Oppo A78 5G
How long will it last?
Our estimateSupported until January 2026 · Buy-by January 2024
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the A78 5G should be supported until around January 2026. Buying it today still gets you about -0.4 years of safe use (Apple's written legal minimum is 5 years).

Frequently asked questions

No. The A78 5G uses a MediaTek Dimensity 700 with an HD+ screen, while the separate A78 4G has a Snapdragon 680 and an AMOLED screen. They are different phones despite the shared name.
Can I use the A78 5G in the US?
It is not sold via official US retail. An imported unit works as an unlocked phone, but verify 5G band compatibility with your carrier first.

Oppo has not published specifics. Expect roughly 2 Android upgrades and security patches into early 2026 based on its budget-class pattern.
