A method for improving fault tolerance of a touchscreen determines an abnormal node, and shield the abnormal node to improve the fault tolerance of the touchscreen. The method includes detecting a capacitance value of each node in the touchscreen, comparing the detected capacitance value of each node with a preset capacitance value of each node to determine N target nodes, where N is an integer greater than or equal to zero, and the target nodes are nodes whose capacitance values vary, determining whether an abnormal node is included in the N target nodes, where the abnormal node is a target node determined when no touch operation occurs on the touchscreen, and discarding a row value, a column value, and a capacitance variation value of the abnormal node when the abnormal node is included in the N target nodes.

A method and an electronic device for determining headset line sequence are disclosed in this application, where a third pin and a fourth pin on a headset plug are connected to a direct-current power supply to form a power supply branch, and a bias resistor is connected onto the power supply branch in series. This application obtains a second voltage between the third pin and the fourth pin, compares the second voltage with a preset first threshold, and according to a comparison result, determines a signal type of a signal transmitted by the third pin and a signal type of a signal transmitted by the fourth pin.
