Some had some doubts online if MyPhone's only Android One device Uno will have the latest Marshmallow OS update (it's competitior already had one) until I confirmed it thanks to one Facebook user.
Thru the screenshots of Mark Santiago Cuyugan, he bought the said device at Lazada Philippines which at that time was at bargain price of Php 2,499. After that, he got a notification that it will have a Marshmallow update which has over 445 MB of size. These screenshots will tell that the update is now here.
As a friendly reminder, I recommend to have a stable and strong WiFi connection and enough battery for you to update your own MyPhone Uno smoothly.
