Frame Drop on Touching or Swiping Screen

Hello :-)

I get a 8-12 frame drop on my Galaxy Tab 4 (7.0) when I just touch and swipe on screen.

Even when the input is not effecting my game logic.

Without touching the screen my game runs at 60-54 fps.

• Using Unity 5

• It's a top down 2D Game.

• It has one Overlay UI - Canvas without clickable buttons.

• The camera has a rigidbody to manipulate its velocity and movement it

Any ideas?
