Does have Xiaomi MI3 Gorilla Glass? Are there any sample images of its camera, is good as iPhones 5S camera? Which CPU has the best power consumption Snapdragon or Tegra4? Where can I buy this phone in best price possible? Is build quality of this phone good? What MIUI does more , or why is better than Androids default launcher? Will this Phone get Google KitKat Android, and later Android 5? If a part of the phone breaks , where can I buy only the part? Sorry for these all questions.
