Design and display

In terms of design, the Oppo A78 5G It is available in 3 color presentations: black, blue and purple.. In any color it looks great, it has flat edges, which makes it very practical and comfortable to wear, in addition, it is 7.99 mm thick and weighs about 188 grams.

When detailing it, we will notice that on its back it has the company logo at the bottom and two cameras in the upper left corner. There is no photo module as such, so each sensor protrudes from the rear cover.

As far as the front is concerned, the phone has nothing new to offer. We can see a waterdrop notch for the location of the front camera. The screen has a 2.5D glass on top along with thin surrounding bezels but a very thick chin.

The bottom edge has a 3.5mm headphone jack, microphone, USB-C port, and speaker grill. The left side of the phone has a hybrid SIM slot. The volume up and volume down buttons are also located on the left. Meanwhile, the right edge has a power button, which is integrated with a fingerprint sensor.

Moving on to the topic of the screen, andl Oppo A78 has a 6.56-inch IPS LCD panel that offers an HD + resolution of 720 x 1612 pixels and a refresh rate of up to 90Hz. Although it has a good level of brightness, color representation and viewing angles, it is difficult to ignore the obvious: HD + resolution in the middle of 2023 and from a mid-range … something inconceivable.

As a consolation, the stereo speakers have good sound, so at least we can enjoy music and video with good audio quality.

Hardware and features

The OPPO A78 is driven by a veteran MediaTek Dimensity 700, a 7nm chip and 5G connectivity that has become the most popular choice in the mid-range, so we already know what to expect. It is accompanied by 8GB of RAM that can be expanded up to 16GB virtuallythat is, using part of the internal storage, which by the way is 128GB (UFS 2.1).


With that in mind, the Oppo A78 achieves a score of 555 points in the Geekbench 5 single-core test and 1,700 points in the multi-threaded testwhich is normal for a device with this hardware, so we can expect a smooth experience in day-to-day tasks and applications, and with those 16GB of RAM we doubt that it will slow down when having multiple apps open.

It’s not stellar performance, that’s for sure, the most demanding Android games will easily make us see its limitations, but it’s normal for a mid-range smartphone that costs around 300 euros.

Feeding the terminal we will get a battery of 5,000mAh with 33W fast charge. It gives us up to 14 autonomy with local video playback, so it easily lasts us for a day (or more) of normal use. The fast charge is not the best on the market, but if it is any consolation, in a matter of 70 minutes it can recover 100% of its capacity starting from 0%.

Changing the subject, the operating system of the day is Android 13but unfortunately it does not come alone, Oppo’s interface (ColorOS 13) is present and brings with it a sophisticated look, but also a lot of bloatware for our taste.

The Oppo A78’s main camera is less impressive than its megapixel count suggests (50MP+2MP), but still holds up reasonably well in this price range. If you want details of its photographic performance, we will not deny it, and here we can say that the image processing could be better, because although the photos retain an excellent level of detailthey look oversaturated and oversharpened.

Perhaps the worst thing about the camera is its limited dynamic range, with shadows and reflections appearing significantly less prominent than the actual scene. The A78 5G also has a 108MP ultra-clear image function that increases the resolution from 50MP to 108MP. This helps with contrast, but it doesn’t necessarily increase detail, but you know what it does? The weight of the photos in 50%.

OPPO A78 - Cameras

Despite how negative what has been said so far may sound, this photographic performance is really to be expected in the mid-range, so we cannot lower many points.

For his part, heThe front camera is 8MP and can take high-quality selfies in different lighting conditions.. The only problem with it is that it has a little delay in the capture response, but we are talking about fractions of a second, so it is tolerable.

Those interested in the OPPO A78 can purchase it through the classic amazon storebut it can also be found available in Carrefour for a competitive price. Also, the English Court has it for sale and buy it from Media Markt is another viable option. Naturally, it is best to check all the offers before making a decision.
