The DA of San Francisco wouldn't reveal how the two systems work. Apple's security plan is part of iOS 7 and is covered by a non-disclosure agreement. Apple did show off its Activation Lock at WWDC last month. Even if thieves try to wipe the phone, the device won't activate with an account name and password. For its part, Samsung has a deal with a third party security company to provide users with a subscription to a security service.
Since Google doesn't provide an anti-theft system for Android phones, Samsung has turned to LoJack to provide a branded solution to the problem. While it is similar to Apple's "Find My Phone," the LoJack system works hand-in-hand with police and does cost $29.99 a year. So far, the system is available only for the Samsung Galaxy S4.
Last month, both Gascon and Schneiderman started the Save Our Smartphone initiative, calling for manufacturers to add a remote control kill switch that could disable a smartphone in case of a theft, making them less valuable to steal. "I'm very optimistic that they came and were willing to share their technology with us," Gascon said.
