On looks, the Oppo A31 won't win you over in a jiffy. It does not offer an original design. Its most sympathetic looks are in white-green and green. This is largely due to the matte finish on the rear panel. As for the Oppo A31 in black, it will please gloss fans. That's right, the casing has a nice gloss finish that makes the phone more solid in appearance and presentable. The only downside to this solution is that when you grasp the device in your hands, your fingerprints immediately remain on it. Thanks to the included silicone case, this problem is partially solved.

In terms of ergonomics, this model is comfortable for one-handed operation. Its dimensions are respectively 163.9 x 75.5 x 8.3 at a weight of 180 grams. All buttons are located in intuitive places. Only the lack of a clearly marked area on the fingerprint scanner may make it a bit difficult for you at the very beginning.


The Oppo A31 will win you over with its 6.5-inch screen with a resolution of 1600 x 720 pixels. The top of the display has a teardrop notch for the front camera. The display brightness is typical - 480 nits. You won't notice any discomfort during operation. In 2020, it is mainstream to launch smartphones with quality matrices with good color rendering and brightness. The Oppo A31 is no exception.

To the work of the fingerprint scanner there is no criticism. Unlocking is fast and precise, there is no unnecessary delay. An alternative to this scanner is facial recognition. It will also please you, even in conditions where the light is insufficient.


Under the hood of the cute Oppo A31 is an 8-core MediaTek Helio P35 SoC, consisting of 4 Cortex-A53 cores clocked at 2.3 GHz and 4 Cortex-A53 cores clocked at 1.8 GHz. The internal memory is 64 GB (expandable using microSDXC) and the RAM is 4 GB (LPDDR4x). In everyday tasks, such as using the messenger, taking pictures with the camera, browsing the web or scrolling through social networks, you will notice stable performance. With games, the Cortex-A53 handles just fine. For more resource-intensive games, you need to be clever - lower the settings to minimum or medium.

Of the wireless modules, Wi-Fi 5 (2.4 GHz / 5 GHz), Bluetooth 5.0, GPS are available. Oppo has declined to offer NFC for contactless payments. This is one of the downsides of the Oppo A31.

The smartphone runs on Android 9 operating system with ColorOS 6.1.2 interface.


Will you take quality photos and videos with the Oppo A31? Possibly. The device features a triple main camera. The main module is a 12-megapixel with an f/1.8 aperture. Provided are two 2-megapixel modules, one of which is a sensor for measuring the depth of the frame, and the second is responsible for macro photos.

During daylight hours in good light, the camera works almost perfectly. The detail is poor. The Oppo A31 will delight you with excellent close-up shots. You also get a special mode for night shots. The darker it gets outside or indoors, the faster the quality of the photos drops.

With the Oppo A31 in hand, you can capture interesting videos at 1080 pixels resolution at 30 frames per second.

Autonomous operation

In 2020, it has become clear that smartphones with battery capacities below 4000 mAh will be rare. The Oppo A31 offered a bit more - 4230 mAh. Given the screen's HD specs, and the undemanding platform, you can expect the battery to last a full day of active use. If you're more frugal, even up to two days.


Whether you opt for the green, black, or white-green Oppo A31, you can congratulate yourself on an excellent budget-grade model. While it doesn't have a top chipset, the system runs fast and flawlessly. With this smartphone, you can recharge the battery after two days, watch your favorite videos and portals on the quality screen and enjoy good quality photos.
