The Karbonn A21 is now listed on and the Karbonn A9+ on Flipkart. The dual core smartphones from Karbonn Mobiles is here. The Karbonn A21 is priced at Rs. 11,999 on ebay where as in the newspaper ad it is around 10,500.

The A21 is dual SIM running ICS (Android 4.0) OS over a dual core processor clocked at 1.2GHz. I believe the processor will be the same as on the Karbonn A9+ i.e. from Qualcomm Scorpion. The screen is 4 inches as mentioned on ebay (which seems to be incorrect) and resolution is qHD as mentioned on the Karbonn site i.e with pixels resolution of 960×540 pixels which is amazing, however the specification tab on Karbonn site says 800×480 so needs confirmation on this too.

On Flipkart the A9+ RAM and internal memory is not mentioned however for the A21 it will be 1GB RAM and 1G storage. The 1GB storage seems too low probably it may be the storage for apps and another partition for internal storage of around 2GB (needs confirmation).

The camera is of 5MP resolution with 720p video recording capabilities. There is a 0.3 MP front camera (needs confirmation) for video chats. Other features are 3G, 2G, Wi-Fi, GPS, Bluetooth and micro USB port. The battery capacity is not mentioned, probably will be the same as on the Karbonn A9+.

Interestingly in the newspaper ad ( the price of Karbonn A11 as mentioned is 8,990 but does not specifically mention dual core instead says 1GHz ultra fast processor. And as for the Karbonn A21 it does mention dual core with and 1.3 MP camera.

The specs of Karbonn A21 listed below are as per the ads in the news paper which seems more genuine as it also has the Karbonn Toll number and Website address. There are quite a few changes and does not match with the specifications listed on the ebay site.
