Description
Samsung Galaxy Z Flip4 F721U 128GB in Graphite — Wholesale B/C Stock
Built for enterprise, healthcare, and government device programs, the Samsung Galaxy Z Flip4 is Samsung's August 2022 clamshell foldable. It unfolds to a 6.7-inch Foldable Dynamic AMOLED 2X main screen (1080 x 2640, 120Hz, HDR10+) with a 1.9-inch Super AMOLED cover screen for notifications and quick replies. The Qualcomm Snapdragon 8+ Gen 1 (4 nm) runs with 8GB of RAM, and the dual rear system pairs a 12MP wide camera with OIS and a 12MP ultra-wide, with a 10MP front camera. A 3,700mAh battery supports 25W wired, 15W wireless, and 4.5W reverse wireless charging, and the aluminum frame and Gorilla Glass Victus+ back carry an IPX8 water-resistance rating. The phone weighs 187 g and folds to 84.9 x 71.9 x 15.9-17.1 mm. Samsung commits to four generations of OS upgrades and five years of security updates from the August 2022 launch; it launched on Android 12 and is upgradable to Android 16 with One UI 8. This lot is the SM-F721U (US carrier model) in the 128GB configuration, Graphite, carrier locked with the carrier not specified and graded B/C Stock.
Samsung's five-year security update commitment from the August 2022 launch runs into 2027, so this lot suits shorter-cycle deployments, loaner pools, and resale rather than new multi-year assignments; check the remaining window against your compliance policy. The foldable form factor suits executive assignment and customer-facing roles where a pocketable device and hands-free Flex Mode video calls are valued. An IPX8 rating supports rollout to healthcare and field settings where splashes and accidental immersion are expected; the Z Flip4 carries no dust rating, so protective cases are advised for warehouse use.
