Lenovo A6600 plus come with 4g supported phone. In that phone we got 5 inch display dual sim phone, 2gb ram 1GHz quad core processor 16 GB intenal storage and 32 GB expandebal that not enough. About camera that will be 8 megapixsel back and 5 megapixsel front in touch focus and auto detection features but camera was not really good. In Android O.S v6.0 Marshmallow available in that phone. Here we got 2300mah battery that will be removable. This phone you get in indian market price between 7000 to 7500 in that range. If u think you want to buy this phone so dont buy. Then I suggest u moto e3 that phone campare to this phone is much better. So I hope u like my review. Thank you.
