How to Find the HTC Touch Pro2′s Hidden Field Test Mode (Signal Strength Diagnostic)

So, you want to know more about your HTC Touch Pro2′s radio signal quality? Here’s how to get to its hidden Field Test Mode…

1. Bring up the dialing keypad
2. Press *#*#364#*#*
3. Press “Talk”

You should see a screen similar to the one above appear. I’d like to claim that I discovered this through painstaking research. However, the truth is I read an article in Popular Science that discussed the Field Test Mode available in phones and noted in my personal blog. I kept a link there to a PDF document over at wpsantennas.com that maintains a list of known Field Test Code activation sequences for a variety of phones. I simply tried one of the key sequences for other HTC phones to find the one that works with the Touch Pro2.
