Compare Samsung Galaxy A25 & Oppo A78 4G Latest Price in Bangladesh
Current positioning in local shops tells an interesting story. The Samsung Galaxy A25 holds a more stable retail presence because it is officially distributed in Bangladesh. That keeps dealer margins consistent and ensures proper brand warranty. Whether I checked large showrooms or trusted online stores, pricing felt structured and predictable.
The Oppo A78 4G, however, depends heavily on unofficial importers. Because of this, its price shifts depending on stock flow and seller strategy. In some areas, it looks competitively priced, while in others, the difference narrows unexpectedly.
Compare Gaming Performance of Samsung Galaxy A25 & Oppo A78 4G
After long gaming sessions in warm Dhaka rooms, the Galaxy A25 clearly pulls ahead. Its Exynos 1280 delivers stronger and more stable performance than the Snapdragon 680 in the Oppo A78 4G. PUBG Mobile runs smoother at higher settings, COD Mobile stays steadier over time, and Genshin Impact remains consistent longer before throttling. While the Oppo A78 4G stays cooler initially, it drops performance sooner, making the Galaxy A25 the better choice for gaming.

Camera specs may look similar, but real-world results tell a different story. The Galaxy A25’s OIS makes low-light and handheld shots noticeably better, with evening street photos appearing brighter and more stable.
