If you've recently received a mysterious notification on your Samsung Galaxy device, you're not alone. The tech giant has blasted Galaxy phone users worldwide with a Find My Mobile push notification that simply says "1." That's it -- just "1." I personally got it on a Samsung Galaxy S8+ and a Galaxy A50S, and for both devices, clicking it did nothing. At least nothing that I could see: It didn't fire up the application and offer any explanation of what it could mean.
