I recently noticed the earpiece speaker buzzes when I'm listening to a caller. It's not constant. It happens when the caller's voice is at or above particular volume levels, and only for certain kinds of sounds. It's like when you have the stereo up and only certain parts of a song cause items in the room (stove, fireplace poker set, windows, etc) to buzz because of vibrations.
The volume of the buzzing is proportional to the earpiece volume -- more if it's turned all the way up, softer if it's way down, but it doesn't go away. It doesn't sound like a blown speaker, I'm very familiar with this from working in home and car audio for a long time. It sounds more like the speaker is resonating against something. I'm thinking it's probably either a piece of sand that has fallen through the aluminum screen bezel and is just sitting on the earpiece speaker, or maybe there's a wire behind it that has come loose and is touching it. I noticed the buzzing sound seems localized to the side of the aluminum screen where the LED is so I'm also wondering it maybe the LED has come loose or is vibrating.
I bought the phone on eBay, so dealing with Verizon isn't an option. I'd rather do it myself anyway.
I want to take it apart and check it out. Does anybody have experience with this? Is there a high probability that I will break the hell out of it? It seems like I'd have to pop the back off, remove the 6 torx screws, and there's probably a 7th under a little 'void' sticker, then pop the body out from the front part -- hopefully this isn't too hard. From there, I'm not sure, but I'd guess I can then inspect the earpiece, hold it down and see if it still buzzes, etc.
Special tools? Gotchas? whatever-you-do-don't-remove-XXX?
Thanks!
