ok. thanks for the very verbose log... (just plain journal is enough...)

weird...

In the log you sent me there is no single proximity interrupt...
Even after the restart there is none.

Does the display blank when you place finger over the sensor on right side of the oled, and come back active when removing?
Note, it works better if phone is active, not so well when it sleeps.

I'll add some more diagnostics tomorrow evening.
