When I am making a phone call. I can hear the same sort of noise you notice when you are making a phone call next to a speaker system. It doesn't happen all the time so it must depend upon certain factors including what network mode it's using. It doesn't actually appear to be coming from the earpiece but rather the back of the phone (near where the camera is) as I can hear it more clearly on that side plus also when I'm not in a call.
The noise actually does change depending on what I'm doing. For example, sometimes I will hear a clicking noise just when I'm browsing the web (although this is a non issue, I can only notice it in a quiet room)
So yeah, do you think I should RMA the phone over this? Do any of you guys have the same issue? Thanks.
