Sony recently rolled Android 5.0.2 Lollipop update for Xperia Z1, Xperia Z1 Compact, Xperia Z Ultra and Xperia “Z2” & Xperia “Z3” series. In the new Lollipop UI, Sony introduced many new features like material design UI, new Xperia Themes & Wallpapers, new settings & animations.

After updating to Android 5.0.2 Lollipop update many Xperia users are seeing this error “lockscreen disabled by administrator, encryption policy or credential storage“, even we got the same error once we were trying to set the lock screen security settings to “none/slide” from “PIN/Password”.

Issue/Error: Not able to set lockscreen security settings as “None/Slide” back once you have set it to “PIN/Password”.
