Samsung smartphone users got a surprise Thursday morning as a random notification was sent to the mobile tracking application.

The notice received by a large number of users was dedicated to the application "Find My Mobile" of Samsung, and the number "1" appeared twice in the notice, without any other information.

Once clicked, the notification disappeared, and some users reported on Twitter that it had consumed a large portion of the battery life.

According to Samsung, the "1" was mistakenly sent to a number of Galaxy phones as part of an "internal test".

"The notice was inadvertently sent to a limited number of Galaxy devices," the company said in a statement. "We can assure our users that this notification does not affect their devices in any way."

"We sincerely apologize to our customers for any inconvenience this has caused, and we will ensure that no similar incident occurs in the future," she added.

The South Korean tech giant recently released a folded phone, the Galaxy Z Flip, and told people on social media that the new device was also affected by the notification accident, as well as some of the new Samsung S series and tablets.
