I just installed CM7 stable version yesterday, everything goes smoothly except for the autobrightness function. Whenever I turn my screen on, the first time it always very dark, although perceivable but it's like the autobrightness is broken. Yet, when I immediately turn off the screen and turn on again, it's bright like nothing happens.

try turning off "screen off animation" it will fix it. it a known bug.
please refer to this thread Numerical explanation of the CM7 automatic backlight settings
Byrong does a really good job explaining what the auto brightness settings does in CM7.
By default CM7 auto brightness doesn't work very well, you need to configure it to your liking using the options described in that thread.
Use the status switch toggle the autobrightness!
Hi,
My automatic brightness setting just leaves the brightness exactly on what it was before. E.g If I manually put slider to max, and turn on automatic brightness it stays on max (even if in a dark room), and if I put it minimum and go outside or shine a torch on it, it doesn't go higher at all.
I'm not sure when this first started happening, it always used to, I'm running ARHD 5.1.11 (a ginger-sense rom), with golauncher ex. I can't think what's causing it. Elixir says that the sensor is working (the numbers adjust as I put light on the sensor).
Any ideas would be much appreciated.
Not a direct fix for your problem but I downloaded OnOff Widget Pack. This has a great brightness control. Running Auto Brightness for most situations seems to be a drain on the battery.
I've been running LiteROM 0.9.0 for about a week and I've noticed a couple of issues with the rom and I'm hoping someone could give me some advice on how to fix them.
1. QuickPanel does not update. For example if I toggle the data via quick panel, the data connection will turn off but the icon will remain the same.
2. Brightness settings cannot be adjusted. The brightness will instantly revert back to the default settings whenever adjusted. Cannot use auto brightness.
3. Lock screen alarm icon will not disappear whenever the alarm is turned off.
The only way I've found to get rid of these problems is to reinstall the rom with a full wipe. Even this will only solve the problem temporarily as the problems will return after the first restart and the cycle repeats.
Hi guys,
I have just managed to update my Nexus 7 2013 to 5.0.1 (After lots of problems though, see here). The problem is that "Adaptive Brightness" feature doesn't work anymore! I mean by turning it on, the brightness level sets to highest level, no change in different ambient light situations and the brightness slider doesn't work at all! On past versions I could change the brightness level even with Adaptive Brightness turned on and the sensor was working fine, but now it is only changeable when the feature is off! any idea?
Try to refresh /boot and /system partition within fastboot.
I already did (please see the link in my first post), but still the same!
Wipe cache
try to wipe cache or restalling
Is the front camera working?
Thanks guys for your replies,
After several restarts, it works again like a charm!! I'm happy but confused!
Hi everybody, I recently updated my Eonon Androud HU to 5.1.1 using the first 5.1.1 custom ROM listed here. The DSA Prerooted ROM. Thus far it's been functional and fits my needs over the Malaysk ROM. However this ROM has some sort issue with it automatically dimming the screen to low, even though it's been set to 100%. When sliding the brightness slider to 100, the screen will still dim on its own, regardless of the adjustment still being set at 100%. I have gone through all the settings and found nothing that can help me. The display submenu only displays the option "Brightness". Which is just the standard slider to adjust the brightness. There is no option for Auto, Low, Bright, etc.
I've downloaded some apps to control the brightness to see if that would help, but something on this ROM is overriding any brightness apps from working. I even tried installing an xposedMTC module as it had an automatic dimming option, hoping to deactivate it completely but no luck. The way my car works is my headlights have an automatic DRL. When I turn my DRL's off, the headunit seems to activate it's full brightness, until I turn the automatic light control back on which turns on my DRL's, then the screen goes dim again. It's as if the headunit is going by the whole "Oh your headlights are on, it must be dark outside. Let me adjust the brightness to low for you".
Any help would be appreciated. I hope it's a simple fix. Thank you!

That's one of the main differences between Malaysk and DSA. DSA told me look out the window and figure it's night time. Secondly he told me to go to max at least two or even three times in a row. It will then STAY 100% bright till you reboot.

Whoa, thanks for the quick reply and useful information. Is there absolutely no way to bypass having to do that method? As that would be a chore doing it multiple times after exiting and entering my car multiple times a day. Maybe a simple build.prop edit possibly? Just naming ideas.
There is... Mtc manager has settings in it for brightness settings due to time. You can turn it off there. This didn't work for me so I went another route with changing some file. Its all detailed in the thread as to how.

You could disable brightness control entirely or just alter the brightness levels.
It's in file /system/etc/install-recovery.sh - at its end, comment out all 14 lines after comment line reading "#Brightness control (last, always)", in order to disable the algorithm.
OR, change line reading "nb=5 ### Night Brightness ###" to a different value for the night brightness (nb), eventually equal to day brightness (db, on next line).
Use a root explorer, or edit a copy of file on PC (with notepad+ if on Windows) and copy it back - with a root explorer or manually, if you can. File mode: 0755, owner & group: root:root.
If script /system/etc/install-recovery.sh gets "damaged", you must reinstall the firmware, but with NO wipe all, so fairly quickly and no loss of settings and apps.
Editing of script could also be done with @devilsoft app (with a name I can't recall).

Hi @brian117 !
In fact, there is a simple fix I found lately.
You need to enter factory settings first.
Go to SETTINGS -> Factory settings -> enter code: m123456
When you're there, go to last page, and tick the "Key light" option.
Now press "Apply" and "Exit". Confirm reboot.
It worked with me - now the screen has full brightness regardless of the car lights on or off (in Poland we need to have the lights on whole day, as well). Now you can use a software dimming, like MTC to auto dimm the screen according to actual day time. I did this. Works like a charm! (I set dimming after sunset to 75% brightness)
