Xiomi the chinese mobile company is now on the fire and compiting with the giant companies like Apple, Samsung etc. The Mi4i is the slimiest phone with better look. It has a 2 GB RAM and 16GB ROM. With a high quality camera of 13MP. The phone is hang free and it runs almost every games very smoothly. I bought this a while back and as I am fond of NFS game I intsalled the most wanted series. The worked very smoothly as expected.
Moving towards the camera quality the first thing why I bought the phone was HDR focus option in camera which at that time I guess was only in Mi4i series.
This option let the user to focus on the particular object which make the captured picture look like it was taken from a dslr camera. Thus feature was so good that it also let the already caputred pic to add filter like that.
