    Lux Auto Brightness's review

    Published: 2012-04-27, by .

    Lux is a custom auto-brightness app that adjust it depending on the brightness of your environment

    • Create brightness profiles
    • Lots of features
    • Auto-brightness detector using light sensor
    • We didn't find any, did you?

    "Smart battery saving"

    Smartphones screens are now larger while batteries don't keep it up. For this reason, we need to make an effort by keeping track of those features that leak battery most. The jewel of the crown of battery draining is, of course, screen brightness. Lux is an app that comes to automatize brightness preferences depending on the environment.

    It works by linking the brightness of your surroundings (ambient light) with the brightness of your device's display. The ambien light is obtained via the light sensor installed on your device (usually above the display). From the dashboard you can produce linked samples (profiles), toggle astronomer and night modes and access to preferences.

    Likewise, you can create different levels depending on the amount of ambient light that camera catches, which is quite util for a more accurate performance. There are other extra features like: keeping the brightness 100% while charging, a handy widget for an easy management (enable/disable automatic mode, switch between profiles, etc.)

    The main catch is that its free version is almost a demo since it is quite restricted. Anyway, the app is worth and if after giving it a go you like it, you can upgrade to the paid version which costs just AU $1.49.

    The original custom auto brightness solution for Android.

    "To put it simply, Lux kicks the pants off of Android’s stock brightness manager, and it’s worth every cent." - Lifehacker

    "Lux is a third-party app that allows you to easily calibrate your phone’s brightness sensor, saving you battery power and reducing eye strain if your phone is normally too bright in dark rooms." - HowToGeek

    Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If you step into a dimly lit room, Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.

    Lux is also able to adjust the screen temperature of your display automatically to make it appropriate for night usage. At sunset, you can have Lux automatically warm your display and switch to your Night profile. If you're an astronomer, you can enable astronomer mode to cut out harsh white light. If you have a root enabled phone, you may even be able to apply these enhancements at a low level with Lux's plug-in system.

    Perhaps the best thing about Lux is that you can teach it how to behave. If the backlight is too bright or dim for your liking, simply open the provided Dashboard, adjust the brightness slider to the level you desire, then hold the link button. Lux will use this new 'link' as a reference in future.

    Give it a go! I want you to test Lux for more than the 15 minute refund period offered by Google. I understand that some devices may not have the best quality light sensor, and that you may need more time to play around with settings. If you find that Lux doesn't suit you after the 15 minutes is up, you can request a refund within a week of purchase via e-mail - no questions asked.

    Stable, custom auto brightness with root plug-in support.

    Always loved this, but auto brightness and night mode do not work on my Galaxy S8+.

    LG G6 works perfect, but .. y all the permissions? Been using for years on Kit Kat 4.4. Now on 7.0. App interferes with my VPN, so I killed all of Lux's permissions, and now my VPN works (PIA), and Lux still works perfect for me. This is the first app I install. 5 Stars.

    Very good app, but in the cases I need to turn it off or deactivate it how do I?

    The app is great but it drags my phone to a near standstill (both using the regular overlay and alternative overlay). If I turn it off and stop the app my phone runs fine, when I re-enable it my phone gets slower and slower, particularly when unlocking the phone. I had to uninstall this, which is a shame as the other similar apps are mostly plain awful.
