I published an update to a Qt/QML app and QA failed it for Symbian^3 devices only (passed S60v5). The reason they gave was that - "When launching the application by pressing the application icon, there is no response of the application."
I have no problems launching the application on the Symbian^3 device I have and the remote testing devices. The main change we have is that Qt Mobility is now used so I have a feeling it's a strange dependency problem although they even failed Belle devices which have everything pre-loaded.
I did use Qt 4.7.3 for S60v5 but that should still work on S^3 (I used it in the previous release).
Has anyone else experienced this problem and any ideas on how to fix it?
