There are no such problems for Chinese rival Vivo, which has finally launched in Europe this week with the Vivo X51 - really a re-branded X50 Pro - and a trio of budget Y-series phones. Can it replicate the success of Xiaomi and Oppo in western Europe?

You can watch it all in the video embedded up above, or head straight to YouTube to watch it there (and subscribe if you fancy!).
