As an answer: They are used for listening audio in portrait orientation ;)
and to contribute into the discussion: I agree they could have been placed much better, as additional to the orientation, the audio is now directed away from the user. Additionally, when device is laying down on table, they are against the table... In which case the device needs a stand / something under it.
I hope Jolla picks a better speaker placement for possible future models, following the principles of Finnish Design on which the usability is often in a key position. For example having three speakers in corners, selecting left/right channels for each by the orientation of the device, would have been something unlike and also something nobody else has yet.
