Night Owl enable you to reduce the brightness of your device screen lower than you can achieve with the default settings in order to avoid eye strain or headache in a dark environment or at night. If you have an AMOLED display, you can also save battery!

Functions
• Screen Dimmer: Adjust the backlight brightness lower than default
• Automatic Stop: Stop the service at a specific time

I wanted a simple auto brightness app that scaled a wide range from full bright to very dim without having to manage very specific settings to get it to work properly. I created Lumen to do just that. I also wanted to create something that would get as bright as adaptive brightness does on full brightness but still dims to appropriate levels.
Lumen features:
* Custom color filter - includes ability to put filter on timers.
* One touch notification bar controls for brightness boost and color filter. Brightness boost also temporarily adjusts your screen timeout to 5 minutes. Once you turn off the boost or turn the screen off it reverts back to normal. Great for gaming or showing something to your friends.
*Automatically scales from night mode to full bright. Allows calibration slightly to easily accommodate different phones sensors.
Please let me know what you think, especially with the brightness levels that my algorithm puts out. Thanks!

For those who have tested it out, thank you!
Would there be any value in adding options to apply the color filter based on sunrise and sunset?

Hi,
I am using my Nexus 6p in a quite screen heavy way (mostly in the car) and I am looking forward to reduce battery usage.
What I am doing at the moment is:
1) Use AutoMate in the car for navigation and music
2) Set up the screen timoeut after 15sec.
3) Use Caffeine app to prevent screen from going sleep
As an effect of this after 15 seconds my screen dims to certain level and Caffeine keeps this state all the time.
The thing is that the dimmed screen level is too high for me and I am looking forward to reduce it.
I realised that if I change the screen brightness to minimum then "dimmed" level is also lower so I suppose the system is doing something "When dimmed lower the current brightness level by x%".
I do not want to change the "screen awake" brightness level but just make the system to dim my screen by greater percentage so then I could get to nice and bright screen with just one touch without having to activate variety of apps.
First, the use of system can automatically adjust the brightness adjustment system
We know that during the day and night, the brightness of the environment varies greatly at different times and locations. If the brightness of the LED display is greater than 60% of the ambient brightness, we obviously feel the discomfort of the eyes, which means that it causes light pollution to people. Through the outdoor brightness acquisition system, the ambient brightness is collected at any time. The display level control system automatically converts the broadcast brightness suitable for the environment by software by receiving system data.
Second, multi-level grayscale correction technology
The average display system uses an 8-bit color display level so that the colors are stiff at some low gray levels and excessive colors. It also causes the incompatibility of colored light. The new LED large-screen control system uses a 14-bit color display layer, which greatly improves the hardness of the color in excess. Make people feel soft when watching. Avoid people's discomfort with light
Third, the reasonable choice of installation location and reasonable planning of the display area
There is an empirical plan for viewing distance and viewing angle and display area, while image research has specific design requirements for viewing distance and viewing angle of the display screen. When designing the display screen, it should meet the design requirements as much as possible and plan properly.
Fourth, the selection and design of the content
The LED large screen is a public media, with public welfare, advertising, and instructional categories. When we choose to play the content, we must agree with the public request to avoid refusal. This is also an important aspect of preventing display light pollution.
The LED diode itself is a green light source. Although it is caused by a design consideration and application requirements on the large-scale LED display screen of the cluster type, this kind of contradiction is inevitable, and It cannot be completely eradicated. Only by using technical means and policies and regulations to minimize the pollution of color light, coordinate the needs of advertisers and the public's viewing psychology. At the same time, we also see that compared to today's neon and white light box advertising, the light pollution of LED display has been greatly reduced. And LED electronic display also has the advantages of energy saving and rich color, it will be a comprehensive alternative to neon outdoor lighting, information display.
Just curious. How many of you are seeing screen-burn in on your phones?
I use CF.Lumen to adjust the screen to be warmer at night. I notice some darker areas/burn-in with CF.Lumen enabled and the screen brightness dimmed to super low levels (using CF.Lumen's built-in darkness slider for Sleep mode)
What I notice is a sort of dark spot at very low brightness, and a sort of dark shadowy line running down the screen close to the left side. It's kinda annoying but I really only see it when I have text on the screen (and I'm trying to read text) at lower-than-stock dimness levels. I'm slowly getting used to it. At first I panicked thinking that my screen had burned in already at a few months of use, but when I have CF.Lumen off and I have the stock brightness slider set all the way to 0, I don't notice any lines or weird dark spots.
Then again, 0 brightness using the stock brightness slider is still VERY bright if you're coming from iOS's Accessibility settings. Android has poor screen filter settings and few good screen filter apps outside CF.Lumen and f.lux and I doubt Android 12 will change that.
So, are any of you experiencing screen burn-in? OLED burn-in is something that always has me worried. I try to avoid OLED phones for this reason, because I'm paranoid.
OLEDs have a finite lifespan. The brighter they burn, the shorter they last.
The higher energy blue emitters have the shortest life span, while red the longest.
Darker screen wallpaper, dark mode and less white icons/headers helps reduce wear.
Use manual brightness control and avoid going over 50% whenever possible. Don't use in direct sunlight... this is a killer.
Move icons and widgets periodically on the homescreen. Avoid prolonged white screen viewing and apps that are dark mode illiterate.
These practices also increase battery life substantially.
Use Screen Test to see if any damage is present.
After over 1.5 years of heavy usage and one battery replacement, my AMOLED display on my Note 10+ shows no signs of damage. How you use it day to day/what you view with it makes a big difference in display longevity.
