Storage Info is a utility application designed for Android devices, specifically optimized for those that support USB-OTG functionality. This app primarily serves as a shortcut to access storage settings, allowing users to manage USB mass storage devices more conveniently. It is particularly beneficial for users of Sony Xperia V, where it addresses the lack of a quick unmount option for attached USB devices. However, due to recent Android security restrictions, the app may not always be able to directly unmount devices and is recommended for use with rooted devices for full functionality.

The application facilitates the creation of notification shortcuts that direct users to the default storage settings, enhancing the ability to manage external storage. Users can also select a preferred file manager to launch when a storage device is connected. While the app is free and open-source, it is essential to note that it does not provide USB host support and is intended for specific devices. Users should be aware of potential limitations depending on their device configurations.
