Oppo A3x (China)

The Oppo A3x has a non-folding, standard-form design measuring 165.7 mm tall, 76 mm wide, and 7.7 mm thick, with a total volume of approximately 96.97 cm³ and a weight of 186 g. It carries an IP54 rating, meaning it offers meaningful protection against dust ingress and water splashes from any direction, though it does not feature a fully rugged build.

The Oppo A3x uses a 6.67″ IPS LCD touchscreen with a resolution of 720 x 1604 px and a pixel density of 264 ppi, backed by a 120Hz refresh rate for smoother on-screen motion. Typical brightness is rated at 600 nits, and the panel is protected by branded damage-resistant glass. The screen does not support HDR10, HDR10+, or Dolby Vision, and there is no Always-On Display mode or secondary screen.

The Oppo A3x is driven by the MediaTek Dimensity 6300, an octa-core SoC built on a 6 nm process with two performance cores clocked at 2.4 GHz and six efficiency cores at 2 GHz, running 8 threads in total and making use of both big.LITTLE and HMP scheduling. The chip integrates an Arm Mali-G57 MC2 GPU running at 950 MHz with DirectX 12 support, alongside integrated LTE. The device ships with 8 GB of LPDDR4 RAM at 2133 MHz — expandable up to a maximum of 12 GB — and 512 GB of internal storage, with a maximum memory bandwidth of 17.07 GB/s. The CPU and memory architecture is fully 64-bit and multithreading-capable, and the cache hierarchy consists of 512 KB L1, 1 MB L2, and 2 MB L3 cache. Geekbench 6 scores stand at 782 for single-core and 2012 for multi-core workloads.

The Oppo A3x features a dual-lens rear camera system combining a 32 MP main sensor at f/1.8 with a 2 MP secondary lens at f/2.4, both using CMOS technology without a back-illuminated sensor. Autofocus is handled via phase detection and touch AF, with continuous autofocus available during video recording, though laser autofocus is absent. The main camera supports video recording at up to 1080p at 60 fps along with slow-motion capture, but there is no optical image stabilization and no optical zoom. Manual controls cover exposure, ISO, focus, and white balance, while HDR mode, burst shooting, panorama, and timelapse round out the feature set; raw shooting and manual shutter speed are not available. A single LED flash is present on the rear, though it is neither dual-tone nor RGB. The front camera offers an 8 MP single-lens shooter at f/2.0 without a dedicated flash, and the front camera is not positioned under the display.

The Oppo A3x runs Android 14 and includes a broad set of privacy controls, covering clipboard warnings, location privacy options, and camera and microphone access management, though Mail Privacy Protection and cross-site tracking blocking are not present. On the customization side, it supports dark mode, dynamic theming, theme customization, and home screen widgets, while focus modes and app offloading are not available. Productivity features include split-screen multitasking, Picture-in-Picture, full-page scrolling screenshots, a media picker, sharing intents, customizable notifications, and the ability to play games while they download. The device supports on-device machine learning, offline voice recognition, and voice commands, along with multi-user accounts, a child lock, phone tracking, and a battery health check tool. OS updates do not come directly from the vendor, Wi-Fi password sharing and Quick Start are absent, and the device cannot be used as a PC.

The Oppo A3x is equipped with a 5100 mAh rechargeable, non-removable battery that supports 45W wired fast charging, with a charger included in the box. A battery level indicator is present for at-a-glance status monitoring. Wireless charging is not supported.

The Oppo A3x retains a 3.5 mm headphone jack for wired audio and supports both aptX and aptX HD over Bluetooth for higher-quality wireless playback, though aptX Adaptive, aptX Lossless, and LDAC are not available. The device has a single speaker rather than a stereo configuration, and there is no built-in radio.

The Oppo A3x supports 5G connectivity with a maximum download speed of 3300 Mbit/s and accommodates two SIM cards alongside an external memory slot. Wireless networking covers Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), while Bluetooth 5.3 and NFC round out the short-range options. The device connects via a USB Type-C port running USB 2.0 and has no HDMI output. Location is handled through GPS with Galileo support, and onboard sensors include an accelerometer and compass, though a gyroscope, barometer, and infrared sensor are all absent. A fingerprint scanner is present for biometric authentication, while 3D facial recognition and an iris scanner are not available. The device does not include a stylus, built-in projector, heart rate monitor, ANT+ support, DLNA certification, crash detection, or emergency SOS via satellite.

The Oppo A3x includes a video light for illuminating subjects during video recording. The display is flat rather than curved and uses neither sapphire glass nor e-paper technology.
