whynot This is great!
Just a comment on your phone adb setup instructions:
KaiOS is of no interest here, as its adb is locked down, so if you're going by Android phones, the only 2 with that code are the TCL Flip 2 and the Alcatel Go Flip V
What you wrote for Kyocera applies to Schok, Sonim, and many other phones, so that one could say all other phones.
