Most of the Samsung phones on the market come with a speakerphone feature that allows you to broadcast your phone calls to wider range. This is ideal when you need more than one person to hear the call or if you aren't able to hold the phone to your ear. While there are many Samsung phones on the market and it's possible they each have their own settings, most allow you to set the speakerphone from the call menu.
Click the dialpad icon and dial the number you want to call.
Locate the speakerphone icon at the bottom of the screen. It looks like a side view of a stereo speaker.
Click the speakerphone icon once to enable the speakerphone feature. Click it again to turn it off.
