If I use superzoom in low light conditions there are some light red or blue dots, perhaps something like stuck pixels on the sensor. They are always in the same place.
I don't have that when using the zoom on the normal camera, or when taking non-zoomed pictures.

Could anything be done about that? If it is really the sensor it might be difficult. Perhaps a workaround would be to fill in the part with the average of the surrounding pixels?
(note that I am not really using the zoom in low light conditions, so the question is mostly academic)
