Screen Lock - Can't get back to swipe

i have this issue with lock screen, couldn't disable it due to all grey out and clear credentials too. any solution for it?
 
Thanks very much! Clear Credentials un-greyed Swipe lockscreen for me on my Sprint Galaxy S5 G900P.04 running Android 5.0 Lollipop, version 'OK4 firmware. You rock!!
 
on the S6 edge plus, I went to

settings>lock screen and security>Other security settings>clear credentials

and it let me now choose "none" on the lock screen and security>screen lock type> none

interested if anyone thinks this might be bad, but it is working for me so far.

hope this helps! thanks!!
 
thnkx the problem is totally completely and easily solved by just going into settings/security/and just clicking on /"clear all credentials" and your problem will be solved hounestly im telling the truth

Thank you! This simple step helped me. I had android pay which made me put higher security lock on my phone. Then my bank stopped participating with android pay, so I uninstalled the app...but I was still stuck without being able to go back to swipe unlock.

Thanks Vaso. My granddaughter got hold of my S5 and I was stuck with entering a pin and nothing else to use the phone. I used your solution and now all is back to normal. Once again,Many Thanks.
