I recently received a replacement Galaxy S6 because my screen broke and is totally black (thank goodness for insurance). Two questions: 1. I had not saved my photos to the sim card or the cloud (I know, bad), so is there any way to retrieve them? 2. When I tried to download a theme onto the "new" phone, I am asked for my Samsung account; I don't think I have one, but I also cannot seem to create one?! Thanks for any help provided.
