Design and Build Quality

One of the most appealing aspects of the Oppo A57 4G is its design. Despite being a budget device, Oppo has put noticeable effort into making it look and feel premium. The phone is slim and lightweight, weighing about 187 grams with a thickness of 7.99mm, making it comfortable to hold for long periods.

Oppo’s “Glowing Design” philosophy is evident here. The phone comes in stylish color variants such as Glowing Green and Glowing Black. The back panel has a shimmering finish that resists fingerprints and scratches, which is a big plus for users who don’t want to constantly wipe their phones clean.

The rear camera module is rectangular with slightly raised lenses, giving it a modern aesthetic. The side-mounted fingerprint scanner doubles as a power button, which feels both natural and convenient. The placement of volume rockers and SIM tray is ergonomically friendly as well.

For a phone priced under 20k BDT, the Oppo A57 4G manages to deliver a premium in-hand feel that rivals more expensive devices.

Display Quality

The Oppo A57 4G sports a 6.56-inch IPS LCD panel with a resolution of 720 × 1612 pixels (HD+). While this isn’t the sharpest display compared to Full HD+ competitors, Oppo has optimized brightness and color reproduction well.

Key highlights:

• Brightness: Up to 600 nits (peak), making it usable outdoors in sunlight.
• Refresh rate: Standard 60Hz, which is acceptable in this price range but less fluid than 90Hz competitors.
• Color reproduction: Vivid and slightly oversaturated, appealing to casual users who like punchy visuals.
• Bezels: Slim for the price, although the chin at the bottom is still noticeable.

Watching videos on YouTube, Netflix, or Facebook feels enjoyable thanks to Oppo’s dual stereo speakers, which enhance the multimedia experience. The sound quality is loud, clear, and balanced – a rare find in this segment.

Performance and Hardware

At the heart of the Oppo A57 4G lies the MediaTek Helio G35 processor paired with 4GB RAM and 64GB storage. While this chipset is not built for heavy gaming, it handles everyday tasks smoothly.

Everyday Performance

• Multitasking between social media apps, messaging, and web browsing is fluid.
• Oppo’s RAM Expansion feature allows the system to borrow storage (up to 4GB) and use it as virtual RAM, effectively simulating 8GB RAM performance in lighter tasks.
• Casual apps like WhatsApp, TikTok, Instagram, and YouTube run without noticeable lag.

Gaming Performance

• Games like PUBG Mobile, Free Fire, and Call of Duty run on low to medium graphics settings.
• The phone tends to heat slightly during long gaming sessions, but not to an uncomfortable level.
• It’s clear that this phone is designed for casual gaming rather than competitive-level performance.

Storage

With 64GB internal storage, users may find it slightly limited if they install many apps or store videos/photos. However, the dedicated microSD slot allows expansion up to 1TB, solving this limitation.

Software Experience

The Oppo A57 4G runs on ColorOS 12.1 based on Android 12, which is one of the most feature-rich custom Android skins available.

Some standout features:

• FlexDrop: Mini window multitasking feature.
• Three-finger screenshot: Intuitive and handy.
• System theme customization: Adjust colors, icons, and wallpapers easily.
• RAM Expansion: Adds up to 4GB virtual RAM.
• AI System Booster: Manages background apps for smoother performance.

The UI feels smooth and polished, with thoughtful animations. Oppo also focuses on privacy and security features, such as app permissions management and private safe storage.

Camera Performance

Oppo has always prioritized cameras, and while the Oppo A57 4G isn’t a photography powerhouse, it delivers respectable results for the price.

Rear Camera

• 13MP main sensor: Captures decent photos in good lighting. Colors are natural with moderate detail.
• 2MP depth sensor: Helps with portrait shots, though edge detection can sometimes be soft.

Front Camera

• 8MP selfie shooter: Produces bright selfies with Oppo’s signature beauty filters. Ideal for social media sharing.

Camera Features

• Night Mode (basic, but useful for low-light shots)
• HDR for balanced contrast
• AI Scene Enhancement
• Portrait Mode with adjustable blur

Video recording maxes at 1080p 30fps from both front and rear cameras. Stabilization is limited, so handheld footage may appear shaky.

For casual users who mainly capture social moments, the camera system is more than adequate.

Battery Life

The 5000mAh battery is one of the biggest strengths of the Oppo A57 4G. Combined with its power-efficient Helio G35 processor and HD+ display, the phone can easily last a day and a half to two days on moderate use.

Key Highlights:

• Screen-on time: Around 7–8 hours depending on usage.
• Charging: The phone supports 33W SuperVOOC fast charging, which is extremely rare at this price. It charges the battery from 0 to 50% in about 30 minutes, and a full charge takes around 70–75 minutes.
• Power Saving Modes: Oppo’s software includes multiple modes to extend battery life further.

This makes the phone ideal for users who are always on the move and can’t afford frequent charging.

Connectivity and Extras

• Dual SIM with dedicated microSD slot (no hybrid compromise).
• 4G LTE only – no 5G support, but this is acceptable in this price bracket in Bangladesh.
• USB Type-C (welcome feature compared to older micro-USB budget phones).
• Dual stereo speakers – great for media and calls.
• 3.5mm headphone jack – still included for wired earphone lovers.
