Everytime you turn off a mobile device, it clears the cache of previous 
alerts.

You will receive the alert again when you turn the phone on, because the 
cache will be empty.  In theory, after receiving the alert, the serial 
number will be in the cache.

I do not know why Apple and Google software engineers have trouble with 
their phone software.
