The global version of the Xiaomi 12X comes with two key differences compared to the Chinese one: 8 GB maximum RAM and slightly lower maximum brightness on the AMOLED display. These downgrades certainly do not hinder the performance of the Snapdragon 870 SoC that is still one of the best processors at this price point. Also included is the latest MIUI 13 OS based on Android 12.

not mentioning the fact that this phone launches on a pathetic android 11 instead of android 12 AND only gets two updates unlike the xiaomi 12 and 12 pro is a complete fail. Phone is cheeks
