What is it?

OPPO A31 is a budget smartphone with 6.5-inch HD + IPS-display with a drop-drop, budget MediaTek Helio P35 processor, 4 GB of RAM and 64 GB of internal memory expandable with MicroSD cards, a rear triple camera with a main module of 12 MP and two auxiliary 2 MP (macro and depth sensor). The smartphone is powered by a 4230 mAh battery, runs on Android 9 Pie OS with Color OS 6 shell. Everything is contradictory with the interfaces: there is dual-band Wi-Fi and Bluetooth 5.0, but there is no NFC, and MicroUSB is used to connect the cable.

What is included?

OPPO A31 packed in standard box sizesin white-green colors with the image of a smartphone. Inside - almost a standard set: smartphone, charger, MicroUSB cable, tool for removing the tray, documentation and a couple of small, but nice bonuses in the form of a protective silicone bumper and a protective film (immediately on the screen).

What does the OPPO A31 look like?


</ img>

In general, it’s difficult to somehow scold or praiseOPPO A31 design: in front, it looks similar to most modern smartphones in the middle and budget price ranges. Before us is a large screen with rounded corners, a drop-shaped notch for the front camera and a thin slot in the earpiece above the screen. Everything is absolutely familiar: the frames are not the most record (especially the chin), but it looks decent.


</ img>

The rest of the body is made of plastic and hasnice streamlined shape. Apparently, not the most familiar arrangement of buttons - the chip OPPO and A31 in this regard was no exception. The buttons are spaced on different ends of the smartphone, the power button is on the right.


</ img>

The volume control buttons are separate andare on the left side. Despite the not the most standard solution, the buttons (both power and volume) are placed at a good height and it is convenient to use a smartphone. The tray is also on the left.


</ img>

And in the OPPO A31 it can simultaneously accommodate two SIM-cards and a memory card, so that you can not deny yourself anything.


</ img>

Bottom - speaker, microphone, standard 3.5 mm headphone jack and MicroUSB jack. Yes, MicroUSB is still installed on a bunch of state employees. On the other hand, there is probably a cable both at home, in the office, and with friends.


</ img>

On the top face nothing interesting was found.


</ img>

The back is completely plastic. We have black, green and such white options. Although it is not completely white, it leaves a little green. Interestingly, the black version is glossy, our white (and, it seems, green) is with a matte rough finish. It lies well in the hand, does not slip out and fingerprints do not remain on it. This option seems more practical to me. According to the layout - in the lower right corner - the OPPO logo, in the opposite - the vertical module of the main camera, in the middle - a fingerprint scanner. He is surrounded by a thin golden edging and at first he does not feel too well. Although in the bumper there will not be such a problem at all.


</ img>

The rear camera The camera protrudes just a little above the body, but in general it is done carefully. Apparently, the main module is located in the middle, and two on 2 MP - on the sides.

How good is the screen?


</ img>

The smartphone has a large screen with a diagonal6.5 inches Of course, with elongated proportions, in this case - 20: 9. Resolution is not its greatest strength: 1600x720, pixel density - about 270 ppi, which is quite modest by today's standards. But a good IPS-matrix is ​​used and there is no grainy grain. There is a standard set in the settings: brightness, scale of interface elements, font size and night mode with warm colors. There is no dark theme. As well as individual color rendering modes. But there is a manual adjustment of color temperature.

Hardware measurements showed that the screen is verynot bad in its characteristics: the maximum brightness is 396.694 cd / m², the brightness of the black field is 0.383 cd / m², and the static contrast ratio is 1036: 1. Color rendering is also very good, deviations from the reference indicators are very small, the average color error ΔE is 4.26, and the color gamut is close to the sRGB color space:

What are the unlock methods?


</ img>

To unlock the smartphone, you can usetraditional rear fingerprint scanner and face recognition. Everything is clear with the scanner, and it works without problems. For face recognition, of course, only the front camera is used, so this method is not too safe. But it works not bad: in good lighting it quickly, in poor lighting it also copes, but it takes a little more time. The backlight from the screen of the smartphone is enough for this purpose.

What about performance, memory, sound and autonomy?

The OPPO A31 has a fairly budgetto today's standards, the filling: the Mediatek MT6765V / CB processor, aka Helio P35, 4 GB of RAM LPDDR4X and 64 GB of internal memory eMMC 5.1. Helio P35 is a 12-nanometer processor, which includes a block of 4 ARM Cortex-A53 cores at 2.3 GHz and another 4x Cortex-A53 at 1.8 GHz, PowerVR GE8320 accelerator is responsible for the graphics. Of course, with performance tests, the smartphone shows modest results. In terms of stability during long-term loads, everything is not bad: performance in some moments sinks up to 89%, after which it returns closer to maximum.

In real life, the interface and applications workok, don't slow down. Although the difference is felt if previously used flagships: everything does not work so smartly. You can play modern games. At minimum settings, of course, including Call of Duty Mobile. Including due to good optimization. Asphalt 9 is also playable, but friezes periodically happen.

In a proprietary utility, you can turn off notifications for the duration of the game, adjust performance, and more.

There are dual-band wireless interfacesWi-Fi 802.11 a / b / g / n / ac 2.4 GHz and 5 GHz, Bluetooth 5.0 LE, global GPS positioning systems are supported, support for A-GPS, Beidou, Glonass. NFC, unfortunately, is missing. On wired ports, the OPPO A31 has a MicroUSB and a standard audio jack. There is only one speaker; it is mediocre in volume and quality. The sound in the headphones is quite OK for the average user. There is an FM tuner that may come in handy for someone. Of the unusual chips, there is the “party” application, which allows you to play one song at once from several smartphones (for example, in case there is no portable speaker in nature).

</ img>

The smartphone is powered by a 4230 mAh battery,quite good with a low resolution display and modest performance. Fast charge is not supported. In fact, given the potential audience of the smartphone, and these are clearly not gamers, the smartphone lasts two days on a single charge. Although, in fact, casual games will also not greatly drain the battery. So, in general, if you use calls, instant messengers, mail, a browser and sometimes YouTube, then the smartphone is quite able to please autonomy. Of course, there are power-saving modes for critical cases.

What about the interface?


</ img>


</ img>

OPPO A31 runs on Android 9 with proprietaryColorOS shell 6.1.2. Given that the smartphone is new, you can certainly expect an upgrade to Android 10 complete with Color OS 7. There are no complaints about the current version: there are no bugs, brakes or critical problems with localization. It works stably. Outwardly, the interface was completely redrawn, but there are no cardinal differences in the work itself. As with most third-party shells, manufacturers change the appearance and add a little functionality. Standard desktops are available where you can place application shortcuts and widgets, and you can also enable a separate menu with applications. The curtain was modified a little: it is still two-level, but it opens in full screen.

There are enough navigation options: standard 3 buttons, two-button option and fully gesture control. There are also additional gestures for quickly launching various applications, taking screenshots and so on. Application Manager is standard, split-screen mode is present.

Of the interesting chips there is the so-called“Smart Panel”. By its logic, it reminds Edge Panels from Samsung or Side Sense from Sony. A panel with quick access to the necessary functions, which is called from the edge of the screen in the right place:

In stock applications there is everything you need, including a file manager, voice recorder, a utility for migrating between phones and even a simple video editor.

How good are the cameras?


</ img>

The configuration of the cameras is pretty simple:the rear camera consists of a 12 megapixel main module with f / 1.8 aperture and phase detection autofocus. There is an additional macro camera with a resolution of 2 MP, f / 2.4 and a depth sensor of 2 MP, f / 2.4. Video writes in [email protected] Front camera - 8 MP, f / 2.0.The proprietary camera application is extremely easy to use. The main modes are switched by swiping: photo, video and portrait. Additional modes - in the drop-down menu. Unfortunately, there is no night mode. The main screen has settings for flash, HDR, filters, and digital zoom toggle.

It’s worth remembering that before us is a budgetsmartphone, camera wonders can not do. In the afternoon, the main camera takes nice photos with good detail and pretty natural color reproduction. In the evening, it can be seen that the matrix begins to make noise at higher ISO values ​​and mainly “soap” is obtained.

In general, additional cameras in such smartphones are more a tribute to modern trends and marketing. But the camera as a whole copes with blurring the background.


</ img>


</ img>

Macro photography - it may be useful in some rare cases, under certain good conditions. In good light and a still subject. Focus is not so simple.

Video in FullHD takes off, without any frills: no stabilization.
