ABS: Android in space

In reality that's a bit paranoid because it would require both malice and foreknowledge and means (access) to achieve some sort of delayed-action Nexus bomb. None of those conditions obtain as far as I can tell. I would say the risk is very low, higher risk would be very garden variety issues such as an exploit in the Skype client and even then the amount of damage the device could do is intentionally low.
