Night mode isn't as dark - Samsung Galaxy Note 10+ Guides, News, & Discussion

Lying in bed last night I turned on Night Mode. I noticed when I pulled down the notification shade, the top portion was still dimly back lit, so I could see the camera cutout and the edges of the screen, no matter how much I dim the backlight.
Well tonight I fired up my Note 9, put it on Night Mode and pulled down the notification shade, and no matter how bright or dim I have the screen, the top part is BLACK. no light. You can't see where the screen ends and the frame begins.
This isn't a huge deal except for battery savings. When an AMOLED screen is true black, those prices shut off. But since the night mode on the N10+ isn't true black those pixels are still lit up and using power.
When viewing video in Netflix or YouTube the black bars are truly black, so I know the screen is capable showing true blacks, I'm just not sure why Sammy changed Night mode so it's no longer truly black.

I have just experienced the same thing. I have a note 9 as well to compare. I'm actually deeply disappointed. I also noticed screen mode only has 2 options... vivid and natural. Where as note 9 has 4 screen modes. I'm trying to figure things out to see if I can get it to be true black.

It's probably normal since it's a night mode and not a black mode ; in which you wouldn't it to make your screen showing heavy contrasted differences that actually made more eye fatigue than the light one.
Maybe I'll finally like this mode on this new phone.

No I understand it's a "Night mode" but I'm comparing it to the Note 9 and Note 8 Night mode where it became a true black. And I ran it in Night mode almost 24/7 for some battery savings as well. Well that doesn't work if Night Mode is just a dark grey rather than a true black.
And I'm not sure how true black and contrast made for more eye fatigue? Have you never watched a 4K movie? The whole point of high def is high contrast with true deep blacks, bright whites, and bright colors.
I also noticed on the quick access home screen in Samsung Browser on dark mode, it's not longer a true black. Now if you turn on High Contrast mode in the browser settings, then the background is a true black, so that panel is capable of turning off the pixels and going true black. This means it was an obvious design choice.

Dark VS black doesn't make much difference battery wise on OLED screens (let me just find the test back and I'll update my post)
Because the notification panel and anywhere else that it matters contains mostly texts and it produce visual retina persistence (not sure if I translated well), plus it's more annoying to read and and eyes accommodate less than in light mode where everything is light too.
There's nothing to do with movies since it's dynamic and constantly changing from a lot of different colours while texts are more static (but going from dark to light scene still hurts)
I agree that it's absolutely a design choice, but in my opinion for the better.

I gotcha. Makes sense. I'd like to see some tests on black vs dark. I had always heard and though the battery savings was due to the pixels shutting off. It's why the AOD is black and not just dark.
Buts also weird. I'm replying to this direct from the Gmail notification of your reply. So it opened up the webpage in the webview. Well the top bar above the page that says reply to topic and has had the Gmail overflow button is true black. But the status bar right above it is dark grey.
I guess what bugs me most is it makes the camera cutout stick out, even in the dark. Because I look up an I see a true black for on a dark charcoal background. And I can see the screen edges. I preferred on the Note 9 where it all just blended away with the true black.
But yet, when I watch a movie, the status bar DOES turn off completely and you can't see the camera cutout. Just can't figure out the inconsistency.

It may be because apps got their own night mode colour settings embedded, while all One UI apps got theirs which are different.
Like, if for Google night mode is all black, their apps will just check about system UI night mode trigger and of its on, apply their own settings.
I can only find that reason for it to be such inconsistent.

I totally understand and agree ! Especially when you like what Samsung did with their UI
In an other hand, there's some third party theme that may be of use to have a black theme : https://forum.xda-developers.com/s10-plus/themes/theme-anxious-t3921645
I don't know if it's working for the Note 10 yet but I think it's just a matter of time before it do

I just use a theme that's mostly black everywhere. No need for night mode..

One UI notification shade isn't actually black for any of the devices on the One UI. I had an S8+ before this and it looked black but if you take a screenshot and measure the color value, you'll see that it's not black. You can do the same thing on your Note 9. Take a screenshot and extract the color value. Or take a screenshot and then transfer that screenshot to the Note 10 and view it on the Note 10. I guarantee that the Note 9 screenshot of the notification shade will look like the Note 10 notification shade. Black will cause AMOLED smearing which isn't good look.

So I tried this. Set my Note 9 to Night Mode and took a screen shot. Sent it to my N10+. Guess what? The notification shade in my Note 9 screen shot is pure black when viewed on my N10+ screen.
So I did the opposite. Took a screen shot of N10+ notification shade and sent it to my Note 9, and it appears dark grey.
So I'm not saying you're WRONG, but this is proof that the notification shade on Night Mode on the Note 9 (and the Note 8) was SIGNIFICANTLY darker than the N10+. If they aren't true black, then they are so close at to be indistinguishable from it, whereas the N10+ is definitely lighter than black.
I also just used an app to do a color value sample on my screenshots. Note 9 notification shade is #00000. I believe that is true black?
See my attached screenshots. War Machine is Note 9 (The one with the true black notification shade) and the Darth Vader is the Note 10+ (the one with the dark grey notification shade)
To see what I'm talking about, you may need to turn brightness up on your phone or go in a dark room.

Screenshots of color picker showing Note 9 notification shade is #00000 (true black) and Note 10+ is #080808 (not true black).

I tried this. The notification shade was still dark grey, not black.

Samsung doesn't use black on the N10, it's that simple. They use a form of grey that's fairly close to pure black, however. The avg person probably uses white themes, so I doubt many will take notice.

Write back when you find a solution to make samsung browser black.cheers.

As Nastrahl pointed out it the pixels don't need to be completely off to save a lot of power. I was going for total black but since I adjust brightness manually a little bit of tint to the black looks nicer and makes it easier to gauge the brightness.
You can use the Good lock app Quickstar to make the pull down notification panel any color or darkness level you want. Mine is almost black with a hint of forest green.
My wallpaper is even darker with the same green tint.
When the brightness is too high the wallpaper's green tint is noticeable otherwise it looks black.

Better control over brightness

For amateur astronomy use, I needed to be able to bring down my A43's LCD brightness to a very low level. After a bit of experimenting, here is a very simple app that lets you have a darker screen than the OS normally allows:
http://code.google.com/p/superdim
It requires root.
This is my first independent Android app, so no doubt I screwed up in some way.

Nice, if you need it, make it. Personally, I find using Night Mode in Chainfire better than simply turning down brightness. It turns the brightness down, and renders everything in red, or whatever color you choose, but red is the correct choice to retain night sensitivity.
Obviously, I probably wouldn't watch a movie like that, but it's great for when I'm bow-fishing by full moon and want to change songs or something without wrecking my night vision.
For astronomy purposes, ChainFire3D's night mode won't be enough. At the lowest normal system backlight setting, if one is fully dark adapted under a dark sky, the amount of light leaking through the black pixels will be enormous--the screen will look grey rather than black (well, I haven't tried it, but I have experience with other devices). What one needs to do for serious night vision protection is to BOTH turn the view to red with ChainFire3D AND dim the backlight to a very low level with this app. And I am not even sure this will be fully satisfactory, because on my A43 the amount of light leakage is really big.
By the way, I posted a new version and source, and renamed the project to SuperDim. I also added a toggle for the power LED, since they made it green rather than red.

Hmm. That's good to know for the A43. I'd like to know what you think of the night mode in chainfire, just because there aren't many other people who worry about this topic. I live in St. Louis, a big city, so you probably have less ambient light, but I also wonder if my A101 gets darker than the A43. Even at night, I can turn it down to the point that I really can't read a damn thing.
Great idea with the Power LED. Once again, I don't think light levels drop low enough in St. Louis for it to bother me, but I hadn't even thought of disabling it.
To really be dark adapted, you need to be away from white light for about 45 minutes. (Though I find that after 15 minutes the payoff diminishes.) It's not going to happen outdoors in a big city.
I added profiles (three night, two day), and integrated SuperDim with ChainFire3D, so if you have ChainFire3D installed, you can control its night mode directly from SuperDim, and even include its night mode setting in a profile.
For my own use, I wanted a red screen dim profile for astronomy, a green screen dim profile for reading books in the dark, a dim full color profile for other night use, a bright green profile sometimes for reading books in the day, and a full color bright profile. But you can save whatever you want in the five profile slots.
I've been using figuring out the light control stuff for SuperDim as an opportunity for learning how to program for Android in preparation for writing (not from scratch--I got a donation of the AstroTools source code under the GPL to start with, and I may port some code from open2sky and AstroInfo for PalmOS) a high-end astronomy app. (I'm an experienced PalmOS developer, but quite new to Android.) I'm actually quite pleased. I was dreading java (I've usually developed in C), but I am finding Android development, especially with Eclipse, surprisingly pleasant.

Yeah, my point exactly. I'm about 15 miles away from the city when out on the river, but that's not really far enough to get out of the city's light pollution.
Great work integrating with Chainfire. I'll give it a try next time I'm out. It should be nice having everything in one place.
I'll be looking forward to the astronomy app. It's been a looong time since I've worked on one, but I still have the DOS version of CyberSky I helped develop, so I guess I still have a fondness for them.
I posted 0.23, fixing a bug that made day2 = day1.
And I posted 0.30, adding support for toggling keyboard and button backlight on devices that have them.
I use screen filter to make my screen dimmer..
its in the market..
1. As far as I can tell, Screen Filter doesn't adjust the backlight--it only lowers the LCD pixel intensity. As a result, even if you turn Screen Filter to something really low like 2%, if you take your device to a dark area, you'll see a grey glow coming from the screen, because the backlight leaks through the black pixels.
To remedy the grey glow issue, you need to turn the backlight down, but the OS only lets you turn it so far down (10/255 on my A43; some phones only allow 20/255) without directly writing to /sys/class/leds/lcd-backlight/brightness (which needs root, and is what SuperDim does).
I also suspect that in a dark area, with brightness set to a low value, lowering backlight will produce a more visually attractive image than Screen Filter, because lowering the backlight will make a black background be fairly black.
That's all for backlit LCD screens. OLED screens are a completely different kettle of fish, and SuperDim won't help you much there (though it'll still let you set themes controlling LEDs and ChainFire3D nightmode).
2. I generalized the code a little so it should let you control whatever LEDs your device has, as long as they have a /sys/class/leds/*/brightness interface.
3. By the way, ChainFire3D's nightmode is a touch imperfect: if you set it to red, I think it just turns off the green and blue channels. That means that green and blue visual elements cease to be visible. A somewhat better nightmode would convert the image from RGB to grayscale, and then turn off the green and blue channels. I don't know how easy to implement that would be--I don't know enough about GL blending (I tried to google but couldn't find an answer simple enough for me to understand).

I assumed it did convert to greyscale first before tinting, but you may be right. I'll have to think how to test that.

Quick test: If you set CF3D to blue, anything that's pure yellow goes black. For example, if you go to SuperDim, the left half of the brightness adjustment bar is yellow and disappears completely.
Another test: go with the browser to http://www.w3schools.com/html/html_colors.asp in red mode. Notice that the blue 0000FF and green 00FF00 samples can't be distinguished from 000000 black, while the red FF0000 can't be distinguished from white FFFFFF.

Seems like pretty clear results to me. I wonder if converting to greyscale first would even be feasible, from a coding, and from a processor cycle standpoint. It would have to use extra power, but I wonder how much. It doesn't really matter for me, everything I need to do is doable, but interesting nonetheless.

Another form of banding. Can you replicate?

Set wallpaper to black or go to a pure black screen with no icons on it. Bring up the "recent apps" and clear it out so that the overlay is blank. I notice heavy banding when the app is brought up over a pure black screen. Anyone else notice this?
it's hard to notice in a lighted room. go into a very dark room and you should see what I am talking about.
I've noticed this on transparencies. Could be a low quality image they used. Google has been known to limit the colors available to specific apps. Gallery and the Browser usually display crappy gradients. Perhaps this is another form of lowering the image quality so it loads faster.
As far as what your talking about, yes I can replicate it. Horizontal "sections" about equal distance apart. Hardly noticeable. I have to turn the lights off to really see it.
As long as the screen looks amazing when I'm using it and not in a dark room at weird brightnesses, I'm happy. This screen is super vibrant and bright. Who cares about a little banding on an almost black transparency that is requires a pitch black room to see.

Display getting darker when scrolling

Hello!
I recently got the Arc S and I love it, but there's something about the screen that freaks me out. It's hard to describe, but let me try.
When I scroll through menus, objects get darker while they move. Most notibly when there's white text on black background. I don't know many of you know it, but it's like applying the "inner shadow" filter to the fonts in photoshop.
I made a video to demonstrate that: http://www.youtube.com/watch?v=VVRTmsr6Ppg
Hopefully you can see the effect on the text, but it's very noticable that the lines between the items disappear while scrolling.
While on a grey background, text appears yellowish while scrolling.
I get a similar effect when I scroll through pictures.
Other than that, the screen is perfectly fine. I have a Neo V here with the same rom and kernel and there is nothing like that.
Or is this just normal screen behaviour I have to get used to?
What rom are you on?
Sent from my LT15i using birds.
if you look clearly at the screen, it is not getting darker! just the lines between the selectable touch fields are getting darker. dont know why but this problem is on all roms i have tested. it happens at small text and very small lines (1-2 pixel lines i think)
@TheHaso
Super Jelly Bean, Slim Bean, Ultimate HD.. It doesn't seem to matter.
@om22
So you think this is a software issue?
I noticed when I scroll through small turqoise text, it clearly gets darker and shifts into a more blue-ish tone.

no i think this is normal on tn-panel lcd screens (our arc/s). just a dark blurring effect i think.
If you want to get some information about TN displays vs IPS etc just follow the link:
http://en.wikipedia.org/wiki/Liquid_crystal_display#Twisted_nematic_.28TN.29
it's normal. only the lines get darker and not the text. this is how android makes it. try to increase the brightness and you will see that the lines gets a little darker.
But this effect does not happen at all on the Neo V.
And of course the text is getting darker, too. As I said, on black background a turquoise text shifts to blue while scrolling.

maybe because the neo v has built in another display? Our display also is very blurry in my opinion (high response time)

[Q] Super AMOLED - Black = off or still on?

I'm looking into purchasing the Galaxy Tab S 8.4, but one of my big uses is for reading on the Kindle app. Currently, on my LCD device I read with a black background and white text to reduce the light emitted as I do a lot of reading before bed, but it still is a lot of light which can keep my wife awake. Does the Galaxy Tab S actually turn off the pixels producing black, or is just very, very dark? I know AMOLED is supposed to turn them off, but I've heard conflicting reports that some devices do and some don't. Would someone be able to load up the Kindle app and set it to black with white text and let me know if it actually shuts off the pixels so it wouldn't be as bright in a dark room?
Thanks!
The Kindle app set to black background truly gives a black background, if set to use system brightness you can also get a very dim white for the text. If looking at something like the dark theme in Tapatalk you don't get black, the background is a dark grey. A bonus of running the kindle app like this is that battery life should be extended, compared to using a white background.

I could say that this is true black. Comoared to my old 7.7 which gives a slight glow when displaying pure black. This one seems like the screen is off

color change from lock screen to unlocked phone

Hello, I'm facing a sort of problem. When I look at the locked screen it has a calibration, but when I drop down the quick toggle or I unlock the screen it turns a little bit more yellowish. I don't think it's hardware related but could someone give me an explanation?
I think it's because of the FP sensor. To improve the recognition maybe.
Or it is a bug like the dark theme not being dark in some apps, Chrome, YouTube, Shelf. Top of the screen is less dark, like a little bit green. Not a hardware issue though, settings and built in apps ark dark (Dialler, Messages). I think it is something with the theme settings.
It's all normal. The lockscreen has this colder/blueish tone, like a filter, which goes away after unlocking. Nothing to worry about, not a bug or a defect. Just the way it's designed to work.

I don't think so.
With every app that request fingerprint authentication the color of the screen changes.
It must be something related to improve fingerprint accuracy
I am not talking about the screen with FP scanner active. Just check the dark themed Chrome, Shelf, YT. Especially on the dimmed screen. Upper part is a little greenish. Cannot make a screenshot as it looks ok on it. It has to be sth with theme, as on some apps (dialler, messages, settings) the whole screen is dark (black).

On picture we could clearly see green tint defect
Yep, and it looks like software issue to me.

As you can see, app is a little green, but quick settings are black when dragged down. Screen is fine, I believe.

Thats because green tint is only visible on certain brightness levels at grey background. No problem on black background
The issue related to the lock screen is present any time the through screen fingerprint camera activates. You will also notice it if you have face unlock active in low light and the screen lights up to assist the front camera in recognizing you. Color spectrum is super important to cameras when they are recognizing things on our skin.

That apps are not black, are grey. "Dark mode" does not mean "black".
In other way, all amoled panels have (or can have) this kind of behaviours at very low bright level and certain colours (especially grey).
Particularly, I do not see that effect in mine or I just cannot see it.
If you think that is a defect or problem, why not open a repair request to OnePlus?
