About Samsung Galaxy Z Flip7
The Samsung Galaxy Z Flip7 measures 75.2 mm wide, 166.7 mm tall and just 6.5 mm thick, with a weight of 188 grams. It features a secondary Color AM‑OLED cover display that is 4.13 inches across and offers a resolution of 948 by 1048 pixels. The device supports a single SIM card.
Inside, it runs Google Android 16, also known as Baklava, and is equipped with 12 gigabytes of RAM for smooth multitasking. A 4300 milliampere‑hour battery provides the power, replenished via 15‑watt wired charging. Together these specs give the Flip7 a balanced blend of portability, screen utility and endurance.
This variant is tailored for the US market and adds dual SIM capability alongside support for 5G UW and TD‑LTE networks, while retaining the same core dimensions, display, OS, RAM, battery and charging specifications as the base model. It also steps up the internal storage to 512 GB, offering more space for apps, media and files compared to the base configuration.
Compared to the other listed global variant, this model is region‑specific to the United States, doubles the onboard storage to 512 GB versus 256 GB, and emphasizes 5G UW connectivity in addition to TD‑LTE, whereas the global version focuses on standard 5G and TD‑LTE without the UW band. Both share dual SIM functionality and the same 12 GB RAM configuration.
