Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a method and device for controlling a debugging port of a terminal device. Background technique

[0002] In a terminal device such as a smart phone or a tablet computer with an operating system such as an Andriod system, when the screen of the terminal device is locked, the user cannot directly operate on the terminal device or pass a USB (Universal Serial BUS, bus) port to connect with the computer to access the user data stored on the terminal device such as contacts, confidential files and other information. If the user needs to access user data, the screen needs to be unlocked first. After unlocking successfully, the user can directly operate on the terminal device to access user data. After the unlocking is successful, if the terminal device is connected to the computer through the USB port, the user can enable UMS (United Message Service, unified message se...
