Let me talk about my experience with note 4. I got it(4 GB RAM version) a months back from local market by paying 600 extra than online price because i found it difficult to grab on flash sale.
As an average user I recommend everyone this phone who have a budget around 10k. And there's no issues with phone's performance , multi tasking, battery(most loving thing of note-4) and heating.
The only issue is mid quality camera and phone's heating when it is on charge. With one hour of usage in gaming it does not heat as much as it does in just half hour of charging. Plus dead pixels on screen is very high which is highly noticeable on dark displays.
But overall I am very satisfied with the phone.
