Qlik Sense uses what Qlik calls intelligent responsive design. That means it will try to fit the content to the screen in such a way that it's most readable. That does not mean it will look exactly the same on all screens, just resized to fit. It means it can look very different. It will look radically different on a 'smallish' smartphone. You have no influence whatsoever over this.
I have make an application in qliksense and when i opened it in android Chrome browser, it's objects positioning was absurd. I have reduced the text object height and width to it's minimum but still in mobile , object's size is too long. Can you help me understanding how to align the objects in qliksense for mobile view?
