The problem you are encountering is called a "dead pixel". Every ccd has several dead pixel, so it is quite normal. But I agree that it can be annoying.
The solution is to map the bad pixel and to substract them afterhands.
Go to http://chdk.wikia.com/wiki/Main_Page and download the latest firmware for you camera here http://mighty-hoernsche.de/.
It is a supplement to your camera that will open hundreds of possibilities, like making time-lapse recordings, doing your own scripts, shooting RAW,...as well as a feature for removing bad pixels.
All you have to do is to read! Yeah, I know, there are lots of things written :p
More specifically, here is the "how to use badpixel removal" explanation.

My daughter has a Galaxy S4 mini and there are these purple dots that are invading the pictures she is taking - they only show up when using the camera mode and show up in the pictures taken - is ther


Although the camera is very tiny, if there is a very small opening, it could be some moist came in. The moist can leave very small crystals on the sensor, causing dots in the picture. On a normal camera, you could test this, by choosing a large aperture number (f number of 22 or more) focus on infinite and take a picture of a bright white paper with lots of light on the paper. If you then see spots you know they are on the sensor. I'm not sure the Galaxy can be set to manual, to take a spot retention picture.
If the camera is important, you could go to a repair shop to have it replaced.

WHITE DOTS ON SCREEN NEED DIAGRAM LOCATION AND REPLACEMENT HLT 56765X/XAA


White dots that increase in number as time goes by indicates that the DLP chip needs to be replaced. Samsung use to cover this problem under their "white dot" warranty. You can call 1-800-samsung to see if they will repair it. If not, they can give you the closest service center. I would not attempt this repair unless you are a trained tech.

No setting can cause white spots on the picture, this is a fault.

By the way you can reset settings on this camera to initial state by simply removing and putting back camera batteries.
Alternatively you should have a reset command on camera settings menu.

My opinion is that this is a fault and not a settings problem.

Typically there are three kind of faults that can cause this problem:

1 - Dirty lens or water inside the lens:
The lens may be dirty inside, for example because of water condensation on internal surfaces, this will cause blurred dots or black dots. The lens must be taken apart and cleaned in this case.

2 - Defective CCD sensor.
The CCD sensor is the chip that detects the picture, if you get well defined white or colored spots on picture that is probably a defective CCD. I think this is the more likely in your case. To fix this the sensor must be replaced.

3 - Defective video chip on internal board.
This can cause any kind of problems, however it is quite unlikely.
It is an expensive repair.

RED DOT


Hi,

If the dot is not visible in print, but only on the camera's screen, the its only the LCD that is faulty.

If the dot is visible on screens and in print, then yes, it could be the sensor. Try taking pictures without the digital zoom. Chances are the dot is only visible with the digital zoom because the picture is interpolated.

If all else fails, you can try cloning out the spot in an image editor on the computer.
