Common wisdom in digital photography says that megapixels aren’t everything. They matter to an extent, but smartphone makers have a long history of leaning too heavily on those numbers as a kind of shorthand for camera quality. In other words, they play an important role but need to work in concert with a number of other key elements to truly deliver on their promise.

The good news here for the upcoming Galaxy S23 Ultra is that Samsung’s got a solid track record of building camera ecosystems on both the hardware and software fronts. In fact, the company actually made the 200-megapixel system that appeared in Xiaomi’s 12T Pro flagship toward the end of last year. The company wouldn’t confirm whether the S23 Ultra utilizes the same chip (only saying, unhelpfully, that they’re calling it a “200MP Adaptive Pixel sensor”), but I’d say that if it’s not 1-to1, it’s likely very, very close.
