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”.
Xperia Lockscreen disabled by administrator error fix
Issue/Error: Not able to set lockscreen security settings as “None/Slide” back once you have set it to “PIN/Password”.
NOTE: Below posted solutions work for all Android devices running Lollipop.
Solution: There is a very simple solution for Xperia Lockscreen disabled by administrator error.
- Go to Settings > Security > Screen Security. Check whether you are seeing an error, as shown above, if yes then proceed as mentioned below.
- Under Security > Credential Storage > Tap on “Clear Credentials (Remove all certificates)” > Tap on OK.
After clearing credentials, credential storage security settings would look like as shown below.
- Once Credentials are cleared you can again set lockscreen security settings as “none/slide”
We hope this helps.
If you are still unable to set your lockscreen security settings to “none/slide”, let us know. Drop your comments below.

Thank u so much been tryin out for so long. 🙂
but doing all the above said the problem is still persist in Xperia Z1
Hello, as per your advise. I tried on “clear credentials” button, but the button is disable, greyed out.. 🙁 please advise on this
Lollipop lockscreen password does not have the security question feature Which was available in previous versions..
The main problem is deactivate the home screen function not the screen lock.
Thank u so much for this… I spent all night panicking wondering what I had done! Thank u so so much!
it work finally thank you very much dude
Awwwwwwwwesome!
Thank you very much! it worked finally…I have been trying to do all possible ways for past 3 days.
Thank you very much!
Thanks man, here written all is right.
Thank you
Many thanks getting ratty with it
It’s working! Thank you so much!
Does it clean all things on my mobile phone(photos,music,games…)?
No, everything remains same.
tnx 😉
Still trying to set the screen lock to none. I pressed ‘clear credentials’. It’s now grayed out. But there is still no option to set the screen lock to none.
I am having same issue with screen lock. I even powered off the tablet. Credentials is now grayed out and still can’t set screen lock to none. �off
Thankyouuuu so much.. Its work !
I locked my Z3 compact (after update to android 5.0) and i forgot pattern lock. B4 you had option “forgot patern (or password)” now what I can do apart from hard restart?
Type any password/pattern till it has reached its limit
And it should be showing “Forgot ur password”
Then click it
Is it something like that?
After updating to lollipop no social apps are connecting to Internet and hotspot in my Z1. Solution please
seems a firmware issue, try factrory resetting.
Are you sure? it will harm my phone?
Still trying to set the screen lock to none. I pressed ‘clear credentials’. It’s now grayed out. But there is still no option to set the screen lock to none. Only pattern option is coming with already set pattern. I had face recognition lock in my Z3 before updating to lollypop. I switch on smart locks but after completing all process of face lock, only pattern lock is coming in my screen. Very disappointed with update to lollypop. Can you tell me the solutions?

hello guys after clear the credential setting again the lock screen repeat plz help me wht can I do
My Z3 compact has the opposing issue. My lock screen pin keeps turning itself off and returning to swipe since last update….not very secure, and a pain in the a** to keep turning on again. Kinda defeats the object if i lose my phone anyone can just wait for the pin to reutrn to swipe without doing anything !!!!
Thanks dude it really help me
Still I have that problem
Please help me friends
Yeeyyy…it worked…ty aloot…you helped me…ty again…???

Clearing the credentials didn’t work for me, and when I tried the above method, I got to remove the password, but had to remain with “Swipe” as my option because “None” wasn’t available. I can live with that.
