The LG G3 is bundled with a software that offers a number of useful features. After the Android Lollipop OS update, some of its primary features were either transformed or completely removed, but even so, there is still a lot to explore, including a capacity to launch apps on multiple screens as well as increased accessibility. Here are just a few LG G3 features you can take advantage to optimize your experience:1. Explore its Knock FunctionalitySome of the LG G3's hidden features require tapping to make them functional. For example, by double tapping an empty spot on your screen can switch your display on, if on standby mode or off, when the screen is active.Furthermore, rather than using the usual pattern lock for locking or unlocking your device, you could employ a knock code instead and still be able to tap to wake the device display screen.2. Guest mode third-party restrictionsIf you want to restrict certain apps to third-party users or intruders, then Guest mode will come in handy. This means you can give your phone to a loved one and not worry about them snooping through your private stuff.While in guest mode, the LG device also disables the notifications bar and app drawer. A knock code can also be set up for easier disabling of the guest mode. Simply head to your Settings >> Personal >> Guest mode and select your options.3.  Navigation buttons adjustmentsYou can easily change the position of the navigations buttons to your preference on the LG G3. Go to the Settings >> Display >> Home touch buttons >> Button combination. Here you can drag and drop the keys to the position them where you see fit, you also have the option of hiding them when you are not using them.4. Shortcut to Camera and notes appsThe Volume Keys can be applied to get quick access to two different apps while your device is on standby. By simply long-pressing the Volume down button, you can launch the camera while to launch the notes app, you can simply long-press the volume up button.However, if you have set up pin, pattern or knock code protection then you'll first need to unlock your G3 device before navigating to the launched app.5.  Simultaneous use of two appsLong-pressing the back button launches a dual-window functionality which allows viewing of multiple apps on your system on a single screen simultaneously. This includes apps such as maps, email, and the browser.To the upper or lower half of your device's screen, drag and drop the two apps you need. The size differences between the two apps displayed on your screen can easily be adjusted with a drag of the bar in the middle.6. Better accessibility with Touch AssistantEssential functions such as settings, volume controls, power On/ Off, back and home can be accessed through an additional button that can be positioned on any spot on your screen and across all windows.To enable, go to Settings scroll to the General option, choose Accessibility then select Touch Assistant. The button will now pop-up on your screen and will display a variety of key functions once you tap on it.7. Smart Screen FunctionalityYou can enable the Smart Screen function which allows your screen to remain lit for as you are using it. This applies especially when you are reading or are constantly checking out something on your device.To take advantage of this, head to Settings >> Display and enable Smart screen.8.
