I have upgraded my Sony Xperia Z1 from Android 4.4.4 to Android 5.0.2 and now, when the screen is locked, I first have to swipe before I can enter the pattern. When I go to Settings -> Screen Lock, there is an option None, but it is greyed out because of

Disabled by administrator, encryption policy, or credential storage

What does this mean and how can I change this?

  • Are you rooted?

You have set a custom VPN, encrypted your phone or something else that requires a lock screen on your phone. To disable that you will need to decrypt, remove your VPN's to get only a swipe lockscreen back.

On Android Lollipop, Google has added the swipe-up before you can enter your pattern. I don't know why the did that, but they found that usefull.

Hope my answer helps!

  • Thanks for your answer. I have indeed once set up a VPN, but by default I am not connected with it. I find it hard to believe that these two things are related. I have not encrypted my phone (I think). Jun 29, 2015 at 15:26
  • @physicalattraction if you are rooted you van remove the lock screen even if you have a vpn.

  • What does "rooted" mean? If it is a deliberate action on my side, then I didn't do that. Jun 30, 2015 at 12:42
  • @physicalattraction take a look at this: en.wikipedia.org/wiki/Rooting_(Android_OS)

  • Thanks! I don't have my phone rooted. Are you saying my phone needs to be rooted to bypass the swipe screen? Seems far fetched to me. Jul 3, 2015 at 7:24

You need to go to: settings; security; credential storage. And then clear credentials and then you can activate unlock by swipe
