Spice stellar 600 this is the worst smart phime that I had ever used in my life and seriously I am very much disappointed by this smart phone. My mother had gifted this phone to me on my last birthday and and I was very much happy because of the screen of this phone, firstly if I talk about the design, their is nothing special in the design of this phone. The weight of the phone is like a brick its to much heavy and the worst feature of this phone is the hanging problem, it hangs any time if you are talking to some one its restarts automatically. The worst worst worst phone.
