Asked this on Serious Kopitiam, couldn't get an answer, so ask here too.

On my Samsung, I received something that looked like a typical android system pop-up with the title "Flash SMS Message". The only options were "Cancel" and "Save".

Obviously I clicked "Cancel" but I'm at a total lost as to what it was. I tried googling but some of the sources I found indicated that a "Flash Message" should only be able to be sent by a govermental agency, and yet the message I received seemed to be some weird spam promoting MyTukar I think, which doesn't strike me as a "Govermental Agency"-approved message.

Thoughts?
