Editorial note

The Samsung Galaxy A21s stands out with several advantages that make it an attractive smartphone. Its 6.5-inch screen, although featuring a resolution of 720 x 1600 pixels, provides an immersive visual experience for consuming multimedia content. The 48 MP rear camera allows for capturing good quality photos, especially for daily needs, and the 5000 mAh battery ensures impressive battery life, allowing for extended use without frequent recharging. However, this model also has limitations. The screen resolution may not satisfy users looking for high-definition display quality, particularly for watching videos or demanding games. Additionally, the 32 GB of internal storage may prove insufficient for users who download many apps or take a lot of photos, although it is possible to expand this capacity with a microSD card. In terms of performance, the Exynos 850 processor paired with 3 GB of RAM may show limitations when running multiple applications simultaneously or during intensive use. Finally, while the design is modern and sleek, the weight of 192 g may be perceived as slightly heavy during prolonged use. Overall, the Samsung Galaxy A21s offers a generally positive user experience, with notable strengths in battery life and photo capture, but it may not meet the expectations of those seeking higher performance or optimal display quality.
