.

After testing this all day today, I guess I'm on the fence about these settings. I'm not sure if it's the settings or the phone's ambient light sensor actually, but it seems to run flat through a whole set of conditions and then spike in direct bright sunlight. Inside a house during the day, it's showing a sensor reading of 60/100. Inside a car on a sunny day - 75/100. Setting the same value for both of these situations makes the phone too dim in the car or too bright inside. Even outside in the shade it running a max of 100/100. But as soon as it goes into direct sunlight, it spikes to 4k+ - there just doesn't seem to be much in between.

Thanks for the write up. I was wondering how we controlled brightness settings in CM7. New to cyanogenmod, so it's all a learning curve. For myself I find your settings pretty useful. I will probably tweak my settings a bit though as it feels like it's too bright at times. That is probably just my own preference, so thanks for supplying the head start.

I would like to get an app that showed the detected lux at any given time using the on board sensor. Anyone seen or heard of such a thing. I will do a search and see what I come up with. Would be nice to get a feel of what the phone is detecting in my normal travels.

I can say this...I wish I would have read about not setting the display to 1...I assumed this would give you some sort of display as it is not 0 but I was sadly mistaken. That mistake could probably have been fixed by wiping data/cache or something but I was on the verge of flashing a new nightly anyway so I just cut my losses and started over. Live and learn...

Did anyone see more battery consumption with this turned on? As soon as I enabled auto brightness my battery was dropping like a stone. I left it for 2 days thinking it was something I was doing. Today I disabled it and there was a distinct increase in battery life as soon as it was disabled. Look at the screenshot, where the graph levels out is where I disabled auto brightness.

I will say yes and no. On days that I am using my phone inside all day my battery seems to be running the same, maybe a touch better. However on days that I am outside using my phone my battery life is not as good. However I can see my screen A LOT better. I have also found that I am getting better battery life than having the screen set at 15% and then going to MAX when I am outside and need to see my phone. I have been tweaking my phone, but it seems to get similar battery life and I don't have to worry about seeing my screen in any setting.

Thanks for the reply. I've gone back to SwitchPro with a 30-100 manual setting for now. I'd like to have the time to tweak the AB settings but I probably won't have that until this weekend.

Right. Also, it's kind of sporadic. Sometimes I would turn the phone on and it would be very dim and it would stay that way. Sometimes I would turn the phone on and it would be bright and it would stay that way. And sometimes I would turn the phone on and it would start at one brightness, but change as time went by.

Very strange. I guess I have to work with it.

I've seen the same thing a few times in the past few days. A reboot 'fixed' the problem, but it would happen again eventually. Seems to happen on CM7 as well as SSX 2.0

What I've noticed is that if I repeat the following steps several times, I'll eventually run into the scenario in which the light sensor's RAW value gets 'stuck' at whatever value the sensor read initially, and won't budge no matter how much or how little light is being presented to the light sensor. In my case (office lighting), the light sensor reads a RAW value of 100 (with 10, 3600 and 8600 being the other RAW values it will change to).

Automatic backlight -> Light sensor filter is Enabled, Window length 10 sec, Reset threshold Disabled, Sample interval 1 sec, Use Custom checkbox checked, Screen dim level 20 (default)

Steps:
1 - After reboot, wait ~10-15 sec, then unlock screen (rotary lock screen in effect)
2 - Go to the "Edit other levels" screen in CyanogenMod settings -> Display -> Automatic backlight
3- View Sensor (filtered/raw), which in my case starts off at 100/100
4- Cover sensor w/ finger, Raw changes to 10
5- Remove finger from sensor, Raw changes back to 100
6- Power button -> Reboot (normal reboot)

After several repeats of the above steps (sometimes 2-3 times, sometimes > 5-6 times), the Raw value will get stuck at 100, won't change to 10 when I cover it completely w/ my finger, and won't increase when held right up against my (quite) bright office lamp.

I SBF'd back to Froyo and went back to CM7 (also SSX 2.0), did clean re-installs of the same handful of apps I've always had installed, but still see the above behavior. Kinda weird...

Just want to give this helpful guide a bump so others may see it.

How well does this work for everyone on the newest nightlies? I'm on 35 currently and it's really squirrely in terms of certain levels of brightness in various light conditions. It's really hit or miss - as if the sensor isn't sensing the light conditions.

I guess what I'm having trouble with is the consistency of brightness.

I had that problem as well when I was on CM7. It's almost like the sensor is sticking and not reading the light level correctly. The non-advanced auto brightness worked perfectly fine, but the advanced auto brightness settings made it "stick" from time to time. It didn't happen regularly, so I just turned the screen off and back on when it got stuck on one brightness level.

I have been running 35 all day with no issues with the advanced brightness. The only time I had issues was when I tried Liquid... That ROM there was something wrong with how the averages were calculated in certain situations that would cause erratic changes, but CM7 has been consistent for me.

Bump.

Do these settings work just as well with MIUI?

Yea, they should. Miui is built on top of cm4dx, so you should get the same results.

 

[JagoX]

Ah gotcha. I'll give that a shot and see if I notice some improvements. I'm on MIUI at the moment so well see if I see any improvements.

To the people who find these settings too dim, leave the "Screen dim level" at '2' and in the "Edit other levels..." menu, change the '2' to a higher number. Then, you can use the display notification power widget to switch to the dim level ('2') when you are in really dark places.
