Right now vote counts are not shown on the mobile theme.
I read from an old post show vote count on the mobile theme, that is was because some old mobile browsers were too inaccurate.
An answer to that post says:
The gotcha is that a lot of android phones really don't have the click accuracy you need to distinguish between up vote, down vote, and show vote split clicks. It's really quite frustrating trying to vote and accidentally displaying votes or vice versus.
Since it's such low priority information, I pulled it. We might revisit this when the balance of android browsers shifts, I hear through the grape vine it's gotten a lot better in the latest and greatest versions. Still too many old ones out there right now though.
That was written in 2011 and now we’re almost in 2020. Does this still apply?
It would be cool to have that feature on the phone.
