I just switched from an iPhone, and I want my android to have the same behavior as iOS where you hold the home button, and siri starts listening.

With my android, I have to wake up and unlock the device, then hold the home button to get to the google now screen, then I have to either say "okay google", or hit the microphone button.

This process takes way longer and makes voice commands in the car unsafe, which is primarily what I used siri for

Please any help would be appreciated

In Google Now, click the menu icon on the left of the search bar (it looks like a hamburger).

Then choose Settings -> Voice -> "OK Google" Detection.

'OK Google' Detection screen

Flip the three switches on. When you switch on the second one, the app will ask you to say "Okay Google" three times to train the voice model. Flipping the third switch on will prompt you for the password to your phone.

Now, when you say "Okay Google", the screen will be unlocked.

    This isn't the same as the iOS Siri behavior. This is enabling Google's listening for "OK Google" at all times. iOS has an option to listen for "Hey, Siri" at all times, too. But the original question here appears to be asking how to hail Google Now simply upon long-press of home button from lock-screen.

In Android, by default, you can't have access to Google Now when the phone is locked (maybe for security reasons), but there could be a lock screen widget for that. You can search for that.


On my Samsung S6 this is how I did it:

settings > personal > lock screen and security > info and app shortcuts > app shortcuts > left shortcut > voice search

Now from the lock screen I can drag up from the bottom left and google starts listening.

note: Unfortunately if you have a password lock, you have to unlock the phone before it will answer your question.
