I guess when we are looking at a smartphone at the price of Rs 2999/- we donot have much expectations out of it. I had purchased for usage on a temporary basis as well.
Operating system - It is powered by Android v4.4.2 KitKat operating system with 1GHz processor, 256MB RAM, 512MB internal memory expandable up to 32GB.
Battery - The battery can support for 24 hours with minimal usage as per my personal experience.
Camera - This phone comes with primary and secondary camera of 2MP and .3 MP respectively. However, one should not expect much in terms of camera quality. Lesser said, the better.
Sound - This can be an issue. Voice does not tend to be too clear, while you receive a call and as well as to the one you are speaking with. It is not for extensive use and can be used for secondary purpose.
Suggestion - Good purchase for a secondary phone purpose. Difficult if the purpose is to maintain it as a primary phone.
