According to Chinese website myDrives, the new Mi3S will have a design enhanced with “more metal.” Its specs will be improved as well, reportedly including a quad-core Qualcomm Snapdragon 801 processor, 3GB of RAM, LTE connectivity, an 8MP front-facing camera, and a 13MP rear camera. The handset’s display seems to be similar to the screen of the Mi3: a 5-inch, 1080p panel.
It’s said that Xiaomi will sell the Mi3S for $320 (1,999 CNY). There’s no word on exactly when the handset will be released. However, as it happened with the Mi3, the new Mi3S should be available in China first. Since Xiaomi started selling handsets in more Asian markets recently, the Mi3S will probably not be a China-exclusive device. But we'll see what happens.
