Review OPPO A77 | Simple cell phone with top of the line price

Câmera traseira - OPPO A77

Oppo arrived in Brazil officially last year and until then brought us two models of cell phones. The last of them, the OPPO A77, was introduced in our country in September 2022 and arrives to compete for space in the most basic cell phone market.

The cell phone has simpler specifications and its proposal is to reach a less demanding public, who want a simple device to use on a day-to-day basis, but which does not fall short in basic aspects, such as browsing social networks.

But does it live up to that expectation? Is it worth opting for this cell phone or is it better to stick with manufacturers that are already popular in our country, such as Samsung and Motorola? I tested the OPPO A77 and now I bring my opinion about this entry-level cell phone from the Chinese giant.

  • Below average battery

Design and Construction

Design is something the Chinese company gets right on the OPPO A77. Despite the simpler construction, with a plastic back, it looks very elegant, with straight sides and a matte finish on the back. The module that houses the pair of lenses is discreet and very sophisticated.

The sides are made of metal and this further improves the appearance of the device. With all this structure, it is still a very light smartphone, with only 187 grams.

The screen has a drop-shaped cutout, which houses the front camera. I found the choice of this format a little late, especially if we consider that many models already adopt something more discreet, such as a hole. However, this design is more common for input devices.

Being a simpler model, don’t expect water or impact resistance certifications — it doesn’t have any IP grade and the screen doesn’t have Gorilla Glass or similar protection.


The OPPO A77 has a 6.56-inch IPS LCD screen with a refresh rate of 90 Hz and a resolution of 720 x 1612 pixels. Overall, it’s a very simple screen that lets you see content from social networks well, but it may not offer the best quality for watching movies and series, for example.

Its refresh rate is more average. It’s not bad, to the point of compromising both the frame rate when playing games, but it’s also not the most suitable for this purpose — not least because it is a more basic cell phone model.

The display type is IPS LCD — common material in this segment. With it, you will have simpler views and the brightness level is sometimes not enough to see everything more clearly, especially if it is very sunny.

configuration and performance

The OPPO A77 offers a very basic performance, even for what it is proposed. The cell phone has a MediaTek Helio G35 chip, which offers a maximum frequency of 2.3 GHz in four of its eight cores.

In practice, that wouldn’t be so bad, but this chipset, coupled with just 4GB of RAM, can’t offer such smooth performance even when scrolling through social media feeds. On Twitter, for example, it is possible to notice some stuttering as you progress through the timeline and this is also repeated on Instagram or Facebook.

I even ventured out to play a bit with it and ran Call of Duty: Mobile. The game, being well optimized to run even with simpler platforms, until it runs smoothly, with few stutters, but the graphic quality is quite compromised.

Other than that, the handset has a unique option of internal storage which is 128 GB. This space is more than enough to save a lot of files, but if you tend to download a lot of apps and take a lot of photos, you may need to use a memory card — which is compatible with your cell phone.

As for our standard benchmark, it couldn’t handle running 3D Mark’s Wild Life, so I just ran Sling Shot Unlimited and Sling Shot Extreme Unlimited, with scores of 535 and 897, respectively. As a comparison, this average is even lower than the Moto G7 Power, a cell phone launched in 2019.

In Benchmark 5, it scored 175 points in the single-core Reviews and 996 in the all-core test. The GPU performance was 88 points.


The Oppo A77 currently has the ColorOS 12.1 interface, which is developed by the brand itself based on Android 12. With that, it has some of the company’s own features and look, with a lot of modifications in relation to “pure” Android.

In addition, the phone already comes with some pre-installed applications — such as Facebook, Netflix, TikTok and Kwai. This can be a nuisance for those who don’t use these apps and have to uninstall them, as they already occupy a good amount of space in the internal memory.

Other than that, there are some interesting items to mention, such as the fingerprint unlock sensor on the side, which offers a lot of agility in authentication.

It is also important to note that this is a cell phone that only supports the 4G network, so if you are looking for something more up-to-date and that you will not need to change over the next few months, it might be better to rethink the purchase of this model.


The Oppo A77 has a dual set of rear cameras, with a 50 MP main sensor assisted by a 2 MP depth sensor, and an 8 MP front lens. In practice, however, the result is not so satisfactory and the images obtained by the device are not so clear.

On the front camera, only one lens works to get the photograph. The other only serves to apply the blur in portrait mode, so you won’t have as much versatility to take macro photos or with a larger field of view, for example.

In common mode, made with the main camera, the images are poorly defined and this can be noticed more clearly in scenarios with a lot of details, such as plants or trees in the background. At least the cell phone can manage colors well so as not to blow out the white, even in well-lit places.

Already indoors, even with a good amount of lighting, it is possible to notice a lot of pixelation in the photo. This happens with both the front and rear camera, but it’s much more noticeable in selfies.

Video recording

The Oppo A77 shoots at a maximum resolution of 1080p on both the front and rear cameras, with a frame rate of 30 fps in both cases, with no option to change it.

In both cases, the result is satisfactory. The level of stabilization is quite low, but nothing that deviates from the standard for cell phones in this category. As for the definition, the 1080p delivers a good result, but nothing surprising. See, below, some examples of videos taken with the rear and front camera of the A77.

Sound system

The Oppo A77 has a stereo audio set, with a main sound output at the bottom and the other one sharing space with the phone’s speaker. In general, it offers a very high volume level, thanks to the “ultra volume mode” available in the interface. Sound quality, however, is a bit compromised in this configuration.

At a more intermediate level, however, it is possible to have a more acceptable performance, but nothing that deviates from the standard for mobile phones, of course. One positive point is that it has a dedicated headphone jack with a 3.5 mm plug, so you won’t have a problem if you want to use a wired accessory or a speaker.

battery and charging

The Oppo A77 has a 5,000 mAh battery which, on paper, is about average for most cell phones today. Performance, however, is not as good as expected.

In our standard test, it consumed 18% of its charge after 3 hours of Netflix playback with brightness set to half. This yields a duration estimate of 16 total hours. This is almost the average, but there are cell phones that are around 15% consumption with the same battery capacity.

In everyday life, autonomy is similar and, with moderate use, it can even reach a day of duration, but if you use social networks and mobile data more frequently, it may be necessary to charge the device again before use. end of the day.

As for charging, a clearly negative point. In times of cell phones that are fully charged in up to an hour and a half, the Oppo A77 takes two hours to have a full charge. That’s average for entry-level phones, but it’s still a bad mark.

direct competitors

Comparisons of the Oppo A77 can be made with two models from very popular brands in the Brazilian market: the Galaxy A04e and the Moto G42. The three have a very similar set of hardware and performance at almost the same average.

For starters, the Samsung model is equipped with the same chip as the A77 — the MediaTek Helio G35. However, it has only 3 GB of RAM, 1 GB less than the rival, and has a simpler set of cameras, with a dual 13 MP + 2 MP on the rear and 5 MP selfies.

However, it is worth noting that the Galaxy is a much more accessible model and has a better optimized interface. Its price range is currently around R$ 900.

The Moto G42 is a little more expensive, around R$ 1,300, but it is a more complete model. It has the Snapdragon 680 chip with combination of 4GB of RAM and 128GB of storage. Its set of cameras is also more attractive, with a main 50 MP, aided by an 8 MP and a 2 MP, with a 16 MP front lens.

As for the price, the Oppo A77 is much less attractive and costs from R$ 2,200 to R$ 2,500 in the Brazilian market. In this range, it is already possible to find top-of-the-line models, such as the Galaxy S21 FE — which has already cost R$ 2000 in the last 40 days — or the Motorola Edge 30, which is currently found in the range of 2,400.

OPPO A77: an entry-level model that does not convince for its high price

The Oppo A77 is a very basic entry-level model and doesn’t shy away from it. It has a very simple chip and modest combination of RAM and storage. This makes its performance very low and it is possible to notice this already in everyday tasks, which no longer require much of the processor.

Its set of cameras is also not attractive and serves more for sporadic records, being well below average. If you want a cell phone that serves this purpose at least well, better consider other options. The look is the only attraction in this device, which has a very…
