Every Galaxy phone has an update window, and one day it closes. Samsung announces a set number of years of updates for each model, and when that period ends the phone stops getting new Android versions and then stops getting security patches too. Nothing breaks on that day. The phone keeps working exactly as it did the day before. But the question that follows is a real one: what do you do now?
