About Samsung Galaxy Z Fold4
The Samsung Galaxy Z Fold4 unfolds to reveal a large inner screen that measures 7.56 inches diagonally and uses a Color AM‑OLED panel, delivering a resolution of 1812 by 2176 pixels for sharp, vibrant visuals. When closed, the device is compact enough to fit comfortably in a pocket, with overall dimensions of 67.1 by 155.1 by 14.2 millimeters and a weight of 263 grams, making it one of the more manageable foldables on the market. Under the hood, the phone runs Google Android 12 (S) and is equipped with 12 gigabytes of RAM, providing ample memory for multitasking across apps and the flexible interface that the foldable form enables.
Powering the device is a 4,400 mAh battery that supports wired charging at up to 15 watts, offering a balance between endurance and recharge speed for daily use. Connectivity is handled through a single SIM slot, and the phone retains the 5G capabilities inherent to its model designation. Together, these specifications define a premium foldable smartphone that combines a spacious display with solid performance and a relatively slim profile for its class.
This variant adds a secondary Color AM‑OLED cover display, a feature not mentioned in the base model’s description.
It ships with 512 GB of internal storage, twice the capacity of the other US‑market model (SM‑F936U 256 GB) and matching the storage offered by the Korean and Canadian editions.
As the SM‑F936U model, it is tuned for US networks with UW TD‑LTE support, setting it apart from the Korean SM‑F936N and Canadian SM‑F936W versions.
Unlike the global dual‑SIM SM‑F936B/DS model, this unit retains a single SIM slot.
