The company, which entered the Indian market last year, has launched three devices here so far -- Redmi 1S, Redmi Note and Mi3 -- in partnership with e-commerce major Flipkart.
"You are invited to a front-row view on January 28, 2015...Mi hits a 4 and a 6," Xiaomi said in an invitation.
Often called the Apple of China, Xiaomi launched the Mi4 in July last year. However, the device did not hit the Indian market.
Last week, Xiaomi had launched its flagship smartphones, the Mi Note and Mi Note Pro, at an event in Beijing.

Earlier, Xiaomi India Head Manu Jain had said the company would aggressively expand its product portfolio in India, which is its largest market after China.
The Xiaomi Mi4 has a 5-inch IPS display and is powered by a 2.5 GHz quad-core Snapdragon 801 processor and has 3GB RAM.
It comes with a 13MP rear camera with LED Flash, Sony IMX214 BSI sensor and 4K video recording. With a 8MP front camera, the smartphone comes with Android KitKat operating system with a layer of the MIUI OS skin.

Korean handset maker Samsung led the smartphone market with 24 percent share, followed by Micromax (20 percent), Lava and Karbonn at (8 percent each) and Motorola (5 percent).
