Putting the speaker on the back of the phone is a major design flaw on Samsung's part and I'm surprised that they continue to roll out new phones without adjusting the speaker location. Not to mention that the volume and quality of the speaker isn't very good. I guess that it's something that most people overlook because all of the other positives of the phone outweigh this 1 negative (myself included). Laying your phone face down helps, since it points the speaker up towards you, but this doesn't do any good if you're trying to talk and use the phone at the same time. As suggested, search for a small, portable bluetooth speaker. There's no shortage of them on amazon. You could also pick up a bluetooth earpiece, which would be much easier to carry around with you. This also allows you to keep your conversations private rather than broadcasting through a speaker (if that's important to you).
