Samsung Galaxy M21 is an Android-based mid-range smartphone launched by Samsung Electronics as part of the company's 2020 Samsung Galaxy M series. The device debuted on March 18, 2020, succeeding the Samsung Galaxy M20 and Samsung Galaxy M30s. Initially shipping with Android 10 coupled with Samsung's proprietary One UI 2.0, it has since been updated to run on Android 12 featuring the enhanced One UI Core version 4.1.

Following its release, an upgraded variant named Samsung Galaxy M21s was introduced on November 6, 2020.

Hardware

The smartphone sports a 6.4-inch Full HD+ Super AMOLED display characterized by curved edges, a screen-to-body ratio of approximately 91%, and a tall aspect ratio of 19.5:9. The front panel is safeguarded by Corning Gorilla Glass 3 for added durability. On the back, crafted from polycarbonate plastic, a fingerprint sensor is conveniently positioned for biometric security.

Its camera configuration closely mirrors that of the Samsung Galaxy M30s, comprising a triple rear camera setup:

• Primary sensor: 48 MP with a f/2.0 aperture, pixel size of 0.8 μm, and an 80° field of view
• Secondary ultra-wide lens: 8 MP with f/2.2 aperture, pixel size of 1.12 μm, covering a wide angle of 123°
• Depth sensor: 5 MP with f/2.2 aperture for enhanced portrait effects

The front-facing camera is embedded within an Infinity-U notch and features a single 20 MP lens with an f/2.2 aperture and a focal length equivalent to 26 mm. Video capture capabilities include up to 4K resolution at 30 frames per second via the rear cameras and full HD (1080p) at the same frame rate using the front camera.

Powering the device is a substantial lithium polymer battery rated at 6000 mAh capacity, which supports adaptive fast charging at up to 15 watts through a USB Type-C interface.

Software

This device is equipped with Android 10 and Samsung’s proprietary One UI Core 2.0 interface. It was upgraded to One UI 3.0, based on Android 11, on 27 January 2021, followed by the One UI 3.1 update on 31 March 2021. Additionally, the phone is included in Samsung’s commitment to provide software updates for a minimum duration of four years for all smartphones launched after 2019. However, it remains uncertain whether this promise of extended security patches will also encompass future major Android version upgrades as per Samsung’s current disclosures.
