CF.lumen adapts the colors on your Android device based on the position of the sun, or your custom configuration. NOTE: Android 5.0 is now required. Versions up to v3.16 that support 4.4 KitKat are still available from the XDA thread (see far below). Performance drop since v3.60? Turn on performance mode. 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. During sleeping hours by default a red filter is used. Red strains your eyes the least, and retains your night vision. Light sensor 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 to experiment with. Color filters Several filters are provided. Those named after a color (red, green, blue, ...) do not limit the display to those colors, but convert the displayed image to grayscale first, then display that image in levels of the selected color. This preserves details that would otherwise be lost. Grayscale, invert colors, temperature adjustment and custom R/G/B adjustment filters are also provided. Colorblindness The master color filter setting also has an option for colorblindness enhancement, with settings for protanopia/anomaly, deuteranopia/anomaly and tritanopia/anomaly. These options in theory enhance clarity and color detail. No claims are made to the effectiveness of these filters. These filters were thought up by Google engineers, CF.lumen just includes them. Pro version Upgrading to CF.lumen Pro will support my developments, remove all nags, unlock the option to start at device boot (make sure you test your configuration first), and unlocks notification options. It also enables Tasker integration. In Pro mode, the notification adds convenient buttons to quickly disable the current filter or switch to sleep mode, and you can switch the notification to when enabled mode, which shows the notification only when a color filter is active. In non-Pro mode, the notification only asks you to upgrade to Pro. It may seem that notification is just there to annoy you, but it actually prevents Android from randomly killing the background service taking care of all the work. Getting rid of it without getting the service killed can be done by going to Settings -> Apps -> CF.lumen and unticking Show notifications. Having Chainfire3D Pro (ancient) installed will enable Pro. Performance When no color filter is active, there should not be any noticeable performance impact. When a filter is active, impact depends on device and what you are doing. On some devices we have tested there was no performance impact at all, on others it was slightly noticeable. It also depends on the driver in use. Future Keep in mind that Android's rendering system changes over time. You should be aware that this app may simply stop working on future Android versions without the possibility of a fix. Scary permissions By far most permissions are used only for Google Maps to set your location, and Google Play to provide for In-App Purchases. I cannot make any claims as to what information the Google components do or do not send to Google servers, but no information is sent to me or anyone else (than Google).

App ChangeLog
- Bare minimum(!) to somewhat support rooted users on Android 11. Rootless and injection driver have been removed as they are currently incompatible.

Update: I now have to disable it for some apps that don't allow apps to draw over screen. I do that, then re-enable. I use v3.7 cuz not rooted. ... I used this app for years, finding it after using f.lux on my computer for MANY years. Get PRO MODE!! This app is GREAT - VERY customizable (or auto), have never had a problem with it turning on. Has daytime/night/sleep modes that are super easy to postpone, turn off (for a short time or...) Can't say enough about this app! Awesome! Highly recommend!

Works great but when enabled on screen fingerprint scanner stops working. Maybe disable the effect when phone is locked?

Paid for it a full year ago and got used to it rather quickly. Wide range of settings that I mostly left alone because I just don't feel like it. Only one problem: the top of my screen (~2.5%) goes unaffected, so there's always a strip of regular color reminding me that the app is active whenever I look at it. Moto G4+ | Android 7.0

I have a rooted Nexis 5X running Android 8.1 Oreo. This app works well and fits my needs. Unlike Twilight, with this app, the blue light filter covers all parts of the OS, including the notification shade, lock screen, system bars, and even the ambient display. Also, the filter tint is much more natural compared to Twilight. This app also works better than f.lux on my phone. Overall, I'm very pleased with this app.

Since the update, it stopped working on my non-rooted phone. It appears this was planned, I assume because the developer lost access to maintain proper control on non rooted devices. But it has still left me heartbroken as I loved this app. I have chronic migraine and this has been the most helpful app I have ever had to maintain my ability to use my phone with a migraine. Truly a loss for me.

Even though this app probably won't receive updates anymore, as long as it's still functioning it's definitely the best blue light filter you can get if you have a rooted phone. If your phone isn't rooted, there are probably better options out there. But the colors and features you get with a rooted device make this by far the best choice.

I've used a lot of CF apps in my rooting days so I knew this would be a next level app, in terms of features nothing comes close. However it hasn't been updated for sometime & probably wasn't designed with 6" screens in mind because the filter doesn't cover the entire screen and leaves half of the status bar bright. Really hope you'll come back to this since there is nothing else quite like it. Thanks

if it works it's great, but I have to reset the filter a few times a day during transition time. somehow the app gets stuck and doesnt change the current value, until I change the master filter to red (example) and back to automatic. then it works again. Power saving is off for this app, aggressive doze off, and root access is allowed. OnePlus 3 on an older version of OOS, 5.0.5. I'll try to update it soon, maybe that'll fix it. if that'll fix it then ofc I'll edit this review :]

The custom RGB adjustment option is incredible and truly essential! Thank you! I was always dismayed by the lack of innate screen settings on my beautiful Samsung SAMOLED. The screaming contrast in dimly lit environments is just heart wrenching and eye watering. Now the screen can finally be calibrated into what it should have been from the start. Reducing and adjusting the RGB values individually is extremely useful!

Doesn't work because it keeps saying it needs permission to draw over other apps, even though that setting is enabled.
