Transition on input:focus and android keyboard



I’m experimenting some animation on input:focus and I’m facing some problems on Android.
I tried this animation:
Input:focus animation

It works fine on iOS but on Android, the moment I click on the input, the animation starts but the keyboard comes in and the input animation is stopped. And if I click on the other input, while the keyboard is up, the animation does not even start.

Have someone faced this issue?
