Display gets almost always brighter and darker when I watch videos, use apps etc . Auto brightness are disabled. How can I fix it?

how it was before it happened: my phone was perfect.
how it happened: i had a custom kernel, and when attempting to reduce gpu voltage (without having set on boot set) my phone reset.
symptoms: it's like dynamic brightness in reverse. This is what dynamic brightness is on our phones: Galaxy Nexus Dynamic Screen Brightness - YouTube This is NOT auto-brightness. It's like dynamic contrast on a TV. It's supposed to be that: When the screen becomes dim, the brightness increases. Note in that video the bright horizontal line at the top that appears when the screen gets darker and dynamic brigthness kicks in.
when my screen gets dim, the brightness drastically decreases (looks normal). open it to an all white screen, or turn up the brightness, and the screen brightness increases. i get that bright horizontal line at the top on bright screens, instead of dim screens. the whole screen gets that purple tint and vertical banding that some have complained about.
this effect happens even when the phone is off, and the battery charging icon is showing. once enough white is shown in the icon, the brightness dynamically increases. happens on boot screens (normal during dark boot screens, drastically bright on bright boot screens), and on recovery and bootloader screens. totally brightness dependent change in brightness.
this makes me think that it is something messed up in the very low level of the code, not the ice cream sandwitch part, but something like the display driver of the gnex.
what i've tried to do to fix it: everything, including flashing stock factory image and relocking my bootloader.
result: nil
please help if you have any ideas. Thank you!
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.
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.
Anyone else have issues with the screen where certain colors just disappear at lower brightness? Red's just disappear on my screen and so do grays. Here's a video of me adjusting the brightness and you can see the red and gray just disappear and comeback as I adjust the brightness.

Brightness should stay at zero% and I'm using the strength at 70%
I'm getting to the point where I want to get rid of my pixel 2. Sick of black crushing. Videos at night or in dark rooms look garbage. Even taking photos at night I can see the sky or blacks pulsing in a blotchy mess. Looks like Google is going to sweep this under the rug.
Tried all types of settings and the app and I still see it.
If I keep the brightness to the Maximum, I notice that in bright sunlight/extremely bright indoors, the screen gets Automatically even brighter and dims when the phone notices the environment is not that bright !!!!
You can experiment by shinning a flash on the top right side of the phone with slider on max brightness.
Isnt it stupid – When the user have disabled auto brightness or any power saving modes the phone keeps getting bright and dark
I cant believe Samsung has let it pass this to the production models…
bump - anybody ?
