Me trying to comment on this article from my Meizu 5 Pro Ubuntu Edition using the only browser available for the OS. (https://imgur.com/NbWYNj5) Ubuntu Touch should be called a beta and -considering in how many ways it differs from the desktop version- maybe it shouldn't be called Ubuntu.
The Meizu MX5 successor will reportedly come in both Android And Ubuntu SKUs with the Helio X20 SoC. Other core specifications like screen size remain unknown.
