How get the physical dimensions of the device?
I use QScreen, but it often gives is not the correct data. -
Have you tried to get dpi for the device first :
physicalDotsPerInchX : const qreal
physicalDotsPerInchY : const qrealalso you may compare or get the dpi of with the QWidget (if you use one)
int QPaintDevice::physicalDpiX() const
int QPaintDevice::physicalDpiY() constand multiply by the width/height of the device, widget or an item. If you want the size in metric/imperial you need to convert the values.

You should be careful with using this methods, in many android devices it gives you false information.
-
How about using Screen.pixelDensity? (with help of Screen.width, height, desktopAvailableHeight, desktopAvailableWidth of course)
-
I have used many ways, including android.util.DisplayMetrics.
And all they give the wrong dpi, so I can't find the diagonal of the device(
And qt methods wrong consider the pixels at the start of the program
