Why isn't my earpiece working while charging?

Earpiece not working while charging

Speakerphone works though, but when I turn it off I can't hear anything through the phone's earpiece. Only happens while plugged in. Anyone else having this issue?

Re: Earpiece not working while charging

I have the exact same issue. I was stressing trying to figure it out and thinking about getting a replacement. Once I unplugged the charging cable, the earpiece worked once again. Is this a defect or by design? Anyone?
