About Samsung Galaxy S25 5G

The Samsung Galaxy S25 5G fits comfortably in the hand with a compact frame measuring 70.5 mm wide, 146.9 mm tall and just 7.2 mm thick, weighing only 162 grams. Its front is dominated by a 6.16‑inch AM‑OLED panel that delivers vivid colours and sharp detail at a resolution of 1080 by 2340 pixels, giving the device a bright and responsive viewing experience.

Under the surface the phone runs Google Android 15, branded as Vanilla Ice Cream, and is equipped with 12 GiB of RAM to keep multitasking smooth. A 4 000 mAh battery powers the device, replenished through a 15‑watt wired charger, while a single SIM slot provides connectivity for calls and data. These specifications combine to offer a balanced blend of portability, display quality and everyday performance.

This variant

This variant is tailored for the Japanese market, supporting TD‑LTE 5G bands and carrying the SCG31 carrier branding, while the base model’s description does not specify any regional or carrier details. It also ships with 256 GB of internal storage, a capacity not mentioned in the base model’s overview.

Compared with other Galaxy S25 5G versions, the SCG31 carrier suffix sets it apart from the otherwise identical JP models (SM‑S931Q/Z), and its 256 GB capacity distinguishes it from the 512 GB JP counterpart (SM‑S931J 512GB SCG31). Meanwhile, its Japan‑only focus differentiates it from variants aimed at Korea, Canada, the United States, Hong Kong/Taiwan, or global audiences.
