Disabling the Screen Lock on Android

Friday, November 28, 2008

Most embedded mobile devices have an option to automatically lock the interface when idle to prevent accidental access, and the Android-powered G1 is no exception. Interestingly, some people actually want to disable this feature. There’s no direct interface to this setting, however. While tinkering with the Setup Wizard applet, I may have stumbled upon a hack.

  1. using AnyCut, create a shortcut to the activity “Setup Wizard”
  2. launch “Setup Wizard”
  3. unplug+replug the battery and power on the device

The applet apparently disables the lock and re-enables it when it finishes. I wanted the screen lock back so I simply ran “Setup Wizard” again, this time completing the procedure.

Note that this method also disables the manual lock triggered by pressing the End button.

    And it disables Home, and it mostly disables Call, and gawd knows what else it does.

    That’s pretty interesting. I suppose this warrants additional investigation.

    I just verified…

    Doing this disables your “Home” button, and your green “Call” button. Not worth it in my opinion… two commonly used buttons that I personally, am not willing to sacrifice to save myself one “Menu click”
