7 Best Android App For Brightness

1. CF.lumen

Download the App on the Google Store by clicking this Button
“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).

2. Twilight: Blue light filter

Download the App on the Google Store by clicking this Button
“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. See references below..

The Twilight app makes your device screen adapt to the time of the day. It filters the flux of blue light emitted by 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.

Get more from Twilight
1) Bed reading: Twilight is more pleasant on the eyes for night reading. Especially as it is able to lower the screen backlight far below the ability of the backligt controls on your screen

2) AMOLED screens: We have tested Twilight on an AMOLED screen for 5 years without any sign of depletion or over-burning. If properly configured Twilight causes less light emission (by enabling dimming) with more equal light distribution (dark areas of the screen such as the status bar get tinted). This may in fact increase your AMOLED screen life time.

5. Velis Auto Brightness

e-mail: jure.erznoznik@gmail.com

Note: Notification is mandatory for this app because without it Android will stop the service too often for too long. There’s no use in auto brightness if it doesn’t work half the time. So before you give a one star review, consider this fact and my assurance that I’m trying to find a more user-friendly way. I will no longer respond to “it has an ugly notification” type of ratings.
Also please see homepage about language support. Any translation help most welcome!

Velis auto brightness aims to provide the best possible brightness experience by using your devices sensors to determine the environment you’re in. You have complete control over how much brightness will be applied for any given light condition, from selecting the sensors used to fully customizable brightness graph. This is a replacement for system provided auto-brightness functionality usually found in Settings / Display / Brightness

Features:

– Initial configuration wizard for an easy start
– User-selectable sensors: light, proximity, cameras
– Supports custom sensors on phones such as Sony Xperia, SGS 2
– Brightness presets for every taste and screen
– Profiles (save the brightness graph under your own name)
– Fully customizable brightness graph to fit your needs or cover your sensor’s faults
– Extensive sensitivity adjustments (light change threshold, smoothing times up / down, boost threshold)

“Yet Another Auto Brightness (YAAB)

A small application designed to enhance user control over screen brightness. Initially it was developed to make the screen as dim as possible to save battery.
It has ascetic interface and very simple in use.

Tap “Start”, adjust brightness using slider control below the buttons if needed. That is all. Application will run in background and change screen brightness according to current light sensor data and manual adjustment slider position.

Please do not try to use multiple custom brightness control applications at the same time. It leads to unpredictable behavior.

The application is open source. Source code and issue tracker are available here:

We are open to bug reports and feature requests.”
