Great find! However, I do not believe any of the current phones are related to UTOP. They are already selling all the models on the website. The phones do look very similar to the picture from CES though (Maybe same manufacturer).
Check out Maysun another Chinese manufacturer that seems to be interlinked with Shenzhen who seems to be tied into Huawei it gets confusing considering Shenzhen is a providence or city where mass manufacturing of many cell phones takes place including clones of pop brands . Same price point as Uhans
