Description
QScreen* screen = QGuiApplication::primaryScreen(); qDebug("============DPI %f(%f) %f(%f) dpr (%f)", screen->logicalDotsPerInchX(), screen->logicalDotsPerInchY(), screen->physicalDotsPerInchX(), screen->physicalDotsPerInchY(), screen->devicePixelRatio() ); qDebug("===========Physical size (%f x %f)", screen->physicalSize().width(), screen->physicalSize().height());
iPad Mini 1 (actual resolution 163ppi)
============DPI 72.000000(72.000000) 163.000000(163.000000) dpr (1.000000) ===========Physical size (119.676074 x 159.568098)
iPad Mini 4 (326ppi)
============DPI 72.000000(72.000000) 132.000000(132.000000) dpr (2.000000) ===========Physical size (147.781818 x 197.042424)
The physicalDotsPerInch is correct on iPad Mini 1 but not correct on iPad mini 4 (it should be 163 too)
Checking the code at https://github.com/qtproject/qtbase/blob/f40593b11199fbef886bfcb6b210a214d8c3adf3/src/plugins/platforms/ios/qiosscreen.mm#L180 it seems this value will also be wrong for iPad mini 2 and 3. Also probably for iphone 6 plus and iPhone 6S plus (both 401ppi native)
