Samsung S4 Zoom Does Not Support Smooth Zoom Issmoothzoomsupported()==false

I've tried to handle ZoomIn/ZoomOut at 's4 zoom' device in my camera record application. Because it does support only regular zoom, i.e parameters.isZoomSupported()==true, paramete

Solution 1:

I have already found solution for Smooth control of Shutter lens on Samsung S4 Zoom device. Set device in smart mode: parameters.set("mode", "smart-auto");

For Zoom In start: parameters.set("zoom-action", "optical-tele-start");

For Zoom Out start: parameters.set("zoom-action", "optical-wide-start");

For Zoom action stop: parameters.set("zoom-action", "zoom-stop");

Shutter speed: parameters.set("zoom-speed", 1); //1,2,...

Don't forget save parameters in the Camera instance mCamera.setParameters(parameters);

This works fine in my device, shutter now is silent and smooth. :) Regards.

Solution 2:

Also, in order to get current zoom value, use this code:

            Parameters parameters = mCamera.getParameters();
            List<Integer> zoom_list = parameters.getZoomRatios();

            int val = 0;

            if(isSamsungS4Zoom){
                    //FOR S4 ZOOM
                    mZoomVal = parameters.getInt("curr_zoom_level");
                    val = zoom_list.get(mZoomVal);
            }else{
                    val = zoom_list.get(mZoomVal);
            }
