I bought 4gb 64gb version in the second sale.it takes three days to reach me.i am very satisfied with the look, it is awsome.the touch is good and the fingerprint senaor works very fast.i love the phone because for the 4gb and 64gb combination.the phone fast enough to operate and 64gb is enough memory so there’s no need of micro sd card.the battery backup is superb, you can easily excess the phone whole the day then also some percentage would be left.i used 7 hours with turning the hotspot on.the mobile does not heats up.the processer snapdragon 625 work very fine.overall it was a clever buy for me and I am very mich satisfied with the product.thank you mi for the beautiful phone.
