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

This variant is the US‑specific 512GB model that adds Ultra Wideband (UW) support and TD‑LTE compatibility, carrying the SM‑F731U designation (also referenced as SM‑F731A). Unlike the base description, it highlights the larger internal storage and the particular network bands enabled for American carriers.

Compared with other Galaxy Z Flip 5 5G versions, it differs from the US 256GB options (SM‑F731U1 and SM‑F731U 256GB) by offering twice the storage capacity, and from the Canadian 512GB version (SM‑F731W) by being configured for US networks and including UW capability. It also sets itself apart from the Korean Maison Margiela limited edition and the Japanese models by lacking special‑edition branding and targeting the US market exclusively.
