I am new to AR and I have uploaded my image target on Vuforia which has 5 star rating. I am trying to put buttons in world space canvas. However, when I run the application on android platform, the gameobjects are very shaky. I have put gameobjects (button and canvas) as child of the image target. Here is a sample video of the final outcome.

The device that I am using has been mounted on tripod and still it is shaking.
