Night Mode APP
The interface in Night Mode is quite simple and lets you pick the color of the filter to modify your screen brightness. You'll find, for example, orange light filters or others that balance the white pixels that appear onscreen.
If you want to keep your Android's backlight from causing bouts of insomnia, Night Mode is a simple tool to add a filter that adapts the brightness and color warmth so you can look at your smartphone in complete comfort during the evening hours.
