Please don't use my image in a wrong context.
We I took that pic, I was using the original kernel from nokia.
I think the problem came from a defective or not well fixed cable between the screen and the motherboard.

The problem stopped 3 days after that photo and, one year later, I'm still using that phone, now with kp v50, sometimes with dsp profile to watch h264 vids. It works like a charm.

So yes, stop spreading FUD
