Samsung has delivered on an earlier teaser with the launch of the ISOCELL JN1 camera for mobile devices today (June 10, 2021). It packs the industry's smallest pixel size of 0.64 microns, which fits in well with its relatively tiny overall size. The OEM asserts that it is ready to become the main, wide, ultra-wide or telephoto camera of the mid-range to flagship phones of the immediate future.
