AMOLED themes are so good. If you want to squeeze even more out of your screen, you can use CF.Lumen to set everything to black and white ang get crazy SoT. Great for long bus trips or something like that.
Edit: Dammit link bot [link]
I can, very anecdotally, confirm this in fact makes a difference. I struggled with my sleeping pattern being all over the place and the phenomenon of "tired but can't fall asleep". I installed f.lux on my Windows machine and CF Lumen on my Android and after a few weeks my sleep is much more even. I genuinely get tired now, go to sleep and fall asleep within 10 minutes, and I don't remember doing that in years.
Filthy casuals. CF.Lumen master race checking in. It actually changes the hue of what's on screen and this is how f.lux on desktop works. Other apps that put a transparent window on top of everything which can also mean your banking app won't work for security.
You can also check out: Pixel Filter which can put a checker board pattern on your screen and thus reduce the brightness without changing the colour at all. Screen resolutions are so high these days that you won't even notice the blacked out pixels.
Depending on your habits as well. If you use your phone or computer a lot before bed that can affect your sleep patterns. I am basing this on the research that F.lux links to. I use F.lux for the computer and CF.Lumen for my phone. CF.Lumen unfortunately requires root (Android) but there are other alternatives that work well. Just not as integrated.
Also, you can stay up an entire day in order to be tired at a good time. I found this works well with traveling internationally.
He is probably reading it at a dark area, yellow lights is less harsh to the eyes. Check out lux or cf.lumen for Android. I prefer cf.lumen
Linkme! : CF.lumen
Edit : "CF.lumen" - [link]
I find CF.lumen better, especially if you're rooted. It just seems to mess with colours less, but still change the colour temperature.
If you're rooted you can go with CF.Lumen which doesn't face any of the restrictions that Twilight faces because it runs at a system level.
If you are rooted anyway, I would recomend CF Lumen for automatic screen brightness. Other than that, this list very closely matches mine.
Link me: Sleep As Android
Link me: Moon+ Reader Pro
Link me: CF.Lumen (bot will probably link wrong one)
Link me: Screebl Pro
Link me: Solid Explorer
Link me: Weather Timeline
I quite like CF.lumen. Not only can you tweak the brightness and dim the display, but you can even apply color filters as well. You can create different configurations for Daytime, Sundown, and Sleep modes (times configurable as well).
Basically, it has all of the features of the other apps and then some; very recommended.
Adaway and CF Lumen are my favorite apps that benefit from root.
If you've rooted your phone, I can recommend CF.Lumen. It works even more brilliant on phones because it puts a redfilter over your whole screen after midnight when you unlock your phone (you can turn it off too ofcourse)
No more being blind when checking your phone in bed <3
From the dude that gave you SuperSU, so you know it's quality software.
cf.lumen is pretty much flux for android, but more powerful. I have an all red filter for night mode, so my phone doesn't kill my nightvision.
Gorgeous eye-saving little tool from the mastermind chainfire. Works without root as well but with root you get the proper oomph
~~Linkme: CF.lumen~~ linkme got wrong link, thus edit:
If you use Android and are rooted, considering using CF.Lumen as it very closely replicates f.lux's settings (Twilight seems to be a weird red for me): [link]
Additionally, if you're willing to go really advanced then flash a custom ROM with KCAL support and use the CF.Lumen KCAL driver, this allows the transition to be performed natively by the LCD and as a result your screenshots will still be coloured normally and it also has 0 impact on performance.
Flux is straight up doing gamma adjustments (i.e. retains black colours properly etc.) while Twilight is basically just a yellowish semi-transparent overlay with a settings menu. If you want "true" flux-like capabilities you might want to try CF.lumen (if you're rooted).
I use "CF.lumen" to help me sleep earlier by tuning the brightness level automatically. So it doesn't hurt my eyes.
And "Easy app switcher" let me switch to recent app instantly by pressing floating icon.
In latest Samsung built-in keyword, there is a setting let you swipe over keys to move the cursor in text field. (Similar to swipeselection in jailbreak ios tweak). I think this is one advantage over other keyboards.
I use CF.Lumen to adjust my screen's color temperature at dusk and at night (here it's set at 2700k). Bright screens, both in brightness and color temperature, can fuck you up at night (keeps you awake, etc).
I make sure to use a kernel with KCAL support (Nexus 5) to get the best performance out of the awesome CF.lumen. Without it, recents cards and screenshots will have a color overlay.
Kurze Vorsicht: Twilight für Android ist Schott - hier gibt's eine Alternative: [link]
Twilight selbst setzt nur eine Plane über den Bildschirm - während lumen (und ähnliche) die Pixel selbst filtern. Außerdem frisst Twilight teilweise viel Strom.
If you have a rooted device, CF.Lumen is a better option as it works by changing the colours at software compositing stage, rather than drawing a translucent layer on top.
Also, vouch for Loop habit tracker.
FWIW, CF.Lumen blows Nightmode out of the water.
"Better audio quality" can be achieved by flashing ViPER4Android - but take that with a grain of something salty. The Nexus 6P has a pretty lousy DAC, so "better" really equates to smoke and mirrors.
There's no reason any ROM should degrade photo quality.
Unfortunately I can't help you with which ROM is best for battery life, but hopefully one of those tidbits is useful.
Before LiveDisplay was added to the nightlies, I was using Chainfire's cf.lumen app (by far the best in the Play Store): [link]
It provides the same functionality, but with more options. I'll go back to using that until LiveDisplay is added into a CM S release.
Edit: to be clear, this does not produce a screen overlay like many apps. It uses a system driver to actually change color temperature. It's the closest thing to f.lux for Android I've found.
CF.lumen. The rooted version does such a great job of adapting colors as the time changes. Makes using your phone in the evenings and dead of night so much more pleasant. The non-rooted version of any app like this just applies a orange/red filter over the screen which looks terrible.
Maybe you know about CF.Lumen made by famed dev chainfire, what's the difference between this implementation and chainfire's besides his being toggable at any time?
Edit: bot messed up, here's the link [link]
For Android, the best app (especially if you are rooted) I've found is CF.Lumen. It does claim to work unrooted as well, but I've never tested it like that.
You can tweak pretty much everything with it - the brightness, colour temperature, saturation, individual colour sliders, schedules, sensor activation or triggering it from Tasker.
The more common app is Twilight, but it doesn't change the colour temperature of the screen, instead, it overlays a transparent image on top of everything. It works but isn't as good of a solution.
If you're rooted, I recommend CF Lumen. It dims your screen just like f.lux does. It's made by Chainfire, the prolific dev who is behind SuperSU, CF-Auto-Root, StickMount, and other cool Android stuff.
Use it in conjunction with something like Darker to dim your screen further. Root not required but preferable.
Edit: Firstly, CF Lumen doesn't actually dim your screen. It changes the colour temperature at sundown, so it's less blue (which keeps you awake and messes up your circadian rhythm). This makes it appear slightly orange, but you get used to it very quickly.
Darker, meanwhile, does dim your screen. There are loads of apps that do this, but Darker is the best I've tried.
If you're not rooted, Twilight is very similar to CF Lumen. I used it before I rooted. I'd always use Chainfire's apps above any others though if you're rooted.
This thread inspired me to take a look, actually. I just installed CF.Lumen, but I haven't had a chance to try it out yet. Looks promising!
I had this problem too (it's a Lollipop thing). I'm using cf.Lumen now (made by Chainfire). It doesn't draw over the display so you can still hit pop-ups.
You'll have the best results if your phone is rooted but generally speaking yes, these apps do what they are supposed to do. Dimming blue light causes the display to strain your eyes a lot less during evening/night. I'd recommend using cf.lumen (best one IMO) or f.lux. CF.lumen works with or without root but as I said, root gives better results (like covering navbar and status bar, blacks being darker and not brown). Either way, you should at least give them a try, won't hurt.
CF.lumen is hands down the best screen filter.
It requires root to really function well. Android 6.0 broke its standalone root functionality so you need to use kernel with color control built in. Here's a basically stock kernel that supports root and color control if you need it: [link]
Once you have a kernel w/color control, just select "KCAL driver" in the app.
Edit: the period in the app name screwed up the bot. Here is a link: [link]
cf.Lumen is the closest we have at the moment. If you have root access, it's honestly far more customizable than f.lux. I've messed with it a little without root though, and I don't think I'd bother if I didn't have root access. Kinda makes everything brown.
There is CF.lumen and Lux for your warm filter needs.
EDIT: I just realized what you meant with the last sentence. CF.lumen is what I use since it doesn't use the filter on black like Lux does. Unfortunately this is an AMOLED panel feature and won't work on your device :/
If your rooted you want to use CF.lumen. This app is the closest thing to f.lux. If your not rooted you could still possible use it but it might be limited in functionality.
Link me: CF.Lumen
Edit: Go home LinkMe bot, you're drunk.
If you're on a rooted device, check out CF.Lumen, it's one of the best night mode apps.
On the PC, if you're on Windows 8.1 or earlier, check out f.lux. If you're on Windows 10 then it has a built-in night mode (I'd recommend adjusting the color temperature to make it a bit more warmer).
Twilight uses an overlay which puts a coloured filter over the whole screen. This means blacks and greys have colour added, making a very artificial look. Since it's done in post processing, they can be performance and quality issues.
I have the same phone and with root and CF.Lumen it looks beautiful, as good if not better than f.lux. I also am running Spirit Kernel to have access to the KCAL driver which means the filter won't appear in screenshots or be visible twice in the app switcher or other app previews.
Good explanation (and relevant user name?).
Twilight for Android is an inferior solution, unfortunately. It works as an overlay, meaning the screen content gets mixed with the overlay color (e.g. red) which leads to dark colors actually getting brighter (e.g. black turns dark red).
A better alternative is CF.lumen, but it requires root and might not work on all devices, as it installs a custom driver. It can also use the overlay mode that requires neither root nor driver, though.
There are apps that solve the blinding problem, like Twilight and CF.lumen which cut the blue tones at night, making the screen less harsh, and offer other automated or scheduled options, too, like specific brightness levels or activating whenever the surrounding light is under a certain brightness level, etc.
cool, until now I've used CF.Lumen but an open source app is better, of course!
Can Red Moon run without a notification?
EDIT: I also found Night Screen, which is on F-Droid, too. I'd love to know how it compares.
Bot sucks, link is [link]
Pretty neat app, can automatically put an overlay on the screen based on the time - if you change the settings a bit it should be possible to just dim the screen rather ~~has~~ than also tinting it orange.
CF Lumen at the play store could do it. I use mine to change the screen based on time of day. (Lower values at night, for example)
CF.Lumen all day every day. Allows you to adjust the color temperature, what color ranges you want to disable (for example you can make everything only rendered in shades of red, no blue or green whatsoever, or shades of blue or green and no red if you like your eyes bleeding). Used to use F.Lux but on my Pixel C running Remix OS it randomly snaps off when a notification pops up and it's basically like a flashbang at night. I'd recommend rooting to get the best experience, but it's not required. Plus it's a Chainfire app, and you can enable pro features without paying for it because Chainfire is an amazing guy.
Thanks for your help nearly 5 months later! However, this helped me in a different way than everyone else here.
I came across this thread while looking up how to enable Night Light on the S9. This is because I felt like Samsung's built in blue light filter wasn't strong enough. So, using both features in conjunction, I achieved a sort of two-mode blue light filter system, something that you can achieve with desktop apps like f.lux or Android apps like CF.lumen (however, the latter requires root access to look good, and there is no root method for Snapdragon Galaxy S9 as of now.)
How I have this set up is that a few hours leading up to my bed time, at 7:30pm, I have Samsung's blue light filter set to enable. Then, using this method, at 10:00pm, I have Android's Night Light set to enable also, making the effect more intense at bedtime. Then I have both set to turn off at 5:00. This allows a compromise between customizablity in the apps mentioned above and the better-looking filter in system blue light filters.
Once again, thanks for your help!
Even though it got added to iOS most recently, it's the best filter out there. After a week of use, you wont even notice the redshift and think it isn't working properly. Then you turn it off to test it, and your eyes hurt immediately.
Try CF.lumen it can function with, or without root permission, with root permission it controls your screens color through your kernel, NOT with an overlay. The reason this is so helpful is because normal filters put a semitransparent filter over the screen which actually causes the contrast to be greatly diminished and even the visual fidelity of images or small text can be slightly reduced, with it being ever so vaguely blurry with low contrast can also cause light eye strain, so if you have or can get root try that app out I swear by it
Extremely feature rich as well once you go through the settings :)
:) for night mode you can try this app
if Miravision is wanted i can make an add-on zip.
i will try to make some nicer icons in the camera app (settings in the right) and to set 1920x1080 as default instead 4K as video resolution
Yeah, it was. Then they did an os update and blocked that feature from the rather hidden menu option.
I'm currently using CF.lumen. it automatically triggers evening mode at sunset. Free with option to upgrade.
Näitä vastaavia ohjelmia on androidille kahta sorttia; toiset piirtävät ruudun päälle punaisen läpinäkyvän kerroksen (valkoinen muuttuu vaaleanpunaiseksi ja musta tummanpunaiseksi) ja toiset muuttavat näytön värilämpötilaa ihan oikeasti (valkoinen muuttuu kellertäväksi, musta pysyy mustana).
Jälkimmäisestä (eli paremmasta :) ryhmästä voin suositella esim. CF.Lumen.
Yep it's awesome
Makes it so you can use your phone at night in the dark without going blind lol same with fl.ux on PC
install CF-Lumen and change the temperature of the screen down a bit
This fixed my issues for the most part except at the on screen nav buttons. Those seem to be burned in somehow.
>There is an automatic mode that switches it on with the sunrise and sunset.
To start, yes, I know I will have the option to turn this off, but does anyone else hate settings that rely on sunrise and sunset times? Ever since the advent of the lightbulb, we have not been beholden to the light provided by the sun. It can be pitch black outside, but very bright in my house; I don't really want my displays to start getting red just because it's dark outside. I want them to get dim and change color when the room I'm in is dark. CF.lumen is the only app that works like this.
The link isn't working for some reason, try this
Or just search play store for cf.Lumen
2.I don't know if you can swipe them away or not I'm in a custom rom. But I think you can.
I'm saying all this assuming you have 5.1 as I never used 5.0.2 for long and most if the features and settings should be the same. And lollipop has superb battery, if for nothing else then stay for the battery life!
I used to use cf.lumen to do it, but now that I run CM13, it's built into the ROM and called "LiveDisplay".
If you're running stock, just give cf.lumen a go:
Ca sa fie singura, ar trebui sa te tina ocupat, e si mai nociva pe termen lung. As recomanda CF.lumen in loc de "prestare servicii" pentru ca ai picat deja la romana.
Another commenter mentioned using cf.lumen instead but didn't say why. Most of these apps add a tint on top of everything. Cf.Lumen instead actually alters the colors. For example, in most of the apps a black background with white text would become a reddish black background with red text. With Cf lumen it's a black background with red text.
You do need to be rooted for that functionality though.
Here's a link:
Completely different things. Neither Night Shift nor any versin of f.lux uses screen tinting or overlay. All the overlay variant of "f.lux" on Android also suck pretty badly.
You want an app which can change modify the white point of the screen which is unavailable without root on Android. If you are rooted though, this is the app you're looking for.
CF.lumen - Great app for adjusting display color to be more warm during sundown. Works without root, but the colors are much better if you have root. Especially the red filter with root, combined with an AMOLED display is great when reading in complete darkness.
Deliveries Package Tracker - Best package tracker that I've found. Supports tons of providers.
I like cf lumen better. It's works with or without root and has similar options to f.lux. But it's amazing if you do have root and install the necessary display drivers for it work at a system level.
With AMOLED displays you can essentially turn off all the blue LEDs with things like CF.Lumen, which wouldn't work nearly as effectively with an LCD. So I'm curious, what do you think makes LCD IPS displays better for your eyes?
Here's what it looks like. When you touch the "menu" in the app, you can choose between "disable", "wake" (force it to apply the sundown filter), and "sleep" (force it to red mode).
Just grab it and try it out: [link]
Caveat: As a security precaution, all screen dimmer apps have the effect that if you want to install an APK file (where it asks you to confirm or cancel the installation) the "confirm" button will be disabled. Turn off the screen dimmer app, and you can press that button.
I didn't like twilight and enjoyed Chainfire's app more as it was more than just a red filter. Reminded me of f.lux on iPhone
Linkme : CF.lumen
Edit - despite the correct formatting of the app name the bot is pointing to some Asian app that doesn't have anything to do with screens lol.
Cf.lumen from prolific Android developer Chainfire. It's for root users and kills blue light at night. Gives the screen an amber glow without using the overlays non-root alternatives use. It also gets me a lot of attention at the bar. Quite striking & helps me wind down at night.
Aside from f.lux, cf.lumen (also an Android app) has been on the market for a long time. It requires root and doesn't work equally well on every phone, but it's an absolutely excellent app and the most important one on my phone.
If you're rooted a better alternative may be CF.lumen
You might also enjoy CF.lumen!
I've stolen so many great app recommendations from these threads, I thought I'd share. Here's the apps that are making my devices whirr:
CF.lumen: Changes your screen colors based on the position of the sun. Runs better than Twilight. I'm also a huge fan of Chainfire. Requires root!
Falcon Pro: Hands-down the best Twitter app out there. Beautiful material design, too.
UP by Jawbone: No UP device required. The best counter & exercise tracker I've found. Syncs well with MyFitnessPal and also works great with my Moto 360 for step tracking.
Sunrise Calendar: I love the look and functionality of this calendar. I froze my stock & Google Calendars and just use Sunrise now. So customize-able.
Fuelio: Fuel log & costs: I use this app to not only track my fill-ups and mileage on my car, but mostly to track the maintenance I have done.
GassBuddy - Find Cheap Gas: I use this all the time to find out who's got the cheapest gas in my area. Every few cents counts.
Personally, I use CF.lumen.
Are you talking about this?
Probably uses an app like cf.lumen/lux/twilight to add a red filter, it makes the display easier on the eyes at night. It's sort of like f.lux on PCs/macs
Or if he's on cyanogenmod it could be the built in "LiveDisplay" feature.
CF.lumen is probably the best option, but it only works with root.
I believe this is it here
And they're still waaaaaaaay behind CF.lumen.
No, this is not the good app. Here is the link to the play store :
Ok, bad /u/PlayStoreLinks_Bot, I meant [link]
If you have rooted your android device, check out CF.lumen
May I recommend:
Twilight (for some reason CF.Lumen doesn't work on my tablet but Twilight works fine)
f.lux (for apple devices)
Sadly no. Waiting on ElementalX to be available on 4.0 and then I'll go the CF.lumen route.
I'd recommend CF.lumen over Darker - especially for anyone running a rooted device.
If you are rooted, try CF Lumen works and looks much better.
In the meantime, Chainfire to the rescue, as usual.
CF.lumen is a pretty good rooted alternative
There's a better one: CF.lumen.
And if you have a rooted android, get CF.lumen!
Se stai molto davanti agli schermi di computer/smartphone/tablet ti consiglio di installare un filtro per la luce blu.
F.lux per Windows/MacOSX, Redshift per Linux, CF.Lumen per Android, iPhone ha la funzione integrata ~~di cui ignoro il nome~~ Nightshift, con Windows Phone ti attacchi al cazzo.
Alcuni obietteranno che lo schermo poi fa schifo, c'è la patina arancione e bla bla, ma su di me ha fatto miracoli.
Io mi addormentavo fisso dopo le 3 di notte e mi alzavo non prima di mezzogiorno, ora a mezzanotte al massimo ho un sonno bestia e non mi alzo più tardi delle nove.
Se hai un Android ti consiglio pure di installare Sleep as Android, monitora il tuo sonno e decide quand'è il momento migliore per svegliarti. Io lo uso pure per i rumori bianchi e i toni binaurali, sembrano stronzate ma è una funzione a cui non riuscirei a rinunciare.
Ovviamente tutto ciò non ha un effetto immediato, dovrai aspettare mesi e cercare di puntare la sveglia sempre prima fino a quando non arrivi ad un risultato ottimale.
Nice try, but it's actually this one: [link]
For that last (sub-zero brightness), try CF.lumen.
I'd recommend CF.lumen over f.lux.
The Mac and PC versions of f.lux are pretty nice, but the Android version needs a whole lot of work and there's no sign of that happening. The most recent update to the f.lux app was March 15, 2016. Normally there isn't much value in the date of the most recent update (for example, CF.lumen was last updated March 30, 2016), but when the app is still in Beta, developed by a developer with no other Android apps, is missing a slew of features, and isn't even particularly stable... well that's a red flag.
Anyway, I could list all the ways CF.lumen is better than f.lux, but the apps really speak for themselves: Screenshots here.
I can appreciate that f.lux is "ultra-minimal", but this is one of those instances where the phrase ultra-minimal actually means under-developed. Nothing against the f.lux devs, but so far they've failed to recognize that the needs of mobile are very different from the needs of desktop.
As for battery drain, it's negligible.
EDIT: Added Google Play links.
Twilight is a filter that reduces the amount of blue light you're exposed to at night time, theoretically resulting in less eye strain, improved circadian rhythms, and better sleep. It's the Android equivalent of f.lux on PC.
more than 2 predefined profiles
adjustable transition time
option to turn off Twilight service altogether during inactive times
new features will often first appear as PRO
If you're rooted and want more control, you can check out CF.lumen
> Are you having trouble falling asleep? Are your kids hyperactive when playing with the tablet before bed time?
> Are you using your smart phone or tablet in the late evening? Twilight may be a solution for you!
> Recent research suggests that exposure to blue light before sleep may distort your natural (circadian) rhythm and cause inability to fall asleep.
> The cause is the photoreceptor in your eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range which may suppress Melatonin production - a hormone responsible for your healthy sleep-wake cycles.
> In experimental scientific studies it has been shown an average person reading on a tablet or smart phone for a couple of hours before bed time may find their sleep delayed by about an hour.
> The Twilight app makes your device screen adapt to the time of the day. It filters the blue spectrum on your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter. The filter intensity is smoothly adjusted to the sun cycle based on your local sunset and sunrise times.

Or CF.lumen. Cyanogenmod has a native method as well.
Is this what you are looking for?
It changes the color "temperature" of the display in sync with the time of day. Staring at the usual blue light tint of our screens can fool our bodies into thinking it is daylight, making it harder to sleep. By mimicking natural light, and gradually easing into a warmer color temperature, it can help prepare you body for sleep. Additionally it can just be easier on the eyes at night.
Try CF.Lumen app on your phone or F.lux on your computer. I haven't tried the new CM thing so I don't know if it is exactly the same.
I've always used Cf.lumen
Welcome. Here is a list of free apps:
AdAway (modifies your hosts file to block ads, needs root)
AFWall+ (whitelisting firewall, needs root)
Cf.lumen (modifies display brightness beyond darkest native setting, has 'freeload' checkbox, needs root)
PocketBook (best free ebook reader.)
QuickPic neutered (Gallery App, last version before it got bought by a chinese company)
And this is a list of paid apps i actually bought, might want to look into apks for these first:
Nova Launcher Prime (Homescreen app, you can have multiple of these installed and switch between them as you like. Also has a free version)
DraStic DS Emulator (Pirated it first. Best DS Emu on Android.)
Moon+ Reader Pro (Best paid ebook reader on Android. Also has a free version.)
Titanium Backup PRO (Best backup app on Android, requires root. Also has a free version.)
Sync for reddit (Arguably the best reddit app on Android. Also has a free version.)
Type Machine (A keylogger for yourself. Still working but seems to have been abandoned.)
CF.lumen if you want a little more control.
For rooted Android users, CF.lumen
this is the best one out there. but you need root to get the real colors, otherwise it looks bad
If you have root I can't recommend CF.lumen enough. Save your sleep schedule!
I prefer C.F.lumen. It's exactly what f.lux is.
Some other non-root apps:
cf.lumen is an alternative that works a bit better. You need root to use it, though.
Sure, all other apps do exactly that.
CF.lumen can work like this too, without root.
Also I used Lux in the past, it was good but it isn't updated for some time. I also heard goor things about Twilight.
As for root apps — instead of adding overlay (adding or subtracting some constants from RGB values) they directly change display color profile (multiplying RGB values). That greatly increase image quality. Take a note if you ever going to root your phone.
The big prerequisite is that you have to be rooted, but other than that you just install CF.lumen and customize the settings however you'd like.
FWIW, here are my settings.
CF.lumen was actually the sole reason I rooted in the first place, and the whole process turned out to be infinitely easier than I'd anticipated, thanks to Nexus Root Toolkit. Then on top of that you can get system-wide ad blocking with AdAway, which is absolutely glorious.
If you have root, you can use cf.lumen on android for a much more f.lux-like color adjustment.
Or CF Lumen
Yes, there is. You would need Magisk, phh's root, and Systemless Xposed. I used to use them but I went back to non-systemless because the Magisk Manager app's toggling and stuff were annoying.
If you're having problems with "bricking" your phone you're most likely doing something wrong.
By the way, if you want f.lux I recommend CF.Lumen instead because it's better and has more features.
Just to double check you don't have CF.Lumen installed either, right?
I believe this app by default throws in a yellow tint.
cf.lumen + lux auto brightness
[link] if you have an android phone.
If your phone is rooted, check out CF.Lumen. It does it the proper way and looks fantastic!
Why f.lux over something like cf lumen?
Something similar that works on Android: CF.lumen
Nope, that's not it.
This is the one: [link]
Seriously? Way to fail bot.
It needs root to work but it adjusts everything on the screen
cf.lumen for max customisation.
had those reboots also because of f.lux, switched to cf.lumen instead, no issues atm.
Isn't this aka cf.lumen
if you have root
Right Link Cf.lumen the bot has failed me
SunsetScreen is just awesome.
For Android try CF.lumen:
Are you rooted? Try CF Lumen if you are.
Just use cf.lumen then.
You might want to try CF.lumen. It works in a similar fashion as F.lux on iOS, provided your device is rooted.
CF.lumen, works best if you have root.
CF.lumen integrates with Tasker and supports KCAL.
There's also CF.lumen.
Cf.lumen works great too
CF.Lumen .. It reduces eye strain after sunset. Great app! [link]
Edit: could also be lux, but cf lumen's overlay is better

I still like you Mr. Bot.
I use CF.Lumen. It's fantastic!
Cf.lumen interfaces directly with the display driver and doesn't use an overlay. You need root though.
Works much better than Twilight does if you are rooted.
SunsetScreen for PC's
CF.lumen for smartphones
Outside of the advice already given, use the following software to adjust the temperature of your computer / phone:
You can also use Lux Auto Brightness (Android) to take down the brightness of your screen below the normal levels. It's great for at night and pairs well with CF.Lumen.
I've got the same sleep pattern as you. I love being up until about 4am, but often I get into a project and hear cars leaving for work.
Cf.lumen - Price: Free - Rating 4.5/5 - Search for "cf.lumen" on the Play Store
The actual link to the app for anyone interested.
I just screwed around with this, and here's what worked for me. You'll need:
Then, launch Tasker and:
To reverse this, you could easily repeat the above steps, but in the task you'd pick CF.Lumen -> Disable Filter. Then, you'd obviously rename the task, give it a different app package name and assign its execution to another button/combo.
I hope this is easy to understand, since I don't often try to write tutorials. If you need any clarification, let me know!
EDIT: So, I checked and the CF.Lumen step does require the paid version, since that opens up Tasker integration. I gotta imagine there's another way using all free apps, but maybe someone else has some suggestions?
I don't know about F.Lux, but if it works anything like CF.Lumen, then no. Back when I used CF.Lumen, it's battery usage was negligible.
As recomanda CF.lumen in loc de Twilight. Twilight decat pune un overlay rosu peste ecran, CF.lumen scade temperatura culorii, la fel cum face F.lux.
[Insert explanation about how cf.lumen is the actual android app you want to get]
> Red Moon protects your sleep by filtering harmful blue light from your screen
As far as I can tell, this does not actually filter anything out, but instead adds a red-ish overlay over the screen, correct? That would mean it's not a real alternative to CF.Lumen
