Expert point of view
The OPPO A3x 5G is a cost-effective smartphone that caters to the needs of users seeking a seamless performance along with a long-lasting battery life, all with the newest 5G technology. Besides, its beautiful design, large-screen display, and basic camera functions have made it a great option for Indian customers who need daily access to such a device at a reasonable price.
Design
The OPPO A3x 5G adopts a neat and modern A-series appearance: it has a design with flat edges and a back with a texture that makes it easier to hold and be less prone to showing fingerprints. OPPO's official website and advertisements talk up the phone's light and slim characteristics â it has a size of approximately 165.7 Ă 76.0 Ă 7.7â7.8 mm and a weight of around 186â187 g, which is quite pleasant in terms of weight for a phone with a 5,100 mAh battery. The back houses a compact camera island rather than a protruding multi-lens tower, which keeps the phone balanced on a desk. Build materials are polycarbonate (common in this segment) with reinforced cover glass claimed in OPPOâs spec sheet.

Design highlights OPPO calls out for the A3x include military-grade shock resistance tests and multiple liquid-resistance assurances â features aimed at buyers who want a more rugged everyday phone without paying for premium flagship durability. That makes the device feel like a practical, user-first offering rather than a fragile glass slab.
Display
A3x's major attribute is its 6.67-inch LCD display which has an HD+ resolution of 1604 Ă 720 (roughly 264 ppi) plus good refresh rate. The specs are not constant everywhere, and the OPPO's site for India proposes a 120 Hz ultra-bright version (1,000 nits peak brightness) that creates animations and scrolling that are very smooth and nice. This is in comparison with the standard 60 Hz panels. The panel also supports a high touch sampling rate (helpful for responsiveness in games and touch navigation).

Because itâs an LCD (not AMOLED), blacks arenât as deep but the display remains very usable outdoors thanks to the claimed peak brightness. The HD+ resolution keeps the GPU load light, which helps battery life and keeps the phone responsive while delivering acceptable sharpness for everyday tasks (social media, video streaming, browsing). In short: large, bright and smooth â optimized for longevity and efficiency rather than ultra-sharp pixel density.
Camera â Overview
The OPPO A3x 5G takes a modest, utility-focused approach to imaging. Itâs not trying to replace flagship camera mobile instead, it offers reliable, social-media-ready photos in good light and basic camera tools for everyday use. The official spec sheet lists a simple rear camera system highlighted by an 8 MP main sensor and a 5 MP front camera for selfies. There are software features and shooting modes to assist users, but you shouldnât expect heavy computational photography or multi-camera versatility like telephoto or high-resolution primary sensors.

Front Camera
The selfie unit is a 5 MP shooter with an f/2.2 aperture and a fairly wide field of view (around 78°). Itâs tuned for social posts and video calls rather than high-resolution portrait work. The front camera can create skin tones that are somewhat acceptable and detail good enough for Instagram and WhatsApp when there is a decent light source; in low light, the camera brings out the faces mainly through software and its own lighting techniques, but still, there will be noticeable image noise, unlike some midrange phones that use higher-resolution selfie sensors. The front camera video is usually limited to 1080p @ 30 fps, which is still sufficient for video calls.
Back Camera
The rear camera configuration is deliberate in its simplicity: what one sees is the principal sensor of 8 MP with the autofocusing capability and the usual wide-angle viewing angle. OPPO offers users the most common software tools â HDR, scene optimization and filters â to help them capture good pictures easily without needing to adjust settings manually. In bright outdoor conditions the main camera captures pleasingly exposed images with reasonable color low-light performance is limited by sensor size and pixel count, so results will be softer and noisier after sunset. If youâre upgrading from a basic 2â3-year-old budget phone, youâll notice a tangible improvement in color consistency and dynamic range thanks to OPPOâs processing; if youâre a photo enthusiast, this phone is meant as a dependable daily shooter rather than a creative camera tool.
Video Recording
Video recording capabilities are straightforward: the rear camera supports 1080p (Full HD) recording, usually capped at 30 fps for the default shooter on this segment device â good for shooting clips for social media, family moments and casual content creation. The advanced multi-frame stabilization and high-frame-rate slow-motion features do not provide flagship-level quality, which is a reason for the video makers to lower their expectations. Besides, the front-facing camera has a recording capability of 1080p @ 30 fps, which is very suitable for vlogging, taking selfies, and video calls. OPPOâs software usually offers stability and AI-enhancements, yet the limitations of the hardware imply that the top results will be seen only during bright, steady conditions.
Performance
Under the hood, the OPPO A3x 5G uses the MediaTek Dimensity 6300 (an efficient 6 nm-class, octa-core 5G chipset) in many market SKUs â paired with 4 GB RAM (with options for 64 GB or 128 GB storage) and OPPOâs RAM expansion features that borrow storage as virtual RAM for smoother multitasking. The Dimensity 6300 is designed for everyday snappiness: web browsing, social apps, light gaming and video streaming. It doesnât aim to be a gaming powerhouse, but casual esports titles and mid-range games will run fine on medium settings thanks to the HD screen keeping GPU load modest.

OPPOâs memory-management and ColorOS optimizations help keep the interface smooth, and the lower resolution display plus power-efficient chipset means sustained performance is steady with fewer thermal throttling concerns than a high-end phone. If heavy multitasking or top-tier gaming is your primary use case, a higher-spec device is a better pick; for balanced day-to-day performance, A3x 5G is very competitive for the price.
Software
The A3x 5G ships with Android 14 layered with ColorOS 14 (OPPOâs UI). Bringing along the well-known features of ColorOS app-cloning, smart sidebar, flexible RAM expansion, and OPPO's privacy and display options (e.g., Gentle Mode and adaptive brightness/tuning). ColorOS has still remained one of the most feature-rich Android skins, granting it an edge over its competitors with the various functional extras like screen recording, floating windows, and gesture controls throughout the day, with no trouble for those coming from other brands in terms of the friendly interface. Besides, security patches and at least a few Android OS iterations will be provided â the specific update policy is different in each market but OPPO has accelerated its update cycle recently.
Battery Life and Charging
Its comes with 5,100 mAh battery capacity. When this is coupled with the efficient processor and the HD+ screen, it leads to extremely long-lasting practical use - usually one day and sometimes even two days if the phone is used moderately (talking, texting, surfing the Internet, watching videos). OPPO has also made a claim regarding the battery's longevity, asserting that the battery will still have a good capacity after several years of usage.

On the charging front the A3x 5G supports 45W SUPERVOOC fast charging, which is generous for this price band. That means the phone recovers large chunks of battery in relatively short times compared to older budget devices with 18â33W charging. In practice you can expect around 0â~50â70% in roughly half an hour (actual times depend on the charger and cable used). OPPO often bundles a compatible charger in-box on many variants, but always verify the retailer listing to confirm the included charger.
