You asked which Android phones get five years of security updates? Directly from Google, only the Pixel 6 and up, most likely in reaction to Apple's better support policies. Other manufacturers? You have to research it because it varies: https://www.androidauthority.com/phone-update-policies-16586...
Ideally Google would mandate a minimum number of years for both feature and security updates that matches theirs of three and five, respectively. Having said that, these really are wasting assets thanks to storage wearing out, but that's true of all phones, regardless of manufacturer.
