Design and Build
The Galaxy Z Flip 4 boasts a sleek, compact design that harks back to the classic flip phones of the past while incorporating modern technology. When folded, it’s small enough to slip into your pocket or clutch, making it incredibly portable. The phone features a glass back and a metal frame, giving it a premium feel that matches its high-end status. One of the standout features is its water resistance, with an IPX8 rating, meaning it can withstand being submerged in up to 1.5 meters of fresh water for up to 30 minutes. This adds an extra layer of durability, reassuring users that their device can handle accidental spills or rainy days. The renewed unit is professionally refurbished to ensure it looks and functions like new, though minor cosmetic imperfections may be present.
Display
At the heart of the Z Flip 4 is its stunning 6.7-inch Dynamic AMOLED 2X main display, which offers vibrant colors and deep blacks, perfect for streaming videos or browsing photos. With a 120Hz refresh rate, scrolling and animations are smooth and responsive, enhancing the overall user experience. When folded, the phone reveals a 1.9-inch Super AMOLED cover screen, which is larger than that of the Z Flip 3. This cover screen allows users to check notifications, reply to messages, and even run select apps without having to open the phone, adding convenience and functionality. However, the cover screen’s app support is limited, and the main display’s crease, while less noticeable than in previous models, may still be visible to some users.
Performance
Powered by the Snapdragon 8+ Gen 1 processor, the Galaxy Z Flip 4 delivers top-tier performance. Whether you’re multitasking between apps, playing graphics-intensive games, or editing photos, this phone handles it all with ease. With 8GB of RAM and 128GB of storage in the base model, there’s plenty of power and space for your needs, though those requiring more storage might look into higher variants if available. The renewed unit ensures that performance remains uncompromised, as it is tested to meet the same standards as a new device.
Camera
The camera system on the Z Flip 4 is designed to impress. The dual rear setup includes a 12MP wide-angle lens and a 12MP ultra-wide lens, both capable of recording 4K video at 60fps. The front camera is a 10MP sensor, but thanks to Flex Mode, you can use the higher-quality rear cameras for selfies by propping the phone up. This feature is particularly useful for group shots or when you want to take advantage of the better sensors. The camera performs well in various lighting conditions, with good dynamic range and color accuracy, making it a solid choice for photography enthusiasts. The renewed unit’s camera hardware is fully functional, ensuring you get the same quality as a new device.
Battery Life
Battery anxiety is a thing of the past with the Z Flip 4’s 3,700mAh battery, which is an improvement over its predecessor. Users can expect the phone to last a full day with moderate to heavy use, and with 25W fast charging, you can quickly top up the battery when needed. This means less time tethered to a charger and more time enjoying your device. The renewed unit’s battery is tested to ensure it meets performance standards, though battery health may vary slightly compared to a brand-new device.
Software and Features
Running on Android 12 with One UI 4.1.1, the Z Flip 4 offers a refined and user-friendly interface. One of the most notable features is Flex Mode, which allows the phone to be used in a half-folded state. This is perfect for watching videos, taking selfies, or even using the phone as a mini-laptop when paired with a Bluetooth keyboard. The cover screen can be customized with different clock styles, widgets, and even some apps, making it more than just a notification center. The renewed unit comes with the same software experience, ensuring you get all the latest features and updates available at the time of refurbishment.
Connectivity
The Z Flip 4 supports 5G for blazing-fast internet speeds, Wi-Fi 6 for improved wireless connectivity, and Bluetooth 5.2 for connecting to your favorite accessories. It also features NFC for contactless payments and a side-mounted fingerprint sensor for secure and convenient unlocking. While it lacks the ultra-wideband (UWB) feature found in some other high-end Samsung phones, most users will find the connectivity options more than sufficient for their needs. The renewed unit is fully tested to ensure all connectivity features work as intended.
Final Considerations
The Samsung Galaxy Z Flip 4 is a fantastic choice for those who want a stylish, innovative, and compact smartphone. As a renewed unit, it offers significant value, allowing you to experience premium features at a potentially lower cost. However, it’s worth noting that newer models, such as the Galaxy Z Flip 5, released in 2023, offer improvements like a larger 3.4-inch cover screen and updated processors. If you’re looking for the absolute latest technology, you might consider these newer options. For those who prioritize value and don’t need the latest features, the Z Flip 4 remains a compelling choice, especially as a renewed device. Be sure to verify the warranty, as renewed units typically come with a 90-day guarantee, which is shorter than the one-year warranty for new units.
