For reference, the initial Note 7 "overheating" issue started out as 1 in 40,000 devices. As more devices caught fire the ratio dropped down to 1 in 10,000 which was bad enough for Samsung to issue a full recall and cease production. So yeah, 4 devices so far out of a very small number of review units is pretty bad.
I appreciate your post, but it really doesn’t answer the questioned I posed earlier, like how many devices are actually out there in total they been manufactured that experienced this issue? You’re merely mudslinging based off what four devices experienced, but Nor does it address The magnitude of XYZ units produced. That said, it doesn’t take away that Samsung has a product that has a quality control issue either. The reality is, there’s two things that are not mutually exclusive in your post, a hardware defect with a device like the Galaxy fold and then a potential safety hazard with the Note 7.
