About Samsung Galaxy W21
The Samsung Galaxy W21 stands out with its color AM‑OLED secondary display, stretching 7.59 inches across and delivering a sharp 1768 by 2208 pixel resolution. This screen sits alongside a compact chassis that measures 68 by 159.2 by 13.9 millimeters and tips the scales at 282 grams, balancing a generous viewing area with a hand‑friendly form. Powered by Google Android 10 and backed by 12 gigabytes of RAM, the device is primed for smooth navigation and responsive multitasking right out of the box.
Keeping the experience going is a 4390 mAh battery that can be topped up through an 11‑watt wired charger. Connectivity is handled via a single SIM slot, keeping the setup straightforward. Together, these specifications give the Galaxy W21 a distinct character, highlighting its secondary screen, solid performance, and practical power management in a relatively slender package.
