It appears as an orangish box across the bottom of the wake-up screen you see before you enter your password or the facial recognition opens to your normal Home Screen. In the box is a horizontal bar like for a video with a play triangle or pause button, but nothing happens when you touch them and it toggles back/forth. To the left is a small spiral arrow that says minus 10 and to the right another that says plus ten, and the bar above shows 31 s I believe. If you swipe up it disappears when Home Screen opens but comes back if you push upper right button to relook phone
There is a web page that explains lura.live in terms too technical for me to understand, but it seems to be about stopping pop ups and other browser action. Found that in Google.
I found nothing useful relating lura.live to the OS 16.1.2, nor anything related to it in my settings.
I shut down all my apps and the box stopped appearing on the wake-up screen, but I still don’t know if I should be worried or if it was a bug that died when apps like safari and gmail were closed
