If you do not have blue-tac, a small ball made of bread can be used to cover either the entire IC or only its sides.

Re: Why is the PI2 camera-shy ?

I bet on a zener somewhere in the on-board power regulator.

Re: Weird: If you take a photo of Raspberry Pi 2 it crashes!

The IR light emitted by a Remote Control for TV should also be tried to see if it has any effect on Raspberry Pi 2. It should be also checked if the board is sensitive to Arc Welding. Quite important, test Raspberry Pi in the street to see if it is sensitive to Xenon and other kinds of headlamps. ht...

Re: Weird: If you take a photo of Raspberry Pi 2 it crashes!

Does Raspberry Pi 2 crashes, freeze or turns off in bright Sun? From what I have read till now a Xenon Flash and Laser Pointer induces glitches causing the board to malfunction. Normally the strong light of the Sun should do the same.

Raspberry Pi 2 is so different from the previous models and so new that likely it could have some issues. Let other people discover them and buy a stable Raspberry Pi 2, with all bugs fixed, next year.
