Your phone's camera is the one you have with you all the time, and as we discovered when reviewing the LG G4, LG's latest flagship has one of the best cameras on an Android phone. So if you want to quickly launch into the camera app, you'll be pleased to hear there's an easy way to do just that — even if the screen is off. And if for some reason you want to do the same with LG's built-in QMemo+ note-taking app, that's also just a button press away.

The basics The LG G4's shortcut keys feature lets you launch one of two apps immediately, even if your phone's screen is off, or secured using lock screen security. With the screen switched off, or the lock screen showing: Double-tap the volume down key to launch straight into the camera app. By default, with the "Quick shot" feature enabled, this will also immediately take a photo when the app loads.

Double-tap the volume up key to launch the QMemo+ note-taking app, and draw or write a new note. It's worth noting that if you do have lock screen security enabled, you won't be able to view previously saved photos when launching the camera app through its shortcut key. And for obvious reasons, neither shortcut key combo works once the phone is fully unlocked. Verizon is offering the Pixel 4a for just $10/mo on new Unlimited lines
