The Redmi 3S comes with octa-core Qualcomm Snapdragon 430 processor, which runs at a speed of 1.1GHz. The processor is supported with Adreno 505 GPU. Both the phones support expandable storage up to 128GB using a microSD card.
The smartphone sports a 5-inch IPS display with a resolution of 720 X 1280 pixels. It runs MIUI 7 based on Android 5.1 Lollipop.
The latest Xiaomi phone also carries a fingerprint scanner under the camera on the back. The Redmi 3S has a 13-megapixel camera with LED flash and f2.0 aperture. The smartphone also has a 5-megapixel front camera. Both the cameras are capable of recording videos at 1080p resolution.
The dualSIM phone has a hybrid SIM slot, which means the second slot can also be used for a microSD card.
Despite packing a massive 4100mAh battery, the Redmi 3S is pretty light at 144 grams. The phone will be available in grey, silver and gold colours.
Xiaomi last month launched 6.44-inch Mi Max phablet in China. The Mi Max is expected to be launched in India soon.
