Perhaps it was. I wasn't aware of Stagefright.
Well, it was really much to do about nothing. While technically affecting a bunch of different versions, the actual number of vulnerable phones/versions was actually rather small. And the exploit was found by a security firm, not an actual malicious app in the wild. Granted, I think the best thing to come out of this was that the somewhat overexagerated response to the exploit lead to Google and the OEMs commiting themselves to far more frequent security updates.... taking a page out of Microsoft's book.
Before, if there was a security patch, most people would have had to wait until the next full or minor version OTA from their OEM.... so 'Yea, Stagefright!'
