I would like to know how to send a new text message without it being attached to previous messages. I don't want to delete the previous messages, just start fresh without all the others being attached.
Android phones keep messages between two parties (you and the other person) grouped in a conversation list. I don't believe it is possible to change how the messages are displayed in the stock text message application. You might want to check out the third party applications for that option to separate the conversations.
