About Samsung Galaxy S21 5G

The Samsung Galaxy S21 5G fits comfortably in the hand with dimensions of 71.2 mm wide, 151.7 mm tall and just 7.9 mm thick, weighing a light 170 grams. Its single‑slot SIM tray keeps the profile sleek, while the front is dominated by a vivid Color AM‑OLED panel measuring 6.24 inches across. The screen delivers a sharp 1080 by 2400 pixel resolution, bringing vivid colours and deep blacks to everyday content.

Under the hood, the device runs Google Android 11 and is equipped with 8 GiB of RAM, providing smooth multitasking and responsive performance. A 4 000 mAh battery powers the phone throughout the day, and when it needs a top‑up, the wired charging system supports up to 15 watts. Together, these specifications give the Galaxy S21 5G a balanced mix of portability, visual quality and everyday usability.

This variant

This variant steps up the internal storage to 256 GB, offering more space for apps, media and files compared to the base model’s unspecified storage option.

Aimed at the China/Hong Kong market (model SM‑G9910), it differs from the sibling SM‑G9910 128 GB version by doubling the onboard storage, and from most other regional editions (Korea, Japan, US, Canada, Global) by its CN/HK focus, while sharing the same core specs as the Galaxy S21 5G line.
