I have always been happy with Black Market, good products and good prices. But this phone has not been checked, it has problems and shuts down without warning. A pity, the Oppo brand is usually very good.

The Oppo A78 5G made its debut in early 2023, bringing 5G to everyday users without making a fuss about it. Now two years on, it remains a solid choice for anyone seeking reliable performance, straightforward features, and a modern design that doesn’t overcomplicate things. If you like tech that just works, the A78 5G keeps things refreshingly simple without feeling behind the curve.
Key features:The Oppo A78 5G is ideal for students, commuters, or anyone wanting effortless day-to-day performance and dependable 5G connectivity. It’s especially well-suited for those who want a fuss-free Android experience, prefer a readable LCD display, or just need a pre-owned device that handles messaging, social media, and streaming without drama. If you’re choosing between this and fancier alternatives, note that flagship features like AMOLED displays or ultra-wide cameras are missing—but sometimes simple really is best.
Pros & Cons:| Pros | Cons |
|---|---|
| Reliable 5G chipset for speedy browsing and downloads. | No AMOLED display—just an LCD, so blacks aren’t as deep. |
| Clean Android 13 OS shipped out of the box. | Basic camera setup, with no ultra-wide or telephoto lens. |
| 90Hz refresh rate keeps the screen looking smooth. | Build is all-plastic—very practical, but not exactly “premium”. |
Going for a refurbished Oppo A78 5G means less e-waste and a second chance for tech that still has life left in it. Every smartphone from Back Market is tested, cleaned, and checked against our quality standards—because “pre-owned” shouldn’t mean “worn out”. It’s circular tech made practical.
