Do keypad commands come from Android or the manufacturer?

Question

I'm curious if keypad commands like those listed below come from the Android OS or if they're added by manufacturers. On my N1, I know of these two commands:

*#*#checkin#*#* - Phones home to check for updates.

*#*#info#*#* - Enters a detailed phone information menu.

There are many that seem to be "standard", but they can also be added by individual applications (e.g. provider-installed).

Very nice. Thank you! So the real answer is the codes come from APKs, which will vary by device. – Josh Sep 29 '10 at 14:21

I entered ##info## on my Captivate and got to the same menu.

So, in the interest of adding to the list

*#*#1472365#*#* gets you to the GPS configuration menu (not sure what word that works out to)

No, *#*#1472365#*#* doesn't work on the Nexus One – Ben Weiss Sep 20 '10 at 21:13
So that leads me to think the commands come from the manufacturer? HTC has different commands than Samsung? – Josh Sep 20 '10 at 21:25

It's android based, I tried same commands on Moto Droid and HTC myTouch, both worked exactly the same.

Did you try the ##1472365## command that Dr.Dredel mentioned? – Josh Sep 27 '10 at 14:45
Yup, doesn't work on myTouch. I don't have the Moto Droid on me so I can't try it. I guess that's not android default?? – Muhammad Usman Sep 28 '10 at 07:51
