We tested the ideal smartphone with the ability to change the diagonal. But don't expect to buy one.

Over the past couple of years, we have seen quite rapid development in flexible display technology. Appeared and

foldable smartphones that turn into onemovement into a tablet, and devices with a screen on almost all sides (and even “folding phones” just in a new way).

- Hee-hee.

- The pupil increases 14 times, and hee-hee only one and a half.

The old joke plays with new colors when you get the OPPO X 2021 test.
