I got my old Samsung Galaxy Core Prime G360 when we went with Verizon years ago. That phone began having an issue. So I bought through ebay the same phone -- Samsung Galaxy Core Prime G360. On the original phone I had Message+ for texting [red icon with two chatboxes on it]. What I have on the new phone just says "Messaging" [with a white envelope, with a yellow message sticking up]. Yet, I don't even see this "Messaging" when I click Application Manager. Is there a way to get Message+ or some equivalent on this phone?
