About Samsung Galaxy Z Flip 5

The Samsung Galaxy Z Flip 5 folds into a compact form that measures 71.9 mm wide, 165.1 mm tall and just 6.9 mm thick, tipping the scales at 187 grams. When closed, a 3.39‑inch colour AM‑OLED panel serves as a secondary display, offering a resolution of 748 by 720 pixels for quick glances at notifications, time or widgets without needing to open the main screen.

Inside, the device runs Google Android 13 and is equipped with 8 GiB of RAM to keep apps responsive. Power comes from a 3 700 mAh battery that supports wired charging at up to 15 watts, and the phone accommodates a single SIM card for cellular connectivity.

This variant

The SM‑F731U model is the US‑specific version that adds Verizon’s UW 5G compatibility and ships with 512 GB of internal storage, whereas the base description does not mention storage capacity or carrier‑specific 5G bands. Aside from that extra storage and the UW modem, it shares the same screen, battery, RAM, Android version and dimensions as the standard Galaxy Z Flip 5.

Compared with the other listed Flip 5 variants, this unit stands out for its United States market focus and lack of any special‑edition branding—unlike the Maison Margiela or Retro Limited Edition models. It also differs from the US‑market 256 GB versions (SM‑F731U/SM‑F731T and SM‑F731U/SM‑F731A) by offering twice the storage, and from the Korean, Canadian, Japanese, Chinese/HK/TW and global models which are sold in those regions and often come with different storage options.
