Friends do not buy redmi phones, they sell worst phones. I baought MI 4A in april 2017 and it was good in working codition, but after some days I realize the problems with its music player and till date phone is in service center. Theyhave taken one week to detect the problems and now they do not have a solution so they want me to stay calm till problem solvs. I have send many emails to xiaomi service support team, but they are not helping me in any way.
