    Description

      I get incorrect window size and DPI values for Android on two different phones (Android 9 and Android 13). So far I've tested with Qt 6.5.0, 6.4.3, and 6.3.2 and they are all wrong, however in Qt 5.15.3 there was no issue so I suspect this is an issue with Qt 6.

      For my phone with screen 1080 x 2246 pixels (DPI 216) the QScreen reports a size of 360x671 with a DPI of 72 for all above listed Qt 6 versions.

      No such issues on Windows deployment.
