there is an option "auto" for screen brightness. but when i selected it, the screen doesn't dim at all. i looked all over my tab and i didn't find a light sensor. does it mean a100 cannot auto-adjust the brightness?
Yes it has one. In landscape, with volume at the top, it is right above the front camera.
I remember having sluggish dimming when I was on the stock rom, I did a factory reset and it made it better. Try putting it in auto, restart the tab and then take it outside and you should see it brighten up, and then dim when you come inside (if it is working).
It also never goes full dim, its light modes are pretty bright, I think to offset the viewing angle issue it has.

So the Lumia 900 dims the screen based on white pixel percentage (for battery) like the Focus and Focus S. Is there an extra settings option to disable this like on the Focus S?
What I'm asking is if there is an 'Extra Settings' category in the settings menu with a field called auto display intensity (like on the Focus S). Thanks.
I'm not seeing it. Today starts my 30-day trial to see if it can pull me away from my investment into Android and my HTC Desire..
I think you can just turn off the Auto brightness. There are no other display settings like on the Samsung WP7's

Yeah, the screen looks a little dim on the auto setting. Someone said that is the way AMOLED screens are. When you disable the auto and change the setting to high, it looks great. I just wonder what the effect on the battery life will be.
I recommend disabling auto-brightness and setting to medium. I personally use low indoors and medium outside. Auto-brightness should be off to save power.
The original poster is correct. Even on Bright with auto turned off, the message area is grey'ish, but white everywhere else seems fine. I went and tested it with the Focus Flash, and it had the same behavior, except when you turn off the "auto display intensity" (or words to that effect) it goes white. I think the Nokia has the exact same behavior, except that we don't have a control to turn it off. I'm keeping my screen on bright to alleviate this, and I know it's hurting the battery to do so.

Auto brightness = dims based only on the ambient light sensor. Auto display intensity = dims based on % of white pixels on the screen.

Do you know of a way to switch the Auto Display Intensity?
Is there a fix to this? I got my Lumia today and when I opened the browser and loaded Google it seemed very dim. Even if you change the background of the phone to white instead of black, it looks almost grey and dimmer than some of the other whites on the phone. Is it a bug? Should I replace the phone for another one, or are they all like this?

"Feature" not a bug. Samsung presumably provides Nokia the AMOLED panel which has it programmed into the firmware. Samsung modified WP7 on the Focus S to let you disable it.
Auto Brightness is meant to work in a way that when an external light source is there the screen will go bright and with the source gone it will be normal. I was just testing mine with my backup phone's (a cheap Samsung, which has a LED torch) torch and each time I put it near the Note 2's sensor (about 6" distance) the screen goes up very bright, that's okay, but the problem is when I turn off the torch the brightness stays the same, i.e very high, it won't go back to normal unless I press the Power button to turn the screen off and re-press it to awake the phone. But it kinda works when I am browsing net on it having my room light on, and then it goes back to normal, or dims out when I turn off the light. But the issue is occurring when I am placing the torch near it's sensor.
Have any one of you tested it. Is it normal?
TIA.

I have the same issue especially after the new update I don't know is this a problem in sensor or software?
AW: Does your 'Auto Brightness' work perfectly?
I just tested it while reading this and my screen dimmed immediately after turning off the light.
Android 4.1.2 (DMB2)
Edit: You can see the current measurement of your light sensor by dialing *#0*# and choosing sensor.

My autobrightness
My autobrigtness is slow to adapt, in some cases, when i go out on direct sunlight i have to wait almos 10 or 15 secs to become brighter.
I think that with older firmwares was faster...
Anyone observed, even with auto brightness mode, when you move the brightness bar from low to high the brightness increases a bit.
So, if I have the brightness in Auto mode and put the marker in high end, does it mean the brightness will be set with a value greater than normal-auto brightness for all lighting conditions?

Exactly.
Love the marker to be honest. Something that annoyed me about my Nexus 7. Sure, there might be third party apps to set that, but so awesome to have it out of the box.
My auto brightness doesn't work perfectly, but I still give it an A for working correctly about 90% of the time. It is also the best device compared to many others I've had where auto brightness was basically a joke, even nexus devices.

Works good for me most of the time, just did what you did and after around 5 seconds the screen dims itself again. Bare in mind in a brightish room it can be difficult to see the screen change its brightness as it does it rather slowly. However I tend to turn auto brightness of as it's never quite how I like it (I like 100% brightness in a well let room, on auto it seems to only go to max 80%, and 100% only when outside). With the Note's ridiculous battery life I don't find it a big deal, I am still able to mock iPhone 5 users when they are turning brightness all the way down and mobile data off etc when it gets toward the evening
Same pronlem here

Mine dims again when I lay it down on ie table or holding phone in that position (like it was laying on flat surface). When I'm holding phone in any other position it won't dim.
Tested on 2 n7100's both running stock dmb6.

I have the same issue exactly the sensor works perfect when the phone is in horizontal position if I tilt it or hold it in vertical position it doesn't dim unless I closed the screen and opened it again I don't know the solution for this weird problem?
That's so that you don't accidently change the brightness. We tend to keep hands near the area the sensor is.

I've noticed on my Nexus 7 that the screen will alter the brightness pretty frequently even when I'm sitting in the same place and the ambient light level around me hasn't changed. It will dim a little bit and then brighten a little bit several times while I'm just sitting there reading. It's most noticeable on a white background but it can be seen at other times too.
I'm pretty sure I'm not blocking the ambient light sensor with my hand unless there is a sensor on the bottom of the device. I've also confirmed that there isn't anything wrong with the screen by turning off auto-brightness and the screen no longer brightens or dims after that.
Anyone else think auto-brightness is too sensitive?
It could be anything. I'm sitting in a room right now where a window is about 3 feet behind me and about a foot to my left. If I rotate my device just a tiny bit it towards the window, it becomes enough to brighten my device. Then if I rotate it back to its normal position, the brightness goes back down. It's pretty sensitive.
Are you in a room with windows? Perhaps the sun is going behind a cloud or something and coming back out.
Yes there is a window but this was at night and I had a lamp on beside me. I was being very careful not to turn the N7. At this point I've just turned off auto brightness because its distracting.
Under display settings, there's this "Auto Adjust Screen Tone" that confuses me. Looking for the explanation as for what it does, I found it supposedly plays with the screen brightness based on the on-screen image, but it's very vague. What's the point of having both this and auto brightness? How do they work together?
Setting it on and off shows absolutely no difference. Does it really save battery at all?
Doesnt really do much for me either. I think its for a better accurate brightness level when you turn on auto brightness. When you turn on auto brightness and the adjust screen tone I think that would mean that the auto brightness would adjust its brightness by the sensor next to the front camera and the auto adjust screen tone would adjust to the image being displayed makeing the brightness best for the envrioment your in(how much light is in your room). Lets say your in a dark room and your trying to veiw a dark image, so the screen would get brighter even if the sensor is saying "theres no light here" based on the screens image. Thats my guess and someone correct me if im wrong. Idk if it saves battery but I just adjust my screen brightness manually.
It should actually be an attempt to match the color temperature of the screen to your environment. For example if you're outside it'll shift everything more blue (around 5,500 degrees kelvin) than if you're indoors with a "warm white" lamp lighting the room (closer to 3,200 kelvin). All this in an attempt to make colors appear more accurate wherever you are. It's safe to assume it uses the camera to read the colors of your environment, I'm pretty sure the light level sensor only measures luminance (brightness). Hope this helps.

^^^ that's what you'd think from the name, but if you read the description it says adjust display brightness based on image on screen to save battery. So I think for example if you have a mostly white screen it'll reduce the brightness. If done right, you won't notice it because it'll still look plenty bright.
Has nothing to do with temperature. I wish there were a feature for that.
I'd try it for a while to see how it feels. Probably a good feature.
When I'm in a dark room, I like my phone very dim. I manually turn the brightness all the way down, but when I turn on the camera the brightness goes way up to blinding level. Any way to prevent that?

Just tried it on mine. With the brightness set almost all the way to dim, turning on the camera move it to about the halfway point. If I turn off auto-brightness, though, it doesn't change when I open the camera.

I guess I can work with that. I thought I had auto 'off', but I guess it was on auto.
