Friends do not BUY REDMI phones, they sale worst phones. I bought MI 4A in April 2017 and it was in good working condition, but after some days I realize the problems with its music player and till date phone is in the service center. They have taken one week to detect problems and now they do not have a solution so they want me to stay calm till problem solve. Althogh, I have done many emails to Xiaomi service support team, but they are not helping me in any way. Its up to you friends, but this is my problem and I dont wish it happens with you
So best.
