Why changing wallpaper on phone while charging ?

[AC Question]

Everytime I connected the charger to my mom's phone it would change to beautiful wallpaper and on the bottom it would say slide to unlock then show regular lock screen. How do I disable and able it ? She has a Samsung s6 edge.

I think what you are describing is Daydream. Basically, it's like a screensaver on windows. Check Settings/Lockscreen or Settings/Display for Daydream.
