Stock blue light filter color - Samsung Galaxy Note 9 Questions & Answers

Is there a way to decrease the color temperature using samsung's stock blue light filter?
I tried using twilight but it's an overlay and very inconsistent.
I wish I could make the color warmer.

yes you can, drop down quick panel, then keep pressing blue light icon, it will take you settings to adjust it intensity, schedule time on/off.

Thank you for your answer.
And I should have described it better.
I mean even warmer than that. I already have it in the highest color temperature value in the settings.
But still I find it quite not warm when lowering the brightness.
Anyways thanks for the input.

[Q] lower brightness

Hello,
are there any solution on lower brightness in jp6 like voodoo 4 on 2.1?
The screen is too much bright at night!
Anybody knows this comes with one of the next releases of voodoo5?

Im using extended widgets too, mine goes as low as 1% but i think thats still the systems native low brightness Voodoo goes even lower...
Just slide your finger along the notification bar.
app called "brightness level"
set to 0%
Interested in this as well.
I think we are actually looking for something lower than 0%
It is probably the amoled screen vs backlit one, the way they operate. 20% on lcd is much lower than 0% on amoled.
Maybe there is some kind of overlay that can act as Rayban? Like ie when you do Titanium backup, you can see the rest of the application being much darker than the notification that pops up. Probably some overlay being used.
Maybe some of you asking yourself why, but try using it in complete darkness for awhile and you'll see what I mean.

Thats what i mean like a torch in the night.
I had tested all brightness apps in market but no one goes lower.
Thanks for help.
Mybe a dev or supercurio can help to explain
Yes, the lowest stock level is already quite bright, too bright of course for night use in bed.
You'll also notice that the colors & contrast looks quite dull on the lowest stock brightness settings, with a color deviation in the red shadow colors.
With the revamped Voodoo color which will be released step by step during the next weeks, you'll be able to go so "dark" (if chosen) that you'll be almost not able to see it in the dark even when on
All that, preserving color accuracy and color temperature (which goes more red when you lower the brightness on stock)

Dimmer shows it goes from 30 (lowest stock) to 10...

[Q] Auto brightness doesn't work

Hi
The "Adapt to lighting conditions" is checked, but it doesn't really adapt. I have to manually change the slider to adjust brightness.
Looks like a bug. Not sure if there are any other settings to make.
Is this a known issue? Any workarounds?
Thanks.
Farhad.
The slider sets the maximum brightness of the screen, not the minimum. Hence, in order for the auto adjust to work, set it to the max and tick the check-box.

seems to work more like a brightness scale kind of thing. not only sets max, but minimum as well.
it'll always adjust when the box is ticked, but the slider determines how bright or dark biased it is.
It's a sliding window of brightness ranges, which should be good news to anyone who's felt that autobrightness on other phones swings too far in either direction. Now you can customize to your own taste.
Personally the sweet spot for me with good compromise between use in low light indoors, daylight and office lights is about 25% - the slider button just above the second "g" in "lighting conditions"
Remember though that changing White Balance settings will darken the display, and you'll need to boost brightness to get decent contrast again.
Use Lux Lite from the playstore. It lets you individually "link" a specific brightness level to a specific lighting condition, which the app then remembers and automates.

What do you mean "Source"?
That's how it work[s|ed] on my Xperia U, Xperia M, Xperia SP and now on Xperia Z3C.
Not proof enough?
It works, but doesn't work well. When I wake up at night the brightness level goes lower but not nearly low enough. I have to manually reduce the brightness to the lowest level. When the day starts, I have to manually increase the brightness. Not ideal, not a deal breaker either. Hopefully Sony addresses in the next update.

App that uses brightness toggles?

Hi,
Not sure where the correct place is for this, so thought that I'd put it here.
I am looking for an app that controls brightness. I like the brightness of my phones to be dialed down to around 40%. I find it most comfortable for my eyes. Yet when it is bright out, I need to make the screen brighter. This means that I need to go in and manually adjust the brightness. I don't like to have the phone set to automatically adjust the brightness.
I'd like to find an app that allows adjusting brightness by icon. I don't want one that has one icon that toggles through a bunch of preset brightness levels. Instead, I want an app that can have different icons for different brightness levels. That way, if I wanted to toggle the brightness to 60%, I could tap an icon that does that. Then I could have an icon set for 30% to set it back.
Anyone know of an app that does this?

Lux, if properly configured, could do that for you.
I think I understand what you're going for. I use Power Toggles (Dev: Painless Apps), and one of the toggles on the widget is for brightness and I have it set to 3 settings when I touch it; 20%, 40% and 100%. It's not possible to set each new brightness widget for individual brightness presets, unfortunately, but I don't see how it would be difficult to just make some predetermined settings for your brightness.
By now you should have a pretty firm idea on what level of brightness you prefer throughout your day so maybe you can use this app and have 2, 3 or more presets. It's really simple to use, I have it set to 3 settings and touching the widget to get to the brightness I want at that moment is super quick and not difficult at all.
You can see in the screenshot I use the widget at the top on my home page. Brightness is among the other toggles I use on a regular basis. Much quicker to turn on and off things, IMO. It's right there on my home screen so I don't have to pull my notification window down. I hope this helps.
I just use Auto Brightness setting. I set the brightness slider at 40% and the phone will auto-adjust the screen to keep it at a relative 40 indoors and outdoors.
I think this is what you're looking for:

[APP]OLED Saver (flicker free backlight dimming, no PWM)

This app is a life saver for anyone who suffers from "invisible" screen flickering caused by PWM backlight control. Most AMOLED displays control lower than 100% display brightness by PWM. This method is extremely easy to implement, but can cause eye strain and headaches for sensitive people. DC dimming is rare as it is hard to implement without sacrificing color accuracy. This is where OLED Saver comes in handy.
How to use:
- turn off system adaptive brightness
- install the app, allow permissions it requests and enable the service
- set minimum screen brightness to 255 if you want to have the safest value (guaranteed to have zero flickering). After further testing, values as low as 96 seems to be still safe - but test it with your phone to be sure.
- minimise the ongoing notification to hide it from lockscreen
- turn on automatic brightness change from the notification ("A")
- remove OLED Saver from battery optimizations
In some rare cases you will need to suspend the service from notification (while taking screenshots for example, app installer might need it disabled too).
If you have Tasker and root access, you can toggle the service to force 100% brightness automatically. I'm using 100% while viewing videos/pictures and taking photos.
Start service
Code:
am startservice org.js.oledsaver/.MainService
Stop service (this will remove also notification)
Code:
am stopservice org.js.oledsaver/.MainService
So far I haven't found any negative point while using this app, just wish it was included in the AOSP code so we could still use adaptive brightness. Anyway, give it a try and share your experience.
I used to have some trouble watching text on this display under certain light conditions.
I don't know if it is just a placebo effect, but since I've installed this app, I don't feel any discomfort anymore.
I also can't see any difference in picture quality.

You can easily check if it's working with another phone's camera. People have different sensitivity to PWM flickering, from none to watering eyes. You are probably somewhere in between. Without the app, I had a slight feeling like something was pulling my eyes. As soon as I enabled the app, this sensation has been gone. My wife doesn't see/feel any difference, but I left it enabled for her anyway, just to be on the safe side.
Thanks a lot for introducing this app. It works.
However I encountered a problem. With this OLED Saver activated and using GCAM to take photos, it boosts the brightness to maximum. Then I went elsewhere like home screen or other app, the auto brightness seemed not working and kept the max. brightness.
Then I tried locking the screen and unlocking, the brightness went up or down randomly, or it worked in some particular patterns I don't know. Anyway, it can't keep the brightness I set previously.
Does anyone has any idea to remedy this? Thanks a lot.

Which GCAM app do you use? I'll try it. In stock camera it doesn't behave this way.
Btw. I tried to contact the developer if he could add global intents so we could control OLED Saver with Tasker and without root, this should help in preventing this kind of behavior. No response so far though. If you are rooted you could use method mentioned in the first post.
Also I'm in touch with Velis Auto Brightness developer - this app offers much more features (customizable automatic brightness levels, apps exclusion and more) and has similar feature for OLED displays, but sadly it doesn't work on status/nav bar as of now. If he manages to use the same method as OLED Saver, we could switch to VAB app.
The GCAM version is 7.0.009.259843690.
Phone model is M1906F9SH (64G global version) with OE ROM.
Thank you.

Hm, I can't replicate this. I've installed GCAM, enabled max brightness for pictures (but it does nothing, as system brightness is at max already and real dimming is done with OLED Saver, which is not being controlled by GCAM). Moving to/from GCAM doesn't change anything. If I manually suspend OLED Saver from notification, GCAM shows max brightness correctly. On resume it returns to the expected behavior and dimmer display.
Yeah, sometimes I got what you described. Sometimes it rushes to very very bright, but sometimes it can be very dim...
I'll try reset it again and see how it goes. Thanks for your time.

I think that I saw OLED Saver "crash" once while using the phone - brightness suddenly went to max and was controlled by system. Since I removed this app from battery optimizations, it seems to be stable. Though this does not explain rapid bright/dim changes.
This looks very useful but what is it doing exactly? Is it running the screen at max brightness at all time and using some kind of overlay to dim the screen? Isn't that bad for battery life?

Yes, as you said, running HW brightness at max and putting a translucent overlay over the screen. It's basically SW implementation of DC dimming. It has a small artifacts with very low brightness, especially on grey colors, but otherwise no issues. Impact on battery should be negligible (OLED displays work different than LCD).

Hi _mysiak_,
I changed to some other version of GCAM (without the max brightness view finder) and then this OLED Saver App is working fine afterwards. Thank you.
Then I found, when in very dim setting, occasionally, the white color (now it's actually gray) seems not stable. It could be fluctuating from neutral gray to warmer. Not intrusive, though. Do you see that?

Yes, I noticed that "slow flickering/artifacts" as well. I believe it's the side effect of DC dimming method and probably one of the reasons why it's not so widely used. From what I read, Samsung AMOLED panels are designed to be used with PWM dimming, so we probably can't avoid it with very low brightness. If it's too disturbing, I just move the OLED Saver brightness slider a bit higher (it stops completely at roughly 40% brightness). Using pitch black themes in apps helps too. Not a perfect solution but definitely better than PWM
Btw. it's the same for any app using translucent overlays, I tried a couple of them and at similar brightness, all behave the same.

It seems to be at 80% and below. 81-82% and above should be safe.

Try to change the "basic physical brightness" to value 96, artifacts don't disappear completely, but I don't notice them so often.
Level 96 in OLED Saver corresponds to HW brightness level 82%, which seems to be still free of PWM.
Thanks for the tip.
It's really works. Thanks for the tip ???

Too bright colours

Is there a way to avoid that under bright light the colors are too bright and washed out?
The pixel 2 xl has more saturated colors under bright light.
Thanks.

Yes it should be. What is confusing to me you said boosted and washed out in the same line.
How can saturated colours be washed out?
Have you tried the adaptive profiles?
Ok sorry, I try to better explain...
I'm on natural + ambient EQ
When I turn on the screen, if there's enough light (so almost always during the day) the colors look very bright then slowly slowly they go back to sort of normal.
I notice this because I have the calendar widget and lots of yellow events: when I turn the screen on the yellow looks very bright.
