Facebook seems to be testing a new feature that allows you to identify Wi-Fi networks through the mobile social network application for iOS and Android.
Some lucky ones are seeing a new option that is found in the side menu of the application to find Wi-Fi and the same one uses of our local location to work.
If you tap the new "Find Wi-Fi" option automatically, the app requests permission to access your current location to work properly and find Wi-Fi networks near your area.
The new "find Wi-Fi" option requires that access to the mobile app's location be set to "Always" instead of "While using the app"; and to configure it you must go to Settings -> Privacy -> Location Services -> Facebook.
As you can see in the screenshot above, the new feature marks on a map any Wi-Fi connection available in your area. You can tap at some point for more details.
The downside of this is that you do not really know if the Wi-Fi is really free in places that bring the app, ie it is not certainly know if you must pay a drink to get the key and gain access to Wi-Fi for a trade, for example.
If you let Facebook always track your location, your location history is also triggered, something that can annoy more than one, if what concerns you a lot is privacy.
Finally, it should be noted that Facebook has gained notoriety in the past because of excessive battery consumption when the localization function is always active. We hope that Facebook has solved this problem so that its official application does not make a high consumption of the battery of our devices.
