Samsung's Galaxy M series was introduced as an online-exclusive lineup to compete with Chinese manufacturers such as Xiaomi and Realme. The devices introduced as a part of this series have gained a lot of popularity thanks to their aggressive pricing compared to Samsung's other offerings. Thanks to their popularity, these smartphones are now also available offline. Samsung recently added another model to this series, called the Galaxy M21. This new smartphone shares a lot of hardware with some of its predecessors but can it stand out? We put the Galaxy M21 to the test to find out.

Samsung Galaxy M21 Summary

The Samsung Galaxy is yet another smartphone to join the Galaxy M series. It brings some of the key features that the Galaxy M series is known for. The smartphone packs in a 6.4-inch AMOLED display that isn’t very common at this price point. It has a vivid output and very good viewing angles. Samsung has made the Galaxy M21 out of plastic to keep the price of the smartphone in the affordable segment. The highlight of the Galaxy M21 is the massive 6,000mAh battery that helps it deliver great battery life. One downside is that the charging time is longer which could get annoying.

Powering the smartphone is an Exynos 9611 SoC that is capable of delivering decent performance. It is available in 4GB and 6GB RAM variants. It also comes in 64GB and 128GB storage variants. The Galaxy M21 sports a triple camera setup with the highlight being the 48-megapixel primary scanner. The camera clicks good photos during the day but low-light camera performance takes a hit. Video performance is below average. Overall camera performance is below average compared to the other phones at this price.
