Just got the latest Security Patch for my S6. Ran two Stagefright detctor programs, and the vulnerability still exists. What the heck Verizon? This issue was discovered last April.
Same here - just updated S6 with G920VVRU4BOG7 today (Sep 29) and three different detectors still say it's there.
Zimperium's Stagefright Detector tells which ones are there and which are cleared. It shows CVE-2015-3864 is still in the red as vulnerable.
Please, Verizon - please send the fix for this!
