"Already patched" isn't really as meaningful on Android as it is on, e.g., iOS where the average user can expect to (and frequently does) update their operating system.

How many phones are still vulnerable to StageFright?

The bug appears only on stock devices which are commonly updated. OEMs provide their own lock screens which aren't vulnerable.

So in this case "patched" is pretty meaningful.

How do you know they aren't vulnerable ;)
