I think this is Samsung's call. As of what I understood, they will partner up with carriers to push security updates without going through carrier verification process that takes SOOOO LONG!! I'm pretty sure they will update all devices since the S3, but if they don't it doesn't really matter because you just have to turn off MMS Auto-Retrieve and thats it, the big bad wolf "Stagefright" is neutralized just like that. I know it's a major flaw, but the fix is so simple and anybody can do it. Social media made such a big fuss over nothing really, thanks to Zimperium for finding the exploit and telling the right people before this got in the wrong hands. Reming me of the Heartbleed, the internet exploit that would be so devastating it would change how we surf, 24 hours later, most websites had the exploit patched and nothing bad really happened.
Now, Apple has a situation on their hand over official applications being injected with malicious code that could pretty much forward all communication including keylogs, sms, phone calls, bank information and much more to hackers that are just waiting for the right naive victime...now thats a problem because it's happening right now.
