Phone stolen.

I'm currently in Mexico on an AmEx 2-4-1 trip that gave me my first pair of Lufthansa ducks. Unfortunately, my Android phone was stolen today. While I've tried to block the phone remotely through Google, and while I think it unlikely that anybody would be able to access my data, I'm a bit concerned that somebody could in theory access the SAS app in my phone and request to cancel my return flight. Does anybody know if there's something that I could do directly with SAS to block that possibility?
