Review after 4 months of usage.
This phone is a full package.
There is no competition with redmi note 4 in the same price range.
You are getting 12mp back and 5mp rare camera but the quality is so good, though there is some negative affect of low light on the phone,
sound quality is up to mark, there is no lagging in the phone as I have experienced since past 4 months,
No heating problem is there.
Cons: sometime headphone jack makes the sound dull and u need to restart the phone to fux that problem.
Other than that phone is awesome. All the best redmi
