Phone data collection seems to end too early

[shankari]

Consider the trip for user 0763de67-f61e-3f5d-90e7-518e69793954 from 2016-02-29T08:35:35 to 2016-02-29T08:50:11. We almost end the trip on the server, but not quite.

It looks like the trip fixed itself when we got the next set of points.

This is not ideal, because we only got the trip end when the next trip started.
But it is not a huge problem either.
