App opening motion disabled?

[AC Question]

I'm using an LG G4 and today I've noticed that when I open apps or exit them with the return button there isnt any visual effect, the screen just changes immediately instead of having a swaping like effect, its kinda hard to explain.
Anyway hope theres a solution for this
Thanks

Take a look in Developer Options, Animations.

I went on developer options and did reset to defaults and it worked, thanks a lot!
Do you know what caused this problem and what can I do to prevent it from happening again?
