About Samsung Galaxy Z Flip 4

The Samsung Galaxy Z Flip 4 folds into a pocket‑friendly slab measuring 71.9 by 165.2 by 6.9 millimetres and weighing just 187 grams, making it easy to carry while still offering a usable exterior screen. When closed, the device reveals a 1.9‑inch colour AM‑OLED panel with a resolution of 512 by 260 pixels, providing quick glances at notifications, time and other essentials without needing to open the phone.

Inside, the phone runs on Android 5.10.81 and is equipped with 8 gigabytes of RAM for smooth multitasking. Power comes from a 3 700 milliampere‑hour battery that supports wired charging at up to 15 watts, and the handset accommodates a single SIM card for cellular connectivity. These specifications combine to give the Galaxy Z Flip 4 a compact form factor paired with the performance needed for everyday use.

This variant

This variant is the Korean‑market Bespoke Edition of the Galaxy Z Flip 4, featuring TD‑LTE 5G support and 512 GB of internal storage. It launches with Android 12 (S), a newer OS version than the base model’s original Android release.

Compared with the other listed Galaxy Z Flip 4 models, it is the only Bespoke Edition sold in South Korea; the alternative Bespoke Edition targets China, Hong Kong and Taiwan. All other versions differ by region or carrier (Japan, United States, Canada) and by offering lower storage capacities (128 GB or 256 GB) or alternative special‑edition collaborations such as the Maison Margiela model.
