Samsung Galaxy A90 5G
How long will it last?
Our estimateSupported until September 2023 · Buy-by September 2021
Apple doesn't publish an end date, but iPhones have a consistent ~4-year update track record — on that basis the Galaxy A90 5G should be supported until around September 2023. Buying it today still gets you about -2.8 years of safe use (Apple's written legal minimum is 5 years).

Frequently asked questions
How long will the Galaxy A90 5G get updates?
Support has ended. Samsung delivered two OS upgrades (Android 9 to Android 11) and about four years of security patches, finishing around late 2023.
Is the Galaxy A90 5G powerful?
For its era, yes. It used the flagship Snapdragon 855, making it noticeably faster than the Exynos and lower-Snapdragon chips in the rest of this lineup.
Does the Galaxy A90 5G still get useful 5G?
It supports early 5G bands, so coverage can be patchy on newer networks, and combined with the lack of updates it is best treated as a budget secondary device.
