Google voice search and Voiceover.

Hi Applevis,
Firstly, I want to take the opportunity to commend you all on the development of a truly beneficial community resource. I'm a relatively recent user of IOS and just thought it may be potentially useful if I drew your attention to what I can only assume is a bug either with the Google voice search app or Voiceover. Yesterday evening I was playing around with Google voice search so I toggled VO speech off. After not getting any response from the app, or triple click home, I attempted to toggle speech on again and my Iphone 6 refused to do anything. In the end, I resorted to asking Siri to enable Voiceover. When VO came up, it had apparently dumped me on the lock screen and the phone had forgotten my touch ID. I was able to resolve things by entering my passcode and redoing the touch ID. For a relatively new user, I found this experience both disconcerting and slightly scary. I've subsequently replicated my actions and have not experienced this odd behavior since. However, I had previously used Google voice search with VO speech turned off and failed to encounter anything strange, so maybe this was an isolated crash, It was incredibly unusual however so I merely wanted to post it on this forum to make you all aware of the possibility of someone having a similar experience.
Best wishes,
Darren.
