How to Make a Conference Call on the Samsung Galaxy Note 3
If you are ever in situations where you would like to talk to more than one person at once, it is lucky for you that your Samsung Galaxy Note 3 has a conference call feature!
Unlike someone interrupting a conversation with an incoming call, a conference call is one that you set out to make intentionally: You place one call and then add a second call. Touch the Merge button in the Phone app, and then everyone is talking. Here's how it works:
Phone the first person.
After your phone connects and you complete a few pleasantries, touch the Add Call button.
The first person is put on hold.
Dial the second person.
You can use the keypad or choose the second person from the phone's address book or from a recent call found in the call log.
After you connect with the second person, the Galaxy Note touchscreen looks like it does when you're on two calls.
Touch the Merge button.
The two calls are now joined: The touchscreen says Conference Call. Everyone you've dialed can talk to, and hear, everyone else.
Touch the End Call button to end the conference call.
All calls are disconnected.
When several people are in a room and want to participate in a call, you can always put the phone in Speaker mode: Touch the Speaker button.
Apparently, you can add a fourth conversation to the mix, as shown by the enabled Add Call button. I've not tried this option to see whether it works.
