Hi guys, I've started hearing a high pitched noise every time the screen (backlight) is on. It's not super loud (I only hear it when the phone is about 3" from my ear) and sounds similar to "ringing" in the ears.
When I place the phone in sleep mode or if I am on a call with the proximity sensor activated I cannot hear anything.
I've done a battery pull, hard reset, and even reset the phone back to its original firmware via backup. Has anybody else experienced this? Is this within the normal operating parameters?
Thanks!
