What happens?
the two screens in google cardboard view are to far apart, the x shift option doesn't seem to do anything.
and the screen size option does not cover 100% of the screen horizontally when set to 100%
What should happen?
if the distance between the two screens can be adjusted, larger phones could also use the cardboard option
What hardware : xiaomi note 8t
