The free version of Darker (Screen Filter) does a decent job of blocking the light on your phone's display. But if you'd like more advanced features, you can purchase the paid version and enjoy some premium features. These features include a custom command set that lets you send commands to your phone via FlickStart, an app you can download for free. These apps let you control your display by dimming the status bar and changing the brightness level of your screen.
Although Darker does not feature many advanced features, it will reduce the amount of bluelight on your screen and prevent eye fatigue during low-light environments. You can use it without any trouble if you want to avoid the harsh white backgrounds caused by high-resolution displays. In addition to reducing the brightness of your screen, it also adds a color filter to help prevent eyestrain and protect your eyes from strain. The free version is fully functional and comes with a number of additional features, such as a UI and a built-in keyboard.
For Android devices, you can enable the Dark theme by going into the Settings app and selecting "Customize controls." You'll notice that many popular apps, like Facebook and Twitter, already have this feature. If you're a Firefox user, you can install a dark mode by enabling the developer mode option in the browser. To use the dark theme, you need to have a rooted device. To install the application, you'll need to enable developer mode, which is not difficult.
