The focus of this segment is now on all round performance rather than on great hardware with old software or vice versa. Here is a list of devices one may consider while aiming to purchase a smartphone for less than Rs 20,000.
Nokia Lumia 800
Nokia had introduced its Windows Phone 7 based Lumia 800 smartphone with a unibody design inspired by the Nokia N9 smartphone.
