I be happy with Android 7.0 firmware on my Umi Super.
But believe that UMI should end Android 7.0 with a new update and maybe upload to 7.1, although I see this impossible because of the number of UMi models.
Go to the rom section of this forum and find a umi super 3.02 rom. Follow the guide there and when you are in the spft instead of "download only" use the option of " firmware upgrade". This will give you a android 6 rom.
Just read the whole thing and flash it if you feel confident about it.
@ your own risk of course.
