Help Camera problem lg p350

[ldi]

Hi, I bought the lg p350, but when I try to shot a photo outdoor or however where there's some light, in the preview and after the shot, there are some pixels of the image that are purple in particular the contour of the objects for example of the clouds, here some example to show the problem:
