Xiaomi’s current smartphones have impressive specs, but internal memory is often lacking when you’re using the camera and installing heavy apps. When the storage gets crowded, the system starts to run slower and there’s nowhere to store new images, and in this situation, the best solution is to use external drives.

Unlike cloud services, a physical medium does not require the Internet and ensures that your files remain confidential. OTG (On-The-Go makes this process as simple and accessible as possible, even for beginners.
Owners of devices with a MIUI shell or a new HyperOS can manage files directly through a standard Explorer without installing third-party software. Below we will discuss in detail all the ways of connecting, settings and possible nuances that you may encounter when working with external drives.
Preparation of equipment and compatibility check
Before you start copying files, you need to make sure that your smartphone is technically capable of interacting with external devices. Virtually all modern Xiaomi models, including the budget Redmi and POCO series, support the USB OTG standard. However, physical connection can vary depending on the type of connector.
If your phone has a USB Type-C port, you’ll need either a USB flash drive with the appropriate connector or a special adapter. Older models with a Micro-USB connector will require a similar adapter, but with a different type of connector. It’s critical to use quality cables and adapters, as cheap counterparts may not provide the necessary current for the drive to work.
