Why does this show up in the lock screen menu for all lock screen options except for pin pattern and password? I have a screen shot but don't know how to post it from a phone. I cleared the storage credentials and it fixed it but why does this happen? Also any problems with clearing the storage credentials?
Go Settings > More > Security and scroll down. There should be heading called "Device administration"
If there is any checked boxes, you should be able to uncheck them and remove the PIN lock after that.
Today I again had to reset my credentials on my S6 so I could select None for security lock, as follows:
2. Lock screem and security
3. Other security settings
4. select "Clear credentials"
5 Go back to screen type and then choose the new security setting, i.e. None, fingerprint, swipe, pin, etc.
