    Default S4 screen lock disabled by administrator, encription policy or credential storage?

    I am looking for some help, I have recently purchased a Galaxy S4 everything seems ok with it but I can't change the screen lock from swipe. All of the options are greyed out and I can't select them. I have already tried unchecking the device administrators and resetting the security credentials but this hasn't helped. I have also tried restoring factory settings but still nothing, I would be grateful I anyone could give me some help. Thanks.

    I'm just going to throw this out there. Did you purchase this phone second-hand? If that is the case, it seems like the previous owner may have had this phone connected to his or her company's mobile device policy. Depending on how that company set up the policy, restricting screen lock is absolutely plausible.

    The phone was supposedly brand new from a bidding website but I'm starting to doubt it now. Is there any way to reset or get around these settings?

    Wipe and factory reset should have taken care of it. I would recommend following the Master Reset options posed by this site:

    If this does not work for you, it might be in your best interest to contact the seller.

    This may be too late but, since you have not updated this thread, here is another suggestion. From another thread with the similar situation, it was suggested to decrypt the SD card. Here is the link for your reference:

    I had same issue. I fixed it by removing a WiFi account that was using requiring a screen lock to be on the network.
    Try and remove any saved wifi accounts. Otherwise, some apps also require you too have a screen lock. This is done for security purposes.
    Hope this helps.

    I'm still stuck on this one. I've tried the following
    • Uncheck device administrators
    • Clear Credentials
    • Clear cache partition
    • Wipe data / factory reset, both from settings screen and recovery


    For some background here's how I got into this. I just upgraded my rooted phone from MK2 to NC5. I was connected to my exchange mail through the native android mail app. I also had FoxFi installed, which installs a certificate and was the reason I had a screen lock while I was running MK2. After upgrading to NC5, I can't enable a screen lock because all options are greyed. I do not have an encrypted sd card. I do not have saved VPN connections

    My was all greyed out except the pin lock, so what I did is go into settings, then into security, then into encrypt device, then select set screen lock type and from there you can select type of screen lock, so I selected swipe once you choose, select set screen lock type and it fixed it for me.
