Smart Settings is an application that lets you alter the user interface of your phone to make it easier to use.
The first thing you can do with Smart Settings is associate your favorite phone apps and games to number keys. This allows you access to your apps in two key strokes. The next feature, Easy Unlock, allows you define the unlock keypad combination, and change the "unlock" message that appears on screen too.
The Auto Lock feature in Smart Settings allows your phone to lock the keypad after a set amount of time, and choose applications that can override this. This is designed to stop accidental phone calls, a problem most people will have had! In Security, you can choose to extend your phone lock code making it harder for people to guess, and also harder to remember.
If you're not happy with your phone's interface, Smart Settings is a neat little application that gives you a bit of flexibility. Personalizing how it works also makes it much harder for strangers to use, so it has some security benefits beyond its security settings.
Smart Settings is a great way to customize your user interface and improve its basic security to boot.
