Lumia 1020 :: Getting Some Sort Of Reflection In Low Light Snaps?

Whenever I try to take a picture in low light example of a candle or a bulb I see a dot in my field of view which moves as i move my phone. It becomes worse when I try to capture multiple lights say for example an array of LEDs. It is very irritating to find something like this on snaps taken by such a good camera phone. What can be done about it? As you can see in images attached just above the switch board on wall in 1st and 3rd image and on edge of cupboard in a close up shot in 2nd image.
