hi, I got a S7 edge. there is a freebook per month on Amazon. so I login into Amazon with the builtin app with my own Amazon account. I clicked the freebook and I was asked to create a Sumsung account and I did. after that, I logined with Samsung account, I was told that the account (samsung) is already existed. and it jumps back to the orginal Amazon pages with my own Amazon account. I deleted the Samsung account in the setting. then start again. still it will told me the same when I login'd in. is there anyone can help me on this? or is it because I'm not in US? thanks I like the phone but the phone app sucks. it's the only phone that separates contact list and groups into different app. I cannot search by group in phone app or search by name in the group app in the phone app. it's really inconvenient.
