Oppo A78 5G : Oppo has taken a practical approach with the A78 5G, creating a phone that prioritizes reliability over flashiness. This device targets buyers who need solid everyday performance and 5G connectivity without complicated features or premium pricing. After living with the A78 for daily tasks, it becomes clear that sometimes the best phone is simply one that doesn’t get in your way.
Dependable Performance
The MediaTek Dimensity 6020 chipset provides steady performance for typical smartphone usage. Apps launch at reasonable speeds, social media scrolling stays smooth enough, and basic multitasking happens without excessive frustration. This isn’t the fastest processor available, but it handles daily activities like messaging, browsing, and streaming without major complaints.
Gaming works within reasonable limits. Casual titles run perfectly, while demanding games like BGMI operate at lower settings with playable frame rates. The phone stays reasonably cool during gaming, getting slightly warm without becoming uncomfortable. Mobile gaming enthusiasts should look elsewhere, but occasional players will find the experience acceptable.
The 8GB RAM configuration includes virtual expansion borrowing up to 8GB from storage, helping keep background apps ready. The 128GB storage handles most users’ needs, though heavy media downloaders might wish for more space. Memory management works reasonably well, reducing the need to constantly reload apps.

Practical Display
The 6.56-inch LCD screen running at 90Hz provides adequate visual quality for the price. Colors appear reasonably natural, and the higher refresh rate makes scrolling feel smoother than basic 60Hz displays. Brightness levels work fine indoors and manage outdoor visibility in most conditions, though bright sunlight requires some shading.
The HD+ resolution won’t impress pixel-peepers, but everyday users likely won’t notice during normal use. Videos look acceptable, text remains readable, and the screen serves its purpose without trying to be something it’s not.

The side-mounted fingerprint sensor works reliably with quick recognition. Its position on the power button feels natural and accessible. Face unlock functions adequately when lighting cooperates.
Camera for Daily Snapshots
The 50MP main camera captures decent photos in good lighting. Colors come out reasonably accurate, and sharpness is acceptable for social media posting. The AI processing helps without going overboard, keeping images looking relatively natural rather than artificially enhanced.
Portrait shots create adequate background blur for casual photography. The edge detection stumbles occasionally with tricky subjects, but results generally work fine for Instagram or WhatsApp sharing. The 2MP depth sensor contributes little beyond padding the spec sheet.
Low-light photography shows the budget limitations. Night mode improves things by merging multiple shots, but you’ll still see noise and softness that premium phones avoid. These photos work for quick sharing but won’t win photography contests. The 8MP selfie camera handles video calls and self-portraits competently when lighting cooperates.
Video tops out at 1080p 30fps with basic stabilization—fine for casual clips but nothing special.
Battery That Goes the Distance
The 5000mAh battery delivers reliable all-day performance. Regular use involving social media, messaging, some photos, and video watching leaves power remaining by bedtime. Even heavier daily use generally gets you through without hunting for chargers.

The 33W charging speed feels adequate—not the fastest available but reasonable enough. A full charge takes around 70 minutes. A quick 30-minute charge provides several hours of usage for those rushed mornings when you forgot to plug in overnight.
Simple Design
The plastic build keeps weight and cost down. The glossy back catches light nicely in Glowing Black or Glowing Purple finishes, though fingerprints appear quickly. The construction feels solid enough without any creaking or flex.
At 188 grams, the phone feels comfortable during extended use. The size remains manageable for one-handed operation most of the time. IPX4 splash resistance offers basic protection against light rain and spills.
