Re: my phone has a beep while on a call?

Welcome to Android Central! Which phone? How frequently does it beep, and for how long--the whole call? Is it beeping over the earpiece speaker, or the phone's main external speaker? Are you sure it isn't call waiting?

Like B. Diddy said, it could be call waiting or if it comes at 1-minute intervals, you might have activated the Minute-minder feature some phones have.
