Editorial note

The Samsung Galaxy A21 stands out with a 6.5-inch display that offers a pleasant visual experience, ideal for watching videos and browsing the web. However, its resolution of 720 x 1600 pixels may disappoint demanding users, especially those looking for optimal display quality for high-definition content. In terms of performance, the 2.3 GHz octa-core processor ensures smooth and responsive usage, making the smartphone suitable for everyday use. The 4000 mAh battery is another major asset, allowing for prolonged use without frequent recharging, which is particularly appreciated by active users. However, the internal storage capacity of 32 GB may seem limited for those who download many applications or wish to store large multimedia files. Although expansion via a MicroSD card is possible, it may not be sufficient for all users. Regarding photography, the 16 MP rear camera and the 13 MP front camera allow for capturing satisfactory quality images. Nevertheless, the absence of a flash on the front camera can be problematic in low-light conditions, making selfies more difficult to take. Finally, the weight of 193 g may be perceived as a bit heavy, which could limit comfort during prolonged use. Additionally, the lack of water and dust protection restricts its use in challenging outdoor environments. In summary, the Samsung Galaxy A21 is a balanced smartphone, offering good performance and respectable battery life, but some aspects such as screen resolution and internal storage may not satisfy all users.
