Samsung Galaxy J7 Duo (2018)
How long will it last?
Our estimateSupported until April 2021 · Buy-by April 2019
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Galaxy J7 Duo (2018) should be supported until around April 2021. Buying it today still gets you about -5.2 years of safe use (Apple's written legal minimum is 5 years).
