How set zoom camera to max?

Question

I use code zoom to max:

Camera.Parameters p = mCamera.getParameters();
maxZoomLevel = p.getMaxZoom();
p.setZoom(maxZoomLevel);
p.set("zoom-speed", 1);
mCamera.setParameters(p);
mCamera.setParameters(p);
mCamera.startPreview();

Result:

And case: zoom to max of standard camera on my phone:

Why does my application set max zoom smaller than standard camera? How set zoom camera to max the same standard camera? Or Has other function increased zoom capability of the camera?

Answer 1

Your phone's camera app is zooming on the frame it's displaying rather than the camera itself is zooming. Is your app, zooming to certain level?
