I am using this product from last 8 months
I worked smoothly first 2 months then its the worst product.
It cost me 10k rs for 3gb ram and 32gb rom from reatil store
It has 13mpixel rear and 8mega pixel back camera but the quality of photo is too bad.
It becomes hot even after a little processing
It battery capacity is 4000mah and dolby atmos sound.
If you are about to purchase, I recommend not to buy this instead buy redmi note 4 more specifications
