Our take on the Samsung S21 5G 128GB

The Galaxy S21 5G is Samsung's 2021 flagship phone with a 6.2-inch screen, a Snapdragon 888 processor, 8GB of RAM and 128GB of storage. Its triple rear camera (12MP main, 64MP telephoto, 12MP ultrawide) and 10MP selfie camera still hold up well, and the 120Hz display feels smooth. It suits buyers who want a compact, fast Android phone with strong zoom and video for less than current flagships. Against newer rivals it lacks a charger in the box, has no microSD slot, and its plastic back and battery life draw more criticism than the S21 Ultra's.

Is the Galaxy S21 5G still worth buying?
Yes if you want a compact, fast Android phone with strong zoom and video. Newer flagships beat it on battery and charging speed.

The phone comes in an OEM box with a generic USB cable and charger. Samsung does not include earphones.
