Realme and Xiaomi showed off concept devices at Mobile World Congress that involve attaching a lens to your phone to get sharper shots. The concept phone has a physical connector that allows you to attach lenses directly to the phone itself. It lines up with the phone's internal 1-inch type sensor and allows you to use any full-frame mirrorless lens. Realme thinks pairing better optics with its phones' processing power will lead to better phone-based photos.
