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.
Yes, the Galaxy Note 4 has Samsung’s “S Voice” assistant for hands free operation, but it is far behind the “Google Now” voice assistant. Therefore, by adding OK Google voice shortcut on your Galaxy Note 4 you will get Moto X’s like touchless feature.
1. Open Google Search settings -> Voice -> Languages and set it to “English (US)”
2. Then, enable “Audio History”
[Above settings are necessary to start voice search from any screen]
3. Now, select “Ok Google” and enable the option “From any screen”. You will see Samsung’s S Voice popping up,
just tap the mic button and train the app with “Ok Google” hotword.
[Train your Note 4 in a quiet room. Also, keep your phone at least half a meter away from you]
4. Once you have done training voice model, enable “From lock screen” option.
Now you are set up to search from wherever you want. Enjoy!
