The prosecutors said they "asked the companies to commit to develop effective solutions to this national crime wave and install them on all new products within one year."
Almost 1 in 3 robberies nationwide involves the theft of a mobile phone, according to the Federal Communications Commission, which is coordinating the formation this fall of a national database system to track cellphones reported stolen.
"Together, we are working to ensure that the industry imbed persistent technology that is effective, ubiquitous and free to consumers in every smartphone introduced to the market by next year," the prosecutors said.
Nearly 175 million cellphones mostly smartphones have been sold in the U.S. in the past year and account for $69 billion in sales, according to IDC, a Massachusetts-based research firm.
Lost and stolen cellphones cost consumers more than $30 billion last year, according to a study cited by Schneiderman in June. In New York, police have coined the term "Apple-picking" to describe thefts of the popular iPhone and other mobile products like iPads.
Phone thefts comprise 40 percent of all robberies in New York City, authorities said. In San Francisco, half the robberies were phone-related last year.
