It was released in AUGUST 2015 and worth purchasing at that time. Now more mobile are available with the same price and greater than greates feature at that rate. It supports two SIM out of which only one SIM supports 4G network. Somewhat heavier and thicker(weight is 185gms and 9.5mm thick). Fornt camera is 5mega pixel and rear camera is 13 mega pixels. It has 2GB RAM and 8GB internal storage. I was about to buy this mobile but then REDMI NOTE PRIME came into market. If you already own one then no problem. But if you want to purchase it I will suggest not to buy this.
