Hissgate
This is a peculiar one and for the time being, there’s no available fix. Some (many? most?) iPhone 7 Plus units emit a barely audible hissing sound while in use. You can hear it if you place the Apple logo on the back of the phone to your ear and scroll down any screen. While the sound on most phones doesn’t appear to be loud enough to be audible at a reasonable distance, some users report that the hissing actually is much louder when the phone is under a heavy load.
