    In order to start the HTC function test you open up your dialer and enter:
    *#*#3424#*#*

    This will bring up a menu that has the ability to test each of the following:
    audio
    bluetooth
    charger
    G-sensor
    LEDs
    Line Drawing (screen)
    Camera test
    Wifi Test
    Backlight
    Buttons
    Flashlight
    Headset
    Light-sensor
    Proximity sensor
    Vibrator

    (MOD NOTE: see here in the EVO 3D forum: http://androidforums.com/htc-evo-3d/385159-htc-test-menu.html)

    (Don't mess around too much in these menus, you could cause yourself problems by tinkering too much. Also some dialer codes are for Vanilla only or are carrier/manufacturer specific)

    I needed that one for a "true" factory reset to allow my phone to re-activate when I was having data issues..

    I discovered that *#*#737283#*#* (*#*#RESCUE#*#*) was added with Jelly Bean. It allows HTC LogMeIn access via the HTC Rescue application. It is for HTC technical support use only.

    *#*#76484#*#* (*#*#SMITH#*#*) was updated with Jelly Bean. There is more access to options and settings. I would not recommend messing around with anything in these menus.
