Well on mine the white spot shows up in exactly the same spot every time, but only in photos taken with the camera under very specific circumstances. Specifically the photos have to be taken in very low light for it to occur. For example I took a photo with the lens placed directly on a black microfiber cloth, the entire image was black and the spot could be seen. Then I took a photo of a scene in the room that was well lit but also had a black area in the same location the pixel would be expected and it was not seen. What I gather from this is that in normal use I'll never see it. In the year I used my iPhone I can't think of one time I took a photo with it in darkness, and I took a lot of photos. So in my case it seems to be a situation that I can artificially cause by taking photos in dark places but who really does that?
What's that old doctor joke:
Patient: Doctor, my arm hurts when I do this.
Doctor: Then don't do that.
Sorry, couldn't resist. Seems the solution is to simply not take pics of the TP2 where the effect will appear.
The pics I posted show the dead pixel effect only when taking pics with the lights out or low, only when the camera I am using is in macro mode, at a certain distance between the lens and the TP2 display.
But using the TP2 there's nary a dead pixel, no matter the ambient light or what I am doing on the TP2. Said another way, there's no dead pixels on the TP2.
If I understand what you are doing (perhaps I don't) then the TP2 is not defective.
I think you're right, I can't reproduce the dot, which is white btw unless I takes photos in darkness. Your dot moves around but mine is always in the exact same spot. I'll just try to forget about it, my screen has no dead pixels when in use so I am thankful for that.
