Abstract

The invention provides a method and a device for protecting a mobile terminal. The mobile terminal is configured with a configuration channel detection module, wherein the configuration channel detection module is in an uplink port mode, and the method comprises the steps of: receiving an operation instruction for performing mode switching on the configuration channel detection module; switching the working mode of the configuration channel detection module from the uplink port mode to the dual role port mode according to the operation instruction; and switching the working mode of the configuration channel detection module from the dual role port mode to the uplink port mode when detecting that the usage state of the mobile terminal meets the preset condition. In the embodiments of the invention, since the mobile terminal acts as a slave device by default, the problem that the working mode of the channel detecting module is misjudged due to impurities or liquid entering the USB Type-Cinterface, and the mobile terminal cannot be charged is avoided.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a method and device for protecting a mobile terminal. Background technique [0002] The new generation of USB (Universal Serial Bus, Universal Serial Bus) TYPE-C interface has the advantages of supporting positive and negative insertion, stronger power transmission, faster data transmission speed, and slimmer design, so it has gradually become the preferred choice for mobile terminals. standard interface. [0003] The CC (Configuration Channel configuration channel) detection module connected to the USB TYPE-C interface supports three modes: DFP (Down-stream Facing Port, downstream port), the mobile terminal can only be the master device; UFP (Up-stream Facing Port, upstream port ), the mobile terminal can only be used as a slave device; DRP (Dual Role Port, dual role port), the mobile terminal can be used as both a master device and a slave device. Normally, t...
