Who should buy which

Buy the Galaxy Z Flip8 if the reason for leaving an Ultra is weight and a phone that folds into a pocket, and you can live with a 4300 mAh typical battery, a hinge, and its 50 MP wide and 12 MP ultrawide cameras. Buy the Galaxy S26 Ultra if you still want the slab: the 200 MP wide camera, the telephoto cameras, the 5000 mAh typical battery, and Super Fast Charging 3.0.
