Oppo X 2021 rollable phone hands-on

The Oppo X 2021 prototype rollable phone can switch between a conventional 6.7-inch screen and a mini-tablet-like 7.4-inch screen. This is achieved by rolling part of the flexible OLED panel into the back of the phone, which supposedly avoids the creasing issue we've seen on foldables. Despite the Oppo X 2021's second public appearance last month, the company still doesn't plan on mass-producing it. But as far as proof of concept goes, the rollable phone future is looking promising, save for the small kinks here and there.
