Update to fix vibration notification bug in Pokemon Go's Nearby feature is on the way5
After being removed from the game, Niantic now says that Nearby can now be found "in most regions of the world." In a separate issue apart from the buggy vibrations feature, not everyone is happy that the latest version of Nearby will find Pokemon only near PokeStops. Niantic has arranged things so that those that live far from a PokeStop can use the Sightings feature to see which Pokemon are close by.
The next big update is supposed to take place on December 12th. 100 new Pokemon are being added to the game along with some of the legendary persuasion. Players will be allowed to trade Pokemon and the eagerly awaited Player vs. Player battles will commence. In addition, over 10,500 Sprint, Boost Mobile, and Sprint at RadioShack locations will become PokeStops on December 12th.
