Hi @Fred_D4i,
What do you mean by "ThingWorx-based application shortcut" and "the application based on ThingWorx"? Do you mean mashup? Could you please elaborate on that?
> "when added to the home screen in Chrome, it still shows the browser bar."
↑ If you could provide a screenshot and point out what browser bar you are referring to would make others understand you better.
Maybe also provide a screenshot of Samsung IE which you expect how it should display for comparison.
Best,
