The Galaxy Z Flip8 is Samsung's clamshell foldable at its most polished, and also its most cautious. Almost everything that mattered about the Flip7 carries over: the same 6.9-inch inner screen, the same 4.1-inch cover display that runs full apps rather than widgets, the same 4,300mAh battery. What Samsung has done instead is shave the phone down. It is 8g lighter and thinner both open and shut, which counts for more than it sounds on a device whose whole appeal is disappearing into a pocket. The hinge opens more smoothly, and a titanium layer under the panel is meant to stop the crease deepening with age. UK models run the 2nm Exynos 2600, and that is where the real gain shows up: battery life is comfortably better than the Flip7's from an identical cell, though the compact body throttles hard under sustained load. The cameras are untouched, so photography is dependable rather than a match for slab flagships. Flip7 owners have little reason to move, but as a first flip phone this is the most sorted version yet.
