This is my honest Samsung Galaxy M31 Prime Edition review.

The Samsung Galaxy M31 Prime Edition is launched on October 16, 2020.

Samsung Make in India strategy working out pretty well and seeing the number of rating and reviews on amazon they definitely want to make their sales graph all the way up to the sky.

My mother purchased this smartphone back at end of October 2020, just after when the product is launched.

The variant I have is 6GB RAM – 128GB storage, and it’s the only variant available.

You will be definitely saving 1000 rupees after reading this review, so please read thoroughly the review of,

Samsung Galaxy M31 Prime Edition

What’s in The Box

In the box of Samsung Galaxy M31 Prime Edition you get the following things:

  • Smartphone
  • Charger
  • Type-A to Type-C cable
  • SIM Ejector pin
  • Quick start guide

Design Need a Lot of Work

The design of the Samsung Galaxy M31 Prime Edition is nothing new, it’s the same polycarbonate you can find on its normal edition, the M31 normal edition launched back in February 2020.

The back panel is fingerprint and dust lover and I strongly urge you to use case protection and even after that you still face some dents, and you needed a wet cotton cloth to clean it.

Back panel

The Colour I have with me is blue, I don’t know what fancy name they made for this colour but it’s blue and shines more when you use the phone under direct sunlight.

Talking about the weight, I don’t know the exact number but feels somewhere around 190 – 200 grams, you can find the weight on gsmarena.

I must admit the weight distribution is great, even with the monstrous battery assembled inside you can still use the phone with a single hand and you don’t feel pain in your hand either.

The thickness is somewhere around 8mm now I don’t have the micrometer to measure but I guess it really doesn’t matter for a regular user.

Port and Speaker

The Samsung Galaxy M31 Prime Edition features a Type-C port at the bottom frame around it there’s a 3.5mm audio jack and a speaker grill.

Thumbs up for the Audio jack.

The Type-C port provides well-transferring data speed.

The speaker is loud and my mother every day plays Hanuman Chalisa and Shiv Mahimna Stotram in the morning. And vocal quality is good but the bass is not good.

Since my mother prefers to listen to old songs it’s not much of an issue, but I recommend you to use earphones for a much greater sound experience.

AMOLED Display Always

The Samsung Galaxy M31 Prime Edition features a 6.4-inch Full HD+ Super AMOLED display with a resolution of 1080 x 2340 pixels.

The colour reproduction of this panel is delightful and the panel is also Widevine L1 certified means you can stream OTT platforms content in HD and FHD resolution.

The brightness level is sufficient and I was able to use the mobile under direct sunlight without any hindrance.

The display of the Samsung Galaxy M31 Prime Edition is very slippery, what I mean by that is if you put the phone in a downward direction on a flat surface and if the angle of the surface is tilted then smartphone started to slip.

The display is touch response and for the easy access of tools, you also have this edge panel which my mother doesn’t really use.

Since there’s no LED-notification light I have to turn on the always-on display mode so my mother doesn’t have to miss any phone call or message.

Suppressed Performance

The processor inside the Samsung Galaxy M31 Prime Edition is Exynos 9611 octa-core chipset designed on 10nm architecture.

I was planning to do a separate gaming review of this phone, as I thought that gaming would be improved with the new Android 11 update.

But instead of telling the gaming experience in detail, I keep it short and simple for you if you’re an avid gamer.

Gaming on the Samsung Galaxy M31 Prime Edition is no good at all, to be honest. So forget it if you seek a gaming phone.

The RAM is 6GB and storage is 128GB UFS 2.1 and thanks to this UFS storage, most applications load quickly and phones’ performance is good on day-to-day use.

The One UI 3 based on Android 11 seems pretty heavy to me when I used some of the applications like camera, google pay and Instagram.

To summon up this section, I can say if you’re just after a regular performance like watching videos, multitasking, camera, calling, and texting then the performance is satisfied.

The Camera is 50-50

Samsung galaxy m31 prime edition camera lens details

Rear-Camera

The 64MP primary camera needs a lot of improvement after the Android 11 update. Here I am sharing some of the pictures which I take in direct sunlight.

64MP Lens

The image you see is without any adjustment, I haven’t tweaked any exposure settings but still, the whites in the images are not good, it may be happening because of the background.

The colour reproduction is good, at this price range you and I can’t expect anything to be perfect.

8MP ultrawide lens is somewhat appreciable as it maintains the skin tone colours and the details in the images look good.

8MP Ultrawide lens

The only thing in ultrawide that bothers me is that yellow effect but I hope to be fixed in the next update.

2MP depth sensor is good for taking portraits in daylight conditions. The edge detection, colour reproduction, and skin tones meet my expectation well.

Live Focus – Portrait

Another 2MP macro lens is completely useless, It lacks edge detection, and if zoom in fully the quality of the image isn’t sharp as it has to be. But I’d say just ignore the macro lens.

Rear-Video

This is where I lost completely my mind. At the price of Rs.17,000, many devices provide 1080p video at 60fps.

But this one gives 720p, 1080p, and even 4K at 30fps only, like why? And it affects the slow-motion mode very badly.

The Samsung Galaxy M31 Prime Edition has two slow-motion modes, slow motion and super slo-mo. 

Since the quality of super slo-mo and slow-motion at the night is bad, I tried using them in direct sunlight for better results.

What I get in results is 4/10. Pixelation is visible from the naked eyes and if your object moves too quickly then pixel drops can be calculated by pausing the video.

Samsung, we need a solid update for video recording.

Big Numbered Selfie

The 32MP selfie shooter of the Samsung Galaxy M31 Prime Edition provides good results in daylight conditions.

The issue I encountered is sometimes the edge detection is not good, but it occurs casually and the selfie camera is fantastic.

Zoom Till 10

The device has 2x optical zoom and 10x digital zoom and 10x digital zoom is not usable, look at the M letter in the below images, pixelation is visible.

However, 2x zoom is a different story here. The quality is on par and the image is sharp and has warm colours.

Night mode is The Best Performer in This Price

I was surprised by the night mode, photos taken in night mode are really good. Below here is a sample, taken outside of a restaurant.

Battery Life

The Samsung Galaxy M31 Prime Edition has a 6000mAh battery that lasts a day, I have rarely seen my mother plugging this device into charging.

But the 15W charger inside the box is similar to having a phone with a 4000mAh battery and a 10W charger. The charger does take nearly or more than 2 hours to juice up the battery.

Since the company hasn’t mentioned if it supports any extra fast charger I haven’t tested it with my OnePus 7T charger.

Verdict

The Samsung Galaxy M31 Prime Edition is nothing different than its predecessor model Samsung Galaxy M31 normal edition and remember I say I am going to save your 1000 rupees, this is it.

The Normal edition is 1000 rupees cheaper and has the same ditto specification as Samsung Galaxy M31 Prime Edition. The extra 1000 rupees you paying is for Prime word.

The Samsung Galaxy M31 Prime Edition is good for elder people or old age people who only prefer to use Samsung phones.

If your parents seek a budget smartphone under 20000 rupees gift this one they will be happy for the next 2 years.

Now, who should be not buying this smartphone? If you’re an avid gamer who likes to play heavy battle royale games then stay away. This game can run 2D games effortlessly and even 3D games but size and graphics play an important role.

Even if PUBG comes back in the upcoming time you can able to play that game at 60fps but after few minutes the device gets heat and games started to lag because it’s the same processor used in Samsung Galaxy A50s and I’ve experienced that one as well.

Who Should Buy It?
  • Media and Social media enthusiasts
  • Calling geeks
  • Business-class people
  • Camera like person
  • Old-age people
Who Should Not Buy It?
  • Avid gamers
