But this processor is also good in terms of performance. The total score of this processor is 293011. Which are a little bit higher than the Qualcomm Snapdragon 675.

Matrix 64 megapixels
Image resolution 9248 x 6936
Zoom Digital
Flash LED
Stabilization Digital
8K video recording No
4K video recording No
1080p video recording Up to 30FPS

Oppo F21 Pro has 3 cameras at the back and the main camera is a huge upgrade from the last-gen OPPO 8. The Oppo F21 Pro main Camera is 64 megapixels and had a brand new camera sensor from Samsung which is Sony IMX709 F/1.7. What makes this camera setup even more awesome is that this camera lens is combined with the wide aperture of F/1.7 and has a big size, the wider the aperture the more light will it collect and the more sharp the image quality will be. Well, one of the worst downgrades from the OPPO 7 is the ability to record at 4K. I mean why give a huge sensor with amazing performance and it cannot even record at 4K. I’m so disappointed by this. This Oppo F21 Pro can record video only at 1080P at 60 FPS. You can’t record 4K at 30FPS. The Oppo F21 Pro has 2 more camera lenses. Let’s talk about that in detail.


Wide (main) lens – 64 MP
– Aperture: f/1.7
– Focal length: 26 mm
– Pixel size: 0.8 micron
– Sensor: 1/2.74″, Sony IMX709 (Exmor-RS CMOS)
– Phase autofocus
Macro lens – 2 MP
– Aperture: f/3.3
Depth lens – 2 MP
– Aperture: f/2.4
Camera features – Bokeh mode
– Pro mode

As I mentioned above that this 64 MP sensor is good. But this Oppo F21 Pro has 2 more camera lenses. There is another camera sensor of 2MP which is a macro lens. This Oppo F21 Pro has an amazing camera design, but with no extra capabilities. There is another 2MP macro camera which is useless in the most situations because it’s only 2MP.


Megapixels 32 megapixels
Image resolution 6560 x 4928
Aperture f/2.4
Focal length 24 mm
Pixel size 0.8 microns
Sensor type CMOS
Sensor size 1/2.74″
Video resolution 1080p (Full HD) at 30 FPS

When it comes to selfie cameras the Oppo F21 Pro has a single punch whole camera of 32MP which has the largest pixels. This single-punch whole camera contains some awesome details when it comes to daytime shots. At night time this camera sensor struggles a little bit because its aperture is F/2.4 which means the photos will look accurate and will have nice skin tons and nice dynamic range, also this camera will suffer a little at night because the sensor is not that wide to capture more light. The camera video capabilities are also kept at 1080P at 30FPS only.


Wi-Fi standard Wi-Fi 5
Bluetooth version 5.1
USB type USB Type-C

This Oppo F21 Pro is launching with the Wi-Fi 5 which is faster, more efficient, and gives you less latency when compared to the Wi-Fi 4. Which will make the user experience smoother and faster. There is also the support of Bluetooth 5.1. Which is also faster and more efficient than version 5.0. Oppo F21 Pro has USB type C Gen 2.0 support. It will helps with the data transfer because it helps with the faster read and write speeds. Oppo F21 Pro also has No NFC support.


Speakers Mono
Headphone audio jack Yes
FM radio No

The Oppo F21 Pro comes with a mono speaker. This Oppo F21 Pro has average sound quality. Which is not good for a mid-range smartphone I mean Xiaomi is giving Stereo speakers with Dolby Atoms support and this phone has only one speaker. There is no 3.5mm headphone jack which is a good option for gamers.


Colors Black, Orange

The Oppo F21 Pro is going to lunch in three different colors Black, Orange. OPPO is known for its premium colors with good contexts. I like the black color because it looks better than these two colors.


This smartphone is costing around $250 which is way cheaper than the other smartphones in this category.

Final Thoughts:

If you are looking for a good Midrange phone, good gaming phone, good design, good display, and amazing performance then this Oppo F21 Pro is worth buying. Because it has all the needs that a good consumer needs.

So, this was my full review of this Oppo F21 Pro.
