I think there is something iffy about that Google app too. I find it useful, but my phone gradually slows down over a period of time. I clear out all the memory being used by the app and reboot the phone. It speeds up for a while, but after a week or two it starts to get sluggish again.
What do I mean by 'sluggish'? Well, as an example, I was watching a film with Jodie Foster in last night. She was made up to look quite old and I wondered how old she actually is**. I whipped out my phone, clicked on the Google app text box, and waited, and waited, and... after about 20 seconds the onscreen keyboard finally popped up!
I cleared the memory and rebooted the phone a couple of hours ago. Let's try again... Yeah, 1 second this time rather than 20!
** I guessed late 50s - correct - 58!
