During this year's Google I/O Keynote, Dave Burke introduced a new concept for handling lock screen security. Lollipop's new API allows using smartwatches or different portable devices as trusted devices to determine whether lock screen security is needed or not. In practice, this works by disabling lock screen protection when your phone is within range of your smartwatch--simple but efficient.

Unfortunately for many users, this functionality is only available on Lollipop, so KitKat and Jelly Bean devices have been left in the cold. This doesn't have to be the case, however, as XDA Recognized Developer hazex created an application that lest you disable lock screen protection while your phone is within range of certain Wi-Fi networks, Bluetooth devices, and so on. Options to unlock via NFC or per location will be added in upcoming releases.

Essentially, this functions just like trusted devices on Lollipop, but for older versions of Android. As such, the most important aspect of this application is its ability to work with Android 4.1+. This means that you can use enjoy smarter lock screen security, even if your OEM has decided to abandon support for your device.

While the application itself is normally a paid app, the developer has created a special XDA community version that doesn't need to be purchased in order to have full functionality. It's a nice gift from the developer to all of the XDA community.

Don't waste your time entering your lock screen pattern all the time. Download SMART UNLOCK from the application thread and bypass your lock screen security when on your trusted networks.
