13MP rear camera, 0.1s Phase Detection Autofocus

Life isn't perfect, but it has perfect moments. A good camera should make capturing them as easy as possible. It starts with a quality camera, which has Samsung as one of our key suppliers. After rigorous testing, we discovered that Phase Detection Autofocus (PDAF), typically found in professional DSLR cameras, shoots faster because it simulates the human eye when focusing on objects, shortening focus time from 1s to 0.1s

Actively adjusts for night and day

Redmi Note 2's display is optimized especially for the young and active. When hiking under strong sunlight, Sunlight Display intelligently adjusts contrasts for each pixel in real time to improve readability. When watching your favorite TV shows at night, Night Display dims brightness down to a comfortable level. Reading Mode reduces blue light emissions and prevents eye strain, which is great for reading up on study notes.
