Android device manager is a web based service which lets you keep a track of your mobile phone, ring it and wipe away data remotely. These features are like a boon in case your Android device has been misplaced or stolen.
Recently Android Device Manager settings was reported to appear on some Android devices and now Google has made the website leave. It clearly hints that the feature will soon be rolled out to other mobile devices as well. However, if you are on a device with Android 2.1 or older, you won’t be able to use the features offered by Device Manager.
