Hidden Secret for more info and tests

---

In your phone dialer type: *#*#4636#*#*

This code can be used to get some interesting information about your phone and battery. It shows following 4 menus on screen:

Phone information
Battery information
Battery history
Usage statistics

Try it but I suggest you don't modify anything you are not sure. Use it for view only unless you are sure and you take notes of what you modify (although there's not much to modify)

keys also spell *#*#INFO#*#*

similar to the update check combination of *#*#CHECKIN#*#*

There in first line have fue setting,interesting what they can do...

There also the *#*#3424#*#* code which launches the HTC Function Test Program which allows you to test functions of the phone.

It you open Phone from the home screens, then choose the bottom right icon, you should be directed to a Call History screen. For call duration, hold your finger over one entry and chose View detailed call history.
