Samsung A51:

You really don’t get this kind of design implementation at this price as of now on the market. Samsung has brought it close to a flagship look on this phone with its punch-hole design. It’s like a galaxy note with a flat screen and of course punch hole towards the middle is always the best implementation.

When we look at the back of the phonem it comes with a beautiful look there as well. It is a glastic design, it’s not a true glass and I don’t mind that.

Samsung A70:

I think it’s not the most gorgeous looking phone I have seen at this price. It comes with 3D GLASSTIC panel which is a combination of plastic + glass. It looks so premium and super classy in hands. The front design itself is just amazing, you are getting super thin bezels just like the galaxy S10. The only difference is U-Notch.



Samsung A51:

I think the cameras are one of the best things about the device. And the optimization seems to have improved. You also get a new camera UI which looks more settle than it was.

Talking about camera specs, you get the same primary lens of 48 megapixel, then you have an improved 12 megapixel ultra wide-angle lens, 5 megapixel depth sensor as before, and an additional 5 megapixel dedicated macro lens.

The primary lens works just as good. The colors on it are punchy and the details are on point. What I like about Samsung devices is that they have the best optimization for skies and greenery.

Wide-angle images are sharp and have full of colors just like the primary lets you get nice colors in skies and greenery.

The edge detection in portrait is fairly good, under good lighting you can get some truly amazing portraits. The camera does smoothen the subject skin a little bit but the end result I must say is fairly good.

Samsung A70:

We’ve got three cameras to the back and let’s start with the primary sensor, this is a 32 megapixel sensor. Now most of the pictures are usually captured at 12 megapixels. The colors of the imaages are quite good. You can manually switch to 32 megapixels, if you want to and when you do that you end up getting more texture and detail in there but it does come at a cost and that cost is dynamic range this is because HDR doesn’t work when you are in the 32 megapixel mode.

That same rule applies to selfies too. We have a 32 megapixel selfie camera but if you want nice vibrant skin tones and a not so washed out background then you gotta settle for the lower resolution 12 megapixel selfies.

So getting back to the rear cameras, the secondary camera is an 8 megapixel ultra white and it gets some good shots. A different fresh perspective something unique and it has an F/2.2 lens here.

The third camera, it is a depth sensor, it helps with life focus, this is Samsung’s implementation of the portrait mode. And when it comes to selfie portraits, Samsung seems to do a reasonably good job differentiating between the background and the foreground.

Now moving on to low-light, the A70 kind of struggles, the pictures lack detail and often come out looking very dark. This seems to be a common Samsung issue. So hope that this is something Samsung can fix in the future.

There is support for 4k video but sadly no stabilization of any kind through the footage quality seems good.

A51 vs A70 - 2


Samsung A51:

It’s got a 6.5 inch Super AMOLED FHD+ screen. So it’s really colourful, crisp, and high contrast display. The outdoor visibility is also pretty good, so if you’re someone who is on the go and you keep watching videos or content or reading, you can depend on the phone’s screen when it’s really bright outside. It’s the first-punch hole display in the mid-range Galaxy A-Series.

Samsung A70:

This is one area that Samsung usually nails and they continue to do so here would be A70 because this is a 6.7 inch infinity U panel, this is a Full HD+ display, it’s got rich vibrant colors and even gets pretty bright under direct sunlight.

This have whidewine L1 here which means HD videos from Netflix and Amazon Prime shouldn’t be an issue.


Samsung A51:

For audio, loudspeaker quality is decent but this single speaker is nothing special. There’s a 3.5 millimeter audio jack on the A51 for headphones and actually quality here is great. There’s a lot of volume and not a lot of distortion.

Samsung A70:

The bottom firing speaker its output is a bit tinny but the sound output via the 3.5 millimeter headphone jack was excellent loud and clear even the in call speaker sounded good.

Samsung A51:

In terms of quickness and the phone’s overall performance, I never had a moment of major inconvenience or dissatisfaction with the phone in day to day use. When opening and running any of my usual applications despite this phone not having the latest and greatest flagship processor. Overall, this phone met all of my expectations I had for it in daily use which consists of quickly getting into the phone, watching YouTube, playing some games, checking emails, and browsing the web, texting and calling, and listening to music.

Samsung A70:

It has snapdragon 675 which was used in the xiaomi redmi note 7 pro almost at half the price and yeah this thing is really amazing in terms of the performance. I can say that it’s better than the note 7 Pro. But obviously not better than A51.

You can play PUBG at max settings without any legs or bugs and in terms of the daily usage it works flawlessly. There are no legs or hiccups. The RAM optimization is just incredible. But playing games for long-period of time, the phone become warm and then there are noticable frame drops.

A51 vs A70 - 3


Samsung A51:

This is world’s first mid-range phone to have latest android 10 out of the box. Samsung has themed this phone with OneUI 2.0. Apart from this new software, you get all the Samsung features like edge panel, night mode, dolby atmos, and the game launcher.

The only complaint about this software that there is no screen recorder. However, you can still record the games with game launcher app.

This phone also One-Handed mode which makes using this phone with one hand extreamly easy.

Samsung A70:

If I talk about software of this phone, it comes with Android 9 with OneUI. To be honest, this time Samsung comes with better optimised UI. Opening apps are pretty smooth and because of this you will see lag free UI. You will not get any issue in UI performance.



Samsung A51:

Battery-wise you get the same 4000 mAh battery on the A51 like that of the A50s. Pair that with an energy-efficient 10nm processor and a Super AMOLED display and the battery lasted for an entire day with moderate usage.

Samsung A70:

It comes with 4500 mAh battery with 25W super fast charging. You phone will charge from 0-100% in about 1 hour and 50 minutes. The battery lasted for about 12 hours with moderate usage. Also this device can be charged from 0-40% in just 20 minutes which will give you about 5 hours of backup.

A51 vs A70 - 1


The A70 has a bigger screen and it’s generally fast than A51. It also supports 25W fast charging. On the other hand, A51 has Android 10 out of the box, new design, and quad camera. Both the devices have in-display fingerprint sensor.

At the end of the day, it all comes to your personal choice, if you need a better display and good performance then you should go for A70. If you love to click images and you need a modern design then of course you should choose A51.
