The Galaxy Note 8 is Samsung's first phone to boast dual rear cameras, and it seems like the company may fully embrace the two-camera trend going forward. Rumors are circulating that devices like the next Galaxy S flagship and the mid-range Galaxy J7+ may get a dual-camera setup.

Dual-camera phones have become more popular over the past few years. They've appeared on both premium flagships (like the iPhone 7 Plus) and budget friendly phones (Huawei Honor 8). But Samsung -- a major player in the smartphone industry -- didn't make any dual-camera phones until it unveiled the Note 8 on Wednesday.
