Samsung Galaxy A03 Core
How long will it last?
Our estimateSupported until November 2023 · Buy-by November 2021
Apple doesn't publish an end date, but iPhones have a consistent ~2-year update track record — on that basis the Galaxy A03 Core should be supported until around November 2023. Buying it today still gets you about -2.5 years of safe use (Apple's written legal minimum is 5 years).
