I noticed a clear stability gap between the two models in the current Bangladesh market. The Oppo A78 4G is still officially available, so its pricing remains relatively consistent across major retail shops and online platforms. Dealers are aligned with official distribution, which reduces unexpected price jumps.

In contrast, the Tecno Camon 19 Pro is now mostly seen in unofficial stock. Because of that, pricing varies depending on the seller, storage variant, and warranty terms. Some shops price it attractively to clear old inventory, while others charge more due to limited availability.

Long gaming sessions clearly separate these two. I played PUBG Mobile, Call of Duty Mobile, Free Fire, and tested Genshin Impact in warm, non-AC rooms. According to GSMArena, the Tecno Camon 19 Pro, powered by Helio G96 (12nm), delivered more stable frame consistency on balanced graphics in PUBG and CODM. It held performance longer before noticeable throttling.

As per GSMArena data, the Oppo A78 4G with Snapdragon 680 (6nm) handled casual gaming fine, but under heavier load, minor frame drops appeared sooner. However, it stayed slightly cooler and drained battery slower. For pure gaming muscle in this price segment, Camon feels stronger. For efficiency and comfort, Oppo feels safer.

Camera versatility is where the competition gets serious. The Tecno Camon 19 Pro uses a 64MP main sensor with a dedicated 2x telephoto lens, giving it a clear zoom advantage. Portrait shots look more natural thanks to real optical zoom.

On the other hand, the Oppo A78 4G features a 50MP main sensor. In daylight, it produces balanced colors and more controlled highlights. Night shots show slightly better noise management on Oppo, though both struggle in very low light. For zoom and creative shooting, Camon leads. For consistent, ready-to-share results, Oppo feels more dependable.

The Oppo A78 4G’s 6.43-inch 90Hz AMOLED panel delivers deeper blacks and richer contrast. Watching YouTube at night or browsing in dark mode clearly feels more premium and easier on the eyes. Outdoor visibility under direct sunlight also felt slightly stronger.

The Tecno Camon 19 Pro’s 6.8-inch 120Hz IPS LCD scrolls smoother due to higher refresh rate. However, it lacks AMOLED depth and contrast punch. For media lovers and indoor comfort, Oppo wins. For larger screen real estate and smoother scrolling, Camon offers an advantage.

Choose Oppo A78 4G if you want AMOLED quality, better speakers, stronger official support, and balanced everyday reliability. Pick Tecno Camon 19 Pro if gaming power and optical zoom matter more. For most regular Bangladeshi users, Oppo feels safer long term, while Camon targets performance-focused buyers.

Does Oppo A78 4G heat during gaming?
Yes, it warms up after 40 minutes of PUBG, but heat stays manageable and doesn’t throttle aggressively like some budget devices.

Are both phones good for 4G in Bangladesh?
Yes, both handle Grameenphone and Banglalink 4G well, though neither supports 5G network.

In my testing, yes. Helio G96 maintains steadier frame stability compared to Snapdragon 680 in longer sessions.

Oppo A78 4G lasted slightly longer in mixed use, especially standby and video streaming.

Is AMOLED really better than LCD here?
Yes. Oppo’s AMOLED looks richer and more comfortable indoors, especially at night.

Camon 19 Pro clearly wins due to its dedicated 2x telephoto lens for sharper portrait and zoom shots.
