What surprised me most during my market survey was how differently these two phones behave in real Bangladeshi retail conditions. The Oppo A78 4G benefits from official distribution, so its pricing remains comparatively structured and predictable across large showrooms and authorized outlets. Retailers were confident about warranty coverage, and stock availability was consistent in most places I visited.

The Motorola Moto G73 tells a different story. Since it’s largely unofficial in Bangladesh, pricing depends heavily on importer batches and individual shop margins. I noticed noticeable variation between stores, especially in smaller markets and availability also isn't guaranteed at all times.

Raw power separates these two quickly. The Oppo A78 4G’s Snapdragon 680 handles PUBG and CODM on medium settings, but long sessions bring frame drops and mild heating. It’s fine for casual gamers, not competitive ones.

The Motorola Moto G73’s Dimensity 930 is clearly stronger. PUBG runs smoother on higher settings with better frame stability and less aggressive throttling. In sustained gaming, Moto feels more confident and consistent in this price range.

Both phones performed reliably on Grameenphone, Banglalink, and Robi networks. The Oppo A78 4G delivers stable 4G LTE for browsing and calls, but peak-hour speed fluctuation was noticeable in crowded areas.

The Moto G73 held signals more consistently indoors and during congestion. It also supports 5G, offering future readiness as rollout expands. Wi-Fi stability was slightly better on Moto when moving across rooms. Overall, Moto feels more future-proof for connectivity.

Both phones use 50MP main cameras, but the Motorola Moto G73 adds an 8MP ultrawide camera, giving it more flexibility. The Oppo A78 4G delivers brighter, more vibrant daylight photos, while Moto’s colors look more natural. In low light, Oppo tends to over-process, whereas Moto retains better detail. Video stabilization and ultrawide shots are stronger on the Moto G73, making it the more consistent overall camera.

Visual experience depends on what you prioritize. Oppo A78 4G’s 6.43-inch AMOLED panel produces deeper blacks and richer colors. Watching movies indoors feels more immersive and premium.

The Motorola Moto G73’s 6.5-inch IPS LCD with 120Hz refresh rate delivers smoother scrolling and UI transitions. Under harsh outdoor sunlight, readability felt marginally better on the Moto. If cinematic color depth is your priority, Oppo wins. If smoother navigation and outdoor clarity matter more, Moto stands stronger.

Go for Moto G73 if performance, smoother gaming, multitasking strength, ultrawide camera, and 5G readiness are your priorities. Choose Oppo A78 4G if AMOLED visuals and ultra-fast charging matter most. Power users will benefit more from Moto’s stronger overall hardware.
