Im on a GS3 with the latest firmware and my two friends are both using iPhones. When in a group message, I will try to send a text and I will often get the error "Message Not Sent" and after multiple re-trys it will finally send. Sometimes I need to delete the failed message and retype the entire thing in order for it to send. Also, when one of the two iPhone users text, I will often get a blank message from an unknown sender in my inbox instead of the text in the group message. The other people get the text, just not me. They are not using iMessage either. I am due for a new phone within the next two months as this one is starting to get laggy and buggy, but until then, I'd like to know if theres a fix for this issue. Thanks.
