Last year i.e. from 2019, Samsung has strengthened its grip with the Galaxy M and Galaxy A series, changing the strategy for its Indian market. In this, the Galaxy M-series of affordable price has proved popular, in which the company has recently launched the Galaxy M21, which looks similar to the Galaxy M31 and M30s.

Samsung Galaxy M21 review: design and build

If we talk about the design of the phone, then this device looks very similar to the Galaxy M31 or similar to the Galaxy M30s launched before that. The phone feels very compact and lightweight when held in hand, which can be said to be a good thing for a large battery of 6,000mAH.


Redmi Note 9 Pro Max has also given you a 5,000mAh battery but it cannot be said to be as good as the Galaxy M-series.

The glossy plastic used in the phone gives a very inexpensive feel, which will be called a drawback, but it can be ignored when using the phone with a protective case or cover. The water-drop notch on the front side will also be called old in view of today's trend.

The Galaxy M21 has Gorilla Glass 3 protection on the front, along with attractive features like dedicated card slot, USB Type C port, and audio jack, etc. The fingerprint sensor is found at the back which is quite fast and accurate. This sensor is personally wireless to me from the optical in-display sensor given in the Galaxy A series.

Overall, the Galaxy M21 does not offer a special premium feel but it can be said to be better than the average due to the compact design despite having a larger battery.

Samsung Galaxy M21 review: display

The display has always been Samsung's specialty, and in this sequence, the Galaxy M21 gets a 6.4-inch AMOLED display with HD streaming support, which we cannot say about Xiaomi and Realme phones in this price range.

Not all AMOLED displays are the same. The display given in the Galaxy M21 looks a bit less than the Samsung Galaxy A51, but still, it can be said to be a good display for watching videos. In the display settings, you also get 2 color profiles as natural and vivid.

The display is not very bright, but in the outdoor, you can read text comfortably on the screen.

Samsung Galaxy M21 review: performance and software

Now let's talk about the performance of the phone. Simply put, the Galaxy M21 is not able to compete strongly with Xiaomi and Realme phones as the Exynos 9611 chipset is not designed for much gaming. Apart from gaming, you do not get any problem in the daily use of the phone.

You can play PUBG on the phone, but you will not like the performance. If you set the game settings to smooth - extreme then it looks a little right.

Samsung did not offer the 6GB model with the Galaxy M31 and that is why the Galaxy M21 has been introduced with 4GB RAM + 64GB storage. It has also introduced a variant of 128GB storage.

On the phone, you have been given OneUI 2.0 software with Android 10 which makes it much better than Realme UI or MIUI, but it can also be called a personal favorite. The software has a lot of custom features that come with an ad-free user interface.

The call quality is quite good in our area. The phone supports all basic connectivity as well as supports Bluetooth 5.1 and Wi-Fi calling.

Samsung Galaxy M21 review: camera performance

The Galaxy M21 has a triple camera setup at the back. Here the 48MP primary sensor is provided with 8MP wide-angle lens and 5MP depth sensor. Compared to the 64MP primary sensor of the Galaxy M31, a 48MP lens is used here.


In good light, the Galaxy M21 is capable of giving you better output with good details. Camera quality is very similar to the Galaxy M31.

Using a wide-angle camera, you can click nice shorts in daylight, but you will not use it much.

In low-light, the quality is a bit disappointing. In this case, the Galaxy M31 looks slightly better.

The 20MP selfie camera on the front gives good output but it appears only behind the Galaxy M31.

4K recording is supported in this, but for the best output, we would suggest using 1080 and super-steady.

Samsung Galaxy M21 Review: Battery & Audio

With a large 6,000mAh battery, you also get a power-efficient chipset due to which battery backup never proves to be a problem. Due to the corona-virus lockdown, we are using the device only in Fugger and it is able to easily backup 2.

In the box, you have been given a 15W fast charger but it cannot be said to be fast considering the battery capacity. It takes more than 2.5 hours to fully charge the device.

As far as audio output is concerned, bottom speakers give you much faster output, which is better than the quality average.

Samsung Galaxy M21 Review: Verdict

For starters, the Galaxy M21 offers a very similar experience to the Galaxy M31. But due to better low-light performance and selfie output, the price of the device seems correct.

It is clear that the online exclusive smartphones of Realme and Xiaomi give you a slightly better chipset, but they also have something that you do not find here like better software and battery backup.

The Samsung Galaxy M21 is generally capable of giving good competition to all phones in this segment. Also, the design and reason for the device also make it better.
