The best thing done by Mi is that Mi launched its Mi note 4 which can compete with flagships of oppo and vivo.
The 4gb/64gb version is the best for gaming experience and the quality is also good which provide date on images.
But the little bit dissatisfaction with Mi note 4 is its heating issue.
Otherwise the phone is excelent in range and can compete with mobiles upto range of 15000 Rs.
