Find My Device lets you remotely track, lock, and erase the data on a lost or stolen phone.

Android Device Manager has picked up its first major update in two years, bringing a new visual layout and a new name: Find My Device. The app's functionality isn't changing — you'll still be able to remotely track, lock, and erase the data on a lost or stolen phone — but the interface has picked up much-needed polish.

With the rebranding, Find My Device is now a part of Google Play Protect, a suite of services designed to protect your phone from malicious content. Google is leveraging its machine learning expertise to scan and verify the apps installed on your phone, and while the Verify Apps feature has existed since the Jelly Bean era, Google is making the process much more visible to users.

With Find My Device, you'll also be able to see the battery life remaining on your phone and the Wi-Fi network it is connected to. Here's what you need to know about Find My Device, and how you can set it up on your phone.

How to erase your lost phone's data remotely

If you're certain that you're not going to see your phone again, there is the nuclear option of erasing the data remotely. Selecting the Erase option deletes all the data on your phone. The service also deletes data from a connected SD card, but there is a chance that it may not be able to, based on the manufacturer and Android platform version. Even if your phone is switched off when you send the Erase command, the factory reset process will be initiated as soon as it goes online.

  1. Locate your phone on Find My Device.
  2. Tap Erase.
  3. Confirm deletion of data by hitting the Erase button.
