HIDDEN ANDROID SECRET CODES



One of the most popular practices amongst
software developers is to leave ‘backdoors’
within the code, which essentially allow
anyone with knowledge to get into the system
at a much deeper level than you’d expect
from an end-user. These backdoors aren’t
always with a malicious intent; most of the
time, they allow the OEM or programmer to
get into the system for troubleshooting when
other, usual modes of access have been
blocked. They can be quite friendly and
helpful if you know what you’re doing.
Smartphones have a good share of these as
well, where they’re generally known as secret
codes. Most of the time, these numeric/
symbolic sequences allow you to access
hidden menus, diagnostic tests, areas that
could change some of the most basic
parameters of your device and whatnot.
These secret codes, in fact, have not been
exclusive to smartphones, but have long been
a part of the dumb-phones and then the
feature-phones before most major OEMs
joined the smartphone bandwagon. For those
devices that run Android, certain codes are
shared across the board, and hence, can be
used on a variety of devices.
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.

in the same code will give PDA and firmware

*#12580*369# – Software and hardware info
*#9090# – Diagnostic configuration

You can find more of these spread across the
internet, and they’re usually very handy to
have, even if just to show off your geekiness
to your social circle.
