A few months ago I was desperate with my old phone Huawei G700 with Android 4.2 that did not work well with the old firmware of the manufacturer. Searching the internet I found a Russian firmware MIUI for this old smartphone with Android 4.4 that surprised me by its excellent quality. For this reason I have decided to buy a new smartphone of the brand Xiaomi, it is the new Mi Max 2 without knowing the problems that would have. The experience has been very good. I bought the smartphone in a Chinese store with warehouse in Europe. I have not had any issues with setting up a Spanish language or accessing the Google Play Store, and everything works fine. Hardware / firmware details: - American charger with adapter to the European electrical network. - MIUI Version: MIUI Global 220.127.116.11 (NDDMIED) - Bootloader: unlocked - 4G LTE works well with Orange Spain in the B03 band (1800 MHz). According to the technical characteristics this smartphone does not work in the band B20 (800 MHz). I will wait at least a year to find a solution, I do not want to do it now with the new phone that works very well In short, for me it has been an excellent purchase.
