This phone has a great build quality . This phine does not have gorilla glass protection even its display has nice build protection glass like gorilla glass. I use this phone . This phone has nice camera qulity back camera is nice but front camera I think not good as given px. And one think that is bad in this phone its back panel back panel of this phone gets screches very quickly so this is bad thing . And its performance is very very good its MIUI works prety smoot and this phone has great sound quality even earphone . This phone comes with snapdragon 650 that mens we play games of high quality .this phone has hibrid sim slot support 4G . So this phone is good I suggest to you buy this phone.
