Oppo A77 4G Price In Bangladesh 2025 & Full Specs

The Oppo A77 4G is one of the mid-range smartphones from Oppo, designed to provide a balance between style, performance, and affordability. In Bangladesh, where the smartphone market is highly competitive, the Oppo A77 4G stands out with its slim design, decent performance, and long-lasting battery life. This review will cover everything you need to know, including its price, features, pros, cons, and whether it’s worth your money.

1. Oppo A77 4G Price in Bangladesh

In Bangladesh, the Oppo A77 4G is priced around BDT 20,000 – BDT 23,000, depending on the retailer and ongoing promotions. For this price, you get the 4GB RAM and 64GB storage variant, which is the most common version available in the country.

This price places the Oppo A77 4G squarely in the budget-to-mid-range category, competing directly with devices from Realme, Xiaomi, and Samsung. For many Bangladeshi consumers, this price range is considered ideal for daily use smartphones that deliver both performance and reliability without breaking the bank.

2. Design and Build Quality

One of the strongest aspects of the Oppo A77 4G is its design. Oppo has always emphasized aesthetics, and this device is no exception.

Dimensions: 163.8 x 75.1 x 7.99 mm
Weight: 187 grams
Material: Glass front, plastic frame, and plastic back

The phone is slim and lightweight, making it comfortable to hold for extended periods. The matte finish on the back prevents fingerprints, and the overall build feels sturdy despite being primarily plastic. It comes in two elegant color options: Sunset Orange (with a leather-like texture) and Sky Blue, both of which appeal to younger buyers.

Although the device doesn’t boast a premium metal frame or glass back like flagship models, it provides a sleek and stylish look that competes well within its segment.

3. Display Quality

The Oppo A77 4G features a 6.56-inch IPS LCD with a 720 x 1612 pixel resolution (~269 ppi density). While not Full HD, the display is vibrant and offers decent brightness for everyday use.

Screen Size: 6.56 inches
Resolution: HD+ (720 x 1612 pixels)
Refresh Rate: 60Hz
Peak Brightness: Up to 600 nits

The screen is ideal for regular activities like browsing, watching YouTube, or scrolling through social media. The colors are natural, though not as vivid as AMOLED panels. Under bright sunlight, visibility is satisfactory, but it lacks the punch of higher-end displays.

For a device in this price range, the display performs adequately. However, if you’re a user who prioritizes Full HD resolution or high refresh rates, you might find this display somewhat basic.

4. Performance and Hardware

The Oppo A77 4G is powered by:

Processor: MediaTek Helio G35 (12nm)
CPU: Octa-core (4×2.3 GHz Cortex-A53 & 4×1.8 GHz Cortex-A53)
GPU: PowerVR GE8320
RAM: 4GB
Storage: 64GB (expandable via microSD up to 1TB)

The Helio G35 is an entry-level gaming chipset that handles day-to-day tasks smoothly. For typical use like calling, messaging, social media, and video streaming, the phone performs reliably. However, it is not designed for heavy gaming or multitasking. Games like Free Fire or PUBG Mobile will run, but only on lower settings with occasional frame drops.

In benchmarks, the phone scores modestly compared to competitors, but its focus is on efficiency and stability rather than raw power.

5. Software Experience

The Oppo A77 4G runs on ColorOS 12.1 based on Android 12, offering a smooth and intuitive user experience.

Key features of ColorOS include:

Smart Sidebar: Quick access to apps and tools.
FlexDrop: Multi-tasking window feature.
Customizable themes and always-on display (limited features).

The interface is user-friendly and visually pleasing, though it does come with some pre-installed apps (bloatware), which can be uninstalled if unwanted.

6. Camera Performance

The camera setup on the Oppo A77 4G is simple but capable for its price:

Rear Camera:

50MP primary sensor (wide, f/1.8)
2MP depth sensor (f/2.4)
Features: LED flash, HDR, panorama
Video: 1080p at 30fps

Front Camera:

8MP selfie camera (f/2.0)
Video: 1080p at 30fps

In daylight, the 50MP primary camera captures detailed and well-lit photos with accurate colors. The depth sensor helps with portrait shots, though edge detection isn’t perfect.

In low-light conditions, images suffer from noise and loss of detail, as expected in this category. The front camera produces decent selfies with natural skin tones under good lighting but struggles in dim environments.

For video, stabilization is basic, so handheld shots can appear shaky.

7. Battery Life and Charging

Battery performance is one of the Oppo A77 4G’s strongest selling points.

Battery Capacity: 5000mAh
Charging Speed: 33W SuperVOOC fast charging

The large battery easily lasts a full day of moderate to heavy use, and light users can stretch it to nearly two days. The 33W fast charger included in the box charges the phone from 0% to 50% in about 30 minutes, which is excellent at this price point.

8. Connectivity and Other Features

The Oppo A77 4G supports:

4G LTE (no 5G support)
Dual SIM
Wi-Fi 802.11 b/g/n/ac
Bluetooth 5.0
USB Type-C port
3.5mm headphone jack
Side-mounted fingerprint scanner & face unlock

Missing features include NFC and 5G, but for many Bangladeshi consumers, 4G connectivity remains sufficient for daily use.

9. Real-World User Experience

Feedback from users in Bangladesh indicates that the Oppo A77 4G delivers:

Smooth day-to-day performance
Excellent battery life
Stylish, modern design
Reliable cameras for casual photography

However, users also note:

The display resolution could have been better (Full HD expected in 2025 mid-range).
Not ideal for heavy gaming or multitasking.
No 5G support, which might be a limitation in the near future.

10. Pros and Cons

Pros:

Affordable pricing in Bangladesh (BDT 20,000 – BDT 23,000)
Stylish and slim design
5000mAh battery with 33W fast charging
Clean and intuitive ColorOS 12.1
Decent main camera with 50MP sensor
Expandable storage and headphone jack

Cons:

Only HD+ resolution (not Full HD)
No 5G connectivity
Average gaming performance
Low-light camera performance could be better

11. Final Verdict

The Oppo A77 4G is an excellent choice for users seeking a budget-friendly smartphone with a premium look, long battery life, and dependable performance for daily use. While it lacks some modern features like 5G and a Full HD display, it compensates with its durability, efficient software, and excellent battery life.

For Bangladeshi buyers in the BDT 20,000 – BDT 23,000 range, the Oppo A77 4G offers great value, especially for students, professionals, and casual smartphone users. If you’re not a heavy gamer and prioritize reliability and style, this phone deserves strong consideration.
