After Doing my researches on Chinese Forums about P8 Despite I don't read or talk Chinese
I Found Those lovely themes Ported For mate 7. As you see there is 6 Themes included.
Beside I did edit them to remove the stupid Black shadow Background for icons that aren't themed.
I think it will be included in Lollipop Update.
enjoy it :
