[Q] LG3 on-screen buttons topic

Hello Guys,
This is the first thread i am posting :)

Well i have a problem with my LG3 on-screen buttons
I gave the phone to my 3 years daughter.
When i took it back look what happened to my on-screen buttons
They changed to Rectangle, Square and Circle
Instead the regular ones...

How can i change it back??
Thanks! :)
