Well this phone is little bit cheaper than Karbonn A25 but all the specs of Karbonn A7 Star somewhat roam around the specs of Karbonn A7. Taking processor into account then it has got 1GHz processor which is supported by 512MB RAM and then the battery strength is also poor which is just 1400 mAh as compared to the 2000 mAh which you will get in A25. It is a Dual SIM phone which will support GSM bands on both the SIM slots and as likely to the Karbonn A25 it does not support the 3G connectivity. The camera specifications are pretty much similar where you will have 5MP camera (along with LED Flash) as the primary camera at the back panel and a 2 MP camera in the front mainly for the video calling purpose. The internal storage capacity of the phone is 164 MB which is less when compared to that of Karbonn t A25 (512MB) and it can be extended up to 32GB. It will support 2G connectivity for the cellular data exchange and you also have Bluetooth. As far as the operating system is concerned then as the other devices in the same price range it will operate on Icecream Sandwich and you can click here to buy this product from Snapdeal.
