About Samsung Galaxy S10 5G

The Samsung Galaxy S10 5G presents a sleek slab of glass and metal that measures 77.1 mm wide, 162.6 mm tall and just 7.94 mm thick, fitting comfortably in the hand at a weight of 198 grams. Its front is dominated by a 6.66‑inch AM‑OLED panel that delivers vivid colours and deep contrasts, with a sharp resolution of 1440 by 3040 pixels that brings photos, videos and games to life. The device keeps things simple with a single SIM slot, ensuring straightforward connectivity for users who prefer a single line of service.

Under the hood, the phone runs Google Android 9.0 Pie and is paired with 8 GiB of RAM, providing ample headroom for multitasking and demanding applications. A 4 500 mAh battery sits inside, aiming to keep the display and processor powered through a typical day of use. As the model name suggests, this variant is equipped for 5G networks, offering the next‑generation mobile data speeds that Samsung’s flagship line promises. Together, these specifications create a balanced flagship that blends a large, high‑resolution screen with solid performance and endurance.

This variant

The Samsung SM‑G977U is the United States‑specific TD‑LTE version of the Galaxy S10 5G, equipped with 256 GB of internal storage. Unlike the Japanese and Korean models, it targets the US market, and unlike the US 512 GB variant it offers half the storage capacity.

It also differs from the other US‑market 256 GB model (SM‑G977P) by its model number, SM‑G977U, while sharing the same core specifications of display, RAM, battery and 5G connectivity as the base Galaxy S10 5G.
