No MMS It backs up MMS  it doesn't restore it. Huge negative for me. SMS feature seems to work fine though. Only backs up in sets of 100 for me (even though I have it set to """"""""All""""""""). Haven't tried restoring SMS but atleast has the option. Also  not seeing anything like images or the vast amount if emojis supported on Android on Gmail. Not huge  but maybe important to some people.""
