One of the Galaxy S8's standout features is Samsung's Bixby assistant. It not only organizes your schedule and talks to you, but also helps translate and identify items around you via the phone's camera. It even talks to your SmartThings-compatible home appliances, and can quickly be summoned with a dedicated physical button on the S8's left edge. But if you don't plan on using Bixby very much, that piece of hardware becomes mostly redundant. Luckily for you rebels, the internet's inventive community has found a way to assign that physical button to any app you wish.
