before lollipop I ditched Hi Galaxy for OK Google because Hi Galaxy was unreliable....and OK Google worked all the time very well.
Now in Lollipop I sometimes get a notification that text to speech has an issue. But if I hit the notification it goes away and nothing happens. If I hold down the notification it takes me to battery doctor...wonder why? as there are no settings there for voice.
If I tap a microphone symbol for search, voice input and output seems to work just fine.
But if I say OK Google it used tom open a voice input app...but now in Lollipop, nothing happens.
I have voice activation set to "on".
Am I missing something else?
