Hey everyone. I recently purchased a galaxy s8 edge 64g sm-g955n by mistake. I thought I was getting the US phone. I finally get the phone, turn it on and absolutely nothing is the same. I don't have any of the same menu options, it is only showing 2g of storage total, and it is running lollipops. It is the same outside as the s8 with fingerprint sensor and all but I can't use it because I have no menu options or anything. I don't have any security (fingerprint, iris, face recognition.) I can't customize anything but the wallpaper. What can I do to get all the features of a real s8?
