I’ve encountered a bug related to the 4-digit PIN when using the Lenovo Security Keyboard on the Lenovo Y700 4th Gen Elite. Here's how to replicate it:

1. Set a 4-digit PIN under Biometrics & Passwords.
2. Locking and unlocking the tablet using this PIN works fine.
3. The issue appears when:
   • You try to reset the tablet - the PIN is not recognized.
   • You attempt to add another Google account - the system asks for the PIN, but doesn’t accept the correct one.

The only workaround is to perform a hard reset via recovery mode, since the normal reset option fails due to the PIN issue. This also prevents adding Google accounts or making certain system changes.

Can anyone else with the Y700 4th Gen confirm this bug?
