The USB Type-C port, or USB-C for short, is located at the bottom of a smartphone and is used most of the time for charging, data transfer and other purposes.  USB Type-C is A new interface standard that replaces the USB-A and USB-B interfaces that have been widely used for years. 
 
Because USB Type-C is a new interface standard, there may be compatibility problems between different manufacturers.  For example, some USB Type-C devices may not be compatible with older USB devices or require a specific converter to work. 
 
Because USB Type-C supports high power output and fast charging, it may cause security risks to users and devices if it is improperly designed or attacked.  For example, malware can obtain user personal information or tamper with data without authorization via USB Type-C interface.
