I used 3 of the best flip phones, and the Z Flip 4 still rules
Summary
With the Galaxy Z Fold 4 and Z Flip 4, Samsung introduced a new hinge design that ditched the interlocking gears used for the previous generation models for linear, rotating components to reduce size and weight without affecting durability. The flat metal chassis has enough natural grip to it, plus a very subtle curve where there two sections meet means I can open it with minimal effort in a single, fluid motion. Let’s start with the Oppo Find N2 Flip and its Flexion hinge, which is shaped in a way that eliminates the gap between the two halves of the phone when it’s closed and reduces the visibility of the screen’s crease. It can hold the phone open at different angles, but there’s a lot more play in the hinge than the Z Flip 4, which affects the way it feels and reduces trust. All three phones are similar enough in price and specification to mean if you are interested in one, they should all be options (provided you live where all three can be purchased), and you shouldn’t be tempted to buy one where the big, reason-to-buy standout feature feels a bit rubbish.
