I have purchased this product in the month of November everything went cool till now .In recent times I have came to know that Redmi mobiles especially Note 4 were bursted and chargers are also bursted in my neighborhood houses. Overall the mobile and its features are wonderful. Somehow by its metal pannel mobile generates heat while charging and browsing the net .The main thing is it shows always to clean the cache file they were over 200 or 300Mb.My suggestion about this mobile is proceed but use carefully otherwise it may burst.
