Micromax canvas 2 ( 2017) us one of the wrost android phone under 12000. The features it gives you is also available in some phones that costs only 8000-9000.
The main problems that I faced at the time of using this phone are
Screen resolution is not good. You do not want that much bad screen resolution which costs you 12000.
Battery drains very quickly. Although it has a battery of 3050 mAh but it only runs around 8-10 hours after full charged.
This phone lags a lot. Whenever I play some game like 8 ball pool it lags too much.
So, my friends, I will suggest you to buy sone other phone of this budget.
Thank you
