New SGS2 i9100 upgrade problem - lock screen not unlocking

May 24, 2012
When uprgading from 2.8.17 to 2.8.31

If you have lock screen security enabled with secured with PIN.

After upgrade, it won't take the PIN to unlock the screen. Will be testing with 2.9.7 to see if it also has the same problem later and will update this one.
