To get around this, researchers Tilo Muller, Michael Spreitzenbarth and Felix Freiling from FAU put Android phones in a freezer for an hour until the device had cooled to below -10C.
The trio discovered that quickly connecting and disconnecting the battery of a frozen phone forced the handset into a vulnerable mode. This loophole let them start it up with some custom-built software rather than its onboard Android operating system. The researchers dubbed their custom code Frost – Forensic Recovery of Scrambled Telephones.
Not a good day for Android. Then again, not many days are good for Android.
