Cool, thank you!

Done. https://bugreports.qt-project.org/browse/QTBUG-39087
Any hints on the easiest way to workaround the issue?

>> 3. Combobox's auto-complete doesn't seem to be working on android (Qt

Ok, clear. https://bugreports.qt-project.org/browse/QTBUG-39088

>> 4. In general QML Components doesn't look very good on android. Is

Oh, ok. Do you know when it is planned to release this?
