As first reported by Android Police, owners noticed a clicking noise coming from the phone that sounds like the tick-tock of a second hand on an analog watch. Several people noted that when they turned NFC off, the clicking sound went away.
The high-pitched sound seems to be an unrelated issue without a specific solution.
