A very bright display isn’t always the best option when using your mobile handset. While a bright display has its advantages, like improving readability, it’s is also a fact that a brighter display uses more battery power than a darker one. More so, you might not need a display that is too bright, for example at night, when someone is sleeping next to you, or when you are in your car.The Velis Auto Brightness app aims to provide the best brightness by using your smartphone’s sensors to determine the type of environment you are in. The app has total control of how much brightness is to be applied for any light condition by selection sensors used to customize the brightness graph.The app’s main display consists of two handles and a curved graph. Dragging the two handles changes the screen brightness and is based on different intensities of ambient light. For example, to save the battery life, you can make sure your screen never goes to 100 percent brightness, even in direct light.The app also lets users to set up custom profiles for different situations. The screen tends to change the brightness level when you switch through the custom profiles. Here you can choose one based on the situation you are in. You can save these profiles so that you can load them whenever the need arises.Moreover, Velis Auto Brightness app lets you define who sensitive you want it to react to light changes and if you want your device’s display to be brighter when your smartphone is plugged in.Notification is mandatory for this application because without it Android stops it too often. The application is available in 21 languages including English, French, Italian, Japanese, Portuguese, Russian, Spanish, etc.
