How do you operate speaker phone on Samsung r355c?

Answer 1

Hi i just got my Samsung r355c from straightalk ive been wondering how to do this aswell but i just figured out while talking to my girlfriend on the phone ok you have your standard phone with the send and end keys BUT right above send is a little silver button with what looks like a speaker and has a arrow pointing to the right press and hold that for atleast 2 seconds and it will enable speaker :) hope this helped
