I have a Galaxy S6 and today I let it do a system update to 6.0.1 because it prompted me. My device was encrypted and required my four digit pin to load up. After the update it no longer required the pin and loads directy in Android. Along with that the encrypt/decrypt is gone in system settings. Does anyone know anything about this? And how to get the phone to prompt for pin code when the phone is turned on or rebooted?
