Good phone .Using this device for the last 20 days. Satisfied with the touch sensitivity, performance and battery back up. However, I am not satisfied with the camera quality. It does not have many features and HD quality is missing. My GIO 4G sim is not getting network , though the vodafone one is getting signal in both the slots; not sure about the reason behind it. After using 5 consecutive sets of samsung, I went for Nokia brand and feeling neutral about it.
