It has been more than an year now I am using the Xiaomi redmi note 3, I am very much satisfied with the phone and its working very fine. The look of the phone is really good, good build quality, it has got metal body, sleak and no issues what so ever. There have been many questions on the heating issues but I did not feel any issue as such. Yes, if at all you are facing any of such issues I would recommend you to take out the back cover or the protective cover and use it. That would help the heat to get dessipated. Thank you.
