Abstract

A method comprising: receiving, by an electronic device, a first signal having a first frequency; identifying, by the electronic device, at least one of a strength of the first signal or a signal-to-noise ratio of the first signal; outputting, by the electronic device, a second signal having a second frequency that is different from the first frequency, the second signal being output based on at least one of the strength of the first signal or the signal-to-noise ratio of the first signal; receiving the second signal by the electronic device; and detecting whether the electronic device is at least partially immersed in a liquid based on the received second signal.
