So today I was in the living room with no one around or other noise, and was talking on the phone laying on my side and just having the phone lay on top of my ear. When the conversation stopped and the person on the other end hung up, I noticed that there was some very faint buzzing noises coming from what appears to be the inside of the phone.
I did some experimenting and found that when my phone is on, there is a buzzing/humming noise that's really only audible from the earpiece speaker. The closest thing I could compare the sound to is a hard drive reading or writing data. Right after turning the screen off, the buzzing/humming changes to a higher-pitched crackling that has alternations (like some computers where you plug headphones in and can hear buzzing whenever you move the mouse or do something). About 5-10 seconds with the screen of it turns to a solid high-frequency whine (like what you get with some USB wall charger bricks, but actually more comparable to something like the tire squeal of a car doing a burnout).
Has anybody ever witnessed this? These are quite high-frequency and VERY faint sounds so some people might have it but not be able to hear it with their ears themselves, but it's just something that I noticed.
