How to Get “Ok Google” Voice Shortcut on Galaxy Note 4
Here is a clever trick that will let you get the “OK Google” voice shortcut set up on all of your Galaxy Note 4 screens. You can set it up for your lockscreen too and control your phone using the hands free launch phrase ‘OK Google’ followed by a command, even when your phone’s screen is locked.

Before you get started with the trick, it might be noted that the Samsung Galaxy Note 4 is available with Qualcomm’s Snapdragon 805 (APQ8084) processors and Exynos 5 processor. This trick works perfectly with Qualcomm chip based Galaxy Note 4 only, because this processor has always-listening capability, even when your phone’s screen is locked and without draining your battery.
