PIN Unlock removed after installing EHS on TC55. Bug or feature?

Hi all,


I am trying to get the EHS V1.4 configured on the TC55 for a customer project.

The customer wants to use the security setting in Android where a PIN is required to unlock the TC55 after reboot or period of inactivity.

I have setup this PIN (4 digits) under Settings -> Security within Android, so I am not using the default "swipe to unlock".


Now, when I install the EHS V1.4 and reboot the device after the .pdk was installed I have to enter my 4 digit PIN, which is good.

After entering the PIN the EHS is launched which I set as my default launcher. Fine so far.

Now I reboot once again and the PIN is gone. I can just unlock with a swipe.


When I go to the Settings->Security under Android I can see that the PIN has been removed indeed, which must have been done by the EHS application.

I have checked the XML configuration numerous times and the "Bypass Keyguard" option is disabled. Even when I turn the PIN back on it is removed again

after the next reboot.


So, is this a feature or a bug of the EHS and does anyone has any idea or tip how to overcome this?
