The Samsung Z, which will be the first smartphone to run Samsung’s homegrown Tizen operating system, has suffered another setback. The device was supposed to be launched first in Russia in conjunction, with a Tizen developer’s conference taking place in Moscow. However, no device has been launched, and Samsung told the Wall Street Journal that “the smartphone will appear on the Russian market later, when we can offer our users a [sic] fullest portfolio of applications.” Earlier this year, a device running Tizen was supposed be released in Japan, but the launch was canned after carriers pulled out.Related research and analysis from Gigaom Research:Subscriber content.
