Instructions for Pokémon Go:
1) Set the fake location on the app (you'll be asked to enable mock locations first every time, do it)
2) Once the fake location is set, go back to developer settings on your device and disable mock locations (you can find a shortcut inside Location Cheater settings section)
3) Open the game, the character should be moving to the location and poke stops must be visible.

Alter your geographic location on:
-Facebook
-Instagram
-WhatsApp
-Google Maps
-Badoo
-Happn
-Grindr
