Which mobile should i buy? - 1

Among all moto g gen 2 is the best choice.

I have analyzed all three phones & as per features, price range or the market value I would love to suggest you Lenovo S850. Features of this phone are as per Android v4.2.2 (KitKat), 3G, Wi-Fi, 13MP primary camera, 5MP secondary camera and lots more. This is the most popular phone priced around 14K. I think you should go for it.

Moto G 2 Gen is best at the price of Rs. 12999. This phone is loaded with the latest Android V4.4.4 Kitkat, 1.2 Ghz Qualcomm Quad Core Processor, 1 GB RAM, 16 GB memory which is Expandable Upto 32GB, 8 MP Primary Camera and 2 MP Secondary Camera.

5 Inch LCD HD display is having resolution of 720 x 1280 Pixels with Corning Gorilla Glass 3. With that you will get Android L Upgrade very soon.
