Why does my keyboard stay on my lock screen?

Turn off the iswipe function in your clean master app. It's a new function and it fixed it for me. When you open the app down in the very bottom right hand corner it says me. Click on that and then you'll see settings and you'll find it for letter. Good luck.

Amazing!!!! This was pissing me off sooo much! I owe you a few beers for that one!
 
The arrow option does not fix this issue. It was literally driving me nuts. Having to pull off the back and pull the battery, restart and then make sure not to have a text conversation open was a pain in the butt. Open Clean Master app, click on ME at the bottom of the opening screen, go to Settings and turn off the ISWIPE option. Fixed the issue quickly. Hope this helps.

you are a genius! And it has solved my problem. Thank you alwaysamanada81. My caps lock should demonstrate my gratitude!
 
Uninstall any new apps you installed before the keyboard problem occurred ... I uninstalled the new installed apps and it corrected the problem for me .. I have a Galaxy Note 5
 
I found that if you press the keyboard settings, the keyboard goes down. I have an SG5 Mini and the settings options is to long press the Emoji button
