I think I may have accidentally discovered an Easter Egg on my new V35 ThinQ.
I was looking for a way to update the firmware when I did the following:
1. Go to Settings | About
2. Double-tap "About". Brings up a stacked yellow button.
3. Press/Hold white button. A floating Android squid appears.
Squid can be moved by dragging.
Just sharing the info in case no one else knew about it. If it matters, this is under Android 8.0.0.
