Samsung - Calculator Secret Codes

In some recent security patches, Samsung disabled the (+30012012732+ gateway for lower-end or carrier-locked models.

You might be wondering: Why use the calculator when I can just dial codes?

I need to compile a comprehensive list of secret codes for Samsung devices. I have several sources that provide lists.
