ISSUE 71 • ANDROID ADVISOR 17front – in part thanks to the decision to preserve the
front screen’s aspect ratio rather than fill out to the
sides, as on the Vivo NEX Dual Display earlier this year.
It’s still a very usable size, but only in brief bursts – any
longer than 30 seconds and you’ll probably just want
to switch back to the main display anyway.
The Z20 is available in either blue or black finishes,
and as you can see one of its best tricks is that the
secondary screen blends into the body – even with
the blue model – making it tricky to even tell there’s
a screen there if it isn’t turned on.
It does mean that my blue model has a slight tint
to rear panel that takes getting used to – not helped
by the decision to leave the blue light eye protection
mode on by default, so I spent a few days wondering
why the rear panel looked quite so yellow until I
realized I could turn that off.A separate 5.1in screen
