    N95 Light sensor

    Is there any way to read out the light sensor on the Nokia N95? I mean the one which also regulates the LCD backlight, located on the front next to the front camera.

    AFAIK there no APIs, but you can take a image and analyze its data

    Re: N95 Light sensor

    Will it be possible to ... what? The S60 Platform only has a sensor since S60 5th Edition so whatever it is used on N95 for the light sensor is device specific.

    Have you tried using the sensor API from S60 5th Edition on the N95. Well, it does not work. There's nothing that the platform can release to improve that, open source or not.

    Re: N95 Light sensor

    1. So you say that OS doesn't have any control over backlight intensity and does not get any data from light sensor? It is hardware controlled on N95 (and the like)?

    2. Then what happens to those non-public API's when Symbian is open sourced? Will they be released to public use or remain hidden for ordinary people?

    (2) is easy: you have to distinguish at least 3 things from each other:
    - Symbian OS - this is the one what is going to be open source
    - S60 Platform - this is built on top of the OS
    - device-specific additions - they are built on top of the platform by the given manufacturer.

    Re: N95 Light sensor

    I would add to wizard_hu_'s list a forth layer: your own applications. Will they become open source?

    Open Source is obviously not the solution for all the problems and one has to set the expectations at the right level.

    As for your 1., it is also answered by wizard's post.

    Re: N95 Light sensor

    I should also like to add that S60 is also being moved to open source as well as Symbian OS! It's not likely to help in this case though as the "light sensor" (Ambient Light Detector) will be part of the device specific additions.

    From what I've heard (from the speech at Nokia World) a lot of the low-level adaptation software is also being made available as open source... although that might be misinterpreted. This is only really going to help with future phones (or at least firmware) though, not the existing ones.

    Re: N95 Light sensor

    still, it looks like there is no way to catch the light sensor.

    Re: N95 Light sensor

    As far as I known there was no additional API released for N95 (S60 3.1) in a long while so indeed you should not expect any changes with regards to what can and cannot be done on that device.
