The USB-C interface of the Samsung Galaxy A55 supports the USB-C standard, but the specific details of the USB version are not explicitly stated in the sources provided. However, it is common for modern smartphones such as the Galaxy A55 to have a USB-C interface that usually supports USB 2.0 or higher, but often without a specific indication of the USB version.

To get exact information, I recommend consulting the official product description from Samsung or the user manual.
