A few of us were joking about poisoning the location tracking database of site along a similar vein. Have an app masking your location to some place in the pacific ocean to any app running in the background asking for location (without the user's intent of using it).

Why stop there? Create a service that will spoof GPS coordinates, check you in, and post generic photos of fun places to be, so you can outsource your social bragging through automation.

On Android, Xprivacy uses hooks provided by Xposed to "MitM" a lot of functiom calls. Don't want an app to know your phone's serial number? That function call returns a spoofed one. Same with GPS location.

I love Xposed. I just wish using it didn't mean I couldn't get regular Android updates (I have a 5x).

You can certainly do that with a jailbreak.
