Samsung has issued an explanation and an apology to its mobile users who received a 'mystery' message in the early hours of Thursday.
Some customers were startled and awoken by a notification on the 'Find My Mobile' app, leaving a number to believe their phones had just been hacked.
Thousands of users took to social media and Reddit to complain to the technology company asking what it meant - all sharing the same screenshot from their phone screens.
One shared to Twitter: "Got a mysterious find my mobile notification. Was scared that someone tried to track me but it seems thousands of people got this? @SamsungMobile what's happening".
Another posted: "So myself and many other Samsung users have all reported receiving a notification from the "Find My Mobile" app saying "1".
"I clicked it and nothing happened. Check app info and it used 20% of my battery? Did all our phones just get hacked?"
The alert, which appeared to have affected any Samsung device with the Find My Mobile app installed, did nothing when tapped.
Samsung said the message was sent by mistake during testing and ensured customers that there will be no effect on their device.
A statement read: "This notification was confirmed as a message sent unintentionally during internal testing and there is no effect on your device.
"Samsung apologises for any inconvenience this may have caused to our customers and will work to prevent similar cases from occurring in the future."
