I have huge expectation on my Samsung Galaxy tab 680. But my half of my expectations only full filled. Its specifications is quite normal and processor is not upto the level. Its specification not upto the price. The primary and secondary camera is worst when to smart phone. The processor speed is low and unable to play games. Dual band and WiFi hotspot is additional features to this tab. The battery backup s not at all statisfactory level. Within a hour ut reduce to 50 % . Update is literally critical to this tab. I will recommend to buy this tab to others
