I very rarely write reviews, but honestly I'm driven so mad by how utterly useless this app is, I felt the need to share! Everytime I go in to my inbox I can see mail, I can manage mail, but I cannot OPEN mails. I have to try to open them, then force the app closed, then try again. More often than not it tells me the app isn't responding! Not really good enough for the default mail app Samsung!!
