Yes, but the mobile phone needs to support the OTG function. Just use an OTG adapter to connect the mobile phone and the USB flash drive.
U disk, the full name is USB flash disk, and its English name is "USB flash disk". It is a micro high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to the computer through the USB interface to achieve plug-and-play. The name U disk originally came from a new type of storage device produced by Netac Technology, called "U disk", which is connected using a USB interface. After the U disk is connected to the USB interface of the computer, the data in the U disk can be exchanged with the computer. Since Netac has registered patents for equipment with similar technology produced later, it can no longer be called "USB flash drive" and is renamed the homophonic "USB flash drive". Later, the name USB flash drive became widely known because it was simple and easy to remember, and it was one of the mobile storage devices.
