What's with the default messaging app....sometimes I'll send a text message, then 10 min later the warning sign comes on that it wasnt delivered, but in between that time I dont know if it wasnt delivered or not...on all my other phones when id send a text it would say "message" sent right after...showing it was sent. But now if I turn on notifications I get a text back saying my message was delivered but thats extremely annoying. Any fix?
