Hiii freinds, I bought mi 4. It’price is very lower. All feature are available in this phone. I have no word to say for this phone. Because it is a big smart phone. I use all app in mi phone. I have no hanging problem. I see If I want to purchase a other company mobile in same price so I do not think it would be so economical. Now in the present ( mi) is the best mobile company in the india. Mi have all feature moblie launched. Mi will launch all verity in moblie. There are many feature in my mi mobile. In last I say mi brand is the best in all company . Thank you
