In a teaser video uncovered on Friday shows a foldable phone and the next-generation of its flagship smartphone, the Galaxy S10, and Galaxy Tab tablet computer.

Leaked by Samsung's Vietnamese subsidiary, the video was quickly taken down but appeared agian online bySlashleaks, a website specialized in aggregating tech leaks.

This leak comes less than 3 weeks before the technology giant's "Unpacked" event at the Bill Graham Civic Auditorium in San Francisco on February 20, where it plans to reveal these products ahead of the Mobile World Congress (MWC)

The video first shows an all-screen tablet with a stylus—Samsung sells the S Pen stylus that works with some of its high-end tablets and smartphones. The new tablet also looks wider and taller than Samsung's current flagship tablet, the 10.5-inch Galaxy Tab S4.

The video then goes on to show a woman in the night holding a smartphone which she unfolds outwards, just like when you open a book, and which automatically turns on the inner display.

Samsung has already showed off last October a prototype of its foldable phone concept with a similar clamshell design, but that one it looked much bulkier and thicker than the one on the teaser video. However, the front display looks much slimmer than the back one.

Finally, the video continues showing Samsung's next-generation flagship smartphone, the Galaxy S10. We could assume that thethe device shown in the leaked Samsung commercial is the entry-level model (S10 Lite), with an all-screen thin bezel "flat" display, with no curved edges, a dual-rear camera, and a mainstream fingerprint reader.

The Galaxy S10 is expected to feature an Infinity O display, smaller bezels, and a fingerprint sensor embedded into the screen. And according to recently-discovered FCC filings, the Galaxy S10 lineup will also come with latest-generation technology, including support for Wi-Fi 6.

Additionally, the device will also sport reverse wireless charging, a feature that we’ve already heard about earlier this year and which would technically allow the Galaxy S10 to charge other devices wirelessly.
