On the way home from the doctors there was a strange buzzing noise for a few seconds. We couldn't locate it and no warning lights came on so...
A couple of minutes later another odd buzzing sound, different but again we couldn't locate it.
Just as we parked up Paul received a text message. Seconds later so did i. No rush, we'll check when we get into the house and get a cup of coffee.
While making coffee i checked my phone.
The lock screen had been taken over by a message.
ALERTE - ALERTE - ALERT.
Test by the prefecture of the Dordogne. Blah, blah, blah.
The text message was the same message.
Concerning and interesting, it seems they can take over my phone and bypass the lock screen security code to get emergency messages out.
