2 hours into the first use, guess what?
I can’t believe it. Exactly the same spot, top left corner, a ring the same size as though it’s being touched. By the time I started filming the touch wasn’t there anymore but the unlock curtain was still reluctant to scroll up so I had to restart the device. Pulled the screen protector off just in case it’s related to that (exit stage left TWO nice shiny screen protectors now…) so I’ll see if it comes back. But not the start I was looking for with this new baby. The device continued to have this problem over the weekend so the video is a montage of several clips I took.
Last thing last night I did a device refresh just on the offchance it’s related to a firmware update (though my last device faulted all the way through various updates), will see if it changes anything.
