All the films has only one (two in Covenant) androids, so what about a crew where the falf part of even more are androids? Like 6 androids 3 humans. The humans are like, we can't risk our lives, if the xeno capture us there will be another one and we will absoloutly die. So they start sacrifacing the androids to survive but finally the androids face the humans because they are intelligent and obviously they don't want to die. So at the half part of the film que have 3 teams: humans, xeno, androids.
