SAN FRANCISCO (KCBS)— In a major victory for San Francisco’s District Attorney George Gascon, Samsung has agreed to make anti-theft features available on its latest smartphone.

Gascon has been working with New York Attorney General Eric Schneiderman to get cell phone companies and carriers to agree to make the ‘kill-switch’ feature available on all mobile communication devices in order to render them useless if stolen.

There has been plenty of resistance to this initiative since the combined business of replacing cell phones and selling insurance generates nearly $38 billion in income a year for the mobile communications industry.

Gascon said the manufacturer has agreed to include the new anti-theft feature on their Galaxy S5 phones, sold by Verizon and U.S. Cellular.
