Mobile Data Switch is a free Android app developed by RYO Software that provides a simple interface to control mobile connectivity. It includes a widget and a shortcut in the status bar for easy access. However, it only works on rooted devices running Android Lollipop or higher.

One of the app's key features is the ability to automatically disconnect mobile data when the screen is turned off and re-enable it when the screen is turned on. Additionally, the app includes settings to customize this behavior to suit the user's needs. It's worth noting that if there are any requests pending, the app includes a 5-second delay before processing them.
