Venu Sq - CIQ error

I have developed WF, it is absolutely ok in the simulator for Venu Sq, but user reported for CIQ error immediately on start this WF.

I am not getting any errors via ERA tool.

Also, I have realised in the Eclipse when I run this WF for Venu Sq (Run as.. -> Run Configuration) Choose a Target SDK Version is switching from 3.1 to 3.2 automatically, but I keep minimal SDK 3.1 to make it compatible with older models. Can this be a reason like production version is 'compiled' for 3.1, but real device can work with 3.2 only?

Please advice!
