So, these are the Pros and Cons of the Oppo F21 Pro 4G, now let’s see the full features and specifications of the smartphone.

Oppo F21 Pro 4G Review

Oppo F21 Pro 4G is just an overpriced phone and nothing else. Even you can get the same specifications in a Rs 15k (~205) smartphone.

Also, at Rs 23k (~310), you will not get 5G and are stuck with 4G and the processor is also not great considering the price of the phone.

Now, let’s go deeper and see what Oppo has offered in its Oppo F21 Pro 5G smartphone.


The Oppo F21 Pro 4G features a 6.43-inches FHD+ AMOLED Display with 2400 x 1080 pixels screen resolution and 90Hz Refresh Rate. It further has 180Hz Touch Sampling Rate and a 90.8% Screen-to-body ratio.


The device has Corning Gorilla Glass 5 Protection on the top while the backside is made out of leather and the frame is made out of plastic.

Oppo F21 Pro 4G Display

It also has Widevine L1 support which means you will be able to stream FHD+ content on OTT platforms like Amazon Prime Video, Netflix, etc.

As the device has an AMOLED Display, hence it has an In-Display Fingerprint Scanner to unlock the device.

The display of the phone is good, but Oppo should have included the 120Hz Refresh Rate as other brands are giving 120Hz AMOLED panels under Rs 20k (~USD 270).

Overall, considering the price point, Oppo could have provided a better display but on the other hand, the Snapdragon 680 only supports up to 90Hz refresh rate, so can’t complain much but again, OPPO should have gone with a better chip too.


The Oppo F21 Pro 4G comes with a triple rear camera setup that houses a 64MP Sony IMX709 primary sensor with f/1.7 aperture, a 2MP microscope sensor with f/3.3 aperture, and a 2MP mono sensor with f/2.4 aperture.

There is a 32MP Selfie Camera lens with an f/2.4 aperture in the punch-hole design display. Both the front and rear cameras can record up to 1080p videos at 30fps.

The device does not have OIS (Optical Image Stabilization), so it relies on EIS (Electronic Image Stabilization).

Oppo F21 Pro 4G Camera

The videos come out good but sometimes there is some shakiness in it and also the issues with dynamic range. However, the videos miss out on details in low lighting or at night. Oppo has also added a dedicated night mode but that also does not work well.

The 64MP primary sensor takes some good and the detailing also comes out well and there are no issues with dynamic range too.

Now, forget those 2MP+2MP sensors as they are added just for numbers and have no use in real-life. Here, Oppo should have included an ultrawide sensor but they didn’t which is not acceptable at this price.

The 32MP selfie camera is good but it whitens the images, so if you like saturated photos, you will be happy with the selfie camera of the device.

Overall, we can say that the camera of the device is good but they do not worth the price tag, it has an average camera setup with a higher price, nothing else.


The Oppo F21 Pro 4G is powered by an octa-core Qualcomm Snapdragon 680 Processor which is coupled with Adreno 610 GPU. It comes with 8GB of LPDDR4x RAM and 128GB of UFS 2.2 Storage.

The device runs on Android 12-based ColorOS 12 skin out of the box which is a good thing.

The device also has Virtual RAM availability. However, the extended RAM is a gimmick and it’s used only for marketing purposes and has no use in real-life, so forget about that.

We have seen many smartphones with Snapdragon 680, and the same Oppo has added in the Rs 23k (~USD 310) smartphone which is totally not acceptable.

Oppo F21 Pro 4G Performance

Considering the price of the device, we can say that the device is also compromised in the performance department. Also, the chipset does not have 5G support, so you have to live with 4G.

Oppo should have provided a better chipset like Snapdragon 778G but they didn’t, they went with Snapdragon 680 which other brands are providing at half the price of Oppo F21 Pro 4G.

Overall, the performance of the device is not good considering the price of the device.


The device comes with a 4,500 mAh Battery with 33W Fast Charging Support. Oppo has said that this charge can fully charge the device in around 61 minutes.

Oppo has included a 33W Charger inside the box of the device. However, at this price, most of the phones come with 50W or 65W fast charging support, but Oppo has only added 33W Charging. So yes, Oppo has done cost-cutting.

Also, they provided only a 4,500 mAh Battery. However, the Snapdragon 680 is a power-efficient chipset and it will give you better battery life but still at this price 4,500 mAh is low considering the competition.

Overall, we can say that Oppo has done cost-cutting in the battery and charging department.


The Oppo F21 Pro 4G does not have stereo speakers, Oppo has included a single speaker which is lout but at this price point, stereo speakers are a must thing which is missing from the device.

The device has a secondary noise cancellation microphone which helps in calling and also has a 3.5 mm Headphone Jack.

Overall, the audio quality of the device is good and is not that great considering the price.
