Redmi 4 is very worst product. I have brought the mobile on april 2018. Two to 3 months the phone shows a average performance.After that once i switch off the mobile then it would not get on. Then i visit MI service center they said that the charge boards shroud be a problem we would change free of cost shinwari period after changing the board it works around 10 days after that the same issues was happened again.Redmi 4 have very poor build quality .it gives me high level of disappoinment.i lost my money.
