In the PIN PAD example above the (0) should be centered in the row as it
is already now in the lock screen. I have just entered too many leading
spaces there.

The number of digits to be entered as PIN should be at least 4.

When entering 112 and (/) the dialog should ask if it is intended to
dial an emergency call. But it should not do that too easy as I don't
like to dial 112 by accident when the mobile phone is just in my pocket.

Title:
  [System Settings] [design] allow Passcodes of variable length instead
  of just 4 digits

Bug description:
  Currently when setting a Passcode on the device, it must be 4 digits.
  This is artificially limiting. Other platforms (eg Android) allow
  longer Passcodes. It has always been my understanding that we should
  support Swipe, Passphrase and Passcode where Passphrase and Passcode
  can be arbitrarily long.

  However, once longer Passcodes are supported, we will have to add an
  Enter key. Right now, the lockscreen checks the Passcode once 4 digits
  are added so that you don't have to press Enter. I guess this was done
  for usability, but would be a security issue because an attacker can
  easily determine the Passcode length, which makes it easier to for an
  attacker to guess the Passcode. Eg, if I have a 5 digit Passcode set,
  then an attacker need only type '11111' and know that the Passcode is
  only five characters. Now, a Passcode isn't strong to begin with and
  an automated attack could rather quickly brute force Passcodes, but we
  shouldn't make it easier for someone manually trying to guess the
  Passcode.

  The passphrase lockscreen prompt correctly allows variable length
  passphrases and requires you to press Enter.

  I suggest moving the 'X' up t the left of '0' and an Enter symbol to
  the rigth of '0'.
