We're using the embedded object 'application/x-systeminfo-widget' to access information about the device (language, RAM, vibration) and to provide hapatic feedback (through vibration).
In Symbian Anna, and older devices with the latest ROM update, this isn't working anymore.
All properties are returning 'Undefined' and setting vibration doesn't work anymore.
The Ovi apps approval process (QA) is reporting is doesn't work either in Nokia 5230 Firmware: V 10.0.067, 5800 Firmware: V 31.0.101 (works OK in v52.0.007).
BTW: It all works in previous firmware releases.
