<div>just did a short test (Qt 5.7, QuickControls2 APP)<br>
<br>
tested Android 6.0.1 on BlackBerry PRIV:<br>
orientation change works between Portrait and Landscape<br>
but from Landscape to InvertedLandscape or from
InvertedLandscape to Landscape there was no signal<br>
for me no problem - don't have to distinguish<br>
InvertedPortrait couldn't be tested because my device
doesn't allow this<br>
<br>
tested on iOS 9.3 (iPhone 6s)<br>
all signals are coming in<br>
<br>
ciao<br>
