About Samsung Galaxy S23
The Samsung Galaxy S23 arrives as a compact flagship, measuring just under 147 mm tall and 71 mm wide with a slim 7.6 mm profile and a light 168 g frame. Its 6.06‑inch AM‑OLED panel delivers vivid colors at a Full HD+ resolution of 1080 by 2340 pixels, fitting comfortably in the hand while still offering plenty of screen real estate. Encased in Samsung’s Diamond DM1 finish, the device supports 5G UW TD‑LTE connectivity for US networks and ships with 256 GB of internal storage.
Inside, Android 13 (Tiramisu) runs on 8 GB of RAM, providing smooth multitasking and app performance. Power comes from a 3 900 mAh battery that can be replenished via 15 W wired charging, and the phone relies on a single SIM slot for cellular service. Together, these specifications give the Galaxy S23 a balanced blend of portability, display quality, and everyday endurance.
This SM‑S911R4 edition is the United States‑spec 128 GB version of the S23, identified by its unique model code and positioned as the only US variant with half the storage of the other American models, which are offered at 256 GB. It shares the same 8 GiB of RAM and single‑SIM layout as its siblings, but its lower capacity distinguishes it from both the US 256 GB builds (SM‑S911A and SM‑S911T) and the Chinese 512 GB configuration.
