This is one of the phones that runs Indus OS. Indus OS is Indias very own operating system which has gained a lot of popularity because of its fast and simple UI and great functionalities. This powers Micromax Canvas Spark 2 Plus which is one great plus point to the phone. It has a decent battery with 2000mAh capacity. The 1 GB RAM packs a punch along with the 1.3 GHz processor which is very amazing feature for its price. Adding to that it also has a Quad core processor which gives a very descent performace at par with its predessor Canvas Spark. The 5 MP camera clicks very good pics in daylight but has some grains in the dark which is very much acceptable considering the price point. Dual SIM is a very common feature today and Spark 2 plus does not miss out on that too. Overall, its an amazing phone for 4000 rupees.
