Lots of random sources seem to think some upcoming iteration of the iPhone X will feature three rear-facing cameras, either this year or next. So here we are: I’m telling you about these rumors, although I’m not convinced this is going to happen.

The most recent report comes from The Korea Herald, which claims that both Samsung’s Galaxy S10 and a new iPhone X Plus will feature three camera lenses. It isn’t clear what the third sensor would do exactly for Apple. Huawei incorporated three cameras into its P20 Pro — a 40-megapixel main camera, a 20-megapixel monochrome camera, and an 8-megapixel telephoto camera. Most outlets seem to think Apple’s third lens would be used for an enhanced zoom.
