Download CF.Lumen 3.0 Apk, A Chainfire tool with unrooted mode and freeload options.

The developers behind the most successful Android rooting app Chainfire has released the update for their screen modifying app CF.Lumen 3.0 which offers some very important changes needed for most Andriod developers as a useful tool for their works.

If you load CF.lumen on an unrooted device, it will automatically default to using the rootless driver. This makes changes to the color profile of the screen by adding an overlay, which is wham most apps of this sort do. The root method allows for much higher image quality, but the overlay gets the job done.

We bring the CF.lumen 3.0 Apk for our readers so that they can download and install it on their devices but before going to the download link we can read the official description of the app as stated in the Google Play Store.

CF.lumen 3.0 app features:

CF.lumen adapts the colors on your Android device based on the position of the sun, or your custom configuration.

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. (See f.lux for your PC)

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, amber, salmon) 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.


The master color filter setting also has an option for colorblindness enhancement, with settings for protanopia/anomaly, deuteranopia/anomaly and tritanopia/anomaly. These options redistribute colors across the spectrum, in theory enhancing clarity and color detail.

No claims are made to the effectiveness of these filters, but positive reports have been received from testers. Note that these filters were thought up by Google engineers, CF.lumen just includes them.
