Vivo V20 has a way better built quality and in-hand feel when compared to the plastic built Galaxy M51 which takes scratches very easily.

Display: The most Important

Display of a phone matters the most while buying a smartphone because you are going to use it everytime.

Samsung Galaxy M51

The Galaxy M51 has a 6.7 inch Full-HD+ Super AMOLED+ Infinity-O-display with a punch-hole design and a 60Hz refresh panel. The screen resolution is 1080 x 2400 pixels with a screen to body ratio of 86.66% and an aspect ratio of 20:9 and 385 ppi density. There is Corning Gorilla Glass 3 protection on the front. It has a peak brightness of 420 nits

Vivo V20

It has a 6.44 inches AMOLED display with FHD+(1080×2400 pixel resolution), 409 ppi (pixels per inch) and 20:9 aspect ratio. The dimensions are 161.3 x 74.2 x 7.4 mm (6.35 x 2.92 x 0.29 in) and weighs 171g. The smartphone has a glass build with gorilla glass protection. It has a peak brightness of 600 nits.

Points of difference: Who is the Winner

The Galaxy M51 has a better display with sAMOLED+ panel whereas Vivo V20 has an AMOLED panel. sAMOLED is the upgraded version of AMOLED and sAMOLED+ is the upgraded version of sAMOLED. The display on the Galaxy M51 is very thin when compared to an AMOLED display panel on the Vivo V20 and consumes relatively less amount of battery and is more brighter. In comparison, the colors on the Vivo V20 look a bit dull. When both the displays are compared side by side the Galaxy M51’s display looks way better and shows more brighter colors.

The Vivo V20 has a better peak brightness than the Galaxy M51 and beats the Galaxy M51 in brightness when indoors by slight amounts. This means that you can make the dull colors on the display look brighter by increasing the brightness to 600 nits; but it will drain enough power from the 4000mAh battery. When the brightness was tested under harsh light conditions the Samsung Galaxy M51 was the clear winner though the numbers are more on the Vivo V20.

OS and UI

Vivo V20 is one of the very few smartphones which run Android 11 out of the box and also has its Custom Funtouch OS 11 on top of the Android OS. A useful feature of the Funtouch OS is that enables the user to clone any application and lets them use the same application in two different windows with a different account on both. The applications of this feature are many. Consider a situation where you want to browse the social media(say Facebook) with two different accounts at the same time, App Cloning will help you do that very easily and effectively.

The Samsung Galaxy M51 runs Android 11 and will get Android 11 updates soon. The UI will get updated to One UI 3.0.

Performance: Gaming🔥🔥

Samsung Galaxy M51

The galaxy M51 is powered by the Qualcomm Snapdragon 730G octa-core processor. The G stands for gaming and this separates it from the Sd 730 processor. Though both the 730 and 730G SoC have the same Adreno 618 GPU, Qualcomm has confirmed that the Sd 730G has a 15% greater boost in the GPU performance than the Sd 730 SoC.

Vivo V20

The Vivo V20 has the Qualcomm Snapdragon Octa-core 720G SoC where G stands for gaming. It has the Adreno 618 GPU just like the Samsung Galaxy M51.

Verdict: Which is better

An Tu Tu benchmark shows that the 720G processor shows better performance than the 730G in real life resembling tests. It is true!! It can be seen that the 730G processor gets heated a bit faster than the 720G SoC and shows slight throttling and frame drops earlier.

But while editing videos on the 6GB RAM variant of Galaxy M51 and the 8GB variant of Vivo V20; the Galaxy M51 exported the video really quickly whereas the Vivo V20 took about 10 seconds extra to export the same file. So, it can be seen that Samsung has a better optimized processor and RAM than the Vivo V20 and is not inferior to Vivo V20 in performance. bot the smartphones show great performance and it both show varied performance levels depending on the task.

Bot the smartphones are good for games like COD and ASPHALT and both show the same settings. Even after long sessions of gaming both the smartphones became warm to a very small extent. This means that both the smartphones are good for gaming and Samsung M51 is better in editing and exporting videos.

Camera: Capture the moment

Selfie camera

Samsung Galaxy M51

The galaxy M51 has a 32MP f/2.2 Sony IMX616 sensor at the front for capturing beautiful selfies and video calls. It supports 4K video recording @30 fps and 1080p video recording @30fps with the front camera.

Vivo V20

It has a 44MP front camera which is the best selfie camera in this price range. It supports 4K video recording @30 fps and 1080p @30fps.

Which is best for photography?

Comparing the photos clicked on the Galaxy M51 and Vivo V20, the galaxy M51 captures photos with higher dynamic range but details are shown more on the Vivo V20 which is obvious. The Galaxy M51 produces a bit warm images whereas the Vivo V20 tends to whiten the skin tones. It is your preference; I personally like the warm images produced by the Galaxy M51.

Which is best for videography?

Again the Galaxy M51 shoots videos with a warm tone whereas the Vivo V20 tends to whiten the skin tones. The videos produced on the Galaxy M51 are better stabilized whereas the Vivo V20 shows no video stabilization.

Rear Camera

Samsung Galaxy M51

It boasts a intelligent quad rear camera system. Intelligent because of the Single Take feature which harnesses AI to produce the best shots out of the moment. It has a 64 MP, f/1.8, 26mm (wide), 12 MP, f/2.2, 123˚ (ultrawide), 5 MP, f/2.4, (macro) and a 5 MP, f/2.4, (depth). Samsung M51 boasts the Sony IMX682 sensor.

Which is better for Photography?

Photos caught on the Galaxy M51 look more natural and have better skin tones whereas Vivo V20 gives a white tone to the skin and does not look good always. Galaxy M51 has a macro sensor whereas Vivo V20 does not have one and Ultra-wide photos always look better on the Galaxy M51. Light exposure is also better controlled on the M51 without producing blown out images. Samsung Galaxy M51 clearly wins in rear cam photography.

Which is better for videography?

Clearly Galaxy M51 records slightly better stabilized videos with natural colors. Vivo V20 is not bad for videos but looses to the Galaxy M51 by slight points.

USEFUL Software features

Samsung Galaxy M51

The Galaxy M51 has the Single Take feature which is very useful for capturing memorable moments like birthdays and parties. The user gets multiple outputs in the Single Take mode just by pressing the button once and the AI will show 10 different outputs (7 photos and 3 videos) with different filters and effects applied. This feature makes video recording more fun and easy.

The user also can switch between front and rear cameras while recording videos which is a good feature. There is hyperlapse mode as well which is fun and cool. Hyperlapse feature opens a new door of creativity with so many possibilities.

Vivo V20

The Vivo V20 has an eye Auto focus feature on the selfie mode which is only available in many expensive cameras. this feature is very useful and locks the subjects automatically without having to do so manually. The Galaxy M51 does not offer this feature

Another special feature is that you can record videos with front and rear cameras at the same time. This feature is really great and cannot be seen in the Galaxy M51.

The final Verdict

To make it very clear let me tell you that Galaxy M51 produces human images which look more natural and eye pleasing whereas the Vivo V20 captures images which have a white skin tone which does not look good in every scenario. Moreover natural skin tones are better when it comes to editing photos. Both the smartphones have their own software features which are special. Details are more on the selfies clicked with Vivo V20 and more on the pictures clicked with rear camera of Galaxy M51. Videos captured with the Galaxy M51 look more better because of the image stabilization which is not done in Vivo V20.

Single Take feature is great and is very useful and fun. It will also help newb photographers to click some awesome photos and short videos. the outputs with this feature are amazing. The Dual video recording feature is also awesome and comes handy when your are going on a trip and recording vlogging videos. At times vloggers feel how nice it would be if they could capture videos with front and rear cameras at the same time. Well for them the Vivo V20 is a good choice.

For folks who mainly emphasize on photography and not vlogging, for them Galaxy M51 is the better choice among the two.


Samsung Galaxy M51

It comes in a single storage option and two RAM options: 6GB+128GB and 8GB+128GB. The storage is expandable via microSD card upto 512GB.

Vivo V20

It comes in a single RAM option and two storage options: 8GB+128GB and 8GB+256GB. The storage is expandable via microSD card upto 512GB as well.


Samsung Galaxy M51

The Galaxy M51 is the first Indian smartphone to pack 7000mAh monster battery which lasts about 2 days and comes with a 25W fast charger which completely charges in 2 hours. It is obvious that the large battery will make the phone a bit heavy and bulky, but the Samsung has perfectly distributed the weight and does not feel that heavy.

the Galaxy M51 supports reverse charging meaning that your smartphone can be used as a powerbank on the go. The USB type-C to C cable is given in the box for reverse charging.

Vivo V20

It has a 4000mAh battery which might last a day depending on your usage. The 33W flash charger completely charges the smartphone in an hour.


If you are someone who is into heavy gaming and don’t want to waste time on charging, even if it is one hour should go for the Galaxy M51. However if you do not need a longer battery life according to your usage and have sufficient resources and time to frequently charge your device then you can go for the Vivo V20 if you are satisfied with other aspects of the mobile. Don’t forget about the reversible charging feature on the Galaxy M51.


Samsung Galaxy M51

WLAN: Wi-Fi 802.11 a/b/g/n/ac, dual-band, Wi-Fi Direct, hotspot

Bluetooth: 5.0, A2DP, LE


NFC: Yes

Radio: FM Radio

USB: USB Type-C 2.0, USB Type-C to C

Bluetooth: 5.1, A2DP, LE


NFC: Yes (Market dependent)

Vivo V20 has the latest Bluetooth 5.1 version whereas the Galaxy M51 still has the Bluetooth 5.0. The device has a USB OTG cable in the box whereas the Galaxy M51 does not offer one. Since the Galaxy M51 supports reverse charging there is a USB Type-C to C cable in the box while the Vivo V20 does not have it.


Samsung Galaxy M51 has no haptics feature whereas the Vivo V20 has the haptics feature and gives average haptic feedback. Haptics is a feature which makes the keyboard on your smartphone or any other app icon in the UI feel like a button. When a key, link or icon is pressed the motor inside the smartphone creates a vibration which is called Haptic Feedback. This kind of fells great while typing and doing such stuff.

Multimedia and others

Though both the mobiles have loudspeakers, the Galaxy M51 has a bit louder volume than the Vivo V20. To be honest the sound quality of both the smartphones are below average and you will surely need to plug in your earphones to get the most out the audio. Both the phones have the 3.5mm Headphone jack.

Sensors are the same on both the smartphones with a single difference that the Galaxy M51 has side mounted fingerprint scanner whereas Vivo V20 has in-display optical fingerprint scanner. The side mounted scanner is quicker than the in-display one.

Bottom Line

I personally recommend the Samsung Galaxy M51 because it has a way better Display, equivalent performance, large battery and excellent cameras. It is true that Vivo V20 runs Android 11 out of the box but the galaxy M51 will soon receive update and get Android 11 too. The Funtouch OS 11 is really fun and offers many customization features. In terms of display Galaxy M51 is better, in terms of performance both are equal because of the better optimization and RAM management on the Galaxy M51. In terms of photography/videography; Galaxy M51 produces more natural photos with more details whereas the Vivo V20 whitens the skin tones and thus looses some of the details from the image. Selfies are more beautiful in the ones captured from Vivo V20. In terms of battery life, Galaxy M51 has no competitor in the market for now. Vivo V20 beats Galaxy M51 in aspects of relatively less importance like better in-hand feel, Bluetooth 5.1 and in-display fingerprint scanner. if you found any feature in the Vivo V20 that Galaxy M51 lacks then you should towards the Vivo V20 for sure.

Individually both the smartphones are great but the Galaxy M51 offers a bit more specs at the same price range. The Vivo V series is a little over-priced while the M51 is perfectly priced.
