Helium implicated in weird iPhone malfunctions

The iPhone user guide warns that proximity to helium can impair functionality and that to recover, devices should be left to air out for a week or so in an environment far away from the rogue helium.

Smartphones contain microelectromechanical systems (MEMS): tiny mechanical systems that are integrated into chips.

That's probably the weirdest way to make a smartphone stop working that we've heard. As for why non-Apple devices appear to escape without harm? They might use different seals or perhaps aren't using MEMS devices in such critical roles.
