The Xiaomi Mi Mix 3 should soon be released officially in France. In the meantime, MIUI 10 is available in "Global" version on the device for those who have imported and the most impatient.
Xiaomi's products are unique, since they really stem from the desire to popularize MIUI, the alternative ROM created by the foundation. It is always available in two versions: Chinese, and "global" for other markets.
While the Xiaomi Mi Mix 3 was introduced a while ago, but we are still waiting for its European release we were promised "about two months later"; the time to develop the global version, just stupidly.
Today, XDA Developers has spotted its release. As a reminder, it comes preinstalled with the Play Store and Google services, does not integrate the many services exclusive to China and is translated into various languages (including French). You can download it directly via the official MIUI website.
Attention: the installation is not an easy task, look at the question only if you are already a regular flash on Android. For others, it will be enough to wait a little bit: the announcement of the European release of Mi Mix 3 should not be long now that the Global ROM is available.
