iPhone 6s camera shaking constantly

Hello,

I just bought a iPhone 6s, and whenever I watch my recorded footage back, the camera is very shaky. When I'm filming, it's fine and very nice but when I stop recording and watch it back It's very shaky.

Here's a video:

Have you tried taking it back to where you bought it?
