WASHINGTON — The Justice Department will start revealing more about the government’s use of secret cellphone-tracking devices and has launched a wide-ranging review into how law-enforcement agencies deploy the technology, according to Justice officials.

In recent months, the Federal Bureau of Investigation has begun getting search warrants from judges to use the devices, which hunt criminal suspects by locating their cellphones, the officials said. For years, FBI agents didn’t get warrants to use the tracking devices.
