Design and Build: A Stylish and Practical Approach

Oppo never disappoints when it comes to design, and the A40 is no exception. It carries a modern aesthetic with clean lines and a polished finish that gives the device a premium feel even though it is priced affordably.

The device is slim, measuring around 7.8mm in thickness, and it weighs just about 177 grams. That makes it lightweight and comfortable to handle even during extended usage. Oppo uses a polycarbonate back with a matte finish, ensuring fewer fingerprints and smudges. Despite using plastic instead of glass, the phone does not feel cheap at all. In fact, it strikes a nice balance between durability and style.

Color options include Crystal Silver and Midnight Black — both subtle yet attractive choices that give users a bit of personality without being flashy.

Display: Visual Delight for Everyday Users

The Oppo A40 sports a 6.56-inch IPS LCD display with a resolution of 1612 x 720 pixels. While some might have expected an AMOLED panel, considering the price point, the LCD here does an admirable job.
Colors are vivid, viewing angles are solid, and the maximum brightness is sufficient for outdoor use under direct sunlight.

Perhaps the most impressive feature of the display is its 90Hz refresh rate. This means scrolling through menus, social media, or websites feels smoother compared to standard 60Hz panels. For people upgrading from older devices, this will make the device feel noticeably more responsive and modern.

The bezels are reasonably thin, giving the phone a contemporary look, and there is a small punch-hole cutout for the front camera, which is less intrusive compared to traditional notch designs.

Performance: Capable for Daily Life and Light Gaming

Under the hood, the Oppo A40 is powered by the MediaTek Dimensity 6020 chipset. Built on a 7nm architecture, this processor offers a good blend of performance and energy efficiency, making it ideal for everyday use.

Paired with 8GB of RAM and 128GB of internal storage (expandable via microSD card), the Oppo A40 handles typical tasks effortlessly. Opening multiple apps, browsing the web, streaming videos, and switching between apps happens without noticeable lags.

Light and moderate gaming are also manageable. Popular titles like PUBG Mobile, Asphalt 9, and Call of Duty: Mobile run smoothly on medium settings. While it’s not designed for hardcore gaming, casual gamers will find it more than capable.

The RAM expansion technology allows users to virtually extend RAM by up to 8GB, improving multitasking even further. This is particularly helpful for users who like keeping lots of apps open simultaneously.

Camera System: Simplicity That Works

Oppo has equipped the A40 with a dual-camera setup on the rear:

  • 50MP Main Camera (f/1.8 aperture)
  • 2MP Depth Sensor

For selfies, there’s an 8MP front-facing camera housed in the punch-hole cutout.

Rear Camera Performance

The 50MP sensor captures sharp, detailed images in good lighting conditions. Colors are rendered naturally, and dynamic range is quite impressive for a phone in this price range.
Portrait shots also benefit from decent edge detection, thanks to the 2MP depth sensor.

In low-light conditions, the camera holds up reasonably well if you use the Night Mode feature. There is some noticeable noise, but the results are still perfectly usable for social media and casual photography.

Video recording supports up to 1080p resolution at 30fps. Video stabilization isn’t flagship-level, but it’s sufficient for casual videos and vlogging needs.

Front Camera Performance

The 8MP selfie shooter does a good job capturing natural skin tones and decent detail. Oppo’s AI Beautification is available for those who like a little extra polish on their selfies.

For video calls and selfies, the A40 is more than adequate.

Battery Life: Built to Last Through the Day

One of the Oppo A40’s strongest points is its battery performance. The device packs a 5000mAh battery, a generous size that promises full-day usage without breaking a sweat.

In real-world scenarios, this translates to around 6-7 hours of screen-on time. Whether you’re browsing, streaming videos, playing casual games, or attending online classes, the A40 easily makes it through a day with 20-30% battery left.

The phone supports 33W SUPERVOOC fast charging, allowing the device to charge from 0% to around 50% in just about 28 minutes. A full charge takes slightly under an hour and fifteen minutes.
For users who are always on the go, this is a significant advantage.

Software: ColorOS Experience Refined

The Oppo A40 runs ColorOS 14 based on Android 14 right out of the box. Over the years, ColorOS has transformed from a cluttered UI into one of the more refined and intuitive Android skins.

ColorOS 14 focuses on a clean design, smoother animations, and thoughtful features like Smart Sidebar, Three-Finger Screenshot, Game Assistant, and more. Privacy controls have been enhanced, and the system feels generally lighter compared to older versions.

There is some pre-installed bloatware, but most unwanted apps can be easily uninstalled.

One important point is that Oppo promises at least two years of major Android updates and three years of security patches for the A40, which is reassuring for long-term buyers.

Audio and Connectivity: Practical and Reliable

The Oppo A40 features a single bottom-firing speaker. While it won’t blow you away, it gets reasonably loud without much distortion at high volumes. There is also a 3.5mm headphone jack — a feature that’s becoming increasingly rare but still highly appreciated by many users.

Connectivity options are comprehensive:

  • 5G support with multiple bands
  • Wi-Fi 5
  • Bluetooth 5.3
  • USB Type-C port
  • GPS, GLONASS, GALILEO support

Call quality is excellent, and mobile network performance is stable even in areas with spotty coverage.

Fingerprint unlocking is handled by a side-mounted sensor integrated into the power button. It’s quick and accurate. Face unlock is also available and works well in good lighting conditions.

Who Should Buy the Oppo A40?

The Oppo A40 targets a broad range of users:

  • First-time smartphone users who want a modern device without spending too much.
  • Students and professionals who need reliable performance, good battery life, and a decent camera setup.
  • Casual gamers who enjoy light to moderate gaming without needing flagship-level graphics.
  • Older users who prefer a simple, smooth, and easy-to-use smartphone without unnecessary complexity.

In short, if you’re looking for a device that handles everyday tasks with style and doesn’t empty your wallet, the Oppo A40 deserves serious consideration.

Oppo A40 Limitations: Points to Consider

No smartphone is perfect, and the Oppo A40 is no different.
Here are a few areas where compromises were made:

  • No AMOLED Display: IPS LCD is good, but AMOLED would have been better at this price point.
  • No Ultra-Wide Lens: Only a main sensor and depth sensor are available; no flexibility for ultra-wide shots.
  • No Stereo Speakers: Media consumption is decent, but stereo sound would have elevated the experience.

However, considering the price and target audience, these drawbacks are understandable and forgivable.

Final Verdict: A Smart Choice for 2025

The Oppo A40 delivers a lot for its asking price. Solid performance, clean software, stylish design, dependable battery life, and a capable main camera — all packed into a slim and lightweight body.

For people who want a reliable phone without entering the highly competitive ₹30,000+ category, the A40 stands out as an excellent option.
It’s ideal for daily usage, casual gaming, social media, photography, and even basic professional needs. Oppo has once again proven that you don’t need to spend a fortune to get a beautiful, functional smartphone.

If you want a phone that does the job without any unnecessary complications, the Oppo A40 could very well be your perfect companion for the coming years.
