How to control the brightness of your display on your Android device

Changing the brightness on your Android can seem like a no brainer: go into your settings and adjust to level to your preference. However, this might not be enough to save battery power on your device, reduce the brightness to a proper level to not harm your eyes, or provide an optimal brightness based on your lighting conditions. To better manage the brightness on your Android device, you’ll have to go above and beyond your settings.

Change the brightness according to ambient light

To change the brightness according to the ambient light around you, you can use the Lux Lite to manage it for you.

Lux Lite Install on Google Play

With this application, you can go ahead and change the brightness manually, but it still offers you more customization options than your standard Android settings. Lux Lite allows you to go beyond the preset options and offers you a bunch of profiles to help your device adapt to changing light conditions.

The app does provide in-app purchase to unlock some advanced features, but the basic options are still very useful and can manage the brightness extremely well.

Manage your display colors and contrast

With the Twilight app, you can change the color shades and contrast based on the time of the day.  

Twilight Install on Google Play

If you want enable automatic adjustments, go to Filter Times and adjust the contrast based on the time of the day.

The free version of Twilight doesn’t allow you to manually change the times of sunrise and sunset or use custom transition times to switch from a warmer display to a normal brightness. For this, you’ll need to upgrade to the Pro version.

Adjust brightness at night

When you are looking at your display at night, it can often be way too bright for the good of your eyes. In order to optimize the brightness so that you can both see whatever is on your display and not burn out your retinas, you can grab the application called Night Mode.

With Night Mode, your device will automatically reduce the brightness based on the time. All you have to do is set a start time and an end time and then the app will do the rest for you. As well, you can disable a bunch of different settings on your device based on the time including your notification light, haptic feedback, notification sounds, and more.


Whether you’re looking for a custom ROM or already running CyanogenMod, you’ll be please to know that it offers more advanced options for controlling the brightness on your device. You can have the brightness automatically adjusted based on your ambient lighting. Simply head to Settings > Display > Brightness in order to enable it.

Root Permissions

If you’ve already got root permissions on your Android device, then you’re one step closer to having complete control of your device.

RootDim is an app that allows you to adjust the brightness on devices with LCD screens much more thoroughly than what Android itself will allow.

Of course, you can also “tweak” your device and manually change the minimum levels of brightness. You’ll need to have a file manager, such as ES File Manager or Root Explorer, and head over to the system and modify the ro.lcd_min_brightness.

  • I swear by Lux (paid). I set up auto day/night mode that works of my location so it knows when sun up and down are and adjusts min & max levels accordingly. It also allows my Note 3's amoled screen to go into "subzero mode" where it drops well below stock 0% brightness....very useful. My phone never goes above 40% brightness unless I'm in bright direct sunlight. It also allows for plug in support of cf.lumen and a plug in to help users with Nexus 5 battle auto adjust problems.

    Get the paid/donate version it's worth it!

    Another app that i would recommend is 'Darker'..
    It works well, saves battery and has most of the features mentioned in this post.

  • Some Prestigio tablets come with Android 4.2 and do have an "automatic" setting for brightness that does watch the ambient light and dim the display acordingly. How do they do it?

  • I recomend gravity box, it has the very good oneplus one's function that allow you to adjust the bright by sliding your finger on the status bar. Only this, very useful and simple.
