Jolla, on the other hand, was a company trying to create an entirely new OS (as well as an entirely new revenue system), and only started the tablet as an afterthought (and at a point where the company's finances were already looking iffy).

Unaos appears to be offering Yet Another Android flavor on Yet Another Android-based Phone (a phone built by LG in this case). I can't imagine this being anywhere near as hard to pull off as what Jolla was doing...
