I'd like to assign google now function, long pressing the home button. Everything is ok untill I turn the phone off. When I turn it on, the assignment is missing and I need to do it another time. Any suggestions? Mi5s plus, Developer EU rom 7.6.8
I think disabling smart assistant solves that issue.
If you have titanium backup, then from there, freeze 'Smart Assistant'. This worked for me.
Hope this helps.
