Bangalore based smartphone maker Karbonn has expanded its budget smartphone line-up with the launch of Karbonn A3 and Karbonn A4.

Both smartphones are Dual-SIM devices and run on Android OS v2.3.6 Gingerbread powered by 1GHz processor.

One striking feature of these two budget smartphones is that despite being priced less than ₹5000, they pack two cameras. Karbonn A3 houses a 3.0-megapixel main camera and a secondary camera on the front side, while Karbonn A4 sports a 3.2-megapixel on the rear side and a front camera.

Only a handful of low-cost smartphones in the market in the sub-₹5000 range feature dual cameras.

Both Karbonn A3 and A4 are listed on e-retailer Flipkart.
