I'm pretty new to android development I don't know why the cell width isn't taken in consideration, on newer version of the flex window you can have multiple widget on the same screen.
here all widget are stuck on 4x4

Samsung seams to not use at all the target cell and want a fixed size for widgets, I'm not sure if there is a way to detect that you are on the cover screen and use onUpdate to have a fixed size only there

After looking at Samsung's documentation you linked: maybe it is because the Samsung-specific metadata XML is missing, have you tried adding that? (Looks like one XML could be used for all widgets as it has just one property.)

Closing in favor of #6127 that seems more active.
