Track your Mobile for free!!!

This great thing is done by Android Device Manager which is inbuilt in every smartphone device. You can track you android device at whatever distance it is. And also a great new feature is that you can erase your data remotely without wifi on that device or even if it is switched off. Hence now if you misplace your device then android device manager will come to use as your security guard.
This feature is the best and is not available in Apple’s IOS or any Windows Phone. Hence ADM is the Best.
