WebOS Hash Codes

Hash codes (so called because they are prefixed and suffixed with "#" 'hash' characters) are entered into the phone dialer to invoke information displays and behaviors on the phone which can not be reached through menu choices.

The hash codes can be found in the following file: /usr/palm/applications/com.palm.app.phone/app/models/DialStringParser.js

HP Touchpad and GSM Pre note
The HP TouchPad is able to use some of the following codes (most notably for logs). In order to use them, you must either add your Skype account or pair with a WebOS phone, and access the dialer under the "Phone and Video Calls" application.

The GSM Pre accepts only some of the following codes. You also have to change the preceding double hash '##' to '#*', e.g. ##HELPHELP# becomes #*HELPHELP#.

Display Information

 * ##DEBUG# (33284) (CMDA only)
 * This opens a "Debug Parameters" page that contains technical data on your current signal and tower connection. Signal strength is given as RSSI, which stands for Received Signal Strength Indicator. The closer to zero the RSSI value, the better the signal.


 * ##GPS# (477)
 * This opens a "GPS Information" page that will give you location, altitude, speed, and accuracy information gathered via GPS. Depending on webOS version this feature may be CMDA only, but there's a patch, available in Preware for that. This feature is known to work on webOS 2.2.

Safe

 * ##TEARMEDOWN# (8327633696) - Not in webOS 2.2.4
 * This enables/disables the "Sticky Dialer" feature. The sticky dialer feature, when enabled, allows the phone app to run in the background.  It is enabled by default.  When it is disabled, the phone application closes when it is not the "focused" card.  This means that if you open the phone app, then go to browse the net, the phone app closes.


 * ##EVDO# (3836) (CMDA only)
 * This opens a "EVDO Mode" page that controls your phone's EVDO Settings. It gives you the options to force your pre into the following options: 1xRTT only, EVDO Rev 0 only, Hybrid Rev 0, EVDO only, or Hybrid Rev A (meaning pick the best available). Hybrid Rev A is likely to get you the best speed, but if you don't have good reception in your area, you may want to choose something else to conserve battery life.
