Unistar recently introduced the newest installment in its X series, the Unistar X55.
The X55’s design is pretty similar to the X7 with its curvy and pointy edges although the former is bigger. Its measurements are 150.9 x 76.6 x 9.5 mm and it is available in brown, white, and blue.
The X55 uses an octa-core LTE processor, the MT6592, and the MT6290. It supports WCDMA, FDD-LTE, and GSM. It sports a 5.5-inch display screen with HD resolution and uses OGS technology. It also has a 5mp/13mp dual HD camera. Its memory is not that great however, having only 1GB RAM and 4GB internal memory space. It runs on a 2500ma battery and its operating system is the Android 4.42.
Like the X7, the Unistar X55 will probably be released overseas first before it gets released in China. [source]
