Since the m4/3rds camera (thanks to great IBIS) can shoot about a second long
exposure at f/1.7, likely it will take a better night shot than the phone.

not likely, because the phone is using computational photography and
the m4/3rds camera is stuck in the past.

Dpreview compared a night-mode video camera with a Nikon D5. Problem was,
the D5 and the lens they used had no stabilization so it was limited to
1/30th without blurring the image, at 20,000 ISO. Dual IBIS and a 50mm lens
will yield practical exposures of seconds long so unless there is fast
movement in the image, it's a better solution. Not only that, you can drop
the ISO so the image doesn't look like crap.

not relevant.
