Internal Device HTC Diagnostic Menu

The newer HTC phones as well as a few of the older ones like the original HTC evo 4g have a Internal Diagnostics application available through a special ## code

the code is entered from the dialer as follows *#*#3424#*#* this will bring you to this screen..

After you hit accept you will enter the app.

here you can virtually test any part of the device.

for the battery test the device needs to be at 100% charge with the LED turned to green and airplane mode enabled the test for battery requires on hour to run after 100% charge is completed!

Hope this helps some people out with issues on their HTC phones and troubleshooting as well!
