Tecno seeks to demonstrate that rollable smartphones are now closer to becoming a thing with the new Phantom Ultimate. The new prototype is capable of expanding its ~6.5-inch display into one of over 7 inches in diagonal length with "industry-leading unrolling speed" thanks to a range of engineering breakthroughs. It also supports more familiar, potentially welcome, specs such as a 1–120Hz refresh rate and an always-on display (AOD) mode.
