Google's software update life cycle policy for Nexus and Pixel devices is that: 1. They "get Android version updates for at least 2 years from when the device became available on the Google Store. After 2 years, we can't guarantee additional updates." 2. They "get security patches for at least 3 years from when the device first became available, or at least 18 months from when the Google Store last sold the device, whichever is longer."

Are there any manufacturers that give their devices longer life cycles than Google gives Nexus and Pixel devices when it comes to Android version updates, security patches, or both?
In addition, if possible, please tell me how rapidly these manufacturers provide Android version updates and/or monthly security updates, in comparison to how rapidly Google provides them to Nexus and Pixel devices.
