Hi, friends six months ago I bought new mobile that is redmi 4. I purchased it from amazon.com by seeing this mobile at first time it looks very gentle and smoth surface. Little bit it looks like iphone.There is gorrilla glass. Back side metal.i got it in black colour there is white colour also.but I like black.Performance is very good.But the bad thing of this phone is that it bends easily. In my phone there are 2 dents and one bend near the fingerprint scanner.The fingerprint scanner is very fast responsive.My favourite feature of this phone is the way of taking screenshot by using 3 fingers. You have to just slide 3 fingers on screen.At the last, I want to tell you all that in this price range Redmi 4 16gb is the best mobile phone.
