I have a new Samsung Galaxy S III and noticed right off in Messaging that when I receive an email sent to multiple recipients, the default tab for response is Group conversation. I changed it to default to Individual messages because my preference is to reply only to the sender. However, I was surprised to learn that my individual messages are being received by all who received the initial group chat. This was not the case with my Charge and I can't find any corrective action I can take to prevent it and it is very annoying. Thanks for sharing similar experiences, especially if you have figured out how to fix it.
