This code will help you to store image im right rotetion.

final Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length, opt);
        final Matrix matrix = new Matrix();
        if (Utility.isTabletDevice(mContext)) {
            // check Device is Tablet or Mobile
        }
        // opened camera is front or back
        if (frontCamera == Camera.CameraInfo.CAMERA_FACING_FRONT) {
            matrix.postRotate(270);
        } else {
            matrix.postRotate(90);
        }
        width = bitmap.getWidth();
        height = bitmap.getHeight();
        final Bitmap scaledBitmap = Bitmap.createScaledBitmap(bitmap, width, height, true);
        final Bitmap rotatedBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0, scaledBitmap.getWidth(), scaledBitmap.getHeight(), matrix, true);
        final ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        rotatedBitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        final File f = new File(imagePath);
        f.createNewFile();
        final FileOutputStream fo = new FileOutputStream(f);
        fo.write(bytes.toByteArray());
        fo.flush();
        fo.close();
