Design and speed superb , as it has more ram . best part is cheaper than others . superb experience using its 4100 mah battery . over all a good smart phone at its price , but after some time it will show some problems like speaker , mike , sound quality , network while calling . as it’s camera is far worst than mi a1 , it’s photos r not mind blowing . but miui 8 or 9 is fantastic with its new feature . so over all buy it if u can’ t afford costlier than this .
