Hi
So let's take a break from pursuing after Lollipop and improve what we have
Well, many of us know that a report came out suggesting that 'blue light' emitting from screens of mobile phones, TVs, PCs etc is harmful to the eye and causes sleeping problems.
And then many apps started coming out which remove/filter the blue light from phone screens, such as Bluelight Filter, Dark Screen, Twilight etc.
These apps do what they say but :-
1) They don't do it perfectly
2) You have to manually disable them each time you install something or grant superuser access to an app
3) Few of them consume fair amount of battery
4) And some people may be annoyed by the fact that it always stays on the notification bar.
So here's another the way of removing the blue light without causing any of the above mentioned problems
The way is to change the kernel settings, rather the screen color settings by using kernel tweaking apps like Faux123, Trickster Mod etc which almost every custom kernel user has.
So open your kernel tweaking app and go to' Screen' settings or 'Screen Color' settings or whatever is there and just reduce the quantity of the blue color according to your preference
I have attached a screenshot of blue light being reduced using Trickster Mod app.
Don't forget to hit thanks if this helps
Thanks for the tip,
I've seen someone using bluelight filter app with his z3 compact, i couldn't figure why. Now i know. The screen of his phone looked pinky though.

Which version of trickster mod did you use, i do not see anything related to screen settings in the version i have
Does anyone know a clever way to detect the active display in tasker? Currently I use luxauto brightness to keep the OLED display dim in the house, but the same filtering it does to get below 0 brightness also grays out the eink side, particularly when I have it face down on a desk. It's easy to detect and act on that state with the proximity sensor, but it would be nice if there were a way to trigger based on active display so that I can disable lux in low brightness situations where it isn't face down and I am using hte eink screen.
I was able to figure things our digging through the source code Jeopardy posted, sorry for not digging around more before posting. If anyone else wants to replicate here are the basics, I can provide more detail or screenshots if needed. I disable lux in tasker with a profile that looks for event intent received "yotaphone.intent.action.MIRRORING_START". I have a task that reenables lux whenever the intent yotaphone.intent.action.MIRRORING_STOP_MANUAL or yotaphone.intent.action.MIRRORING_STOP are received (2 profiles, each trigger the same task).

It's great to see you found use for my findings. Just out of curiosity, is there a specific reason you could not just use android's automatic brightness? I think you could even modify the threshold levels for it with some xposed module.

Lux seems to do things much cleaner, allows sub-zero brightness, and is more customizable as far as number of points and smoothness of transitions. I noticed that gravity box might have had a way to do things like this after I installed lux.
I don't know if it's just me, but I was previously using the app midnight to dim my phone at night & had no issues.
It appears with Oreo, that the status bar & when you pull down the status bar don't change with the screen.
So while the screen is only set to say 30%, the status bar & nav bar are full brightness. Again, I don't recall this issue
with 7.1.2
Is anyone successfully using an app that actually dims everything with Oreo, & if not, is this an issue with Oreo?
Thanks!
I am having this issue with my device and it's driving me crazy. I did not have the issue with Nougat, but in Oreo none of the apps work on the status bar and notification shade. This is exacerbated by the fact that the notification shade is blinding white now instead of dark gray so it lights up the room when I pull it down at night in the dark.
I normally use the app "Darker Pro," but I tried about five different screen dimming apps last night and they all have the exact same issue so I think it's an Oreo thing. I also used to use the app Snap Swipe Drawer and noticed that I can no longer activate it from swiping on the notification bar. I think Oreo is not allowing anything to draw over the status bar or notification shade area.

Exactly! The notification bar is extremely white which just furthers the issue. The white was a poor choice in my opinion and is hideous.
I've tried 2 other apps & no luck. Plus many don't get updated.
I emailed the developer of Midnight & he said it would be a priority, so that's good.
I'm glad someone else uses these apps. I was beginning to think everyone enjoyed being blinded by their phone at night.

I don't understand the issue... Just dim your display normally using the brightness slider. Everything gets dim that way.
If you want a working night mode too (blue light filter), flash the o pixel mod in the themes section and use that too.
Or even f.lux would work if you have root.
This is a complete non-issue because dimming the display works 100% without any 3rd party apps.

The issue isn't the fact you can't dim the display as we all know you can move the slider.
It's night mode apps only dimming the screen itself & not the notification bar. You may have your brightness in night mode to really dark, but pull down the status bar & it's 100% bright. This issue didn't exist on 7.1.2 with these apps. I was specifically using Midnight with 0 issues.
I'm not rooted, so no flashing. Also there was no need before O as these issues didn't exist.

Well it sounds like the app needs to be updated to work on Oreo properly.
One of the reasons there are dev preview is for developers to test their apps on the new Android update and it would seem that this dev didn't do that.
Can I ask why you don't just use the brightness slider? It's one of the simplest things to do if you want your screen dim.

Because it isn't dark enough at night and early in the morning when I like my eyes to adjust. If it went darker as part of stock Android, it would eliminate the need for these apps.
Personal preference. My wife can't see crap & has to have the brightness on her phone up even at night. Drives me nuts & blinds the crap out of me.

Okay gotcha, makes sense.
Hopefully they update that app soon then.
If I come across any other app similar to that, I'll mention it in this thread then
I've been using f.lux and that seems to be working OK with Oreo.
I used Twilight Pro when I was on DP4 and while it worked, it did have the persistent blinding overlay notification. You can manually mute that for 2 hours tops at a time or there is a way to keep it muted with Tasker. https://www.xda-developers.com/hide-app-running-background-notification-android-oreo/
Does your app provide administration rights capability? There would be an entry in device administrators for your app [name]. For example, I use Bluelight Filter and if I want to use full dimming capability, including overlay, I have to give admin permission. The trade off being that some Android security lock features are disabled - such as locking Android pre-boot with a password.
It's been posted in another topic, but as far as "muting" the messages about background notifications in Oreo, this is a new Android security feature with no workaround yet and you can only set it to a low priority for notifications. At least that way it will minimize to one line when there are other app notifications, and remove the icon from the status bar.

Where are you finding device admin for bluelight? I had it installed, didn't work, but reinstalled trying to find what you stated, but no luck.
I've got a device admin apps settings, but it isn't listed.

Sorry it's not device admin, it's accessibility. My bad. This is the permission that's required for notifications and screen overlay being dimmed. It's a trade-off. So far I don't use it because I prefer enhanced encryption.
What I loved about my screen dimming app is that it did so automatically at set times and precisely to the right level. The brightness is now at daytime strength the first time I turn it on at bedtime and too dark when i first need it in the morning, not to mention fiddling with the slider to get it just right. Is there another way to schedule the brightness levels?
Still no one with luck with this?
Once it's a cross-device problem, why not move the thread to a general forum?

Did you find a fix for your problem?
Personally I am rooted ONLY for the night mode included on the pixel 2 mod. Furthermore, I was looking for a way to only have the night mode w/o any other pixel feature but couldn't find a way.
I know you said you aren't rooted and I can guess your unwillingness to do so, but honestly that's the best way to get a properly working night mode.
Take into acct. that I've tried a lot of apps and none were satisfactory. As I said before, this is the only reason I'm rooted.
Anyways, I hope you found a way to get a night mode working on your phone.
Any success? Really would like 100% overlay coverage including notifications, everything.
If you web browse at night you can invert the screen colours, which helps a bit until you hit a 'dark' image
I use Darker Pro and yes I can confirm that the status bar and notifications/qs panel does not get darker on oreo.
I used the same app all the time with nougat and it worked flawless.
It is a android oreo issue. Google has disabled apps to draw over system ui elements in oreo, that's what the darker pro playstore description says. I initially thought we need root to enable it. I've been trying to search for root apps that would let me do it but no luck there either.
Alright. I got a bit of a Work around. You will need root. Install Kernel Adiutor and go to Screen option. Now lower the Red, Green and Blue values equally. The screen will get dimmer.
I know this isn't as convenient as using a simple app, but atleast it's something.
Oh, and if you're running a lineage OS based rom you won't need root or the kernel Adiutor. Just go to Live Display in setting and you'll find the same Red, Green and Blue adjustment there.
This one works over both bars, but needs xposed:

Whenever I open the stock camera app, screen brightness is automatically set to maximum. I get that it's a feature some people like to take better photos but there should be an option to disable it. Other camera apps have this option but lack EIS or portrait mode. Would really like to use the stock app but this one issue is very annoying. Any help?
To enable EIS , click the given link
https://www.xda-developers.com/enable-eis-asus-zenfone-max-pro-m1-without-root/
If you feel that the camera is really important then you can explore XDA for enabling google camera on phone .
The automatic is a default configuration in the phone and you cant do anything for that . Its actually useful because sometimes the display is visible during bright sunlight . Or else install the Nokia camera port on the phone. It will also give the extra PiP feature :laugh:
