Description

First time the camera is used it works fine. However, if the user cancels or tries to take another picture the camera screen is black. At this point it can take between 10-15 seconds before the camera preview appears and another picture can be taken. Have tried all version of the camera plugin starting at 0.2.5 (up to 0.2.9). Here is the code and device logs:

Here is the function... there are no errors logged in console when called:

app.takePhoto = function() {
        navigator.camera.getPicture(app.capturePhoto, app.onFail, { 
            quality : 20, 
            destinationType : 1, 
            sourceType : 1,
            encodingType: Camera.EncodingType.JPEG,
            targetWidth: 1024
        });
    }

var retries = 0;
    app.capturePhoto = function(fileURI )   {
        var win = function (r) {
            app.clearCache();
            retries = 0;
            $("#progressview").hide();
            app.showAlert("Your photo was successfully uploaded", "Photo Upload");
            var listview = $("#lsPhotos").data("kendoMobileListView");
            listview.setDataSource(app.photoDataSource);
            app.photoDataSource.read();
        }

        var fail = function (error) {
            if (retries == 0) {
                retries ++
                setTimeout(function() {
                    app.capturePhoto(fileURI)
                }, 1000)
            } else {
                retries = 0;
                app.clearCache();
                $("#progressview").hide();
                app.showAlert("The photo could not be uploaded to the server.  Please try again", "Photo Upload");
            }
        }
        $("#progressview").show();
        var fileUrl = "xxxxxxxxxxxx";
        var options = new FileUploadOptions();
        var prev_perc;
        options.fileKey = "file";
        options.fileName = mediaFiles[i].fullPath; // fileURI.substr(fileURI.lastIndexOf('/') + 1);
        options.mimeType = "image/jpeg";
        options.params = {}; // if we need to send parameters to the server request
        var ft = new FileTransfer();
        ft.onprogress = function(progressEvent) {
            if (progressEvent.lengthComputable) {
                var perc = Math.floor(progressEvent.loaded / progressEvent.total * 100);
                if(perc > prev_perc)    {
                    $("#progressview").text(options.fileName + ": " + perc + "% Uploaded");
                }
                prev_perc = perc;
            } 
            else {
                $("#progressview").text("Uploading Photo");
            }
        };
        ft.upload(fileURI, encodeURI(fileUrl), win, fail, options);       
    }

Click "Take Photo" button:

Immediately Click "Take Photo" again and the camera view appears with black screen
