Just a few days ago Google had announced Android Device Manager. This would at least bring Android OS with the ability of wiping, locate and soon be able to lock your Android device.
Unfortunately its not available on all Android devices. As I was testing on a few devices of mine. On my wife’s Galaxy SIV the Android Device Manager wasn’t available under the Google Settings in the apps. This is the Green icon in your apps that is called Google Settings, has a letter “g” and sort of a gear icon.
