    EM sensor can also get a false trigger or a cross call. An o/p interface from the mobile would be a better approach, but that will need a small hardware to sit on the mobile.

    what is that you want to acheive infact?

    To the first reply: i was thinking of modifying my mobile put a small hole in it's cover to show a blinking light when it rang.

    Thanks for the elctrokit link that's what I needed. Looks pretty easy
    Although your right there are some cheap gadgets with them in I think il just buy something.

    Don't modify your mobile.

    They are tested extensively to maintain proper safety against SAR (radiation exposure). Modifying, even in the most seemingly insignificant way(s), may impair it's sensitivity and other factors which will result in adverse operating performance including battery life.
