video on smartphone


I have a video shot in vertical mode on youtube. I used H5P to add interactivity. On the pc is great but on smartphone I have a very small video, whatever the orientation of the smartphone ....
Is it possible to have a full-screen vertical video on the smartphone?
Thank you for your help.
