What follows is a collection of some of the secret
codes common to the Android platform. All of these would be entered
through the phone dialer (just punch in the sequence as shown). Since
most hidden menus are manufacturer specific, there’s no guarantee that
they’ll work across all Android smartphones, but you can try them out
nevertheless on your Samsung, HTC, Motorola, Sony and other devices. Be
advised, though, that some of these can cause serious changes to your
device’s configuration, so don’t play with something that you don’t
fully understand.
