Hi,
I am looking to buy a new Smartphone, as as we all know there are lot's of options available in the market. But, i want a smartphone which includes all the new technical specifications which we assume to be in today's smartphone. Pointing towards my budget and as per my fantasy i marked down three best smartphone's Micromax A110, Iball Andi 4.3j and lenovo p700i but i just got damn confused that which one to choose. Please, give me some suggestion's and make my choice a bit easier.
