In addition to making full frame sensors for Panasonic (?) and coming back with their own new mirrorless camera (?), Samsung is apparently now also making APS-C sensors for... Fujifilm and also Ricoh/Pentax... The source? A random comment made by somebody on a forum. Then another forum referenced the first forum, then another website quoted two sources, then a desperate rumors website quoted 3 sources... and so on, you get the idea.
While there is some evidence that Samsung and Fujifilm/Pentax are/have worked together, I just would like to remind you of some of the fake/made up Samsung/Fuji rumors reported in the past few years:
No, Samsung is not going to resurrect their NX mirrorless cameras
Nikon: the Samsung deal was a “hoax”, there was never even a talk about it
