According to an answer to a related question, using the TRY_HARDER decode hint might help, since it "optmizes for accuracy, not speed":

decodeHints.put(DecodeHintType.TRY_HARDER, Boolean.TRUE);
Result result = reader.decode(bitmap, decodeHints);

If the same image is being correctly interpreted in the online service but failing in your case, it's probable that they have TRY_HARDER on while you have it off.
