At max volume the speakerphone is fine but at any volume the earpiece buzzes when someone speaks (the louder the buzzier of course) So definitely defective or something that will break in? Basically it's the same effect as having a blown speaker. Noticed it the very first time I used the phone. That's the rule right? "If an electronic is going to break, it will break right away" My i4 doesn't have that problem and never did.
