That would be a fun challenge: given access to all sensors except for the camera, write an app that creates fake camera data.
If Google worked on that, results could be fairly creepy for those who store their data in their cloud. They can probably infer what you look like from your photos (you’re the one appearing in selfies most), know what weather it is locally, know that you’re, for example, looking at the Eiffel Tower, and maybe even have a photo from 2 minutes ago made by another user from the same place.
I think Google certainly could make a fake address book that’s creepy for many users by looking at the address books they have.
