I bought a HTC Desire X recently and found that 720p recording and playback. Can you tell me if I can shoot 720p videos on the Desire X by installing Camera Zoom FX apps? If not, are there any camera apps that enable 720p recording and playback? And please tell me if it is prudent to buy the Samsung Galaxy S Advance (it comes with Gingerbread)? Coz If i'm buying a phone i'm keeping it for at least three years. Please reply soon.
