Samsung has unveiled the Z2 smartphone in India, the third in its Tizen OS-powered series and the first to support 4G connectivity, at an unveiling event.
The phones will go on sale August 29, priced at 4,590 rupees, and will be available in gold, black, and red.
The Z2 is powered by a 1.5GHz quad-core processor, 1GB RAM, 8GB internal memory, and a 1,500 mAh battery.
Samsung launched its first Tizen-running Z1 smartphone last year in January.
The spec-upped second in the series, the 5-inch Z3, launched in October the same year.
The South Korean tech giant said the third model was called Z2, rather than Z4, because it was a downsized 4-inch smartphone with less powerful specs than its predecessor.
Samsung is expanding Tizen application outside of smartphones. Last year it started pre-installing them on its TVs and applied it to signage this year.
