An open padlock in the upper right-hand corner of the screen indicates that the passphrase is cached, and the phone is potentially insecure. Users should note that they can quickly un-cache their passphrase from the notification center. This is why it's important to a time limit for how long the app can keep your passphrase cached (more on this later). While this does make using TextSecure much easier, it does mean that your messages are completely visible on your screen-potentially without warning. More importantly: when you receive an encrypted message from another TextSecure user, if you've recently entered your passphrase to the app, the message will appear in the notification center in plain text. On my Samsung Galaxy S III I was able to capture a screenshot of the set up procedure, but the app only allowed all-black screenshots later. However, users should note that this behavior is not consistent across all Android models. When reviewing apps, I like to take screenshots of the setup process so I can refer to them later I was pleased to note on the Samsung Galaxy Note II that the app prevented me from grabbing screens, both during the set up process and once the app was running. TextSecure aims for truly end-to-end protection, encrypting your messages at rest on your phone, and when they're flying through the air. Your original messages will remain in their existing location, though TextSecure gives you the option to delete them. That way, even old messages on your phone will be unreadable to anyone attempting to access them. Upon startup, the app prompts you to create a passphrase and then copies your existing SMS and MMS messages into a new encrypted database.
