Xiami is one of the fastest growing mobile company is india. I am using xiami Mi4i from last 8 months and I am fully satisfied with the performance. It has 16 gb internal memory with 2 gb Ram, 440ppi resolution, 2nd generation Qualcomm snapdragon with 4g support and many more.
One of the best part which I realy like in this mobile is there is no lagging problem and its awesome battery( 3030 Mah) .
But few problem I found in this mobile is that it has no external memory support and sometime phone gets heat. But in point of view every mobile have some defect and in the range of 10k to 15k its a best mobile I have ever used. And even I am sugesting my friends to buy this mobile if their budget is low.
Mi4i as per my experience is realy a good mobile.
