"A "master key" that could give cyber-thieves unfettered access to almost any Android phone has been discovered by security research firm BlueBox.
The bug could be exploited to let an attacker do what they want to a phone including stealing data, eavesdropping or using it to send junk messages.
The loophole has been present in every version of the Android operating system released since 2009.
Google said it currently had no comment to make on BlueBox's discovery."
