The Redmi 1S also features an 8-megapixel rear autofocus camera with flash, alongside a 1.3-megapixel front-facing camera.
The Redmi 1S comes with 3G, GPRS/ EDGE, Wi-Fi 802.11 b/g/n with Direct and hotspot functionality, Micro-USB, Bluetooth 4.0, FM radio, GPS/ A-GPS, and USB OTG connectivity options. It is powered by a 2400mAh battery, weighs 158 grams, and has dimensions of 137x69x9.9mm.
