Smartphone Security Really Matter? The degree to which it matters depends on the individual user, or the individual company. Set your phone to lock, or time out, after a certain period of inactivity, requiring a password to get back in. Android supported only pattern unlock (in which you draw a pattern to access the phone), but with version 2.2 of the OS, it now supports PINs and passwords. If your phone is lost or stolen, you can remotely clear all of your data–including e-mail, texts, and documents–off of the handset.”]
