Galaxy A51 5G Review: Samsung’s cheapest 5G phone is a Strong buy

Galaxy A51 5G review: Samsung knew that the Galaxy A51 had to be a worthy successor to the Galaxy A50.

The latter was among its best-selling devices in 2019 and it would just be in Samsung’s pursuits to replicate that success in 2020. The Galaxy A51 managed to do that for the most part. It lived up to the anticipation of becoming a fantastic mid-range apparatus. But, Samsung had an ace up its sleeve in the kind of a 5G variant.

The Galaxy A51 5G is the cheapest 5G smartphone that Samsung sells. In some markets, it’s one of the very few and frequently the sole 5G device available in that price bracket. 5G compatibility on a device that’s already turned out to be a mid-ranger worthy of your cash. What is not to like?

There aren’t many noticeable differences between the LTE Galaxy A51 and its 5G sibling however, the few that exist merit a new review of the device. Let us dive into our Galaxy A51 5G review.

The Galaxy A51 5G looks exactly like the LTE version, no surprises there, however, there’s a subtle shift. Because this is a more”upmarket” version of the apparatus, Samsung has swapped plastic out from the framework for aluminum. This makes the device feel more premium in the hand and it is a welcome switch.

That’s just about it, though. Samsung has not swapped out the plastic material covering the trunk for glass so that you can forget about that. It has altered the prism-like crisscross pattern on the rear panel to favor clean lines to get a stronger colour profile. The L-shaped camera setup occupies exactly the exact same place at the back while the speaker, USB Type-C port and the 3.5millimeter headphone jack are placed at the base.

There are just three physical buttons and all of them are placed on the ideal side of the framework. There’s no dedicated Bixby key but if you press and hold the power button, then it will fire up the helper. This behaviour can be altered and the button can be configured to automatically deliver up the menu instead via the Advanced features menu in the Settings program.

It’s also heavier at 187g so you will definitely notice its heft, particularly in the event that you’ve employed the LTE one before. That being said, that the Galaxy A51 5G feels well constructed. It’s fully capable of withstanding the rigors of everyday use.

Galaxy A51 5G Screen

Both versions of this Galaxy A51 5G have exactly the exact same screen. It’s a 6.5-inch Infinity-O Super AMOLED 1080×2400 pixel resolution 20:9 aspect ratio screen with slim bezels. The viewing angles are all excellent and the panel becomes fine and bright even under direct sunlight. Colours are rich and vibrant with deep blacks depending on the quality of the panel.

An optical fingerprint sensor is embedded in the display. The operation has improved by leaps and bounds over the Galaxy A50. We did not experience the same struggles with fingerprint recognition as we did on its predecessor. It is good to see that Samsung has made amazing progress here and it gives us hope that these sensors will continue to improve in future models.

The camera section also keeps complete parity between both Galaxy A51 variants. There’s a 48-megapixel f/2.0 primary sensor at the back alongside a 12-megapixel f/2.2 ultra-wide and a 5-megapixel f/2.2 depth camera.

The Galaxy A51 was the first Samsung apparatus to come with a macro camera. That 5-megapixel f/2.4 sensor is present on the 5G version as well. A 32-megapixel f/2.2 front camera handles selfie duties. (Galaxy A51 5G review)

We’ve tested this camera setup in great detail so have a look at our Galaxy A51 review to learn more. TL;DR: The primary camera can capture nice, sharp pictures with true color reproduction and does a pretty good job in low-light states too.

Ultra-wide images have more detail but can end up looking softer in the dark. The macro camera is great at what it does, but because of its fixed focus, you have to nail the space to the topic so as to get a good photo.

Galaxy A51 5G software

It brings several new features such as Bixby Routines, App Pairs and Edge display. Bixby Voice is present as well. Focus mode, improved parental controls and Google’s navigation gestures are part and parcel of Android 10.

Samsung has attracted many of the Galaxy S20’s best camera features to the Galaxy A51 lineup with a single UI 2.1, including a full-fledged Pro mode with shutter speed controller and manual focus. Everything works as it’s supposed to and the software itself is quite stable overall without any difficulties with apps crashing or freezing.

Galaxy A51 5G functionality

The Exynos 9611 is just a higher-clocked version of this Exynos 9610 located at the Galaxy A50. We had a good idea about what to anticipate performance-wise when reviewing the LTE version of this gadget.

Things are a bit different for the Galaxy A51 5G. That’s because it is powered by the Exynos 980 instead. That is Samsung’s very own mid-range 8nm chipset with an integrated 5G modem. The handset is available with 6/8GB RAM and 128GB of internal storage.

It actually gets quicker UFS2.1 storage in contrast to UFS2.0 on the LTE version. The unit we tested has 6GB RAM.

Having analyzed both the LTE and 5G variants, we could say that there’s definitely a noticeable performance difference. It feels more eloquent, jumping in and outside of programs feels quicker and the occasional animation stutter or lag we experienced about the LTE model is not that frequent. (Galaxy A51 5G review)

Resource intensive games such as Call of Duty or PUBG can run on the greatest graphics settings with no problems. The LTE model was not a slouch but we’ve got to hand it into the Exynos 980, it merely makes the Galaxy A51 5G somewhat quicker, and nobody’s going to locate fault with that.

Galaxy A51 5G audio and call quality

There’s nothing new to report here, possibly, as the only bottom-firing speaker on the Galaxy A51 5G is as unimpressive as it had been on the LTE model. The sound is level and it’ll leave you wishing for more bass. The speaker clearly wasn’t on Samsung’s list of priorities for the Galaxy A51.

This seems like a missed opportunity because Samsung might have enhanced it about the 5G version but it chose not to. You do get basic wired cans in the box which will find the job done. (Galaxy A51 5G review)

There is Dolby Atmos service for Bluetooth and wired audio which can help enhance the sound experience marginally. There are not any complaints about the telephone audio. Calls come in fine and crisp with adequate volume in the very top end.

Given that it has support for 5G and that requires more power, the Galaxy A51 5G has a larger 4,500mAh battery compared to the LTE version’s 4,000mAh. You can expect a full fee from 0 to take just over two hours.

The Galaxy A51 5G can easily squeeze out a full day’s worth of use out of its battery. It usually lasts around an hour or so more than the Galaxy A51. You will obviously notice quicker battery drain when attached to some 5G network. (Galaxy A51 5G review)

These networks are still not omnipresent in many markets so the telephone frequently has to leap between 5G and legacy networks. That may take its toll on battery life but Samsung made the sensible decision of greater capacity so that Galaxy A51 5G owners can make it throughout the day.

Galaxy A51 5G verdict

We concluded in our overview of the LTE version that the apparatus was ideal in its reality. There is a lot that you get for its $399 price tag. The AMOLED display is exceptional, cameras transcend expectations and the system looks great also. None of that has been removed in the 5G variant. If anything, it has become more refined. (Galaxy A51 5G review)

The aluminum framework and the wash lines in the back make it feel much more premium. The Exynos 980 chip improves performance and service for 5G allows you to experience the next-gen network regular without burning a hole in your pocket.

The $499 Galaxy A51 5G is meant for a very specific market and it is obviously only going to be marketed in markets in which 5G networks are available. A customer who has the option to pick either variant would only pay the $100 premium for the Galaxy A51 5G since they wish to experience the faster mobile network. (Galaxy A51 5G review)

If you are that client, you’re unlikely to discover a smartphone that is as capable as the Galaxy A51 5G inside this budget. That is really what Samsung was counting on when it decided to deliver 5G compatibility to one of its most well-known devices. For customers in many markets, the Galaxy A51 5G may be the least expensive point of entry into the world of 5G. (Galaxy A51 5G review)

The Galaxy A51 quickly cemented its place for a phone that you can not go wrong with. It’s a terrific mid-range phone and with each of the improvements that the 5G variant brings, it has become much better. At this price, there’s no reason why you need ton’t get the Galaxy A51 5G.


  • Well constructed, aluminum frame
  • Outstanding Infinity-O AMOLED screen
  • Improved camera experience as a Result of new camera modes
  • 3.5mm headphone jack


  • Macro camera is a market thing
  • No 25W quickly wired charging
  • A Little on the hefty side
  • Speaker must have been improved
