There was the Light L16, a bizarre camera that had 16 lenses (hence its name), although it had multiple lenses of only 3 focal lengths. The concept was that it'd use computational software to make high quality images of your desired focal length. It cost $65 million to develop and was a complete failure. Not because it didn't sell (well, yes actually) but because it didn't even work. It'd crash, fail, freeze, etc. If you happened to actually get photos, they looked lousy.

There's been a handful of "cameras with phones attached", notably from Samsung and Nokia. The Samsungs were Galaxy Androids. There's also been a number of phones that were designed to have camera modules attached that provide grip, shutter buttons, etc. The Xiaomi 15 Ultra is a current phone that was designed this way (and with Leica branding). There's been some kickstarter doohickeys and other kludged grips for existing phones, but these aren't quite that same idea.
