I've read that in Android 9 that this code will return "Unknown".
However from crash reports that I have seen, on some 9.0 devices eg
OnePlus OnePlus 6 (OnePlus6) I think that is returning Null.
So to avoid any Null related issues it might be wise to check for this condition before making use of it.
Just a little observation.

Dim ph As Phone, ID as string
ID=ph.GetSettings("android_id")
