In Google Play there is a header button for 'My Apps' which lists all of the applications on my phone. Because it is lost I want to activate the Android Lost app, but when I click on the thumbnail icon I can't find a section such as 'Personal Notes'? Sorry to sound silly
When you log into your Google account you can search for Device Manager www.google.com/android/devicemanager and you will be able to find your Android device.
