What Does Dialing ##21# On Android Do?

Perhaps like many other phone users, you have seen one or more messages about how the ##21# code is used to find out if someone is monitoring your cell phone. The claim is that when you type either of these two codes on your Samsung phone, or other Android phone, if it displays that a list of features are enabled, that is proof that your phone has been tapped.

In some of these messages, users are told to discard their phones after this test returns positive. But is this claim true? At all. This claim is a hoax. Dialing this USSD code on any type of cell phone does not tell you whether your phone has been tapped or not.
