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 Japan‑specific model carries the SCG23 carrier designation and adds UW TD‑LTE support, setting it apart from the standard Galaxy Z Flip 5 5G. It retains the same 8 GB RAM, 3.39‑inch secondary display, 3 700 mAh battery and 15 W wired charging as the base model, but offers 256 GB of internal storage. Compared with other JP variants, it matches the 256 GB capacity of the SM‑F731D model yet uses a different carrier code (SCG23 instead of SC‑54D), and it differs from the 512 GB SM‑F731Q version by providing half the storage.
