About Samsung Galaxy Z Flip 5 5G

The Samsung Galaxy Z Flip 5 5G arrives as a compact foldable that measures 71.9 mm wide, 165.1 mm tall and just 6.9 mm thick, weighing in at 187 grams. It runs Google Android 13 out of the box and is equipped with 8 gigabytes of RAM, providing a responsive foundation for multitasking and 5G connectivity. The device supports a single SIM slot, keeping the design streamlined while still delivering the latest network speeds.

On the outside, a 3.39‑inch colour AM‑OLED secondary display offers a resolution of 748 x 720 pixels, giving users quick access to notifications, widgets and camera controls without opening the main screen. Power comes from a 3 700 mAh battery that can be replenished via wired charging at up to 15 watts, balancing endurance with the phone’s slender profile. These specifications define the core experience of the Galaxy Z Flip 5 5G, positioning it as a pocket‑friendly yet capable foldable option.

This variant

The SM‑F731U model is the US‑market version that adds Ultra‑Wideband (UW) capability to the TD‑LTE 5G radio, a feature absent from the base Galaxy Z Flip 5 5G and from the non‑UW US variant (SM‑F731U1). It also ships with 256 GB of internal storage, whereas the base specification does not define a storage size and the other US‑market models either lack UW (SM‑F731U1) or offer 512 GB (SM‑F731U with the V/A suffixes).

Compared with the Canadian (SM‑F731W) and Korean limited‑edition models, this US‑only device retains the same foldable form factor but is distinguished by its UW‑enabled TD‑LTE band and the 256 GB capacity, while those variants either omit UW or provide different storage amounts and regional firmware.
