How can i have different point spot style on mobile devices?

Hi,
Is anybody know how can i have different point spot style on mobile devices ?
I am currently using Concentric circles - Neutral (Sequence) as my point spot style but is not pretty clear for the viewer who see the tour on mobile devices so if i could keep my current spot style for PC but use other shape like arrow for mobile devices would be amazing.
I really appreciate your help to resolve my problem.
