Movement in my galaxy s5.

AC Question

A couple of problems. First I've turned all the custom features off. I have something moving or fills like it's moving in my phone. Second, on my home screen sometimes when I touch it it goes to small plane and it does it sometimes when I don't touch it. If I touch one of the apps on the home screen it gets smaller the screen not the app. Then I have to touch the screen to get it back to full size before I can use my app.
