Samsung Galaxy A21s
How long will it last?
Our estimateSupported until June 2023 · Buy-by June 2021
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Galaxy A21s should be supported until around June 2023. Buying it today still gets you about -3.0 years of safe use (Apple's written legal minimum is 5 years).
