Samsung Z5 apparently spotted online
Samsung's Tizen platform has only been available on a few markets and the only two handsets running it are the Z1 and Z3. However, sale figures were good enough to make the Korean giant continue pushing resources into this new operating system and to develop another Z series handset.
According to a recently spotted cargo document, 310 units of an "ASSY METAL REAR UNIT" were imported to India for testing. Since the value of a SM-Z510FD unit mentioned by the shipping manifest is roughly $25 USD, most chances are that Samsung Z5 has a metal chassis and a cheap design that uses plastic. On the other hand, the description of the product also mentions "FOR MOBILE PHONE" so the units shipped from Vietnam might be incomplete prototypes as well.
Unfortunately, there are no solid details available for now, but since it is highly likely that Samsung Z5 is still in an early development stage, its first official appeareance must be at least a few months away.
