The Oppo A78 Premium 5G and Vivo V29 are two of the most talked-about mid-range 5G smartphones in India’s competitive segment. Both brands are known for offering stylish designs, dependable performance, and great cameras at affordable prices. While the Oppo A78 Premium 5G focuses on practical efficiency, the Vivo V29 leans toward camera excellence and premium design. As of September 2025, these two devices continue to attract buyers who want solid all-around performance without spending flagship money.
Design and Build Quality
The Oppo A78 Premium 5G carries a lightweight design with a sleek, glossy finish and smooth edges that make it comfortable to hold for long hours. Its dual-ring rear camera setup adds to its visual appeal, and at just around 188 grams, it feels ergonomic and pocket-friendly. The polycarbonate body ensures durability, and the side-mounted fingerprint sensor offers quick access.
In contrast, the Vivo V29 steps up with a 3D curved glass back, a metal frame, and the brand’s unique Aura Light ring at the rear that enhances portrait lighting in dim conditions. It feels more premium, has better grip, and resists fingerprints thanks to its matte glass surface.
Verdict: The Vivo V29 clearly feels more luxurious in hand, while the Oppo A78 Premium 5G scores higher on practicality and lightweight handling.
Display and Visual Experience
When it comes to the display, both phones deliver sharp visuals, but there’s a noticeable difference in smoothness and brightness.
