Samsung launches third folding device N?

Samsung is a strong leader in the folding smartphone industry, but may announce a new type of folding smartphone. Reported by the Galaxy Club in the Netherlands.
According to it, there are three codenames for Samsung folding devices this year: B4, Q4, and N4 .
B and Q are Flip and Fold that you already know. Initially, the Galaxy Z Flip was called by the development code of "Galaxy Bloom" which means flowering, and the code name of Galaxy Z Flip 3 was changed to "B3" from there. Also, the reason for the Galaxy Z Fold 3 is unknown

but it seems that it was named "Q3", and it is no wonder that B4 / Q4, which seems to be the successor to them, exists.
However , N is the first appearance. It is an unknown model.
However, of course, the form of this N4 device has not been reported.
The Galaxy Club says it's a notebook format that was featured on Samsung Display's site, which manufactures displays.

On the other hand, for reference, Samsung's patented folding device includes " Vertical folding smartphone equipped with a rotary camera " to " Galaxy Flex Note that folds across the S-Pen ", and TCL that combines folding and winding. A wide variety of models have been discovered, such as models similar to the "TCL Fold'n Roll" of the "TCL Fold'n Roll" and those with an L-shaped screen.

A device that holds a pen inside. The name "Galaxy Flex Note" has also been registered as a trademark.
