When i recieve a text from my brother, and I got to reply, it changes his number in the texting menu from (XXX)XXX-XXXX to +1XXX XXX-XXXX . This makes the number bad, because it tries to send to "+1XXXXXXXXXX". So I have to delete the conversation thread, delete his contact, and write a new text to him by manually typing the number in every time.
Any idea what is happening???
