Many people around the world buy smartphones with MIUI7, like the Xiaomi Redmi Note 3, but later, they complain about the chinese/english stock ROM, so they can't use an official version with his/her native language. Installing a custom ROM in a new phone often ends up with a bricked phone. Also, the most of the custom ROMs aren't stable, and don't get updated often. We think that you could make a small effort and add more languages. Thank you.
