In one case, the researchers said the vulnerability was so severe that the only way to rescue a targeted iPhone would be to delete all the data off it.

Apple released fixes last week.
But the researchers said they had also flagged a sixth problem to Apple, which had not been rectified in the update to its mobile operating system.
“That’s quite unusual,” commented Prof Alan Woodward, a cyber-security expert at the University of Surrey.
“The reputation of the Google Zero team is such that it is worth taking notice of.”
