Mi4i is best mobile ever in these years. Bettry lufe of mobile is good but it has a little hanging problem. Look is good. Very slim phone.sound quality is best. Not supported external memory is big issue in this generation. Camera quality is good. Tjis is little extra ordinary phone in market because of its many things. I love this phone because of its thikness. Its not Xiaomi Mi4i. Its Xiaomi My4i.
