Activator actions and lockscreen is not working. What could have caused this?

[iMore Question]

Hi!

When I restart my iPhone everything works fine. But after a while the following things stops working

- Single and double press on homebutton does nothing
- Sleep button makes phone flash and then locks the screen. If i press homebutton or sleep button after that it imediately unlock the phone without showing the lockscreen.
- Short hold on sleep button is assigned to setting in Activator but now nothing happends, also slide in from bottom left does nothing (is assigned to lastApp)

If i start the vitual home button by tripple pressing home button and then single press homebutton on the screen (via virtual home button) then nothing happens.
It seems like every Activator action involving starting apps or lock device wont work.

If I restart my phone or close all apps the problems goes away for a while but then the reappear. Does someone knows what could have caused this?

I would set up a Apple store Appt and have the device looked at.. I would also in the mean time try a full wipe and restore of the device.
