The HTC Desire has a secret menu, which can be accessed by entering a special code as if you were dialling a phone number. The menu shows a wealth of interesting information including IMEI, phone number, usage statistics, wifi information, accurate battery voltage and signal strength (the latter being useful to see if you are suffering the ‘smartphone grip of death’).
The code for the secret menu is:
* # * # 4 6 3 6 # * # *
As mentioned above, enter this into the phone keypad as if entering a phone number. There is no need to press ‘Call’.
NB The menu includes a number of tests and configuration options. DO NOT USE THESE as there may be a risk of misconfiguring or damaging your phone.
