I had brought a Mibox 3 a month ago and after going through this sub and seeing people complain about how Oreo ruined their boxes i decided against making the jump from Marshmallow to Oreo. Albeit, the update had already downloaded itself in the background, i refrained from clicking the restart button but yesterday the box decided that it had enough of the BS and forcibly updated to Oreo. I was nervous about what the update would do to my box but fortunately, i am yet to encounter a single bug. In fact, the problems i had on Marshmallow seems to have gone. I am pretty happy with the new interface and now i wish i had not waited this long to update it. Also, i made a factory reset after the update.
Welcome to the silent majority.
