Night Light default - Samsung Galaxy Note 9 Questions & Answers

There's a yellow tint that automatically turns on at night. I have the blue light filter turned off, but it still turns on, has anyone else noticed this?

I haven't noticed that but it might be a safety feature they force implement? Don't know. That both good and bad though if it's forced on.

Turns out the stock android night light settings were carried over when I signed into my Google account. The setting is hidden on the Note, but still there.

Light flow... Does it work?

Anybody tried light flow yet?
Works like a sharm! No root necessary. The new notification light is much better then the speaker built in thing from the z1c.
Tested "Light Manager" and that works, too.
Can't seem to change the charging led though
Yup, I have the paid for version of Light Flow setup and working perfectly!

I just tested and i can't get light flow to change the charging LED. It doesn't even turn off if you disable the notification light in Androids DIsplay settings.

To bad. It's keeping me awake at night and really holding me from buying a dock.

I've been able to sort of fix this using Light Manager. I select a really dark color (almost black) for both charging and fully charged set it to be always on (no blinking).
It's kinda finicky, though, and sometimes it takes a few moments until it LM takes over from the built in notification light. For me, Light Manager works better than Light Flow. YMMV, it's possible to do this with both of them.

Just wanted to say that I have done this with Light Flow and it works great. It still shows the default charging colours when the screen is on, but when it's off it uses the ones in light flow. The trick is to use anything but totally black. I set it with the HEX code to FF000001 and it works.
That is on a full-size Z3 but I can't imagine the hardware is different regarding LEDs.
I use light manager and it does work with a dark colour to set the charging/charged led colour. (dark blue)
BUT
When I use sleep mode (so I get to notification lights) the charging/charged trick doesn't work ....
So I have to dissable sleep mode
anyone has a solution for this?
Lightflow doesn't seem to work for me neither.
Is there any other option without rooting the device (no option, as it's for the device of my girlfriend)
Works perfectly for me. Keep trying. Make sure it's enabled in settings security notification access.

Hmmmm very good point. Thx for the advice. I think I activated this after the installation of Light Flow. I remember some red info message bugging me But to be honest I can't find this setting anymore. Where can I reconfigure/ review this?

Ahh Thx But this doesn't seem to be the problem. Checkbox for Lightflow is checked there.
Will keep trying to get it working.
Thanks a lot for the help so far.
Light flow works like a charm for me and love how I set colour per notification type it's the only app that works 100%

LED Constantly On

I've got an issue with my camera flash LED. Sometimes after being in my pocket for a while, I'll notice heat or see the light shining through my pants, and find the LED is on. Not flashing, just constantly on.
The "flashlight" in the G4's settings is not toggled, and when I try to toggle it, it says that I can't use the flashlight while the LED is in use. I can't find any other running apps that would cause this or even use the LED, so I'm stumped, and my battery gets drained pretty quick!
Also, if anyone knows how to turn KnockOn off, I would love to know how. That could actually solve the LED issue too, if the screen is getting turned on and manipulated by my thigh while the phone is in my pocket.
Thanks!

I personally never experienced the LED turning on by itself. Also - Reading your comment, looks like you set the "knock code" and want to turn it off?

No, just the double-tap to wake. I think it's getting randomly activated in my pocket, and I don't use it much, so I'd rather disable it.

Vivid screen mode bug?

Is anyone having any trouble with setting screen mode to vivid?
When I switch to vivid, the entire screen becomes very orange, to a degree that something is clearly wrong. It looks like the blue light filter is turned on, even though it isn't. And turning on the blue light filter makes it much worse. It's like there is a single application of blue light filter permanently active, and then a full second layer being added when actually turning the blue light filter on.
This is coming from someone who generally runs Warm1 or Warm2 settings on my TVs and monitors. This isn't just a warm white, this is distinctly orange. Changing back to natural brings the white levels back to a normal level that I would say is pretty neutral, if not slightly warm.
When set to vivid, changing the white balance between warm and cool does almost nothing; the change is so subtle that you have to actually flip back and forth several times to notice it. And changing the RGB in advanced settings does absolutely nothing.
A couple other facts to note:
- I do not have any type of screen protector; the one that was on the phone out-of-the-box has been removed.
- This isn't just related to the angle at which I am viewing the phone; it is consistently orange from every possible angle.
- Blue light filter, night mode, and adaptive brightness are all turned off.
Is anyone else experiencing this, or is it just on my end? I have restarted the phone several times. I would really like to avoid a factory reset if possible.
i find mine to be more warm in natural mode however is been known that the screens on the S10 are much warmer than s9/n9 due to the reduction in blue light
if in vivid mode - please access the manual setup maybe the red is setup to max or something
Check that you do not have night light also selected in the drop down settings, as the s10 already has blue light filter reduction.
Mine was like that originally. Had to install Play Books and then turn off it's version of night mode. Seems that even though I didn't install it on this phone, it's night mode somehow still carried over.

As I said in my post, it doesn't matter what I set the RGB values to, they make no difference. And the whites look just fine in Natural mode, so it's not the screen, it's a software issue.

As I already said in my post, the blue light filter is turned off. It's off in the quick settings and off in the actual settings. I can turn it on and it doubles the problem; turning it back off returns to the normal problem.

I've never used Play Books before. Installed it just now and there's no night mode in it.
So it looks like the bug is tied to setting a schedule for the blue light filter. This morning the overly orange effect was gone. It seems likely that the setting somehow carried over from my previous phone and stayed separate from the one on this phone. Unfortunately, this probably means I will need to factory reset because there is no way of accessing this second schedule.
I won't be the only person that has carried over data from a previous phone and used a scheduled blue light filter. I hope Samsung fixes this in an update so that others don't have to deal with it.
In Play Books, open any free book and click on
then disable the schedule and hit turn it off now if it's on
Edit: screenshots aren't showing up for some reason. Anyway open any free book, tap in the middle of the page to bring up the menu bar at the top, tap on "Aa" and then night light settings. Set the schedule to "None" and hit end now if your screen is currently orange.
My wife has never installed Play Books, and that still fixed it for her.

Good to know, thanks. If the issue comes back again tonight, I will try this.
I think there is some hidden night mode in android which Play Books ties into. My wife's old Pixel had a night mode setting in the settings app which she had set up, and the new S10 night mode looks entirely different. Think copying settings and accounts over brought the hidden night mode settings over, and Play Books is just the easiest way to access that hidden setting.
The Play Books trick worked. Thanks guys!
Exactly like @lightmastertech said, the vanilla Android night mode settings are hidden but still active, and it carried over from my Pixel 3. Play Books allowed me to access this menu (odd that it's still there, 100% intact) and disable it.

Google's gonna get a lot of downloads for Play Books now, lol. Only app I could find that accessed the system night mode an not its own filter overlay. Glad it worked for you man! ?

I have a s10+ and just noticed I have the same exact issue. I posted earlier on the s10+ forums.. Natural looks much cooler
Nevermind.. the playbook trick worked. I came from a pixel and had the blue light setting turned on much earlier than my s10+. Thanks @lightmastertech @Sevael
Wow, just wow. Ran into this tonight for the first time because I wanted to try out the Vivid colour mode. What an amateur oversight by Samsung to not prevent the stock night mode from running. For those that want to have access to this setting without Play Books, you can use Quick Shortcut Maker and just search for Night Light, then launch the returned result. It will put you right into the stock Night Light mode.

Can you now change the color temperature after play book trick? I cannot still change it.
I just had to bump this because of the absolute cavalcade of potential issues that can cause the screen to appear tinted. I've googled this for almost a year now after only noticing the yellowing of my screen when in Google photos. Then the random tinting was happening at sunset and every forum pointed to blue light, vivid setting, night modes etc... To find this elusive setting in play books of all places, to fix an issue that's plagued me through my last 3 devices, to the note 10 I'm on now, and it's finally fixed. Thanks. Thanks a lot.
I have only just bought an S10, and I have the same issue as OP. I have installed play books and followed instructions on this thread, but can't find in on play books night light settings set the "schedule" to "none" and hit end now.
Thank you so much ! Same happened to my FOLD - You solved it for me !

Screen remains yellow after disabling blue light filter

I've had my Note 9 (SM-N960U) for a month, and I love it. However, one annoying issue keeps popping up. I have the blue light filter automatically enabled between sunset/sunrise. Sometimes the screen remains yellow/red after sunrise. When that happens, I manually toggle the blue filter, but the screen retains a yellow/red tint. I can reboot the phone, but it never recovers the stock blueish/white tint. The only solution that I have found is a factory reset, which returns the color temperature to normal. This has happened twice, and it is a major PITA restoring all of my apps and settings. FWIW, I am on the latest firmware and April security patch. Anyone else have this issue?

If you use the Google books app see if you have the night mode set on in that app. I was having this weird issue and I saw that I had set the tone to night mode for night time reading. That was causing my whole phone to become yellow instead of only doing it to the app.

CameraLightSensor

Anyone having CameraLightSensor battery drain?
Edit: it is 4g Exynos model, latest firmware
I just checked and I do not see it on mine at all. T-mobile version.
No battery drain on mine either.
Possibly disable the face unlock, its going to save alot of battery for you.

Don't have it enabled, it seems it is auto brightness
Off topic: could you tell me what kind of SoT you're getting? There are no replies yet in the official thread and I'm interested in the Exynos version.

Same thing on my T-Mobile model - 3.1% over 9 hours. I have not checked my unlocked model, as its still in the box.
Have you noticed the 'ring" of pixels around the camera changing color to black when using the phone? I notice it mostly when browsing the web, or on a phone call.
Hard to describe what it is, but a "ring" about 5 px wide turns black or dark grey around the front camera just for a second. Is that the light sensor thing?
---------- Post added at 12:37 PM ---------- Previous post was at 12:27 PM ----------
Interesting - I read an article about samsung using the camera instead of a sensor in new phones to detect the ambient brightness. The phone will take a picture, adjust the brightness, then the picture is permanently deleted. I guess that flash of the ring around the camera is the phone doing that to see what the light levels are in the room.
I turned off auto brightness and that ring flashing has stopped.

Definitely when you turn off auto brightness, the CameraLightSensor is not working in the background. But it must be a software glitch, it should be active only when the screen is on, it shouldn't be active while the device is in sleep.

I spoke too soon. Even with auto brightness turned off, the flashing ring of pixels around the camera still persist. ?
Edit: Sent in an error report along with two of them about the screen sensitivity issues.
Just checked my S20 FE 5G variant and it too has the CameraLightSensor draining at 2.8% for a total background usage of 8hrs and 28 minutes

Flashing ring of pixels around the camera???

Yes - Whether on the home screen, in a call, or in an app, there is a perfect "ring" (if you will) about 3-5 pixels wide around the camera that goes black for a split second or so and then changes back to the color of whatever it was displaying (think background color of a chrome tab, phone call, etc). It's impossible to catch as it happens so quickly. It's almost as if a perfect circle is turning off and then back on. And it has happened on both of my S20 FE, with or without adaptive brightness turned on.
I don't think it's something that screen recorder will even capture since that doesn't show the camera cutout, but I'll try!
EDIT: So I made a screen recording - and I think it was just the troubleshooting I needed to figure out what the problem is (was). . . When recording, the screen never shuts off, so there is no need for Smart Stay to activate (the camera checks to see if you're looking @ the phone to stay on). . . As soon as I stopped screen recording, that ring of pixels turned off and back on as it has been doing. I turned off Smart Stay, and it hasn't happened in the past 10 minutes or so. . .
I wonder if those that are seeing the high CameraLightSensor usage have Smart Stay turned on? It's not on by default - you have to look for it in settings.

I have smart stay off, accidentall touch protection off, face unlock off, and from today adaptive brightness off, and my CameraLightSensor is not working in the background when I turned it off. Auto brightness was definitely the culprit for me.
