Lenovo A6000 plus is very good smartphone packed with a variety of features.It comes with a mediatek processor of 1.2 GHz power which is quadcore.So the processing is very quick.Also you get a 2GB RAM which makes it even better for multitasking.It offers dual sim and supports 4G as well.Inbuilt memory is 16GB and can be expanded to 32 GB if you wish.
It has a 5 inch screen which is large and offer hd display.The sad thing is does not have a protective glass like gorilla glass but lenovo provides free screen guard out of the box.The camera is good for the rear which is 8M and the secondary camera is a 2M one which does not offer much.All these features are available for a mere RS.7502 only and is available on paytm in black and white coloref models.
I suggest you to buy this phone
