A:Answer Yes. The speakerphone button is on the call screen, lower left. If you are familiar with the Phoenix 3, it is in the same spot, but the screen looks a little different. The Phoenix 4 screen is a solid color (green). I am attaching the ATT link about the speakerphone with pictures . You should be able to view the manual on ATT or LG's site and you should be able to view a video on either site or on YouTube. ATT has some video tutorials on YouTube. Hope this helps.
