Galaxy S20 Ultra review: Camera is amazing but battery life and design aren't. Samsung's Galaxy S20 Ultra also has a higher-resolution 40-megapixel selfie camera, while the other two models have a 10-megapixel front-facing camera. The Galaxy S20 Ultra also supports 45W fast charging, but the official Samsung 45W charger will cost $50 extra. Excellent camera features aren't quite enough to overcome an awkward design, … The iPhone has a 12-megapixel selfie camera.
