Abstract
A method for protecting a touch-sensitive device includes: switching the touch-sensitive device from a normal mode to a protection mode when a preset operation is exerted; determining whether a touch operation is exerted after the touch-sensitive device enters the protection mode, and further determine whether a duration of the touch-sensitive device in the protection mode exceeds a preset time interval; comparing a touch size of the touch operation with a preset size when the duration of the touch-sensitive device in the protection mode exceeds the preset time interval; and generating an alarm signal when the touch size is less than the preset size. A related touch-sensitive device is also provided.
