Samsung Galaxy A03
How long will it last?
Our estimateSupported until November 2024 · Buy-by November 2022
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Galaxy A03 should be supported until around November 2024. Buying it today still gets you about -1.5 years of safe use (Apple's written legal minimum is 5 years).

Frequently asked questions
How long will the Galaxy A03 get updates?
The A03 shipped with Android 11 in late 2021 and received updates up to Android 13, but its security support has now ended. It no longer receives patches.
What chipset does the Galaxy A03 use?
It uses the Unisoc T606, an entry-level 12nm chip. It is adequate for messaging and browsing but struggles with heavier apps and games.
Is the Galaxy A03 still worth buying?
Not really for daily use in 2026. With support ended and modest performance, it only makes sense as a very cheap spare or first phone.
