Auto Display goes to really dim setting sometimes - Google Pixel XL Questions & Answers

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.

Auto brightness always low

Using stock 4.0.1 here, and have always had the brightness set to auto. But it never seems to do anything? If I am in a light or dark room it is always dark, often darker than the lowest brightness setting.
I am just worried that the sensor might not be working, if the phone needs to be sent back it needs to be done soon. Anyone else with this issue? I know the sensor that turns off the phone screen when in call works, but the auto brightness might use a different one.

Auto brightness is just simply low on this device. There are some hacks in the dev section to increase it...but they don't work on my ROM.
I just started using juicedefender to adjust the auto birghtness
So auto brightness itself is broken and sensor is pry OK? I wonder if there are any apps to test it.

Simply put a bright light to it and watch the screen brighten up. The sensor is fine.. auto brightness simply is a little too conservative, probably because more people would moan about battery life than screen brightness.
My auto brightness works just fine. Sometimes I have to the screen off then on for it to adjust. Other than that, the levels are fine. I'm on 4.0.3.

How does the autobrightness function? IE Normally.

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.

Sometimes display is extremely dim.

Sometimes when I'm in a dimmer area, my display will be so dim I can hardly see it. This doesn't happen in brighter areas.
For reference, it is far far dimmer than brightness setting 1. I have the watch set to auto brightness and ambient off.
Anyone else seeing this?
Yeah, it seems that the 360's auto brightness setting is (at least sometimes) pretty aggressive in low light conditions.
Same here, and I hate that. I always have to go into the settings when the room light is dim, and switch off auto brightness and change to the 1 setting.

I'm almost positive it's a bug, the low brightness of 1 isn't too bright for very dark situations and the dimmed mode is simply too dim.
I'm pretty sure auto-brightness should turn on at level 1 (if it's dark) and then go to the ultra-dimmed mode before the screen times-out just like in normal brightness.
I don't think I've seen this bug happen in the daytime though, so it does seem like a bug at brightness level 1 only
Any solution to this problem? Drives me crazy.
Thanks

Try Smart Brightness for Moto 360. This application allows to set auto brightness with a minimum brightness to avoid a dimm screen on dark situations.

auto brightness too low

hey guys,
im having trouble with adaptive brightness since some time and i am pretty sure sth has changed there.
my screen is just to dark for the most time.
some time ago i could just increase the brightness value and the adaptive brightness would work with that (higher) value, like an anchor value.
now, by doing that, i just change the overall brightness and it will jump back after some time.
is this the same for you guys? it gets obviously when being in a dark room and ramping up the brightness (with adaptive brightness enabled) to 100 percent. now when i disable adaptive brightness, exactly nothing changes in terms of brightness, however former times, there would be still an increase in brightness since 100 percent with adaptive brightness does not equal 100 percent on manual brightness (at least in a dark place). now it does.
is this the same for you? was this an update or sth?
latest stock pie, with caesium kernel.
Something in kernel settings?

nothing set in settings.
also just tried another one, kikasura or how it is callled. same thing.
just that we are on the same page here: you still can increase the anchor value in brightness settings. or will it, too, just increase your overall brightness for a short time and as soon as lights change or you lock the screen it will be back to previous values?
I stop using auto brightness because some times he is crazy.
I prefer manual mod, like this I have the hand on it and i consum lot less battery (It's my feeling)
Adaptive Brightness is still working fine for me. The way I like to "calibrate" it is when in pitch dark, I set it all the way down to 0. From there it'll always go maximum when in sunlight and indoors it's somewhere in between and does fine. If that's not enough, try resetting adaptive brightness:

It is happening the same to me on very low light scenarios, auto brightness will go to the lower value, setting the screen without almost no bright, besides I put it manually higher. Maybe this happened after a update I dont know.

Screen too dim in low light areas

Hi,
I have the OnePlus 7T now since a week and I start irritating me on the low darkness of that otherwise nice screen. Outside everything is fine but in house and low light the auto brightness is too dim. Am I the only one?
I have the same issue. In the beginning I thought that the adaptive brightness will learn my manual adjustments, but after 3 weeks I feel that I need to start looking for an app to adjust the brightness correctly. Any suggestions?

I had the same problem.
I use Macrodroid to set the brightness to 40% at 4pm (adjust for where you are) and at 7am to switch to auto brightness. Seems to work well but I will look into using the light sensor to adjust brightness as this will work better throughout the year.
