Android Device Manager (ADM) was announced yesterday, and Google led us to believe that it would begin its roll out sometime towards the end of the month. But much to our surprise the Device Manager has already been pushed out over-the-air to some Android users via Google Play Services.

Reports have been flying in from users all over the world – not just the U.S. – informing us that they started to receive the update during the early hours of this morning.

In order to see if ADM is ready for your handset you will need to navigate into Settings, then head into the Security section and tap on the heading entitled “Device administrators.” If the service is available for your device you should see a single option with a checkbox labelled “Android Device Manager,” if this is present tick the checkbox and click the activate button.

If you haven’t received the Device Manager yet, don’t worry. A devoted Android enthusiast, Moritz Jordan, posted the APK for us to download and install on our devices. Obviously great care should be taken when installing the file and normal concerns of security still apply. If you wish to download the Android Device Manager APK, click here.

I am one of the user’s who has received Android Device Manager over-the-air via Google Play Services on an Android device this morning. However, at this precise moment in time the service is practically useless as the Web and Android manager applications are not yet accessible.
