The year's biggest phone show, Mobile World Congress, often has some wild handsets -- here's the cream of the bizarre crop.

Lenovo’s new ThinkBook 3D Laptop Concept and Hybrid Dimensional 34-inch Curved Monitor Concept, announced at Mobile World Congress 2025, use directional backlighting and head tracking to simultaneously show 2D and 3D content without glasses. An accompanying AI Ring concept can be worn to control them with gesture-based spatial controls.

Mobile World Congress 2025 was a show about smartphones, and exciting ones too, which made it very different to the last few years. Here's more on the trend.

Along with first looks at what's coming soon to smartphone buyers, MWC also gives smartphone makers a chance to show off new concepts and design ideas.
