Of course, there are other security features to check out as well, such as a pattern unlock, or in select cases, fingerprint recognition. The PIN number should be jealously guarded, but is there a way to reveal the PIN number of another person. Apparently so, as researchers have warned that the smartphone's camera and microphone could be vital in doing so.
