Android Device Manager
As you may know, Google launched its web-based Android Device Manager a month ago and it helps you to locate and erase your lost phone or tablet remotely. The new website allows users to search for their lost devices and shows the current location on the map with the ability to ring an alarm or erase the storage. Thanks to Google, here comes the new feature for remotely lock, this is very useful if you just misplace your device, but don’t want to erase the storage.
Android Device Manager supports all devices running Android Froyo or later, to get started just visit the website – www.google.com/android/devicemanager
