I recently moved down from the 925 to the 521. I use the camera a lot and up until this evening the camera has been very snappy. But now after pressing the button down halfway and getting the pre-focus beep, I finish pressing the shutter button and then there is about a 2-3 second delay before the pic is taken. Ive tried restarting the phone but that didnt help. Any other suggestions I can try to clear this up would be greatly appreciated
