Losing your Android smartphone or tablet can be stressful, since, these days, it feels like your whole life is on it. Android's Device Manager helps you locate, and if necessary, remotely lock down your device or even wipe it clean in case of theft or after you've given up on finding it. The first thing you need to do is make sure that you've enabled this feature and properly prepared your device.

Check Your Settings

While you have your device in hand, check to make sure you've enabled the device manager. Depending on the model you have, you'll either have a separate app called Google Settings, or you'll have to go into settings and scroll down to the Google option. (If your app drawer has a Google folder in it, you'll find Google Settings there.) From either, you then tap security, and you'll see Android Device Manager. Here you can enable or disable a setting called "remotely locate this device" and "remote locate and erase."

To remotely locate your device, you'll obviously have to enable location services, which can eat up your battery, so it's something to consider. The device's location information is not required to lock and erase your device remotely.

For obvious reasons, you must be logged into your Google account on the device as well. Also be sure that you haven't hidden the device on Google Play or it won't show up in the device manager.

Test the Device Manager

Once you've verified that you have the correct settings in place, it's worth giving the device manager a test. Go to: and log into your Google account. The device manager will attempt to detect your smartphone, and if location services are on, will reveal its location.

If it's working, you'll see a map with a pin dropped at the device's location. On the left side of the screen is a box with your smartphone's model number, the time it was last located, and the date it was last online. Beneath that you'll have three options: ring, lock and erase.

What You Can Do With the Device Manager

Once you have it up and running, you can do one of three things with the device manager. First, you can make your phone ring, if you can't find it at home, or think you just misplaced it. Of course, if your phone is on silent, this won't help.

Second, you can lock your phone remotely if you think it's lost or stolen. In this case, you'll create a password that will replace your lock screen (whether you unlock your phone with a pattern, pin or another method. You can also add a recovery message; for instance, contact information for a good samaritan who wants to return the phone.

Finally, if you don't think you're getting your device back, you can wipe it so that no one can access your data. Wiping performs a factory reset on your device, but Google warns that it may not be able to erase your SD card if you have one. Also, if your phone isn't connected to the Internet, you won't be able to wipe it until it regains a connection.

Alternatives to Android Device Manager

Android users always have a lot of options, and this is no exception. Samsung has a feature called Find My Mobile, which is linked to your Samsung account. Once you've registered your device, you can use Find My Mobile to locate your phone, ring your phone, lock your screen, wipe the device, and put it in emergency mode. You can also unlock the phone remotely. Again, you'll need to have location services on to use some of these features. There are also a variety of third-party apps that can help you find your Android phone.
