I have bought a brand new redmi note 3 smart phone. But I found that its proximity sensor is not working. But over all other features of the smartphone are brilliant. Its performance in gaming is good enought and im very much satisfied with the pricessing speed but again its sensor is very bad. Service center is also a major issue for redmi phones. Service providers are not satisfying there coustmers properly. If redmi india wants to stay in the market they have to enhance there service.
