I have a Xperia Z5 Dual.
It has 2 accounts: Owner (which has a PIN lock screen), and another account for kids without screen lock.
After upgrading to Andoid 6.0. The owner account can not be unlocked. It keeps saying "Main Screen error, need to be closed", in general. The other account still work normally.
In additional, they finger print hardware is not recognizable also.
Please help.
