Motorola Razr 50 Ultra

The Razr 50 Ultra has the best cover screen of any flip phone — a 4-inch panel that runs any app properly, so you often never open the device. Folded, it genuinely fits a small pocket. The inner 6.9-inch display is large and smooth. Battery life is the usual foldable compromise, and the cameras are good rather than flagship. If you have been tempted by a flip phone but worried about the outer screen being a gimmick, this is the one that answers that objection.
