The smartphone was introduced in 2014 and turned out really good - a five-inch Super AMOLED screen with a FullHD resolution, 8-nuclear MT6592 Turbo (2 GHz), a beautiful design and the official price of $ 200. Rebirth failed, and soon the world saw a series of smartphones UMI: EMax, EMax Mini, Fair, Hammer, Hammer S, Iron, Iron Pro, Rome, Rome X, UMi Touch, UMi Touch 2, UMi Touch X. Preparing to start selling the much-touted flagship UMI Super, which, though a bit disappointing performance and price balance. Also not spared our brand and fashion virtual reality. UMI promise to release the headset VR Box 3, which will work with any smartphone. Source: http://mobilephone-manualsonline.jimdo.com/umi/
