On iPhones this will be labeled “Find My Phone,” while on Android devices, it’s called the “Android Device Manager.” This program will track your phone’s location and relay this information to the cloud. It’s important that you set this feature up while you still have your phone with you, as there is no way to enable Find My Phone if your phone has already been stolen.   Find My Phone is a component of Apple’s cloud-based server, iCloud, which backs up and stores your phone’s data. If you have not yet set up an iCloud account, you won’t be able to use the Find My Phone app. Set up an iCloud account through your phone’s “Settings” menu, then locate “iCloud” and tap the “Account” to sign in.  In order for the Device Manager to locate your stolen phone, you’ll need to have the GPS-tracking “Location” setting turned on. You can turn Lost Mode on remotely: you’ll need to login to your iCloud or your Android Device Manager account, and can turn on Lost Mode from there. With Lost Mode turned on, whoever stole your phone will be unable to login and shouldn’t have access to any of your phone’s data or apps.  Once you’ve recovered your missing phone, you can turn off Lost Mode by entering your passcode on the phone’s home screen. Even if your iPhone or Android is offline (not connected to the internet), you can still remotely lock the phone. You’ll do this through logging in to your online account. Any settings that you change on your device will take effect the next time the phone is online. If your iPhone has been stolen, you can track its physical location online at www.icloud.com/find. This will bring up a map showing the current location of your phone. The map will show real-time movements, so if your phone is on a bus or subway car, you’ll be able to follow it along the map.  If your Android phone has been stolen—or you prefer to setup your account on a computer rather than on your phone—you can access the Device Manager online at: www.google.com/android/devicemanager.
