Hi,
Please compare your code from line 535 of CameraLauncher.java file:

Uri uri = Uri.fromFile(createCaptureFile(this.encodingType, System.currentTimeMillis() + ""));
bitmap = getScaledBitmap(sourcePath);

// Double-check the bitmap.
if (bitmap == null) {
    Log.d(LOG_TAG, "I either have a null image path or bitmap");
    this.failPicture("Unable to create bitmap!");
    return;
}

if (rotate != 0 && this.correctOrientation) {
    bitmap = getRotatedBitmap(rotate, bitmap, exif);
}

// Add compressed version of captured image to returned media store Uri
OutputStream os = this.cordova.getActivity().getContentResolver().openOutputStream(uri);
CompressFormat compressFormat = encodingType == JPEG ?
        CompressFormat.JPEG :
        CompressFormat.PNG;

bitmap.compress(compressFormat, this.mQuality, os);
os.close();

// Restore exif data to file
if (this.encodingType == JPEG) {
    String exifPath;
    exifPath = uri.getPath();
    exif.createOutFile(exifPath);
    exif.writeExifData();
}

// Send Uri back to JavaScript for viewing image
this.callbackContext.success(uri.toString());

Also, I am using cordova 6.1.0 version and camera plugin working fine.
