Samsung Galaxy Z Flip 4

The Samsung Galaxy Z Flip 4 has a unique clamshell design that folds in half, making it compact and easy to carry around. It is made of durable materials such as Armor Aluminum and Corning Gorilla Glass Victus, and features an inner foldable panel with UTG technology. The device is available in four standard colors and can be customized through Samsung's Bespoke Edition service.

The camera module is located on the back of the device and includes a pair of 12-megapixel cameras and a 10-megapixel selfie cam.

The Samsung Galaxy Z Flip 4 has a 12MP main camera with a resolution of 4032 x 3024 pixels, which is 65% brighter than its predecessor. The primary camera takes sharp photos with striking colors and an ample amount of detail, and it performs well in low-light conditions. The phone features a new 12MP f/1.8 sensor with larger 1.8um pixels for the primary lens, which makes a huge difference in photo quality.

The camera app takes advantage of the phone's Flex Mode, which allows for a split-screen viewfinder and shooting controls when the phone is half-folded. The front-facing camera is a 10MP camera located on the inner display, which offers decent image quality, especially in well-lit conditions.

However, the phone does not have a telephoto lens, so zooming in at 3X or further may result in images that are less detailed compared to smartphones that have a dedicated 3X lens. Overall, the Samsung Galaxy Z Flip 4 is a great camera phone for those who prioritize low-light performance and flexibility in shooting modes.

The Samsung Galaxy Z Flip 4 features a 6.7-inch Dynamic AMOLED 2X display with a 2640 x 1080 resolution, HDR10+ support, 1,200 nits of peak brightness, and a variable refresh rate that scales up to 120Hz and all the way down to 1Hz. The cover screen is a 1.9-inch Super AMOLED display with a 512 x 260 resolution. The main screen looks outstanding with lusciously vibrant colors, excellent viewing angles, and it gets very bright when needed. The default vivid mode produces rich colors, but users can switch to a more neutral color profile and adjust the display temperature.

The cover screen displays notifications, lets users control music, set a timer, shows calendar events, and lets users reply to texts with voice. It can also be used as a viewfinder for the main cameras to get better quality selfies or take photos without unfolding the phone. Overall, the Samsung Galaxy Z Flip 4's display is suitable for users who prioritize a high-quality screen with vibrant colors and excellent viewing angles, as well as those who value the convenience of a cover screen for quick access to notifications and camera functions.

The Samsung Galaxy Z Flip 4 boasts a top-of-the-line Snapdragon 8+ Gen 1 chip, providing ample processing power for day-to-day tasks. It has 8GB of RAM, which is sufficient for juggling a handful of apps at a time, but may be limiting for heavy multitasking. The phone is available with storage options ranging from 128GB to 512GB, but unfortunately, it does not feature expandable storage.

The Z Flip 4 has excellent performance even when running demanding applications or multitasking, with apps launching instantly, menus scrolling flawlessly, and graphically demanding games playing without a hitch. However, the phone can heat up during more demanding tasks such as long gaming sessions or multiple hours of hotspot use.

The Samsung Galaxy Z Flip 4 has a battery capacity of 3,700mAh, which is an improvement from its predecessor. The phone has fast charging capabilities, with a maximum charging speed of 25W, and can be fully charged in around 80 minutes. The battery life can last a full day under regular usage, but heavy usage or certain features/apps may drain the battery faster.

For example, using the phone while paired with a smartwatch and wireless earbuds may require the Adaptive Battery toggle to be enabled and the Performance Profile to be set to 'Light' in the battery settings. The phone can run for between 22 and 26 hours per charge under normal usage, but the exact battery life may vary depending on the usage patterns and settings.

Overall, the battery performance of Samsung Galaxy Z Flip 4 has been significantly improved from its predecessor, but it may require charging throughout the day for heavy users.

The Samsung Galaxy Z Flip 4 runs on OneUI 4.1, a heavily-modified version of Android that offers a lot of customization options such as themes and widgets. The device also has an updated cover screen that displays notifications, battery percentage, weather, and the camera viewfinder, and allows users to add more widgets and set a custom background.

The Galaxy Z Flip 4 also has access to several features specific to it, such as Flex Mode, which takes full advantage of the folding displays. The phone has excellent multitasking capabilities and app management features thanks to its powerful processor and RAM, and runs on Samsung's fast and fluid One UI operating system.

It also has several security and privacy features, including Samsung Knox and a Secure Folder feature. The device enjoys Samsung's top-tier update policy, receiving four years of platform updates and five years of security patches. Overall, the Samsung Galaxy Z Flip 4 is a great choice for users who want a unique and powerful device with excellent multitasking capabilities, security features, and reliable updates.
