The Galaxy Z Fold8 is not the phone the Fold7 turned into. It is a new shape entirely, and the one worth understanding before you buy. Instead of a tall, narrow phone that opens into a near-square tablet, this is a short, wide, passport-shaped handset that opens sideways into a 7.6-inch display in a 4:3 ratio. That sounds like a small change and is not. Films play with far less letterboxing, PDFs and web pages hold a sensible column width, and the 5.5-inch cover screen is broad enough to type on with two thumbs instead of the sliver you get on a conventional Fold. At 201g it is the lightest Fold Samsung has built, and charging finally moves to 45W, filling roughly two thirds of the 4,800mAh battery in half an hour. The compromises are real: there is no telephoto lens, and the redesigned hinge no longer holds itself open at an angle, so tabletop selfies and propped-up video calls are out. It is aimed at people who want a foldable for reading and watching, not for photography.
