Overview

Experience Samsung's iconic clamshell foldable with the Galaxy Z Flip4 5G in vibrant Blue — 128GB, Unlocked (SM-F721ULBAXAA). The Galaxy Z Flip4 reimagines the classic clamshell form factor for the smartphone era — folding into a compact, pocket-sized square that opens to a full 6.7-inch FHD+ Dynamic AMOLED 2X 120Hz display for an everyday smartphone experience that fits anywhere. Powered by the Qualcomm Snapdragon 8+ Gen 1 flagship processor, Flex Mode for hands-free photography and video at any angle, FlexCam for spontaneous hands-free selfies and video calls, IPX8 water resistance, a versatile dual rear camera system, and 5G connectivity — the Z Flip4 is a sophisticated everyday foldable for users who want flagship performance in the most pocketable smartphone form factor available. Unlocked and compatible with all major US carriers.

Key Features

  • Compact Clamshell Foldable Design: The Z Flip4 folds into a pocket-sized compact square — dramatically smaller than any standard smartphone when closed — then opens to a full 6.7-inch display for a complete everyday smartphone experience that genuinely fits in any pocket or small bag.
  • 6.7-inch FHD+ Dynamic AMOLED 2X 120Hz Inner Display: Samsung's vivid FHD+ Dynamic AMOLED 2X inner display with ultra-smooth 120Hz refresh rate for fluid everyday scrolling, gaming, and media consumption at full smartphone scale.
  • Flex Mode & FlexCam: Flex Mode lets the Z Flip4 stand on its own at any angle for hands-free everyday photography, video calls, and content creation — FlexCam automatically activates the camera in Flex Mode for spontaneous hands-free shots without a tripod.
  • Snapdragon 8+ Gen 1 Flagship Performance: Qualcomm's top-tier Snapdragon 8+ Gen 1 processor delivers exceptional everyday performance, gaming capability, and camera processing in the compact clamshell form factor.
  • IPX8 Water Resistance: Water resistant to 1.5 metres for 30 minutes for confident everyday use in wet conditions — a meaningful durability achievement for a foldable smartphone.
  • Vibrant Blue Finish: Bold, eye-catching Blue colorway that makes the Z Flip4 a distinctive everyday style statement — one of the most recognisable and fashion-forward foldable smartphones available.

FAQ

What kind of warranty/guarantee do you offer?

At R3NEW, most transactions are backed by a 1-year warranty, covering technical defects and malfunctions, while every purchase includes a 30-day guarantee. Our warranty is designed to give you peace of mind, ensuring the reliability and longevity of your device.

What's the difference between the conditions? (Excellent, Good, EcoSave)

Great question! Let us break down the difference.

Excellent: Our Excellent condition devices offer a pristine user experience that rivals new units, boasting a flawless appearance with no visible scratches on the display or body. Each device undergoes rigorous testing to ensure it operates like new, giving you peace of mind with a full year of warranty coverage. It’s an ideal choice for those seeking near-new quality without the brand-new price tag

Good: Devices in Good condition are a great compromise between cost and quality. You might find a few minor scratches or slight nicks on the body or display, but these are purely cosmetic and don’t affect the device’s operation. We suggest using a case to bring its external appearance closer to 'like new.' Rest assured, every device meets our strict functional standards and comes with a one-year warranty for functionality

EcoSave: Opt for our EcoSave condition if you want to maximize value while minimizing environmental impact. These devices show visible signs of use, such as scratches or dents, which are purely cosmetic and can often be concealed with a case. Each device has passed our comprehensive functional tests and is backed by a one-year warranty, ensuring it works perfectly for you while also being kind to the planet.
