Further, I have created a completely separate Role (disabling all the permissions) for general public use and therefore strogngly not expecting the general users to access settings area etc.
Problem is the soft keyboard that loads for normal EditTexts that expect user to enter text (reference text etc) is providing the button to change "input options" and therefore users can access keyboard settings through that. So they can change language and all other settings from here and since the device is in KIOSK mode no back button and fully stuck in there.
Is there a standard way that can disable input options button in device soft keyboard?
Is there a way to disable the option that soft keyboard provide user to insert Emoji's ?
