I'm looking for reliable feedbacks from actual users of the Mi4 running latest w10m preview builds because I'm weighing my option between that unit and going for 930. I am currently using 640 LTE, really want a 950 but that's not in my budget range at all, besides I can only afford upgrading to a second hand unit anyway and here in our country they are almost at the same price (2nd hand). My eye is currently at the Mi4 because it's a bit cheaper and with a better specs than 930 so I would really want to have honest user feedbacks first. Thanks!
