Summary0029605: Samples, AndroidQt - Qt::AA_EnableHighDpiScaling display issue
DescriptionTo reproduce the issue:
1. Enable High-DPI with function:
QApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

2. Set window width and height with the Item's width and height, rather than with the device dependent width and height from function below:
   eglQuerySurface (anEglDisplay, anEglSurf, EGL_WIDTH, &aWidth);
   eglQuerySurface (anEglDisplay, anEglSurf, EGL_HEIGHT, &aHeight);

> 1. Enable High-DPI with function: QApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

This is not "enable High-DPI" - it is always enabled.
This enables "automatic" High-DPI, which should scale some QML controls "automatically".
