I've noticed with my GNEX that it seems like all of the sudden it won't auto dim. When I unlock the device it will brighten if needed, however if I walk into a dimmer area it will not auto dim. Is this the normal behavior for the light sensor?
I'm used to my Xperia Play which would constantly adjust the screen up and down.
My auto-brightness setting sets the screen brightness lower than the lowest actual brightness setting regardless of whether I'm in light or dark.
There's a fix for it here: http://forum.xda-developers.com/showthread.php?t=1377410&highlight=auto+screen+brightness
I haven't tested that out though.

Yea I was worried maybe the brightness sensor was not working since. Turns out my wife's droid 2 with CM7 acts the same way. Lowest setting until you unlock at which time it only increases the brightness, never decreasing.
Does anyone know what light levels the light sensor takes? I came from Droid X where the light sensor only sense 4 values. Does the GS3 light sensor only take specific values or the whole interval? I want to know cause my auto brightness is very low when I'm outdoor and not sure which light levels to fix.
Are you sure the brightness is low when you're outside?
AMOLED screens usually aren't very effective in the outdoors, I have to crank the brightness all the way up for it to be visible for example.
and iahucarn
I'm sure it's something to do with auto brightness since the screen is much brighter when I turn off the auto brightness and turn the brightness all the way up. It might be a bug in my rom, I'm using CM10.
I set my watch to use auto brightness. In a dark location, like movie theater or dark room, the auto brightness is not working properly:
- when I receive notification, the watch screen turned on at the full brightness. After about 2 seconds, then it either turn off the screen or the brightness reduced.
- when I wake up the watch manually, same thing happen.
Anyone experiencing this?
I usually see the opposite, where in a dark room, it comes on so dim that I can 't even see it, then brightens after a couple seconds. However, your general point is right on... the auto-brightness definitely needs some improvement.
Hmmm...That's interesting.
Really tick me off when I just woke up and the bright screen blast my eye. I am using the watch with sleep android app, but I think I'll forgo that.
Auto brightness in dark situation for me is terrible. It is even dime than level 1 brightness. I can only see time, but can not read notification clearly. I change to level 1 setting, it is great. And save lots of battery as well.
Moto 360 Brightness
Try the application "smart brightness for moto 360" from the Google play. With this application you can set a minimum brightness and better view in low light environments.
With the minimum set to 20% and auto brightness on you will get better battery life and better experience in dark situation.
I leave my phone set for Adaptive Brightness.
First, it's annoying that setting the manual brightness to max and then turning on Adaptive Brightness means that I can't achieve super dim display in dark.
Anyhow, so I leave my phone set to Adaptive Brightness all the time.
And it usually adjusts my display bright or dim(ish) as needed.
Then randomly it'll just go to the absolute dimmest setting and stay there even after a reboot.
I have to toggle Adaptive Brightness off and back on again.
Anyone else seeing this behavior?
I think it's time to give Lux Brightness app another shot.
Hopefully they've worked out the bugs since the last time I used it.

I've not had any issues with mine, do you have a tempered glass screen protector that covers the sensor on the front of the phone? It may be detracting light confusing the sensor.
Nope, no covers. Nekid phone here.
This is my first AMOLED screen phone and something I think I may be noticing that maybe you guys can help confirm or deny about AMOLEDs vs LCDs, is that at night when turning the brightness down (way down, like -50 in the Lux Dash app as an example) results in getting the screen to a point where not bright enough to hurt your eyes at all but the blacks are too dark. So there's no real ideal brightness setting in a dark room that equals no eye pain but still allows you to able to see everything on the screen. Or are my eyes just too sensitive and most other people don't need to turn it down as much as I do and therefore don't have this problem?
You tried night mode
Lux is garbage. Factory adaptive brightness and still being able to use the brightness slider to allow on-the-fly adjustments is far superior - it works perfectly on this phone. And in a pitch black room, with adaptive brightness, setting the slider from 0-25% results in an extremely dim screen (1-2 nits) will information still perfectly viewable. Blacks may have uniformity issues, but that is the nature of OLED panels since it is extremely hard to control voltage at near-black levels when the brightness is extremely low.

Amoled displays, when used with automatic brightness adjustment, have a small problem - when you are viewing them in the dark, they appear too dark. Their contrast ratio is infinity, which means that dark colors are basically zero luminosity or close to zero. A lot of internet imagery is calibrated for lcd displays, so when you lower your phone brightness to make the brightest parts viewable on an amoled display, the dark colors become too dark and blend together. This is especially true when you are viewing a screen in a dark environment. There's nothing you can do but increase device brightness by hand when you are using automatic brightness adjustment and viewing in the dark,

You do realize that Adaptive Brightness simply changes the brightness of the screen in response to the light sensor reading?
In other words, the phone doesn't care about your preference - it will change the brightness to preset levels.
On Samsung phones, this situation is far more intelligent. The phone still uses the light sensor to adjust the brightness, but the phone also applies a user preset to augment the brightness - when you slide the brightness slider up, the phone will make auto brightness adjustment higher, and vise versa.

WHAT? You have it totally backwards. Stock Android, including the Pixel, uses user input to augment the auto light sensor brightness when adaptive brightness is enabled. If my phone thinks 50% brightness is appropriate, but my slider is set to 100, it will choose something like 75% brightness instead. If I drop the slider to 0% in the same instance, it might choose 25% instead. The user preference will ALWAYS be impacting auto brightness.
Samsung phones, unless it changed with Nougat, rely strictly on what the phone thinks is best for auto brightness. The user can adjust the slider with auto brightness on, but the slider is a direct adjustment 0-100% of the true brightness level, and the slider will change automatically when there is a large shift in ambient light after the display has been turned off at least once. User preference does NOT impact auto brightness unless you set it at that specific moment.

I have a Note7, Pixel XL, and LG V20. Google how adaptive brightness works. There won't be a single article that matches how you say it works.

Give me evidence. I don't care what your hypothetical "articles" say, I had the actual phones and played with their brightness settings.

If you seriously can't tell how adaptive brightness works just by using it as compared to Samsung and LG, I don't know what to tell you. It's pretty damn obvious. If I'm the kind of person who prefers a bright screen, I can set adaptive brightness to 100% and it will always be bright, but stay relative to the ambient lighting. If it's a dim room, the screen will be bright, but nowhere near 100% manual brightness. It only hits 100% manual brightness when under bright light like the sun.
Samsung's auto brightness is still very cookie cutter. If you put 2 Samsung phones side by side with auto brightness on, they will always be the same no matter the ambient light. If I take 2 Pixels, both set to adaptive, and put one on 25% and one in 75%, they will always maintain a brightness difference even when ambient light changes. Samsung phones do not maintain user preferences once the ambient light level changes. I almost never have to adjust my Pixel. I always have to adjust my Note7 because I prefer a slightly brighter screen.

What you are saying is EXACTLY THE OPPOSITE of my experience with Note 7 and Pixel XL. I NEVER had to adjust my Note 7 brightness once I set it.
I find myself constantly adjusting Pixel XL brightness setting.
Maybe they both have "adaptive brightness", but the Note 7 version was perfect, and the Pixel XL is just sh`1rt.

Or maybe you two just have differing opinions on what a "perfect" brightness setting is...
Doesn't matter how you adjust your brightness. I'm just saying that when brightness is low, blacks are darker and disproportionate to other colors.
I love Lux especially with it's profiles. Much better control and accuracy than adaptive brightness. I just wish Lux had an auto-profile switcher based on time of day. I have a day profile, night profile, and car profile.
One thing to note is that Lux allows me to bring the darkness down below 0% to negative values, which is where I usually notice my concerns. But that's what I need to not hurt my eyes at night. So I don't blame the phone or anything - just posted this article out of curiosity. The blacks are probably just turning off completely at some point when I bring the value to below 0% which I think makes sense based on the nature of OLED.
You should just turn on night mode to help with eye strain. If 0% brightness is too bright I don't think you will ever get lux to work the way you want, but night mode helps my eyes a lot.
Pixel XL adaptive brightness adapts to what you set the brightness to. If you go from 0 to 100 in a totally dark room, you notice how the screen stays really bright and doesn't go back to 0 on Pix
Many phones use auto brightness to fullly determine brightness based on sensor and ignores user brightness. If you go from 0 to 100 with an auto brightness phone, the phone will go back to 0.
Some prefer one over the other.
