Following their announcement from last week, Google has launched the Android Device Manager, a native method for locating, ringing and wiping your Android devices from any browser. Logging into ADM lets you find your device on a map, make it ring, or erase all data on the device.

This much-needed functionality is being rolled out slowly to devices running Android 2.2 and above. You might need to enable it on yours, which is as easy as hopping into Settings > Security > Device administrators, and checking Android Device Manager in the list. Once you've done that, you can access ADM on the web and view your device's location accurate to within 24 meters . We're waiting to hear back from Google as to whether this works with only GPS or A-GPS.

Similarly, if you want to be able to erase all your device's data remotely, you'll have to first enable factory reset on your device - the ADM browser page can send a notification to your device to let you quickly find that option.

Obviously, this is useful for when you lose or have your phone stolen in a public place, but it's also a simple way to find your phone around the house in case you can't spot it - just ring your device from the browser.
