Bangle.js 2 main board.

I was wrong, again :)

You are correct, it is indeed pin D7 that gets interfeared when I touch my finger on the "button" area.

When it was bricked and I had it on the charger, the screen would stay on as long as I had my finger on the "button" area.

but when it was not on the charger, I could get it to turn on the display for a moment only if I run my finger across the "button" area fast.

I can replicate this now if I do:

D7.mode("opendrain"); 
D7.write(1);

so you were correct, it is the D7 pin that somehow can be interfered with.
