Xiaomi Devices And Lte Bands

Feb 11, 2014
This is not a question about Mi5 but all Xiaomi devices

I think Xiaomi is one of the best smartphones companies. Their devices, their support, their prices are the best in the market. But the lack of support in some LTE bands make a lot of people choose another brand.

My question es this:

Is too difficult to Xiaomi, to realese devices with support for another LTE bands than the chinese ones?
A fact is that the hardware can support all the bands. So is a sofware problem. Will be expensive to provide a tool to flash the phone and bring support for another bands? Why do you think Xiaomi do not work in this direction? I think they will sell a lot of devices arround the world.
