The storage from the expansion slot on Samsung tablets generally integrates with the built-in storage, allowing you to store files and data on the microSD card. However, installing apps directly onto the SD card may require specific settings or configurations, depending on the device and Android version. Typically, you can move some app data to the SD card, but this functionality can vary between devices and apps. For precise details on how to manage storage and apps on your specific device, it's best to consult the user manual or manufacturer's support resources.
