Need some help IDing my mango variety

[SsSamed]

They came from a mature tree in my backyard that was already there when I moved in to this house, picture is from 2 years ago since I didnt get any crop last year with funky weather. flavor is very sweet with no acid, and if I remember correctly there were fibers, but I could be wrong about that. Size is about 4-5 inches long maybe 2 inches wide, I dont know if size is reliable though as I haven't really took care of the tree and I'm only about 6 miles from the coast so it doesn't get super hot where I am.
