Export a screen play to read a role on a smartphone?

Is there a way to export a screen play to a file so that it is possible to usefully use a smartphone instead of a printed version for the actors to read the roles (without scrolling horizontally)?

I could not find a way to read a role (without the other text) in a screen play (e.g. during rehearsals) on an Android smartphone without horizontally scrolling (so a line break would be needed for the lines of the role(s)) all the time or too small fonts without scrolling (and displaying the entire line). Or losing the entire text formatting.
