Samsung Galaxy A31
How long will it last?
Our estimateSupported until April 2024 · Buy-by April 2022
Apple doesn't publish an end date, but iPhones have a consistent ~4-year update track record — on that basis the Galaxy A31 should be supported until around April 2024. Buying it today still gets you about -2.1 years of safe use (Apple's written legal minimum is 5 years).
