The same thing happens when using the CF.lumen root driver on my SHIELD Tablet.
If you're rooted and have a Snapdragon or Tegra device, consider trying f.lux. f.lux comes with three drivers: Compositer, Qualcomm, and Tegra. The Compositer mode will likely behave exactly the same as Android N's night mode, but Qualcomm or Tegra drivers may result in Netflix and Hulu working properly. Using the Tegra driver on my SHIELD Tablet allows Netflix and Hulu to work while having night mode.
And f.lux for Android is better than CF.lumen too, I did a comparison between CF.lumen, f.lux and twilight and I found that f.lux had better accuracy in colors. Root only: https://play.google.com/store/apps/details?id=com.justgetflux.flux
And its also in beta. I also cannot get CF.lumen to work in Android N so this is my only option left.
f.lux is on the playstore as a preview build that is root only. Very early in development, but has potential if they get it up to where the desktop version currently sits.
The only problem is that Netflix and Hulu do not work for me with the the rooted CF.lumen driver. f.lux on the other hand comes with a Tegra driver that I can use with my SHIELD Tablet to allow Netflix and Hulu to play videos just fine.
I still use f.lux because of its awesome darkroom mode (inverted colors + red). You might have to switch display drivers (in its settings) for it to properly work though.
Yes. Apps that don't have root access can only create a overlay instead of actually reducing blue light. This can actually reduce blue lights
You should get rid of it asap. Twilight is proven to be scam. It doesn't filter the blue light out. It just pretends to by using a red layer. There is only one app on google play store that actually filters blue light out and it's called i.flux. However it needs root access. Filtering blue light out does require root on Android, hence why apps like Twilight that doesn't require root are fake. You can read about twilight being fake somewhere on the i.flux forum.
Hmm, I'm actually quite happy with flux so far (w/ root). This is a good price, however. Anyone tried both?

F.lux recently opened up its Android beta and has posted the preview version on the Google Play Store
I believe f.lux does what you want, although I'm not sure about tasker integration. However, chainfire did say he will be open sourcing his apps, so maybe there will be a forked version of cf.lumen in the near future.
Edit: sorry, misremembered it, he said he would look into open sourcing, so it's not definite
Android users:
If you have Nougat on your phone, use Night Mode, if not, but you are rooted, try f.lux otherwise if not rooted try Twilight.
iOS Users: f.lux is your friend I believe...
These apps aim to reduce blue light after sunset - I find it a bit jarring personally, but it is supposed to allow for a better night's sleep after being on your phone in that inevitable period...
> not sure what op is talking about
The fact that f.lux says, right in the play store as the title, "f.lux (preview, root-only)"
Edit: link https://play.google.com/store/apps/details?id=com.justgetflux.flux&hl=en
F.lux for rooted Android devices is available on Google Play. Its stated to work well on 5.x and 6.x, but ime anything 4.4.2+ should work fine. :)
The OP3's default color temperature is so easily changed that your comment is meaningless.
Going further, you could try an app to do it automatically depending on time of day. Colder white is good in daytime but at night a nice warm white is easier on the eyes.
Here's the Reddit post: https://www.reddit.com/r/Android/comments/4aerng/flux_released_to_the_public_on_the_play_store/
and the Play Store link: https://play.google.com/store/apps/details?id=com.justgetflux.flux
Use f.lux if you actually want to change the screen's color temperature instead of just slapping on an overlay.
There is f.lux for Android
Changes:
> v20 tries to minimize the number of times f.lux disables when there is not protected content on the screen
Edit: There seems to be a bug in this version where f.lux keeps flickering on and off (with the compositor). This isn't occurring in v19. I've switched back to the old version for now.
~~Note: The Play Store version hasn't been updated yet (still on v19 as of posting this).~~
Edit 2: f.lux has been updated to v21 - grab it from the Play Store.
v21 fixes some crashes and the Chrome flickering issue.
Edit 3: f.lux has been updated to v22 - grab it from the Play Store.
v22 fixes the black-screen-of-death issue when the device is booting up.

For Android: https://play.google.com/store/apps/details?id=com.justgetflux.flux
If your Android phone isn't rooted you can try using either Red Moon (open source but the Google Store version isn't free) or Twilight.
For iOS you got a feature called Night Shift which works the same way.
Or don't pay at all: f.lux ($0.00 US)
Lacks some customization for now, though.
There's also f.lux which is literally f.lux for android.
Great post! I meant to make a similar one earlier, but never got around to doing that, haha.
I'd love to contribute a bit more information to this thread, after running the GSI for a couple months on my Essential Phone:
The Android 11 GSI lacks an option to disable the charging LED, which I found a bit annoying. So I made the following Tasker task that will disable the LED while charging:
The option to disable grip rejection is missing from Developer Options, but I found that running the following command in a root shell will disable it:
setprop persist.grip.status_manual 0
Make sure to reboot your device after running that command.
Night Light isn't enabled on the GSI, but the f.lux app works great instead.
The Essential Phone's backlight won't get nearly as dim on the GSI as it does on stock Android 10. The Screen Dimmer app is a decent workaround - it won't actually lower the brightness any further but it will dim the contents of the screen to achieve a similar affect. (This app will dim your notifications and lock screen as well, something that most other screen dimmer apps won't do)
Finally, I noticed that video recording is broken for most apps using the Android 11 GSI. Videos will appear to record properly, but the actual files that are produced are corrupt.
It's pricey, but the FiLMiC Pro app is the only one I've found that doesn't produce corrupt video files.
Well f.lux and CF. Lumen both need root to function properly because they change the color temperature whereas Twilight, Lux or Red Moon are just overlays. It's actually pretty noticeable if you compare them.
Directly from the official FAQ >Plenty of things already change the brightness of my screen. Why is this different? f.lux changes the color temperature of your display. Natural light is more blue, while most artificial light (including candlelight) is warmer. Incandescent bulbs, which we're all used to, become more red in tone when you dim them. But newer LEDs and CFLs don't - this includes the backlight on your monitor. If you're a photographer, you've probably dealt with this, since pictures taken inside at night are always much more brown than photos outside.
F.lux Google Play store listing >f.lux removes the bright blue colors from your phone to help you wind down at night and returns your screen to normal the next day. This preview version is not a final release. It requires a rooted phone, and otherwise it will not do much.
Not official but a old thread from /r/Android about f.lux
A few comments stick out such as this one >Nearly all Android apps that do this (tint the screen red for "night mode") use an overlay. You can think of it as a translucent, colored foil being placed on top of the screen. This has one big disadvantage: it actually makes dark colors brighter, i.e. the exact opposite of what you want from a "night mode". Black + dark red overlay = brown, for example. Just take a look at this screenshot compared to this one. In the first screenshot, status and navigation bars are pure black, as they should be. In the second screenshot, an amber-colored overlay is active, which is supposed to reduce the blue light emissions, but as a side effect of the overlay method, it also raises the black level and makes everything look "flatter" (reduced contrast). The only overlay color that does not have this problem of raising black levels, is black - some of these apps use black overlays for "artificially" reducing the brightness below the lowest backlight brightness setting, without affecting the tint. If you want to "properly" adjust the colors, you have to manipulate the RGB values directly instead of using an overlay. But this requires root access (edit: or customized firmwares or kernels). CF.Lumen is the only app that I know which actually supports this superior method for a variety of devices, without customized firmwares and kernels. If f.lux for Android requires root, that indicates it'll actually use the better non-overlay method, too. PS: The latest version of CF.lumen, v3.62, has some problems, because the app is going through a rewrite, see the xda topic. If you'd like to give the app a try, I'd recommend v3.16, which still is the latest one for Android 4.x users anyway.
Android Police >The premise of apps like this is that blue light can interfere with your sleep cycle, so it's best to filter it out in the evening. There are a few Android apps that do that like CF.lumen and Twilight, although the latter uses a non-root red overlay that may or may not work as well as the root methods. f.lux includes scheduling, various color temperature features, and more.
CF. Lumen Google Play store listing >When using the default settings, your display will get a warmer tint (lower color temperature) when the sun is down, vastly reducing strain on the eyes. Blue light makes your brain want to stay awake, and a lower color temperatures reduces the amount of blue displayed; using this in the evening reduces your brain's effort to keep you awake at night.
Official XDA post >The light sensor can be used to automagically adjust the color: switch to the sleep filter in full dark, or to the day filter (usually none) under bright lights. Because light sensor quality varies wildly between devices, a calibration option is provided. Most devices seem to work fine with sliders set all the way to the left, others need them to be set all the way to the right. Experiment as needed, but be warned that some devices simply cannot distinguish between evening indoor lighting and full darkness, and this feature may thus not work well for you.
If you have a rooted phone, you can use f.lux: https://play.google.com/store/apps/details?id=com.justgetflux.flux
Probably a copy-protection issue. Google Play Movies does the same thing for me with f.lux.
Apps Like Twilight, Lux, or Red Moon DO NOT do the same thing as F.lux or Cf.lumen. Apps like Twilight just have a orangy or red overlay to your phone where F.lux or Cf.lumen actually change the blue light coming from your phone.
To answer your questions:
Rooting a Nexus 6P is very easy, I just followed this guide from XDA Unfortunately if your bootloader isn't already unlocked you will have to wipe your phone.
Once you're rooted you can install F.lux or CF.lumen directly from the Play store.
I can't really comment on how either of these apps damage your phone's display, I've been running f.lux on my phone almost since I got it with no issues that I've noticed. I would assume they are safe since they included Night light in Pixel devices. Hope that helps!
Try https://play.google.com/store/apps/details?id=com.justgetflux.flux
I use that as well on my phone.
Guess for Iphone you've similar apps.
Pro tip: if you have root use F.LUX: https://play.google.com/store/apps/details?id=com.justgetflux.flux
It's not just an overlay and looks way better
Yeah! I think it's it's a beta: https://play.google.com/store/apps/details?id=com.justgetflux.flux
you need root though. It also is a jailbreak tweak on iphones.
f.lux is far beyond anything else but, like cf.lumen, you have to be rooted.
It's been a long time since I have been on Android but is flux not used anymore?
how similar is the code to the original f.lux? which i just discovered is now available for android lol https://play.google.com/store/apps/details?id=com.justgetflux.flux
Android already has f.lux beta.
I used it for quite some time before getting my iPhone 7 plus.

>Pretty much flux for Android
FYI f.lux is now available for android and is very great
Yes I found. F.lux was causing this.
f.lux (preview) for android is very good. https://play.google.com/store/apps/details?id=com.justgetflux.flux&hl=en
F.lux is in the Play Store, why it wouldn't be? https://play.google.com/store/apps/details?id=com.justgetflux.flux
Android has actual f.lux. Requires root though.
Link to play store? I can't seem to find it...
Edit: Found it
