Design and Build Quality
Premium Look on a Budget
One of Oppo’s strongest points has always been design, and the Oppo A78 5G continues that tradition. Despite being a budget device, the phone looks surprisingly premium. The flat edges, glossy back panel, and clean camera layout give it a modern aesthetic that easily competes with more expensive smartphones.
The phone feels comfortable in hand thanks to its slim profile and well-balanced weight. It is lightweight enough for one-handed use, yet solid enough to not feel cheap.
Build Material
The Oppo A78 5G uses a plastic back and frame, which is expected at this price point. However, Oppo has done an excellent job with the finish. The matte texture reduces fingerprint smudges, and the overall build quality feels sturdy.
Color Options
The device is available in attractive color variants that add to its visual appeal. These colors are designed to catch light in subtle ways, giving the phone a premium glow.
Ergonomics
The power button, which also doubles as a fingerprint scanner, is conveniently placed on the side. Volume buttons are easy to reach, and the phone does not feel bulky despite its large display.
Display Quality

Refresh Rate Advantage
One of the standout features of this device is its high refresh rate. Scrolling through apps, browsing menus, and switching between applications feels noticeably smoother compared to standard 60Hz displays.
Resolution and Sharpness
While the display offers good brightness and color reproduction, the resolution is not the highest in its segment. Text and images appear clear enough for everyday use, but sharp-eyed users may notice that it is not as crisp as Full HD panels.
