“Secret” codes for your HTC phone

Well, they’re not really “secret”. Since we know about them…

These codes might not work for carrier/network phones, but most codes work. These all works on regular One M7/M8 that I’ve tested on.

You simply enter the codes below in the dialer (where you make phone calls).



HTC Function test

A function test where you can test functions, good for troubleshooting.


Phone information and testing menu

This is very useful since you got temperature for battery under Battery information.


These are the most common (and working) codes. If there’s more confirmed ones: Let me know.
