Google now requires two years of regular security patches for popular Android devices

The Google Pixel 3
Moving forward, Android manufacturers will need to provide a minimum of four updates during the first year of release, which equates to at least one patch every three months, and an unspecified number during the second year of release. Moreover, by the end of each calendar month, any vulnerability discovered over 90 days ago must be patched. This same rule is valid with newly-released devices, regardless of when they were announced.
These specifics can be found inside Google’s updated licensing agreement for the European Union and, while it’s likely that some small details may be changed, very similar terms are expected in other regions of the world.
