Without a built-in “find my phone” function in Android, you’ll have to rely on third-party options. Cerberus is an excellent stand-in, with lots of options for remotely tracking, wiping and managing your phone. The app can even take a photo with your phone’s front-facing camera when it detects several failed login attempts. It’s free to try for seven days, and costs $4 (one-time fee) after that.
