Auto Brightness Switch is a simple and easy-to-use application for Android that allows users to switch on or off their device's auto brightness setting. The app is designed to save the last manually set brightness level so that users can return to that level when auto brightness is disabled.

Unlike other similar apps, Auto Brightness Switch is not a widget, so it won't take up extra memory or slow down your home screen. However, since it's not a widget, it also won't show you the current setting visually.

Auto Brightness Switch is open source and released under the GPL license, which means patches and translations are welcome. If you encounter any bugs or have feedback, you can contact the developer via email.

Overall, Auto Brightness Switch is a useful and lightweight tool for Android users who want to have more control over their device's brightness settings.
