Mobile World Congress 2024 was scheduled for February 26 to 29 at Fira Gran Via in Barcelona. Before the event, these were the devices and themes we expected to draw attention.
AI in phones and wearables
Phone makers were expected to add more AI features to cameras, health monitoring, and everyday device controls. The useful announcements would be the ones that solved a clear problem rather than adding AI as a label.
AR, VR, and metaverse hardware
More comfortable headsets, better tracking, and shared virtual environments were likely topics. Hardware weight, battery life, and software support remained the practical tests for these products.
Foldable and rollable devices
Foldable phones had already reached the market, while multi-fold laptops and rollable tablets were still newer concepts. MWC offered manufacturers a place to show which ideas were close to production.
Repairability and recycled materials
E-waste and resource use put pressure on manufacturers to discuss recycled materials, repair options, and power efficiency. Product details mattered more than broad sustainability claims.
Devices we expected to see
Lenovo's ThinkVision concept used a semi-transparent display with an AI overlay. Samsung's Galaxy Ring focused on health and fitness tracking in a ring. Motorola's Defy-X concept paired a rollable screen with a rugged design.
If you are comparing these previews with what companies eventually released, I recommend checking the final product specifications because concept hardware can change before it reaches buyers.
