How to read serial number on a Samsung device (from within app / on the device)?

Question

How to read the device serial number (not IMEI) of a Samsung Android phone (same value that you get when you call 'adb devices') but from within an app or from the device; not using PC/USB/adb.

I found a solution for HTC and other devices, which is - to call

getprop ro.serialno

in a terminal

as described here,

but it doesn't work on a Samsung Galaxy S.

Answer 1

I conclude that it's not possible on Samsung.
