If you own a Samsung Galaxy smartphone, chances are that earlier today you received a weird notification on your phone via the Find My Mobile app. The notification only read "1", followed by another "1" that was right below it, and that was it. The moment you would tap on the notification, it would do nothing but close the shade altogether.

Normally, something like this could easily be ignored, but this was not an isolated issue, to begin with. Users all over the internet started reporting this incident on a variety of forums. Turns out, even we received the said notification on a number of different Galaxy devices. Below is a screenshot of the notification.
