Case and features - Angular and splash-proof
With its angular casing, the Oppo A77 5G looks modern and chic. The color options are a light blue and black, both with a matte shimmering back and a metal-look frame. The casing is made of plastic overall, but it is solidly manufactured and does not creak when twisted.
Oppo even had its smartphone certified to IPX4. However, you should not take your phone diving with you, because it is only protected against splash water.
There are two storage variants of the Oppo A77 5G:
- 64 GB mass storage / 4 GB RAM: 279 Euros (~$275) manufacturer's price
- 128 GB mass storage / 6 GB RAM: 329 Euros (~$324) manufacturer's price
You can insert two SIM cards into the phone at the same time, but you have to decide whether you want to use a second SIM or a microSD for memory expansion, since they share a slot. The card reader does not transfer data very quickly, but it is still within the range of the comparison devices.

Communication, software and operation - Stable WLAN on the Oppo phone
The Oppo A77 5G is, as the name suggests, a 5G phone that only supports sub-6 GHz frequencies. The frequency selection is decent, but if taking a trip, you still have to see whether you can use the 4G or 5G network in the destination country.
WiFi 5 is the fastest WLAN standard that Oppo's smartphone supports. Thus, it achieves stable speeds around 350 MBit/s, which is common for this class.
Oppo installs its own UI ColorOS, which is based on Android 12. The security patches are from September 2022 and thus still fairly up-to-date at the time of testing. A few advertising apps are preinstalled.
The slightly recessed and elongated standby button already reveals that the fingerprint sensor is also hidden here. It works quite reliably, but it could be felt more clearly. Unlocking via face recognition also works well. However, the quick setup suggests that not much image data is collected here and that the function can be tricked quite easily.

Cameras - Actually only one optics
Although the Oppo A77 5G shows two large camera circles on the back, it actually only hides one camera that you can really use: Besides the main camera with 48 megapixels, there is namely only a support lens that does not take its own photos.
The main camera usually combines 4 pixels each to get more light-sensitive pixels, so it usually takes 12-megapixel photos. The pictures look quite well exposed and also sufficiently detailed for a mid-range camera.
In low light and high contrasts, the brightening in dark areas succeeds on average with quite strong image noise. The lab shows that the subject can still be guessed at an illumination of 1 lux, but details are no longer visible.
Videos can be recorded in 1080p with 30 fps at most, which is also common in the price range. Brightness adjustment and autofocus work quite well, but the latter does not manage without pumping. The picture quality is decent.
An 8-megapixel camera is found on the front. It takes decent selfies, but you should not look at the pictures in too much detail, otherwise you will notice the rather coarse structures and little detail in dark areas.

Display - More pixels would have been nice
Oppo installs a bright screen with a decent contrast ratio in its phone, but unfortunately there is a catch: The resolution is only 720p, which is much lower than the Full HD screens of most similarly priced smartphones. This leads to a blurrier display and is also visible in a direct comparison.
In our measurements, the screen shows a slight bluish cast, but it manages without PWM, so everyone can use the Oppo A77 5G without headaches.

Performance, emissions and battery life - Typical performance, good runtime
The MediaTek Dimensity 810 is a mid-range SoC and thus fits well with the Oppo A77 5G. The processor does not quite reach the performance of similarly priced smartphones, but the phone can keep up in the graphics area. The results are even quite good in the on-screen benchmarks, which is due to the 720p resolution placing fewer demands on the graphics unit.
It quickly becomes apparent that there are hardly any performance reserves in everyday use: The computing power is sufficient for simple tasks, but the Oppo A77 5G is pushed to its limits when you even want to adjust the volume during demanding apps. The installed UFS 2.2 memory transfers data quite quickly.
The maximum temperature of 43 °C (109.4 °F) under longer load is quite noticeable, but not yet unpleasant. Moreover, the SoC does not throttle even under permanent load.
The mono speaker on the bottom edge sounds a bit thin and quite treble-heavy, which is amplified when you increase the volume beyond the maximum and activate the "Ultra Volume Mode". The volume is then quite OK, but music sounds unpleasantly glaring in the ears. External audio devices can be connected via a 3.5 mm jack and Bluetooth. Numerous aptX codecs are also available for the wireless connection.
With its 5,000 mAh battery, the Oppo A77 5G is on par with comparable smartphones. It also gets good runtimes out of the battery with 17:12 hours. The maximum charging power via the included charger is 33 watts. It takes just under 2 hours until the battery is back to 100% when the battery is completely empty.

Pros
Cons
Verdict - Fit for not too high demands
The Oppo A77 5G does its job: It can keep up with similarly priced smartphones in most areas and hardly has any real weaknesses apart from the low-resolution screen and the meager speaker. At the same time, you should not expect too much passion: The Oppo A77 5G is a solid worker without big ambitions to be something special.
Only the software and the angular design show a bit of originality. Oppo has even afforded an IP certification, but that is probably more for marketing purposes since it is only about protection against splash water.
If you are looking for a stylish phone with stable Wi-Fi, modern Bluetooth and good runtimes, you can give the Oppo A77 5G a chance. However, you should also keep the slightly higher prices in mind compared to the storage configuration and look for good offers
The Oppo A77 5G is a solid mid-range phone in many areas, but you have to cope with the higher price and the low-resolution screen.
If you are looking for alternatives, you will get the cheaper Xiaomi Poco M4 Pro 5G, a phone with an even longer battery life and even stereo speakers. If you like ColorOS, you can also look at the OnePlus Nord CE 2 Lite 5G which offers a bit more performance and a higher-resolution display.
Price and availability
The Oppo A77 5G is available on the Internet from many retailers in both memory versions.
You should compare the prices: The version with 64 GB mass storage costs at our lender cyberport.de at the time of testing, but is already available at amazon.de for a favorable 239 Euros (~$236).
The 128 GB variant is available at cyberport.de for 322 Euro (~$318), at amazon.de it costs 276 Euro (~$272).
