Samsung has apologised after it accidentally sent an alert to thousands of devices overnight.
Affected devices received a notification from Find My Mobile in the early hours of Thursday morning.
Some customers complained on social media that it had woken them up, while others worried their device had been hacked.
In a statement, Samsung said the alert had been sent unintentionally to a “limited number” of devices.
Thousands of customers posted on social media and news site Reddit, many sharing screenshots of the notification and asking what it might mean.
