I bought my Redmi Note 3 Pro, 3GB Ram, 32 GB ROM on May 2015 Approx. Mobile is excellent in all features. Good Speed, good touch, Nice design(metallic body), everything good. Only camera quality is average than others.
since I am using this phone from 1 and 1/2 year. I am facing some issues: Only battery charging port some times irritate me. coz its being loosening when you connect ur phone to charging cable. But I changed my cable and issue resolve and after some days its again started. only 300? taken and you can replace charging port(or you can buy on ebay).
and 2nd problem is that its audio 3.5mm port is not working totally.
only these are the problems otherwise battery backup and and others are excellent.
