Let's say a thief steals your phone, as phone thiefs tend to do. One of the first things they will do is turn the device off to help keep the product from being tracked, just in case. Once they get home or whever they want to toy with the phone, they will have to turn it back on to try to unlock the device or factory reset it.
Therefore, I would like to see Webroot SecureAnyhere upload the location of the device to the users Webroot account whenever the device is turned on or off. That could potentially be the one difference in locating a stolen device.
