Case - Reno4 Pro with a proprietary colour scheme
The Reno4 Pro has a metal frame and a glass back with a matte surface. The build quality is on a good level. The smartphone comes in the following colour schemes: "Galactic Blue", "Space Black" and "Green Glitter". According to the manufacturer, the "Green Glitter" colour scheme was developed in collaboration with Pantone. The screen is protected with Corning Gorilla Glass 5. Our review device is quite light (172 grams/~6 oz) and has very small bezels, which is why it looks very modern.
Connectivity - Oppo smartphone without an audio jack
Our review device features neither a headphone jack nor a microSD card slot. The Oppo Reno4 Pro supports dual SIM functionality. However, only one of the two nanoSIM cards can operate in 5G networks. The Android smartphone supports both VoLTE and VoWiFi. Wired data transfers can be carried out via the USB Type-C port, which operates at USB 2.0 speeds. The Oppo smartphone also supports Widevine L1 DRM and the Level 3 Camera2 API.
Software - Android 10 with ColorOS
The Reno4 Pro runs Android 10 with Oppo’s proprietary launcher known as ColorOS (version 7.2). The security patches were last updated in September, 2020. Oppo’s launcher offers different icons and a custom settings menu when compared to stock Android. Preinstalled applications such as video editor Soloop and WPS Office can be uninstalled without any problems.
Communication & Geolocation - 5G smartphone with Wi-Fi 5
The Oppo Reno4 Pro supports the following mobile communication standards: GSM, 3G, LTE and 5G. For short-distance communication, our review device relies on NFC, Bluetooth 5.1 and Wi-Fi 5. With our reference-grade router Netgear Nighthawk AX12, Oppo’s smartphone achieves mediocre data reception and transmission rates. When it comes to the download speeds in particular, the Reno4 Pro is beaten by the rest of the competition.

Outdoors, the Oppo smartphone has a margin of error of up to 4 metres (~13 feet). We use an application known as GPS Test to help us determine the margin of error. In order to determine how accurate our review device is when it comes to geolocation, we take it with us on a bike ride. During this ride, we are also accompanied by the professional navigator Garmin Edge 500. The 5G smartphone was slightly less accurate than the professional navigator.
Telephony & Call Quality - Call partner is easy to understand
The phone application offers direct access to the favourite contacts. Users can bring up the dial pad by tapping a button. There are also two other tabs; one for call history, the other for saved contacts. The Oppo smartphone provides a high call volume. The voices on either end of the call sound clear and intelligible.
Cameras - Good optical zoom
The Reno4 Pro comes with a triple-camera system, which produces well-detailed and colour-accurate images. Photographs taken with the ultra wide-angle camera appear punchy. However, they are somewhat blurry, especially at the edges. Homogeneous surfaces are also poorly reproduced. The telephoto lens produces slightly blurry, but colour-accurate, photographs. Under low-light conditions, the camera system takes very poor photos. The camera application offers a “Pro” mode, which allows users to adjust the white balance, ISO sensitivity, brightness and the shutter speed.
The front-facing camera takes good photographs, which are not as sharp as the pictures taken with the main shooter. The portrait mode allows users to blur the background. The selfie shooter does not offer a “Pro” mode. Videos taken with the Oppo smartphone look as good as the photographs. Video can be recorded at 1080p and 720p at 60 or 30 FPS. The smartphone can only shoot 4K video at 30 FPS.

Accessories & Warranty - USB Type-C headset and protective case in the box
The box of the Oppo Reno4 Pro contains a USB charger with an appropriate USB Type-C cable, a silicone protective case, a SIM card removal tool and a USB Type-C headset. The manufacturer offers additional accessories such as wireless headphones on its website.
The Reno4 Pro comes with a 24-month warranty.
Input Devices & Handling - Sluggish in-display fingerprint scanner
The Reno4 Pro comes with Android’s standard keyboard, which is known as GBoard. The touchscreen reacts reliably and promptly to inputs. The drag-and-drop functionality works well. In landscape mode, the keyboard can be moved around the screen.
The in-screen fingerprint sensor proved to be unreliable in our review. The face unlock worked much better. However, it does not get you straight to the home screen. In order to get to the home screen, users will have to swipe up on the lock screen.
Display - Responsive 90-Hz panel
The 6.5-inch AMOLED display of the Oppo Reno4 Pro has a native resolution of 2400x1080 pixels. Thanks to an average brightness of 789 cd/m², the Oppo smartphone takes first place in our comparison chart. In the APL50 test, in which the screen displays a pattern of alternating black and white squares of equal size, we measured an even higher brightness of 1034 cd/m². With the light sensor disabled, the screen brightness drops to 485 cd/m². The minimum brightness level amounts to 3.07 cd/m².
According to our measurements, the OLED screen of the smartphone flickers at frequencies ranging from 183.8 Hz to 367.6 Hz.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 367.6 Hz | ≤ 99 % brightness setting |  |
The display backlight flickers at 367.6 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 99 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 367.6 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8516 (minimum: 5 - maximum: 343500) Hz was measured. | |||
Both the contrast ratio and the black value of the AMOLED panel are superb. Users can adjust the colour reproduction in the settings menu.
There are two preconfigured colour profiles: "Vivid" and "Normal". In Vivid mode, there is an observable bluish cast and the colours appear oversaturated. In Normal mode, the colours appear more natural and the colour temperature is closer to the desirable target.

Thanks to a high brightness, the screen of the Reno4 Pro is legible outside. However, occasionally, reflections make the screen difficult to read.
There is a green cast when the AMOLED screen of the Reno4 Pro is viewed at extreme angles. However, at normal angles, there are no issues.
Performance - Good level of performance, but not ahead of the competition
The Oppo Reno4 Pro comes with the Qualcomm Snapdragon 765G. It performs as well as other devices with the above-mentioned SoC. In our benchmarks, the Oppo smartphone is only able to compete with the ZTE Axon 11 5G. Nevertheless, in everyday use, the smartphone feels very responsive and applications work without any issues.

Pros
Cons
Verdict - Oppo Reno4 Pro slots in the 5G segment
The Oppo Reno4 Pro is a modern and slim smartphone. The camera performance is good and the system performance leaves nothing to be desired as well. The great battery life is a big positive. Moreover, the battery can be fully charged in half an hour. The Oppo smartphone scores some major points when it comes to LTE and 5G performance, but it does not do particularly well when it comes to Wi-Fi performance. 256 GB of internal storage is more than enough at the moment. However, the storage capacity is not expandable, because the Reno4 Pro does not have a microSD card slot.
The Oppo Reno4 Pro is a 5G smartphone with aggressive energy-saving features, which bring something to the table.
However, users should pay attention to the aggressive energy management. The smartphone routinely closes applications that are running in the background, which may not be welcome in certain situations. For instance, we had trouble getting an application, which prevents the screen from switching off, to run in the background. The same applies to fitness trackers and navigation applications. Howbeit, users can disable energy-saving functions for any application they choose.
