Switch backlight OFF (N6670) : 150$ reward

4 replies · 3,139 views · Started 06 February 2007

Hi to all symbian champion,

It's a VERY serious ask : i KNOW that there's a mean to turn backlight OFF for Symbian OS7.0s (and probably OS8 too).

HAL::Set is not working, nor EKeyBacklightON stuff. The solution is *probably* held in deprecated libraries (dsclient.lib/activitymanager.lib ?) but not sure. :con?

:icon2: I'm tired of losing time, and i'll pay for that solution.

Concerning cheaters : proof of concept needed 🙄

Thank you

Don't know any other way. HAL::Set works for me on 7.0s on a Nokia 9500. Can you post some example code which is not working?

Maybe the N6670 doesn't support turning the backlight completely off. What you can try alternatively is to set backlight to the lowest possible value:

HAL::Set(EDisplayBrightness,0)

Just tried : that does'nt work.

Reverse engineer of dsclient.lib, give me that there's a SwitchLights(int,int) within RDosLights class. But i don't know full prototype...

Is HAL::Set work on Nokia 6600 ?
