Okay so after installing 5.1.1 which has the patch included I tested to see if my z3 is vulnerable and it came back saying everything wad good. I checked again like 2 minutes ago after updating the SF detector app and it now says I'm "Vulnerable" again. Why? What is going on now? This doesn't make sense. It's CVE-2015-3864 everything else checks out. This is starting to make me very concerned.
Yes this is really starting to get annoying. I actually got a random sms message sent to me the other day by an Important number and I quickly deleted it. Of course I had my sms auto download turned off it really scared me.
