So how does it work? Thinking about it, we can say that the filters for each city are only unlocked when we are in that city, so logically by changing our GPS position to make our phone believe that we are in a certain city, the application will give us access to the desired filters.
Before saying more about this tip, know that a new method much simpler and faster to carry out is available at this link.
There are special filters for almost all major cities in the world but also exclusive ones for popular places and neighborhoods, so it is possible to have filters specific to new York in the district of Manhattan which are different from those found when one is at Central Park, same near the One World Trade Center or even of theEmpire State Building.
Consider restarting totally the application as shown in the video if the filters do not appear immediately after taking a photo. If even after following all the steps in the video you still do not have the filters for the desired city, it is probably because there are none notin this one.
It is true that it is not a better solution to wander around a map to find filters that we like because we do not necessarily know the location of all the Snapchat filters. This is why, as said above, a new trick has been found and allows us to precisely obtain the filters of our choice by having the choice among all the existing places that offer them with a simple click, without bothering to choose and emulate a place.
However, if you still want to follow this tip, you will only need the app Fake FPS Location which is available for download in the required items area further down this page.
