Hello everyone!
I am new on this group and possibly this thing was discussed over
here,but anyway I will assume the risk to ask:

I have recently bought a Samsung C100 phone.Looked on the net for some
codes in order to see some information about it.Found a thing I don't
know what is about related to Digital Audio Interference(the code to
activate is - *#DAIENTER#).Can anyone explain me what this DIGITAL
AUDIO INTERFERENCE is about?I looked over the Internet and didn't find
much stuff about it.

Thanks in advance.

Adaptive filtering.

But the fact that this is an undocumented code suggests that the
manufacturer doesn't think their implementation works well enough to be
worth featuring. Caveat hackitor.
