While many Android phones come with onscreen navigation keys for Back, Home, and Recents, some phones, like Xiaomi Mi A1 come with capacitive buttons for navigation keys. These buttons usually have backlight to identify them quickly, but if you found the backlight extremely bright at night, you can completely turn it off, if you would like so. However, root access is required to achieve this.

Xiaomi Mi A1 is an Android One phone and unlike Xiaomi’s other Mi/Redmi phones, it does not have button light settings. However, with root access you can turn off the backlight on the phone. Thanks to the XDA member Emmanuel Bronze, all you need to install ‘SELinux Mode changer’ APK with root permission and install ‘Capacitive Buttons’ app from Play store to turn off the backlight.
