Just to add on, I have tried writing a loadable kernel module, but then realised in order to use, the phone must be rooted, modules loading is enabled in config and the kernel version must be similar. Thus have to use a developer phone. All this cannot be done in a phone bought from telcos.
Using NDK is also not feasible as I searched and couldn't find any reference on accessing the camera hardware using native code. I have posted in the NDK section but no reply yet. So I am guessing that it is only feasible through an application. But how do make this application to lock hardware functions?
