Best way to observe whether QML UI is working properly in extreme temperature surroundings?



  • Think of an App implemented using Qt with an UI implemented in QML for an Android or an iOS mobile Device.

    Mobile devices have different characteristics how they react to low or very low sorrounding temperatures, e.g. display is not as reactive as expected or touch events are not working properly.

    Is there a way to observe programmatically whether the QML user interface (or the overall app) is still reactive and working properly in such conditions?

    Is the refresh rate (frame rate) of the UI an indicator? Are there any other possibilities to determine from internal parameters whether an app is running properly.

    I would like to give the user a feedback in such cases or disable some time critical functions in the App to avoid mistakes.
