The two smartphones are well-matched in terms of specs and features. Both phones are powered by Google's Android Marshmallow OS,  The Mobile Indian reported.

However there's one slight difference between the two, it's the microprocessor, the heart, and brain of the mobile device. The challenger, Micromax Evok Note is powered by a MediaTek MT6753 processor, while the Xiaomi Redmi Note 4 is powered by the Qualcomm Snapdragon 625 processor.
