OnePlus is having quite an eventful Mobile World Congress. In addition to revealing its latest experimental phone that it envisions to have liquid cooling capabilities, the company has also announced that it will be launching its first foldable smartphone in the second half of 2023. With this revelation, OnePlus has confirmed previous rumors that it's working on a foldable device similar to Samsung's offerings. The company teased a mysterious Q3 2023 launch with what seemed to be silhouettes of devices that fold in the background at the OnePlus 11 event earlier this month, but it fell short of saying what exactly it would be releasing.
