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‑F731Q runs Google Android 14 (Upside Down Cake) instead of the Android 13 found on the base model, and it is configured with 512 GB of internal storage while the base description does not specify a capacity. It is also marketed for Japan with UW TD‑LTE network support, a carrier and region detail absent from the base model overview.

Compared with the other Japan‑specific variants (SM‑F731J and SM‑F731D), which offer 256 GB, this model doubles the available storage. Unlike the US, Canada and Korea editions that target different markets and carriers, the SM‑F731Q is the Japan‑focused 512 GB option, sharing the UW TD‑LTE JP band with its JP counterparts but distinguished by its higher storage capacity.
