Re: [android-developers] Re: what needs to be change to enable call recording on android platform?

Ugh... Please read about how mobile phone modems work before you
trash Android for a requirement enforced by carriers.

It has nothing to do with the *platform*: it has to do with:
- US laws governing voice recording of calls.
- The fact that modems on *all* phones, not just Android, not just
windows phones, not just iPhones, not just anything else are disjoint
from the platform, they *all* go through the modem.

There's no such thing as a "phone device driver", there's a modem that
you use to talk to people, and Android merely interfaces with it by
saying "call this person, send a text, etc..." It's a thin interface
that is presented by all mobile platforms, not just Android.

So why all the proprietary code in phones? No proprietary code on
Android: nothing in the platform controls the phone, that's the modem.
Seriously, look in the Android source tree, there's no code to
control the phone itself. Is there code to interface to the modem?
Yes! Is it open source? Yes! So I don't see what you mean...
