Next up: cameras. Both motherboards have to come out first.

These two camera arrays differ mainly in how they zoom, and how many pixels they pack:

The Ultra inherits the super-cool optical Space Zoom module from the S20 Ultra, but with a smaller 12 MP sensor behind it. (Click the link for a detailed take-apart of the periscope mechanism.) The regular Note 20 doesn't "space zoom," instead relying on a dense 64 MP sensor and some cropping magic.

The situation reverses for the wide-angle module, where the Ultra gets a gigantic 108 MP sensor—which, like the S20 Ultra, usually bins down to 12 MP. Meanwhile, the regular Note packs a more modest 12 MP sensor here.

Neither Note gets the S20 Ultra's 40 MP front-facing camera—instead, both pack 10 MP selfie sensors, which appear to come bundled with some unfortunate smoothing effects.

Oddly, the standard Note 20 releases its selfie module with gentle prying—but the Ultra's comes firmly hot-glued in place.
