Samsung Galaxy J4+ (2018)
How long will it last?
Our estimateSupported until October 2021 · Buy-by October 2019
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Galaxy J4+ (2018) should be supported until around October 2021. Buying it today still gets you about -4.7 years of safe use (Apple's written legal minimum is 5 years).
