Oppo X 2021 rollable phone shows up in new hands-on videos Oppo X 2021

First came the foldables, and now it looks as though rollable phones could be the future of devices that start off at one size and then transform into another – and two new hands-on videos have arrived to showcase one rollable in particular, the Oppo X 2021.

As spotted by XDA Developers, several fresh YouTube videos have been posted online – including ones by Brandon Le Proktor in France and AllroundPC in Germany – giving us a detailed look at how the rollable mechanism works to expand the size of the screen.
