Auto brightness isn't working all of the sudden on the Jelly Bean OTA. It was and now no matter what I do once I unlock the screen after hitting the power button the screen will go all the way to it's dimmest setting. It doesn't matter if I have auto brightness turned on or off and any toggle widgets don't work to change any settings. It's really annoying. Anyone else having this problem?
The problem I am having with auto brightness is over sensitivity ... the screen brightness changes at an incredibly annoying pace! I shot a video to post in the private Motorola soak test forum, but I got very little response to it - seemed like I was the only one experiencing it.
Sorry for the blurry video - shot it real quick at work...

Well I'll be!!! I figuured out what was wacking out my auto brightness ... thought I'd post it to see if it can help you.
I've always gone into "Developer options" and turned off both "window animation scale" and "transition animation scale". I returned those both back to the stock setting (.5x) and no more wackiness!

Does anyone know how to fix the dim problem when Auto Lock on? I change the registry Auto Lock from 0 to 1, after that, my back light is not adjust able, it is off all the time.
I had the same probelem. I just ajusted the backlight option Turn off backlight if device is not used for to off.
Start>Setting>Power>Advanced tab and than uncheck that option.
Now the screen will not dim and so it will not stay dim after unlock. I know it's not the best solution but it works
Not a ROM Development issue.
Thread Moved.
Thanks

Okay so I discovered that Auto brightness in CM7 is messed up so instead I am using manual brightness setting. So far so good, but when I use Google navigation, after a while the screen dims to lowest brightness and wont go back to my brightness till the navigation app speaks next instruction and then it dims again after a timeout.
Anyway to turn this annoying behaviour off?
Does changing the screen timeout setting help?
The one under Settings > Display > Screen Timeout is the setting I'm reffering to.
No, that only affects the screen turning off. It remains on, just dims to lowest brightness
Give this app a whirl. You can select an app and while in the app you selected (navigation/maps/whatever) the screen will never turn off. I don't think it will dim either.
You have to use navigation thru car home to prevent that.

It's always too dark. Any way to mod this? I don't really want to manually adjust, as that is tiresome.
Seemed to work better on my old p1000.

I did a kies update. Seems to be worse now. Too bright in the dark and too dark in the light. Also slow to react to light change. How difficult can it be for samsung to setup auto brightness. I actually think my old p1000 is a better tab in many ways apart from the 3d speeds..

I wonder if this is because of a low quality light sensor. My Motorola Atrix does a pretty good job of regulating brightness automatically, except even that one is still too bright in the darkness.
For now I just make manual adjustments to the brightness on the tab, but thankfully the adjustment slider is right there on the notifications pop up so it only takes a second or two to make an adjustment.
Yes I could do manual adjustments but when I go outside and it's very bright I can't see the screen and this is where auto brightness needs to work well, which it doesn't and it is far too slow to change when I really want to take a quick pic, it just fails as I can't see the camera app for about 5 seconds.

You may want to uncheck the auto adjust screen power box that is in Settings > Screen. I notice that tends to darken the screen as well, even with auto brightness disabled. Screen mode (dynamic, standard, movie) also affects the color temperature of the display which may give a darker tone. Try the different modes and see if that helps. I notice movie mode gives a warmer look to the screen where standard seems cooler.
well , are you using screen protector ? maybe its the cause ? anyways i don't really like to set it at auto as the HC brightness is SUCK in many ways ... i like to adjust it as i want .. so live with it until samsung do something .

Unchecking that box made a huge difference. Thanks.

Yes this does seem to improve the brightness a little bit.

New Auto Brightness App called Lux
There is a new app in the Android Market called "Lux Auto Brightness" (I am new here so cannot post links but just search the market for Lux) that is by far the best Auto Brightness App I have seen yet. It is hands down better than anything that comes with stock Android. I have installed it on my Tab 7.0 Plus and it pretty much solves all of the issues/complaints I had with the built-in Auto Brightness. I really love how you can change the preset backlight level (for any light condition) to one that works better for you and once changed, the app will use that backlight level instead of its preset. This is a paid App but only cost $1.02 and lets face it, $1.02 is a very small price to pay for Auto Screen Brightness that works (no, I am not the author of the app). If you are going to install it on your Tab Plus 7.0 just ensure that you turn off the built-in auto brightness as well as unchecking the "Auto adjust screen power" setting under the Android settings/screen menu. Below is the description of the App from the Android Market...
Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If, for example, you step into a dimly lit room, Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.
Lux provides the option to automatically adjust the backlight at fixed intervals (periodic mode), when a change in environment is detected (dynamic mode), or when the phone wakes from sleep. It's also possible to adjust the backlight manually. Simply disable automatic mode and you can use it like a traditional brightness tool!
Perhaps the best thing about Lux is that you can teach it how to behave. If the backlight is too bright or dim for your liking, simply open the provided Dashboard, adjust the brightness slider to the level you desire, then hold the link button. Lux will use this new 'link' as a reference in future.
★FEATURES★
→ Custom auto brightness.
→ Sub-zero brightness to make reading in the dark significantly less irritating.
→ Battery efficient
→ Handy brightness widget
→ Option to use the camera to read in ambient light.
→ Power-user settings such as choice of interpolation, sensor debugging, and linked sample editing.
→ Backup to SD.
→ Customisable data filtering for phones with inaccurate light sensors.
→ Gradual fade effect for backlight adjustments.
→ Astronomer mode adds a red filter to the screen to preserve the eyesight of stargazers.
→ Jitter control to prevent constant small changes to the backlight.
→ Night mode, to change the colour temperature of the display for comfortable night time viewing.
→ Add app specific exceptions via compatibility mode
→ No ads, or other nuisances.
Note: Please disable other brightness apps before using Lux. This is still BETA software. The author is not responsible for any issues caused by using this app.
Useful app thanks.

Hi everyone,
I've been having rotation problems with Power Toggles so I'll have to stop using it. (It's caused my screen to not rotate and default to landscape orientation and I've checked all the screen orientation toggles)
My question is that under Settings -> Display, the Auto-rotate checkbox works like expected. What does the Auto-rotate option in Accessibility do?
Are you referring to Quick Settings accessed from the notification window?

Not the tiles themselves but under Settings ->Accessibility, then Auto-rotate Screen. What does that option do exactly? I dont notice anything but I'm worried if that is breaking my Power Toggles
I know that setting, just not sure what 'Power Toggles' are. Auto rotate screen with automatically rotate the display when tilted sideways. This does not apply to some apps as they are made only in portrait view and will not flip. One big example is the stock launcher, it will not rotate.
Is there a way to have the Ambient Display show notifications, but not the lock screen? I like seeing that there is a notification while the phone is laying there, but I hate having a long scroll of email and other things showing once I wake the phone.
Second, is there a way to adjust the lock screen time out? Seems to default to like 5 or six seconds. I would like to lengthen that by a bit, but don't see a setting.
Thanks!

You can turn off lock screen notifications in:
Settings - Security & location - Lock screen preferences-on the lock screen
I don't know how adjusting that setting affects Ambient display though. You should experiment with it.
There is no way to adjust screen timeout on the lockscreen or Ambient display.

Yeah, I shut off notification on the lock screen but it also turns off the notification icons on the ambient display. I like those on, just not the ones on the lock screen.

I guess the definitive answer is: No, you cannot have Ambient display notifications on and lock screen notifications off.
