I set up the Moto Voice on my Moto X pure.......it said to say "talk to me" and enables spoken caller ID and will read incoming texts for 30 minutes hands free? Why just 30 minutes? It should announce caller ID and read texts as long as my bluetooth is connected.....and without bluetooth for as long as I have my phone on and the feature turned on. I went through all the settings and couldn't find anything I missed. Do I need to turn on Moto Voice and talkback under accessibility as well? What am I missing?
