I enabled OK Google and added another App to add some extra features.
It will now respond to:
Navigate to postcode/home/Gregs
Play a song or album in Spotify, skip a track etc.
Read out a new text message/compose a text. It even seems to recognise place names, even small villages etc.
Dim the screen to say 25%
Change the volume to a %age
Don’t use it all the time but it is useful when you are driving, and you can just turn the stereo down briefly so the phone can hear your request to read out a new text message and speak a reply without trying to look at the phone at all. You can ‘OK Google’ from the lock screen if you enable it.
You can also do the ‘tell me about Swindon’ in an attempt to entertain yourself and it will read out a wiki summary of whatever subject you asked about.
