The major feature of Samsung Galaxy M21 is a massive 6000mAh battery. The front of the Galaxy M21 has a 6.4-inch FHD+ AMOLED panel and at back there is a triple rear camera setup with a 48MP primary lens. It has similar specifications to that of Galaxy M30s which is available in Nepal. The display looks good and it provides a better viewing angle as well as saturated color. The 6.4inch Super AMOLED Panel has an FHD+(1080X2340 pixels) resolution. The display itself is vivid and color accurate and has a teardrop notch to house a front-facing camera. The phone has a plastic frame and plastic back which might disappoint some of the users like lots of mid-range devices nowadays has a glass back. Galaxy M21 got Exynos 9611 10nm Chipset and a Mali G72 MP3 GPU. The octa-core CPU has quad high performing 2.3GHz cores and quad power-efficient 1.7GHz cores. The CPU and GPU coupling can provide adequate processing power to handle daily tasks like media consumption, surfing the internet, and watching youtube videos. But running high-end games and the graphic intensive tasks will limit the performance. Two variants of Galaxy M21 are available; one with a 4/64GB option and another with a 6/128GB option. This time Samsung used UFS 2.1 for faster storage technology. There is a triple rear camera setup at a vertical camera housing on the top left corner of the device. The primary 48MP f/2.0 camera is assisted by an 8MP ultrawide sensor and a 5MP depth sensor. Overall, these cameras can capture decent photos and videos but they are not of flagship quality. At the front, there is a single 20 MP selfie shooter embedded in a teardrop notch. Regarding video recording, Galaxy M21 can capture 4K video at 30fps.
The best thing about Galaxy M21 is that it got 6000 mAh battery, but the sad thing is it only supports 15W fast charging technology. Moreover, there is a rear-mounted fingerprint sensor in the Galaxy M21. Regarding connectivity, it supports dual-band Wi-Fi ( 802.11 ac), Bluetooth V5.0, GPS, FM Radio, Type C connector, etc. Additionally, there is a3.5mm headphone jack which comes in handy while listening to music.
