Last week, Niantic announced that they're taking the fun of Pokémon GO's AR+ feature and making it far more accessible. With the new and improved GO Snapshot feature, you'll be able to grab cute pictures of your favorite Pokémon any time you want instead of just when encountering wild creatures on the overworld.
If you're an Android user, you can try it out now! GO Snapshot is currently available to all Android players at level 5 or higher. It's unclear if that's a permanent requirement, but it takes very little time to reach level 5, so it shouldn't be too much of a hurdle. If you're playing on something other than Android, Niantic says you should "stay tuned," so you shouldn't have to wait too long.
