I observed this thing that when the phone is idle i.e. screen is off and I fire command "OK Google", nothing happens...but when I unlock the phone manually and say OK Google then Google Assistance APP launches... I don't understand this at all.. my phone is up to date, android 9.0 and latest security patch. While reading some articles on various forums, I came to know that OK google won't work on Off Screen after Android 8 update due to security reasons.. But my previous Phones Redmi Note 4 and Moto G6 Plus both are having Android 8 and 9 respectively support this feature even when the screen is off and Nokia 8.1 being under Android one program(Google's premium series) does not support this...
Anyone having a solution on this?
P.S. I have already activated Voice Match Settings like "Access with Voice Match" and "Lock Screen Personal results".
