Design and Display

The slot configuration offers dual nano-SIM slots and the memory can be expanded up to 512 GB via a MicroSD slot.


The camera configuration on the Samsung Galaxy M21s is one of the main highlights of the phone. The rear triple camera setup consists of an extraordinary 64 MP primary camera, along with a 5 MP depth sensor and an 8 MP (123 degrees) ultra-wide-angle lens for clicking the sharp and clear images.

Single-shot mode, ultra-wide mode, and night mode are some of the beneficial features. 4K recording is provided with the LED flash. To click on amazing selfies, the Front Camera with 32 MP is present.
