As part of the world’s first water-resistant foldable phone line, the Samsung Galaxy Z Flip 4 is an engineering masterpiece that should appeal to content creators and travelers who prefer to pack light; its IPX8 water resistance rating allows for submergence up to 5 feet for 30 minutes. Unfolded, the 6.6-ounce Galaxy Z Flip 4 is 0.2 inches thick. When closed, it bulks up to 0.6 inches. The 1.9-inch, 260 x 512-pixel cover screen features the foldable’s most noteworthy upgrades, including additional widget controls, Samsung Pay support and the ability to launch calls. It even lets you reply to text messages without flipping opening your phone. Pretty slick. The Galaxy Z Flip 4 is packed with the latest Snapdragon 8+ Gen 1 chipset. According to Samsung, it has better NPU, GPU and CPU performance compared to its predecessor’s Snapdragon 888 processor. Samsung also claims that the Z Flip 4 has better modeling, a smaller hinge, and a bolder camera housing compared to the previous generation. What’s more, the aluminum frame is the Z Flip series’ toughest yet, so if you have butterfingers, the Z Flip 4 should be more resilient to the occasional drop. Still shopping?
