About Samsung Galaxy S20 5G

The Samsung Galaxy S20 5G presents a compact yet vivid 6.23‑inch AM‑OLED panel that delivers a sharp 1440 by 3200 pixel resolution, offering rich colors and deep contrast typical of Samsung’s display technology. Encased in dimensions of 69.1 × 151.7 × 7.9 mm and weighing just 163 grams, the device feels light in the hand while maintaining a premium glass‑and‑metal aesthetic.

Under the hood it runs Android 10 paired with a generous 12 GiB of RAM and 128 GB of internal storage, providing ample headroom for multitasking and apps. A 4000 mAh battery powers the phone, replenished through 15 W wired charging, and the handset supports 5G connectivity via TD‑LTE carrier aggregation, all while operating on a single SIM tray.

This variant

This variant is the United States‑specific model SM‑G981U, carrier‑locked to US Cellular under the SM‑G981R4 designation, whereas the base model description refers to the generic Galaxy S20 5G without any carrier or regional ties.

Compared to other US‑listed versions such as the SM‑G981P (Sprint), SM‑G981V (Verizon), SM‑G981A (AT&T), SM‑G981T (T‑Mobile) and the unlocked SM‑G981U1, this model is uniquely identified by its US Cellular branding and the R4 suffix, setting it apart from both the base model and its carrier‑specific siblings.
