When I go to Settings->Accessibility, there are options to enable access for apps under Services.  However when I tried to turn them on, it pops up a question (different for each app) and offer answers of "Ok" or "Cancel".  I can only select "Cancel".  When I click "Ok" nothing happens.  

 

This problem exist for all apps.  

 

The phone has been updated to the latest firmware.
