As of today 9/13/16 I am still waiting for Pokémon Go update 0.37.0 for my Android device and nothing yet. Over the weekend some reports that users had already received the new update including the “buddy” system, but most of my friends and people I have talked to, have not yet received any update, not sure what are the requirements and if its only at certain markets. With the Pokémon Go Plus device coming in 3 days, people will want to get the update ASAP to be able to start collecting candy and items.
Some people may not know what the “buddy” system is all about, and well since last time I posted I found more information. The “buddy” system will allow you to select one Pokémon to be your companion, depending on the size and if it flies or not, you will see that Pokémon next to your profile screen either besides, on your shoulder or flying behind you. Whichever Pokémon you choose after several km walked you will gain candies, and items, from what I read each 1KM will be 1 candy, so expect a lot of walking for those rare to find Pokémon, or for those that hatched from an egg.
Below is the patch notes from Ninatics for the new 0.37.0 for Android and 1.7.0 fir iOS:
Pokémon GO is in the process of being updated to version 0.37.0 for Android and 1.7.0 for iOS devices. Below are some release notes and comments from our development team.
Implemented Buddy Pokémon: Trainers will now be able to choose one of their Pokémon to be their buddy. A Trainer can earn Candy for their Buddy Pokémon by walking a certain distance.
Made it easier to select smaller Pokémon on the screen.
Fixed an issue where Eggs would sometimes hatch without displaying the animation.
Improved performance reliability when a device switches networks to no longer cause the application to hang or stop updating.
Pokémon GO Plus support
Minor text fixes.
We continue to focus on eliminating bots and scrapers from Pokémon GO. Rooted or jailbroken devices are not supported by Pokémon GO. Remember to download Pokémon GO from the official Google Play Store or iTunes App Store only./ Source
With that said, I hope I get the update soon to start collecting candy and see what all this update is about, and hope new options like trade which we been hoping for a while, comes soon along with newer Pokémon.
