Is there a way to lock my home screen on my Note 4?

[AC Question]

I am not talking about locking the phone but the screen. Several times it has been in my pocket or even in my hand and I accidentally delete an icon or even a folder of icons that I have on my screen. It there a way (or an app) that I can make it ask for a PW before I delete an icon or folder? I put a bunch of things in folders and when one gets deleted, I am not sure which programs were in that folder to get back. Thanks.
