Does anyone know how strict is the Google two year update policy for Nexus? It's clear they won't do major releases (such as Android 7.0) for old phones. However, what about critical security updates? For example, if something as bad as Stagefright was discovered, would Google do nothing for all the older Nexus phones out there? Or would something like that be a special exception to the rule?

That's from the date of initial introduction. The relevant number is 18 months from the date you bought it.

Seems neither Google nor Apple do special exceptions. Out is out. Might install Cyanogen on my Nexus 5 but have to toss my iPhone 4s.
