does anyone know if its possible to adjust the back light dimmer lower than stock. I have tried the various programs that shade the LCD to make it seem dimmer, but they don't work the way I like. I want to use my xoom as a night clock, but unfortunately I can't get it dim enough. My Sony alarm clock has an LCD display that dims the back light in night mode to where you can barley see it. But in a dark room its perfect. All the other programs available just shade the LCD, but you can see the back light seep through and it keeps me awake. If anyone has a solution that can work on my xoom I would be grateful.
Thanks
Well nook app dims lower than normal while reading.

You could try the app Screen Filter from the market. It allows you to set a %.
I wrote an App that lets you control your phone's brightness provided it's running Android 8.0+ and has a compatible fingerprint sensor.
I wrote it because I change my phone's brightness as often as I change it's volume, if not more, and I was upset I didn't have dedicated hardware for it. When Oreo launched and it added fingerprint gesture detection, I figured it was time
I own and test on the OG Google Pixel, and the app has been out for 2 weeks so I've been able to squash most bugs.
Feedback and suggestions are most welcome!

Link doesn't work.
Dude... THANK YOU. Aside from ad-blocking and kernel tweaks, one of the main reasons I've always rooted was for the status bar brightness slider, and this is an even better implementation of it (I love hardware switches). The ads would never get in my way at all, but I went ad-free just out of appreciation.

For your device to be compatible, you have to be running Android Oreo and your OEM would need to support fingerprint gestures on a firmware level. I don't believe the One Plus 3T Oreo beta supports it at the moment.
The app is super cool; I love the option to adjust brightness via the fingerprint reader! One major complaint keeps me from using it though, which is that it always disables adaptive brightness when making an adjustment. This is extremely jarring when it's dark and I just want to dim the screen a bit, but bringing it down from 40% (adaptive) to 20-30% (absolute) actually makes the screen brighter. I hope for the next version you consider having the option to leave adaptive brightness on while making adjustments. Thanks!

Hi! I experimented with this previously, but since adaptive brightness is managed by the system, leaving it on when you adjust brightness will cause the brightness to be reset immediately by the adaptive brightness service. The compromise I added was allowing adaptive brightness to be restored as soon as the screen is turned off and on again.
@youtube10 thanks for this
when Oxygen OS will be on Oreo, do you think your tweak will works on OnePlus 5 ?
i change too, very often the brightness on my device...

Hi! I'm not sure. I'm going to set up a way for beta testing so people with phones not supported can check and verify if the app is compatible with their device. I should be getting around to that in the coming days. I'm just not sure if it should be through the Play Store or XDA. I don't think the Play Store allows for beta testing on specific devices.

Thanks for the reply. As another user mentioned, I'd be using your app primarily to replace the status bar quick finger slide feature from most custom ROMs, and those are generally able to work alongside auto brightness, which is why I assumed it would be possible. Personally I find this too frustrating to work around, but I appreciate that you considered this.

Out of curiosity, on those ROMs, how long did it take for adaptive brightness to restore the brightness to what it was before you adjusted it?
I don't think adaptive brightness and system brightness are 2 different values. It's possible you didn't give permissions to read or write to settings so that when you try reducing the brightness with adaptive brightness on, I can't read the current value of your brightness so I default to the highest. This would explain the "jump" in brightness you see while adjusting.
If you don't mind, try giving it another go and checking that you give both accessibility permissions, and permissions to write to settings. After that, with adaptive brightness on, try changing the brightness again and please let me now if the jump still occurs. Also, left and right swipes my default toggle minimum and maximum brightness respectively, so there might've been an accidental recognition of either gesture.
Absolutely love the app! Thank you so much.
Out of curiosity, why doesn't this app support previous Android versions? Asking for my own knowledge and would definitely love to use it on my spare devices running MM and Nougat.
I could see that certain fingerprint gesture apps like this do support the previous versions. Any specific difference?

It's because the gesture API was introduced in Android Oreo

I didn't view it as a bug in the app, just a side effect of disabling adaptive brightness. For example, the screen gets roughly to its dimmest with the brightness slider at around 20% and adaptive brightness on, so then if you slide that down to 10% but with adaptive brightness off, the screen will actually be brighter (the "jump" I described before). The issue is definitely not a result of a mis-swipe, as I can see the displayed percentage changing as expected.
I don't quite understand what you mean by "adaptive brightness to restore the brightness to what it was before you adjusted it"--my experience of sliding my finger along the status bar on my old phone to change brightness was the same as sliding the brightness slider in the quick settings, which can be done whether adaptive brightness is on or off. The adaptive brightness algorithm doesn't adjust the slider.
edit: I think I understand now; you're saying that the adaptive brightness algorithm actually changes the value displayed by the brightness slider. My Pixel 2 (as well as my previous phone, the HTC 10) both do not work this way, though I know some of the phones I have used in the past do. The Pixel's adaptive brightness adjusts the actual brightness based both on the ambient light and the slider, rather than adjusting the slider to what it considers an appropriate value.

You're right. They do seem like 2 different values. Especially that the lowest brightness setting with adaptive brightness turned on is lower than the lowest setting without adaptive brightness. I'll try getting it and the gestures to work together again.

You're absolutely right. They are 2 different brightness values: https://stackoverflow.com/questions/29349153/change-adaptive-brightness-level-programatically
It seems the Adaptive Brightness one is hidden and not supposed to be a public api, so I am hesitant to try to change it's value. However I can try to read it's value so that it would prevent the brightness jump if adaptive brightness is on and you're trying to adjust the brightness manually. Adjusting it manually will still cause adaptive brightness to be turned off however. It can be turned back on when the screen goes off and on and you checked the option.
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.
Have I missed something or does the adaptive brightness feature in the display options only work on the main display but not the cover display?
I know the cover display can be adjusted manually with a swipe down but if I've been indoors and have it low its then unreadable going outside and too dim to see the screen to turn up the brightness
Pretty sure adaptive brightness relies on the front camera sensors, which are looking into the bottom half of the screen when it's closed.
There is none, but I wish. Even just a manual setting based on time of day would be great.
To see it during the day it's just way to bright at night.
I have spoken to samsung support and it is the case that the brightness of the cover screen is manual adjustment only
