Android Device Manager; Find your Lost or Stolen Devices
A long time flaw in the Android OS had recently been addressed by Google, the absence of a lost phone feature in which users could remotely manage, find, lock and erase their phones. Much like the find my iPhone feature you would find in iOS devices. This is a very useful feature, especially if your phone had been stolen or lost.
Many users we’re having to out-source third party apps such as Cerebrus and PlanB to locate their lost or stolen phones, which isn’t a very good solution from anyone. Don’t get me wrong, I’ve used Cerebrus myself and its an extremely powerful app, but having to outsource security features for a platform as popular as Android, just isn’t a good thing to do. It seems like Google has now agreed that they should provide some sort of security features, as Apple do with their iPhone and allow their users to locate their devices in times of need.
Google has reportedly released Android Device Manager, various user based sources such as Reddit confirm that ADM has already begun to rollout to users. Being a part Google Play Services, it will automatically and silently be added to all devices running Android 2.2 and higher.
It’s a simple process to see if the feature has been installed into your device. Navigate to Settings > Security, open the Device Administrators section.
You should now see Android Device Manager and other system apps that you have installed. Users from all around the world have posted screenshots of ADM, which means this app is not restricted to the US. The roll out has not reached every user yet, but it should soon. If you simply cannot wait ADM to hit your device, you can download the APK via these Android Police links. Be sure to update this through the official Play Store.
Also note that using Android Device Manager requires the web interface, which doesn’t seem to be released to be public yet.[Source: AndroidAuthority]
