Galaxy S24 • Locked T-Mobile vs Galaxy Z Flip4 • Unlocked

The expected lifespan and software support differ significantly between these two Samsung smartphones.

• Software Longevity: The Galaxy S24 is set to receive an impressive seven years of OS upgrades and security updates, extending its support until 2031. This commitment ensures a prolonged period of new features and security patches. In contrast, the Galaxy Z Flip4 was promised four years of OS updates and five years of security updates, with support expected to conclude around 2027.
• Physical Durability: The Galaxy S24 features Gorilla Glass Victus 2 on its front and back, coupled with an Armor Aluminum frame and an IP68 rating for dust and water resistance, offering robust protection against daily wear and tear. The Galaxy Z Flip4, while also featuring an Armor Aluminum frame and IPX8 water resistance, utilizes Gorilla Glass Victus+ for its cover screen and back. Its foldable main display, however, has been noted by some users to show a more noticeable crease and potential for screen protector peeling over extended use.
• Practical Lifespan: Users prioritizing the longest possible software support and a traditional, highly durable build will find the Galaxy S24 more aligned with their needs. The Z Flip4, while durable for a foldable, presents a different set of considerations due to its unique hinge and flexible screen technology.

Performance capabilities are a key differentiator, influenced by the release dates and the processing power available at the time of their launch.

• Processing Power: The Galaxy S24 is equipped with a current-generation processor, allowing it to handle demanding applications, intensive multitasking, and graphic-heavy games with exceptional smoothness and responsiveness. The Galaxy Z Flip4, featuring a previous-generation processor, still delivers capable performance for everyday tasks, app usage, and most mobile gaming, though it may not match the S24's sustained peak performance in the most intensive scenarios.
• Multitasking and Storage: Both devices typically come with 8GB of RAM, providing a solid foundation for running multiple applications simultaneously. The Galaxy S24 offers storage options up to 512GB, similar to the Z Flip4, which also provides configurations up to 512GB.
• Battery Behavior: The Galaxy S24 houses a 4000mAh battery, which generally provides reliable power for a full day of moderate to heavy use. The Galaxy Z Flip4, with a 3700mAh battery, offered an improvement over its predecessor, but heavy users might find themselves needing to recharge more frequently, especially with prolonged screen-on time.

The display experience on these two devices offers distinct characteristics, primarily due to their form factors and display technologies.

• Display Technology and Clarity: The Galaxy S24 features a 6.2-inch Dynamic AMOLED 2X display with a Full HD+ resolution, providing clear and vibrant visuals. The Galaxy Z Flip4's main display is a 6.7-inch Foldable Dynamic AMOLED 2X panel, also with a Full HD+ resolution, which offers a larger viewing area when unfolded.
• Brightness and Refresh Rate: The S24 boasts a peak brightness of 2600 nits, ensuring excellent visibility even in bright outdoor conditions, and an adaptive refresh rate that scales from 1Hz to 120Hz for smooth scrolling and power efficiency. The Z Flip4's main display reaches a peak brightness of 1200 nits and also features an adaptive 1-120Hz refresh rate, providing a fluid visual experience.
• Unique Display Features: A key difference is the Z Flip4's foldable design, which includes a 1.9-inch Super AMOLED cover screen for quick notifications and interactions without unfolding the device. The S24 offers a traditional, flat display experience.

Both smartphones offer capable camera systems, but their configurations and capabilities reflect their different design philosophies and release timelines.

• Rear Camera Systems: The Galaxy S24 features a versatile triple-camera setup, including a 50MP main sensor with optical image stabilization (OIS), a 12MP ultrawide lens, and a 10MP telephoto lens with 3x optical zoom. This allows for a wide range of photographic options, from expansive landscapes to detailed zoomed-in shots. The Galaxy Z Flip4 comes with a dual-camera system, comprising a 12MP main sensor with OIS and a 12MP ultrawide lens. It lacks a dedicated telephoto lens, relying on digital zoom.
• Low-Light and Video Performance: The S24 generally delivers strong low-light performance, capturing detailed and well-exposed images in challenging conditions, and offers high-quality video recording. The Z Flip4 also provides good daylight photos and improved low-light capabilities compared to its predecessors, with decent video recording, though stabilization and autofocus may not be as robust as newer flagships.
• Front Camera and Unique Features: Both devices feature a 12MP front-facing camera on the S24 and a 10MP front camera on the Z Flip4, suitable for selfies and video calls. The Z Flip4's foldable design enables unique photography angles and the use of the main cameras for high-quality selfies via its cover screen.

Beyond core specifications, several practical elements contribute to the overall user experience of each device.

• Connectivity and Ports: Both the Galaxy S24 and Galaxy Z Flip4 support 5G connectivity, ensuring fast mobile data speeds. The S24 features Wi-Fi 6E and Bluetooth 5.3, while the Z Flip4 includes Wi-Fi 6 and Bluetooth 5.2. Both devices utilize a USB-C port for charging and data transfer, and neither includes a traditional 3.5mm headphone jack.
• Biometrics and Sensors: The Galaxy S24 incorporates an ultrasonic in-display fingerprint sensor for secure and convenient unlocking, alongside face recognition. The Galaxy Z Flip4 features a side-mounted capacitive fingerprint sensor, also offering reliable biometric authentication.
• Design and Handling: The S24 maintains a compact and traditional smartphone form factor, weighing 167g and measuring 147.0 x 70.6 x 7.6 mm, making it comfortable for one-handed use. The Z Flip4's defining characteristic is its foldable design, which allows it to fold into a compact square (84.9 x 71.9 x 17.1 mm) for enhanced portability, expanding to 165.2 x 71.9 x 6.9 mm when unfolded. This unique design impacts how the device is carried and used throughout the day.
