Really it's that loud to hear it when you just pick it up. Film videoThis is going to be interesting.
My first 7+ had the noise once with the camera app open. I tried to reproduce it again later but couldn't, not even with other apps like speedtest and geekbench. Unfortunately that phone had a scratched screen out of the box so was exchanged.
Current phone has noise almost constantly. I have raise to wake enabled, lifting the phone to light up the screen, nothing. Press the home button (not even unlocking the phone, just pressing it) and the noise starts.
If they release a software fix that works, then great, but hopefully it's not at the expense of performance.
