As I mentioned, this is my 2nd note 4. First one bought 4 months ago (3+32 variant) and gifted to my wife. She is very happy as 2 primary requirements were met.
1. Absolutely no heating issue.
2. Very long battery back up.
Also I bought 7 Redmi phones for my colleagues in 4 months. But it's little disturbing that everyone requesting to get them Redmi phones as they were unsuccessful to order. Presently 4 colleagues are in queue for Redmi 4 model (30th sale).
I'll post detailed pros & cons soon.
