Samsung is realising a folding smart phone - the Galaxy Fold - in April.
It will work with 5G networks and cost almost $2,000.
It will also have specially designed aps that fit the new display.

"Some of the key features they touted was the ability to run three applications at once, which, right now, most smartphones can run two at most. Your iPhone can only run one at a time, so, you know, having true multitasking functionality is a really nice benefit there, and really just, again, that the design is really unique, and that comes a time when, you know, most of our phones are pretty boring-looking, and they're all they're all kind of rectangular slabs."
Along with the folding phone, Samsung also updated its decade-old Galaxy line, adding an edge-to-edge screen, new cameras, and a 5G version.
The company is still the global smartphone market leader with about 19 percent share.
Huawei and Apple are vying for second place, with about 13 and 12 percent respectively.
