We recently introduced an anti snatch feature on Omerta handsets - a simple mechanism that utilizes the accelerometer of the phone to monitor for rapid movements which could indicate the phone has been snatched out of your hand. If triggered, the app immediately locks the phone.
Whilst I envisioned this as mechanism to protect your phone from low level nuisances, such as friends grabbing your handset or more maliciously, a street mugging, it transpires snatching a phone to prevent the user from locking it is a legitimate tactic by UK law enforcement for obtaining data from a suspects phone!
Since an unlocked phone represents a gold mine for data recovery, in this instance, Police staged a street mugging, obtaining the phone whilst it was in use & then continued to swipe the screen to prevent locking until they could download ALL the phones data!
How sorely disappointed they would have been had the handset been an Omerta! Read more about the incident here - https://www.bbc.co.uk/news/uk-38183819
