Even J7 2016 now has Samsung Experience 8.1 which means the same User interface like S8 or S8+. Why don't we S7 Edge users are not getting it? or will we be getting it? if yes then when ??

Battery drains faster then before after August Security Patch. Also it's even getting overheated. I confirmed this after I heard from more than 10 to 15 friends who also uses S7E and also updated to August Security Patch.
