LG G4: Problem with the "KnockOn(double tap to wake)" Function

Hi Everyone

I have a LG G4 mobile with Sr No : S/N :507KPHG695248.

Since today morning I face the problem with the "KnockOn" Function.

LG's smartphones have long featured the so-called KnockON function. It's what you would call a "double tap to wake" – when the phone's screen is off, you just tap on it twice, and the device wakes up. Alternatively, if the phone is on, you knock twice on an empty spot in the home screen and it will go to sleep.

But in my phone many a times "double tap to wake" is not responding. Even the power button does not respond simultaneously.

I try these two ways to awake my phone:

1) insert the charger pin & phone awakes immediately.

2) take out the battery & replace again & start the phone.

Kindly suggest a proper solution.

I think you can turn it off and on maybe it's turned off. Or did you install a custom launcher app maybe?

If it somehow got turned off, this is how you can turn it back on (or verify that it is on).

You will need a way to create a shortcut to the system setting that controls the KnockOn-KnockOff. I have used QuickShortcutMaker, free from the Play Store https://play.google.com/store/apps/details?id=com.sika524.android.quickshortcut, but I am sure that there are a lot of those kind of apps. Some launchers also let you make shortcuts to system selections.

Open the app and hit NORMAL SEARCH. Type KNOCKON, and you should see SETTINGS with a blue icon. Tap the icon and select the first entry that says KNOCKON. If it is turned off, turn it on. If it is on, then turn it off and then turn it back on. You can save the shortcut to your home screen if you want. I recommend that you clear the cache and reboot when you are finished.

Tools like this one also let you get to a lot of other system settings and such, so be very careful when you are accessing some of these settings. If you're not sure about what this or that does, don't change it. Google it. If your search comes up empty, ask in the forums. Someone will know the answer.
