Know, you are talking about an exploit that could be affecting 60% of Android phones...
No, I'm not.
I was responding to a comment about the general state of Android and iOS security updates, not anything specific to this security vulnerability.
In general, if you have an iOS device and Apple decides not to fix a security problem on your phone, it's most likely not going to be fixed.
In general, if you have an Android device and both Google and your vendor decide not to fix a security problem on your phone, you might have a chance to get it fixed by other means. It's not a sure thing, it's not without risk, and you might not be entirely happy with the end result, but it works often enough that it's not a crapshoot.
Now, if you want to get into specifics, I don't know how many of the 60% of vulnerable devices might be able to take advantage of non-Google support, but it's far better than nothing.
