Just started happening. I press my home button and nothing happened and then tried to launch google from the app drawer and the icon greyed out and then regained color and never opened. I restarted my Note 4 then. I tried to use ok google and it worked but took like 10 seconds and all my cards are gone. What can I do to fix this? I like using Google Now for reminders, commute info etc and would love a fix asap.
